2.1 INTRODUCTION
The goal of nutrition intervention is to supply adequate nutrients to meet the patient’s
nutrient requirement by the most physiologic, safety and cost effective route. Sometimes
person cannot eat any or enough food because of an illness. The stomach or bowel may
not be working quite right, or a person may have had surgery to remove part or all of
these organs. Under those conditions, nutrition must be supplied in a different way i.e
through enteral and parenteral route. In this practical we shall review these special feeding
methods, with special focus on enteral nutrition. What are the benefits and indications for
enteral nutrition? What are the enteral feeds and their characteristics? How to prepare
home-based blenderized formulas? These are a few aspects covered in this practical.
Objectives
After undertaking this practical, you will be able to:
differentiate between enteral and parenteral nutrition,
indicate the conditions when special feeding is required,
discuss the types of enteral feeds, and
prepare blenderized feeds for patients.
Having gone through the types of enteral feeds, it is important to understand that functional
status of the GI tract and absorptive capacity are the predominant factors in choosing a
formula. Other considerations include: nutritional status/medical therapy, renal function,
fluid tolerance/electrolyte balance, and route of delivery. Formulas are categorized
according to their type and amount of protein and calories; some are tailored for different
disease states. It is important that we have a thorough knowledge about these special
formulas before being involved in the selection of formula and substitution of a product, if
necessary. You would realize that different types of enteral formulas are commercially
available for use with critically ill patients. Here, however, our focus will be to get a better
insight into blenderized formulas which can be easily prepared at home. Let us review the
blenderized feeds in greater details. But first, we shall study about the nutrient requirements
of enteral nutrition.
Energy : Most of the formulas provide 1.0 - 1.2 Kcal/ml. In high concentrations,
they may provide 1.5-2.0 Kcal/ml and are used for patients who have elevated
calorie needs (ranging from 30-35 Kcal/kg). Most individuals generally require a
range of 25-35 Kcal/kg of body weight/day.
Proteins in enteral formulas provide 4% to 32% of total calories. Those formulas
providing 18 to 32% of calories are considered high-protein solutions. Protein
requirements (for adults) usually is 1g/kg body weight/day, with modifications
19
Clinical and
Therapeutic Nutrition (seldom >1.5 g/kg body weight/day) to account for increased needs due to healing
wounds, or acute or chronic disease. If a patient is malnourished, nutrient needs
may be greater at first to restore nutritional status. Protein sources are provided
as intact proteins (egg white solids), protein hydrolysates or crystalline amino
acids. Predominate sources of protein include soy and casein.
Carbohydrates contribute 40% to 90% of total calories in enteral formulas.
Carbohydrate sources used in formulas are pureed fruits and vegetables, corn
syrup solids, corn and tapioca starch hydrolysates, maltodextrins, sucrose, fructose
and glucose.
Fats/Lipid provides 1.5% to 55% of the total calories of enteral formulas. The
principle source of fat includes vegetable oils, medium chain triglycerides (MCT),
lecithin, and mono - and diglycerides.
Vitamins and minerals are essential components of enternal formulas. They
generally provides 100% of Recommended Dietary allowances (RDA). Different
pathological conditions may require high or low amount of micronutrients.
Water recommended:
Now that we have a good knowledge about the different types of enteral feeds and their
nutritive content, let us focus in greater details on blenderized feeds.

3.1 Introduction
3.2 Fevers: An Overview
3.3 Different Types of Fever
3.3.1 Acute Fever
3.3.2 Chronic Fever
3.3.3 Fevers of Unexplained Origin
3.1 INTRODUCTION
Fever is a symptom and not a disease itself. It is a response to stress, trauma or
altered immune/metabolic system of the body. Since fever can develop in association
with several forms of trauma, communicable/non-communicable diseases; dietary
modifications may be required keeping in mind the nutritional demands imposed by
fever and other associated diseases. Therefore, in this practical, we shall learn about
the nutritional implications of fever and the dietary management of different types of
fevers. We have already studied about fevers and their management in the Clinical
and Therapeutic Nutrition Theory Course (MFN-005) in Unit 3. We suggest you look
up the unit once again and refresh your knowledge before you get down to this practical
and the activities included in this practical.
Objectives
After undertaking this practical, you will be able to:
describe the different types of fevers,
explain the impact of fever on the nutritional status,
discuss the dietary management of different types of fevers, and
plan diets for patients suffering from typhoid and tuberculosis.

Thermo-regulatory center in anterior hypothalamus

Fever
Let us now brief ourselves on the various forms of fever and the common terms
associated with fever.
Energy: During typhoid, there is a peak rise (as high as 104F) in the body temperature
during the first phase (7-10 days) followed by a plateau and then a decline. The
BMR also increases in proportion to the elevation of body temperature which results
in loss of muscle and fat mass as alternative sources of energy. Thus, the diet should
provide enough calories to prevent the onset of negative energy balance. Most of the
non-ambulatory patients benefit by increasing the energy intake by 10-20% above
the RDI.
Protein: A high protein intake which provides 1.5-2.0 g protein/kg body weight/day is
recommended during and immediately after the recovery from infection to reduce
the risk for reoccurrence. During the active phase of typhoid there is massive
destruction of body tissues to release energy (food intake being low). A high protein
diet is also required to ensure rapid healing of peyers patches. High biological value
proteins such as milk/milk products, eggs, meat, marine foods, chicken, pulses and
legumes should be included in liberal amounts. If the patient is on a full fluid diet,
good amount of milk and beaten eggs can be included. However, if diarrhoea/
abdominal distension is severe, milk intake may need to be restricted.
Minerals: Although the requirement for all minerals increases but that of calcium,
phosphorus, iron, sodium, potassium and chloride are particularly high. Incorporating
liberal amounts of milk/whole milk products, green leafy vegetables (particularly
Bengal gram leaves), chirwa, jaggery and a variety of fruits can help in increasing the
mineral content of diet. If there is severe diarrhoea and/or there has been considerable
amount of sweating during the progressive phase of typhoid; oral rehydration therapy
(ORS) and high mineral beverages should be initiated.
We will now quickly brief ourselves on the important aspects of meal planning
(when and how to provide the above discussed nutrients to the patient). Improper
meal timings/inappropriate selection of foods, cooking methods or mode of feeding
can be a determined factor in the outcome of the disease. Hence, few special
considerations are highlighted herewith:
Special Considerations
High energy, high protein, bland diet, moderate in fat and fibre with plenty of
fluids should be given to the patient.
During the first 2-3 days when the fever is very high and/or inflammation of
peyer’s patches is severe, a full-fluid diet followed by a semi-soft diet needs to
be given. Full-fluids (soups, juices, coconut milk/water, egg nog, milk based
beverages etc.) may be given at every 2-21/2 hour, interval throughout the day.
Most of the patients remain anorexic during and even after recovery from typhoid.
It is, therefore, important that the dietician attempts to stimulate interest in the
meals by creating variety in terms of colour, texture, taste and mouthfeel. This is
particularly important for paediatric patients. Wherein meals should be served
attractively such as sprinking crushed orange/strawberry flavoured sugar candy
on beaten curd, incorporating leafy vegetables in cutlets (baked), roti, burfi etc.,
using jam/honey toppings on desserts, fruits, milk shakes etc. preparing
sandwiches in different shapes etc.
Isolated proteins such as soya, casein, whey can be sprinkled/ mixed with
already prepared/ ready-to-serve dishes. Commercially available high energy
high protein supplements such a complan, horlicks, build-up etc. can also be
given. Enteral feed formulas may be used if the gastrointestinal functions are
severely impaired.
With a brief review on typhoid, let us now study about the dietary mangement of
tuberculosis, which we learnt, is a chronic type of fever.

B) Dietary Management Tuberculosis Nutr itio nal
Management of
Fevers
Keeping the clinical implications and impact of tuberculosis on nutritional status in
mind, let us identify and outline the objectives of dietary management.
Objectives of Dietary Management
The objectives of dietary management of tuberculosis is:
to create positive energy and nitrogen balance,
to help in replenishing the depleted nutritional reserves,
to maintain an optimum nutritional status during the period for treatment, and
to accelerate recovery and help in proper rehabilitation of the patient.
We can meet the above objectives by making suitable modifications in the nutrient
intake and food choices of the patient. There may also be a need to bring about
changes in the behaviour/ life-style (if required). Subsequent discussions will be focused
on dietary/nutritional modifications and diet pattern. Let us begin by reviewing the
nutrient requirements during tuberculosis.
Protein : There is considerable wasting of body tissues during chronic fevers because
they are utilized as alternative sources of energy. Majority of the patients have low
muscle mass and depleted serum protein levels. Patients benefit by taking 1.2 to 1.5 g
protein per kg body weight per day. Proteins of high biological value such as those
present in milk, curd, yoghurt, khoa, meat, chicken, fish and other marine food, pulses
and legumes can be taken in good amounts. However, if the patient belongs to low-
income group, it is important to counsel him/her regarding cheap sources of protein
such as incorporating milk, curd, Bengal gram, peas (seasonal) in their diet. Adopting
sprouting, fermentation and combination of cereals with pulses or milk etc. can help in
improving the quality and bio-availability of meals.
Fat : Fat intake should remain normal (20% to 25% of total energy as recommended
for a non-tuberculosis healthy adult/child). Emphasis should be laid on invisible, medium
chain triglycerides and emulsified fat if the patient is suffering from gastric discomfort.
Fried foods and high-fat snacks (poories, bhatooras, pakoras, kachories, samosas etc.)
need to be avoided. Including some amount of fat helps to ensure adequate intake of
fat-soluble vitamins and also make the meals nutrient dense/palatable.
Carbohydrate: Around 60% of the total energy should be provided from carbohydrates
to promote positive energy balance (to ensure weight gain) and spare the proteins for
anabolic processes. A combination of simple and complex carbohydrates should be
included, but care should be taken that the diet contains moderate amount of fibre in a
soft cooked form. Thus, whole cereals such as jowar, bajra, cracked wheat, oats
should be softened/cooked well (serve bajra kheer, cracked wheat porridge, bajra/
cracked wheat, khichdi etc.).
Minerals: Majority of TB patients are chronically under nourished and suffer from
deficiencies of several minerals. Good amounts of milk/milk products and whole
35
cereal/ pulse products should be included to provide adequate amount of calcium and
Clinical and phosphorus. This is essential for the healing of tuberculin lesions and also to replenish
Therapeutic Nutrition depleted reserves of calcium. Iron deficiency due to poor absorption, iron deficient
diet and/or haemorrhages is also frequently observed. Economical measures such as
sugar with jagerry, consuming good amounts of seasonal fruits and vegetables, lotus
stem (dry), chirwa (flattened rice), jowar, bajra, roasted Bengal gram, lentils, animal
foods, particularly liver (haem iron) can help in improving the iron status of the patient.
Vitamins: Patients suffering from tuberculosis generally have depleted levels of all
water and fat soluble vitamins. In order to ensure adequate absorption of calcium and
in view of the impaired conversion of -carotene to retinol, the diet should provide
good amounts of vitamin D and A, respectively. Therefore, we should include liberal
quantity of milk/milk products and some amount of animal food (eggs, meat etc.).
Among the water-soluble vitamins; folic acid, vitamin B6 and ascorbic acid should be
provided by including liberal amounts of seasonally available fresh vegetables and
fruits.
Fluids : During the progressive phase of tuberculosis when the body temperature may
be around 39C, there is considerable breakdown of muscle tissues. This tends to
increase the workload on kidney’s for excreting high amounts of nitrogenous waste
products. Thus, the patient should consume more than 1.5 litres of water everyday.
The fluid intake should be particularly high if they are also suffering from diarrhoea.
Small, frequent, nutrient dense and easy to digest meals should be given during
tuberculosis.
Majority of the patients (particularly LIG) suffering from tuberculosis have limited
purchasing power. They should therefore be counseled effectively regarding the
low-cost nutritious foods available in their region such as red palm oil, spirulina,
Bengal gram leaves, lotus-stem, dates, guava, jaggery, jowar, bajra, chirwa, milk
and milk products (prepared at home-curd etc.). They should also be made to
understand the benefits and process of sprouting/fermentation and combining
cereals with protein rich foods. Preservation of seasonal vegetables such as
drying of raddish leaves/curry leaves, pickling etc. may also be advocated.

4.1 INTRODUCTION
In view of the rapidity with which traditional diets and life-styles are changing in many
developing countries, it is not surprising that food insecurity and undernutrition persist
in the same countries where chronic diseases are emerging as major public health
problems. The epidemic of obesity with its attendant co-morbidities – heart disease,
hypertensions, stroke and diabetes – is not a problem limited to industrialized countries.
Inability to gain weight/achieve and maintain an ideal (normal) body weight is a big
public health issue which needs to be addressed to, especially in view of its association
with IUGR (intrauterine growth retardation), low birth weight and hence an intra-
generational increased risk for the development of chronic degenerative diseases and
early mortality.
Thus, in this practical, we shall learn about the various practical aspects of weight
management. We shall begin with a briefing on the various components of weight
which shall be followed by different forms of weight imbalance.
We will also learn about the various methods which a dietitian can employ for quick
evaluation/assessment of overweight/underweight. The various principles of dietary/
life-style management will be followed by a few review exercises and planning of
diet(s) to help you in learning/improving your skills pertaining to the overall assessment
and management of under/overweight conditions in a spectrum of physiological/clinical
situations.
Objectives
After undertaking this practical, you will be able to:
discuss the components of body weight and the concept of weight management,
describe the conditions linked with weight imbalance,
explain the methods of assessment of weight imbalance,
elaborate on the principles of dietary management for the weight imbalance
conditions, and

4.2 INTRODUCTION TO WEIGHT MANAGEMENT Weight Management
Body weight, as we all know, is the sum of bone, muscle, organs, body fluids and
adipose tissue. Some or all of these components are subject to normal change as a
reflection of growth, reproductive status, variation in exercise levels and the effects of
ageing. Achievement/maintenance of an ideal/normal body weight involves a complex
interaction of several physiological (normal, hormonal and chemical) and/or
environmental (dietary and life-style) factors. Alterations in the above mentioned
factors causes changes in the body weight components and hence fluctuations in the
weight of a person.
Thus, before we proceed to learn in-depth about the various aspects of weight
management, let us clearly understand the various components which contribute to
the total body weight of an individual. This information shall help us in understanding
the inter-relationship between nutrient intake and physical actually vis-à-vis body
composition.
Components of Body Weight
Body weight is often described in terms of its composition. According to the most
commonly used “two-compartment model”, body weight is comprised of two parts
namely:
i) Fat-free mass (FFM)
ii) Fat mass
i) Fat-free Mass literally means tissue devoid of all extractable fat. It is very
frequently used in close association with the term . “Lean body Mass” which
includes parts of the body free of adipose tissue i.e. skeletal muscles, water,
bone and a small amount of essential fat in the internal organs, bone marrow and
nerve tissues. FFM is higher in men than in women, increases with exercise, is
lower in older adults and is a major determinant of the resting metabolic rate.
ii) Fat Mass, which is a critical factor for weight management, can be categorized
as either “essential” or “storage”. Essential fat, which is necessary for normal
physiologic functioning, is stored in small amounts in the bone marrow, heart,
lung, liver, spleen, kidneys, muscles and lipid-rich tissues in the nervous system.
Nearly 3% and 12% of the total body fat is considered to be essential among
men and women, respectively. The range of total body fat (essential fat plus
storage fat) associated with optimum health is 8% to 24% in men and 21% to
35% among women.
Mentioned in Box 4.1 is the Behnke’s Theoretical Body Composition Model which
gives normal ranges of various body components for men and women.

c) Comparison of the actual/present body weight with usual body weight. This
is a useful parameter for critically ill/ hospitalized patients especially to indicate
weight loss (if any). Comparison of present and usual body weight helps to
assess immediate/recent changes in the weight status. Weight loss (lbs/kgs)
reflects an immediate inability to meet nutritional requirements and thus may
indicate nutritional risk. The percentage of weight loss is highly indicative of the
extent and severity of an individual’s illness. It can be classified as follows:
Significant Weight Loss 5% loss in 1 month, 7.5% loss in 3 months, 10% loss in
6 months.
Severe Weight Loss > 5% loss in 1 month, > 7.5% loss in 3 months, >10%
weight loss in 6 months
The minimum necessary actual body weight required for survival is 48% to 55%
of usual body weight.
d) Calculating the Body Mass Index and comparing with standards. The Quetlet’s
Index (W/H2), the most widely used height weight index, is commonly referred
to as Body Mass Index (BMI) and is a validated measure of nutritional status. It
is a measure of relative body fitness and can be computed by using weight
(kgs); (minimal clothing) and height (metres, without shoes).
BMI = Weight (kg) / Height (m2)
The computed BMI can then be used to identify the level of under/over nutrition on
the basis of the WHO classification as given in Table 4.2 and Table 4.3.
Table 4.2: Weight status according to BMI

Waist and hip circumference: Waist is measured around the navel. Hip is
measured around its broadest part. A measurement of waist greater than 40
inches (100 cm) for men and greater than 35 inches (90 cm) for women are
independent risk factors for disease when out of proportion to total body fat.
Waist to hip ratio (WHR) serves as an important tool to assess the type of
obesity. A WHR of > 1.0 for men and > 0.85 for women is an indicator of
abdominal obesity.
Mid-arm circumference (MAC) : Combining MAC with TSF (tricep skin fold)
measurements allows indirect determination of the arm muscle area (AMA) and
arm fat area (AFA). The AMA, or bone free muscle area, is a good indication
of lean body mass and thus an individual’s skeletal protein reserves. Refer to
Figure 4.3 and 4.4 which illustrates the arm anthropometry for children and adults,
respectively. Using this graph, you can measure the fat area and/or the muscle
area. 55
Clinical and
Therapeutic Nutrition
To obtain muscle
circumferene:
We shall now discuss in detail the overall dietary and life-style modifications that can
help an individual/patient in attaining and maintaining a desirable body weight. Let us
first begin with our discussions on dietary management of overweight/obesity.
In this sub-section we shall learn about the various essential features of weight reduction
diets. As a dietitian our objective should be to help the patient reduce weight gradually
without suffering from muscle loss or micronutrient deficiencies.
In order to fulfill the above objectives, we need to bring about following nutritional
modifications.
Energy: There is convincing evidence that a high intake of energy coupled with a
sedentary life-style results in a positive energy balance which leads to excessive weight
gain over a period of time. Thus, the energy intake needs to be reduced to promote
weight loss. It is advisable to reduce weight at the rate of 0.5 to 1.0 kg a week for
which we need to restrict the calorie intake by 500 Kcal to 1000 Kcal per day,
respectively. The amount of energy restriction as per the rate of weight loss can be
calculated as follows:
1 gram of dietary fat provides 9 Kcal
1 gram of body fat (adipose tissues) provide 7.7 Kcal.
Therefore, a 500 gram of weight reduction would be equivalent to 500 7.7 Kcal
i.e. 3,850 Kcal.
Thus, to facilitate ½ kg (500 g) weight loss in a week, we need to reduce energy
intake by 3850 divided by 7 i.e. 550 Kcal/day from the RDI or usual dietary
intake.
Similarly, if we want to reduce 1 kg (100 Kcal) in a week (7 days) we need to reduce
energy intake by 3850 + 3850 = 7,700 Kcal divided by 7 = 1,100 Kcal/day the RDI or
usual dietary intake.
However, the energy intake should never be restricted to less than 1000-1200 Kcal
for women and 1500-1800 Kcal for men as drastic calorie restrictions may cause
weakness, deficiency of several nutrients, nervous exhaustion and disturbances in
57
various metabolic processes.
Clinical and Thus, the energy intake for an overweight/obese patient can be computed by two
Therapeutic Nutrition methods:
i) Reducing around 500 Kcal/day from the usual dietary intake if the patient is
overweight (weight loss rate = ½ kg per week) and 750 Kcal to 1000 Kcal/day
from the usual dietary intake if the patient is obese (weight loss rate = 1 kg per
week).
ii) Calculating the energy intake based upon the activity and ideal body weight of
the patient by using the values of kilocalories prescribed per Kg IBW for obese
individuals as indicated in Table 4.5.
Table 4.5: Daily energy requirements based on body weight and activity
Energy Requirements
(Kcal/kg Ideal Body Weight/day)
Sedentary 20-25 30 35
Moderate 30 35 40
Heavy 35 40 45-50
Protein: Around 20% of the total energy (modified) should be provided by proteins.
Providing adequate amount of proteins helps in:
Good quality proteins rich food sources which are low in saturated fat/cholesterol
such as low-fat milk/their products (yoghurt, curd, paneer), egg white, lean meats
(marine foods, chicken), pulses and legumes should be included in the diet. High fat-
protein foods such as red meats (cow, buffalo, pork etc.), egg yolk and processed
cheese should be avoided. Incorporating sprouted pulses in sandwiches, rotis, salads,
soup, pulao are good options for increasing the protein content of meals.
Fat: The diet should not provide more than 20% of the total energy from fat. The
total fat intake comprises of both visible and invisible fat (refer to Box 4.2) Conscious
efforts must be made by the patient to restrict the intake of cooking fat, as well as,
that present inherently in foods. Food sources of invisible fat (particularly saturated
fat) such as red meats, egg yolks, nuts, oilseeds, margarine, certain bread spreads,
bakery products should be completely restricted. The visible fat intake can be
curtailed by avoiding fried food, using non-stick cookware/ micro-wave or cooking
food by roasting, grilling and baking (dry heat). Butter, cream, pure ghee should be
avoided and vegetable oils rich in MUFA’s/PUFA’s (low in SFA’s) such as olive,
safflower, corn, sunflower should be used in limited amounts. The dietary cholesterol
intake should be kept below 300 mg/dl if the patient is not suffering from any heart
disease. However, hyperlipidemic obese patients may benefit by lowering the dietary
cholesterol intake to < 200 mg/day.
58
Nutritional Care of
Box 4.2 Visible and Invisible Fat Weight Management
Minerals and Vitamins: A weight reduction diet, if well planned, can provide adequate
amount of all vitamins and minerals. Obese individuals should be encouraged to consume
liberal amounts of raw non-starch vegetables and good amounts of low-calorie fruits
preferably with their edible peels (raddish, cucumber, severely restricted in fat several
months as in case of Grade III obesity; the patient may be at risk of developing
deficiencies of fat-soluble vitamins. Thus, care must be taken to ensure adequate
intake of vitamin E (green leafy vegetables, almonds etc.), -carotene ( yellow and
orange coloured fruits/vegetables) and vitamin D (sunlight, oils fortified with vitamin
A/D). Incorporating fermented foods and sprouted pulses/legumes can help in improving
the bioavailability of several nutrients.
Exercise and Lifestyle: Physical activity and physical fitness are important
determinants of morbidity and mortality related to over-weight/obesity. Exercise
(particularly a combination of aerobic and resistance trainings) should be an integral
part of the weight reduction regime.

METABOLIC DISEASES
Structure
5.1 Introduction
5.1 INTRODUCTION
In this practical unit, we shall first quickly recapitulate about the various characteristic
features and clinical symptoms of diabetes and gout about which you have already
studied in the theory course (MFN-005) in Unit 12 and 13. Thereafter, we shall learn
about the various practical aspects/principles of dietary management which are
imperative for the successful treatment/management of the above mentioned diseases.
These will be followed by practice exercises that would help you in learning about the
step-by-step process required for individualized planning diets as per the requirements
of the patients.
Objectives
You may have already studied about these diseases in the Unit 12 and 13 of theory
course on Clinical and Therapeutic Nutrition (MFN-005). However, mentioned below
is a brief description/review regarding diabetes mellitus and gout which is the focus of
this practical.
77
Clinical and A) Diabetes Mellitus
Therapeutic Nutrition
Diabetes mellitus is a chronic metabolic condition characterized by derangements in
the metabolism of glucose, as well as, abnormalities in the metabolism of fat, protein
and other substances.
As has been mentioned in the theory course, in Unit 12, diabetes is a metabolic
disorder characterized by the following symptoms: Glycosuria, Hyperglycemia,
Polyuria/nocturia, Polydipsia, Dehydration and Ketoacidosis.
l Dietary modifications
l Life-style management
B) Gout
Elevated serum uric acid (>7.5 mg/dl) levels. The risk of developing uric acid
renal stones increases by 50% when the serum urate levels reach above 13 mg/
dl.
Erythrocyte Sedimentation Rate and White cell count rise during an acute attach.
The metatorsopharyngeal joint of the great toe is the most susceptible joint
(‘podagra’), although others, especially those of the feet, ankles and knees are
commonly affected.
The involved joints are swollen and exquisitely tender. The overlying skin is
tense, warm, dusky red and painful to touch.
Tophi may be found in the external ears, hands, feet, olecranon and prepatellar
bursas. Their size may be as small as that of a pin head to as big as a golf ball.
Tophus a characteristic lesion of gout, is a nodular deposit of monosodium urate
mono hydrate crystals, with an associated foreign body reaction.
Material aspirated from a tophus shows typical crystals of sodium urate which is
used as a laboratory test to confirm diagnosis.
The treatment schedule of gout generally includes taking care of the acute phase first
followed by management of hyperuricemia.
a) Acute Phase:
Complete bed rest for at least the first 24 hours after an acute attack.
78 Early ambulation may precipitate recurrences.
Drugs generally prescribed include: Non- steroidal, anti-inflammatory drugs Planning Diets for
Metabolic Diseases
(NSAID’S), Colchicine, Cortico-steroids and Analgesics.
Diet modifications
Maintaining serum uric acid levels below 5 mg/dl (diet and drugs)
With this basic review, let us now learn about the objectives and principle of dietary
management for diabetes viz. non-insulin and insulin dependent diabetes mellitus, and
gout.
The dietary management of diabetes as is being practiced today is based on the following
objectives:
The diabetic nutrition plan should therefore be individualized and must focus not only
on the diabetic state but also on overall health and well-being of the patient. Let us
quickly recapitulate the basis of assessing the requirements of the patients.
Energy : The requirement for energy should be computed on the basis of age, gender,
type of diabetes, drugs/insulin and activity pattern, as well as, pathophysiological stress
(if any). For adult diabetics the energy requirements are generally based on the
achievement and maintenance of ideal body weight. In case of juvenile diabetics, we
also need to take care for providing adequate calories/other nutrients to facilitate
normal physiological growth and development. Thus, for adult diabetics (generally
NIDDM patients) the ideal body weight can be calculated on the basis of height: 79
Clinical and IBW (Men) = 48 kg for first 5 feet + 2.7 kg for each additional inch ( + 10% for build)
Therapeutic Nutrition
IBW (Women) = 45.5 kg for first 5 feet + 2.3 kg for each additional inch ( +10% for
build)
The value of IBW can then be utilized for computing the energy requirements of
normal, under/over weight patients as given in Table 5.1.
Sedentary 20-25 30 35
Moderate 30 35 40
Heavy 35 40 45-50
Protein: The protein intake should be kept to normal or slightly increased intake
because in poorly regulated cases of diabetes; large quantities of nitrogen get
excreted in the urine. Secondly, since proteins have a longer gastrointestinal transit
time; the post-prandial increase in blood glucose would be slower and tapered as
compared to after the consumption of meals low in proteins. Plant origin protein
food sources (legumes, whole, pulses and their products) being high in fibre but low
in saturated fat/cholesterol should be preferred over animal origin protein food
sources particularly in case of adult/overweight/hypercholesterolemic diabetics.
Thus, we can include adequate amounts of whole pulses (horsegram, Bengal gram,
green gram whole, rajmah, cowpea), legumes, beans, skimmed milk, cottage cheese
(paneer)/curd/yoghurt made from skimmed milk, tofu, soya milk, lean meat such as
chicken, egg white, fish and other marine foods may be included in the diet.
Cereals/cereal flour can be substituted with whole Bengal flour, soya flour, besan
to increase the protein and fibre content of chappatis and breads. Similarly, sprouts
can be added to salads, sandwiches, chelas, patties, idlis etc.
Carbohydrates: Both the quantity and quality of carbohydrates play a crucial role
in the management of diabetes. The carbohydrate allowance may vary from 55%
to 60% depending upon the severity of hyperglycemia, weight, type of drugs/
insulin, activity pattern, age and gender of the patient. While a carbohydrate intake
of <100gm may cause ketosis (hypoglycemia); an intake of >300 gm may elicit a
hyperglycemic shock. The National Diabetes Associations of several countries
recommend a nutrition plan that provides generous amounts of complex carbohydrates
and fibre as it lowers the glycemic index (glycemic response) of a particular food/
meal.
The total carbohydrate should be evenly distributed throughout the day depending
upon the drugs/insulin being given to the patient. For instance, NIDDM patients
on hypoglycemic drugs need to consume carbohydrate in equal amounts for breakfast,
lunch and dinner. Patients on a combination of intermediate and long acting insulin
need to take some carbohydrate early morning, as well as, after breakfast apart
from that in breakfast, evening, lunch and dinner. Patients on short acting insulin
must consume meals within half-an-hour of administering the injection.
Diets providing liberal amounts of fibre and complex carbohydrates have been
highly recommended for diabetics. Most of the patients benefit from diets providing
25 gm dietary fibre for each 1,000 Kcals consumed. The benefits of incorporating
80 fibre rich foods in the diet have been enlisted in Box 5.1.
Planning Diets for
Box 5.1 Advantages of High Fibre Intake for Diabetics Metabolic Diseases
Source: Anderson JW, Nutrition, management in Diabetic Mellitus in: Modern Nutrition in Health
and Disease Yong and Shills.
High fibre foods also have a low glycemic index. Look up sub-section 12.3.3 in
Unit 12 in the theory (MFN-005) course to recapitulate your understanding about
the glycemic index concept. Diabetics should be recommended to preferably
consume whole cereal grains (wheat, jowar, bajra, ragi), whole pulses (soyabean,
horsegram, whole Bengal gram, rajmah, cowpea, whole moong, whole urad, sprouts),
high fibre vegetables (cabbage, lotus-stem, drumstricks, beans etc.) and fruits
(guava, pineapple, apple, peaches, avocado etc.) with a lower glycemic index.
Susbtitution of cereals with pulses/vegetables (chappati prepared by using whole
wheat flour + soyaflour/ whole Bengal gram flour/ besan methi/ spinach or vegetable
idli/uttpam, pulao with sprouts etc.) can also help in lowering the glycemic response
to food. Preparations like roasted channa chappaties, sprouted dal are more
suitable than boiled rice, khichri, washed dals and fruit juices. Similarly, raw
vegetables (salads) will have a lower glycemic response as compared to their
cooked counterparts. Sipping 50 grams glucose slowly over several hours shall
produce a smaller increase in blood glucose than would a rapid intake. Box 5.2
gives a list of food stuffs with their respective glycemic index.

Animal foods such as red meats (goat, buffalo, pork etc.) egg yolk, whole milk and
whole milk products you may recall are rich sources of cholesterol, as well as, saturated
fats. Plant foods do not contain cholesterol as such but certain plant foods such as
nuts and oilseeds being rich in saturated fatty acids can result in the elevation of
serum lipids among obese and other ‘at risk’ individuals. These should therefore be
avoided. Lean meats (marine food, chicken), curds, yoghurt and cheese (paneer)
made from skimmed milk are low in cholesterol and can be taken in recommended
amounts.
Life Style and Exercise: An active scheduled life style involving regular and sustained
exercise(s) can help in improving glycemic control. An active life style and regular
exercise helps in:
As a dietitian, we may need to check the exercise schedule of our patients carefully.
Depending on the type, duration/severity of exercise changes may need to be made in
the amount/type/distribution of carbohydrates. For instance, a 20 minutes walk may
not need any additional carbohydrate unless it is immediately prior to a scheduled
meal. However, a short session of vigorous exercise (badminton, volleyball, football)
may necessitate 10-20 gram carbohydrate beforehand. Similarly, rapidly absorbed
carbohydrate (glucose drink/tablets, small chocolate bar) may be necessary before a
burst of intense activity, whereas, more slowly absorbed carbohydrates (sandwich,
biscuits) may be appropriate for sustained exercises. Dietitians must effectively counsel
school going children and adolescents to take their meals/snack before their games
period/exercise.
Having discussed the various aspects of dietary management for diabetics in association
with lifestyle and drugs, let us now translate the above information in terms of practical
tips that can be utilized during patient counseling. As we all know that effective
counseling can help the patient in adhering to self-discipline which plays a crucial role
in maintaining a good glycemic control and is critical towards the prognosis of diabetes
(delaying the onset/severity of complications).
83
Clinical and Here are a few useful tips. You may add or modify these points according to the
Therapeutic Nutrition individual requirements of the patient.
Handy Tips Related to Diet for the Diabetics
Whole grain cereals (wheat, jowar, bajra, ragi), whole grain cereal flours, sprouted
cereals, bread prepared by using whole wheat flour, cracked wheat, wheat bran
should be preferred over low fibre cereals such as rice, chirwa, suji, refined
wheat flour (maida), arrowroot, sago and their products such as vermicelli, pastas,
bread/biscuits/bakery products/kulchas etc.
Foods rich in SFA’s i.e. butter, cream, margarine, pure ghee, egg yolk and animal
fat should be completely avoided. Emphasis should be laid on the use of vegetable
oils rich in PUFA’s, MUFA’s such as olive, safflower, rice bran, corn, cottonseed
oil etc.
It is a good option to keep changing oils used for cooking. For instance, olive,
safflower, corn and rice-bran oil may be used interchangeably over a period of 6
months.
Food should preferably be cooked by dry heat methods (roasting, sautéing, grilling,
baking, micro-wave). Moist heat methods (boiling, simmering) should be avoided
as far as possible. Non-stick cookware helps in reducing the amount of fat used
for cooking and can be helpful particularly for obese and/or hypercholesterolemic
diabetics.
Roasted channas/soyabean/Bengal gram dal, soya and wheat puffs mixed with
oat/wheat flakes are good ready-to-eat snacks.
Whole pulses (soyabean, cowpea, rajmah, whole moong, whole urad, whole Bengal
gram, horse gram), legumes, sprouts and whole pulse flour (whole Bengal gram
flour, soya flour, whole moong flours as a substitute for cereals) should be preferred
over de-husked washed pulses (“dhuli dal”) such as arhar, washed moong/masoor/
urad.
Tubers and starchy vegetables such as potato, yam, colocasia sweet potato should
be avoided.
Skimmed/low-fat and skim milk products such as curd, yoghurt, paneer should
be preferred particularly by adult and obese diabetics.
Lean meats such as poultry (chicken, egg white), fish should be preferred over
red meals (goat, buffalo, cow, pork) and egg yolk.
High fibre and/ or low calorie vegetables should be preferred such as amla,
cabbage, drumstick, raddish, cucumber, lotus-stem, beans, ladyfinger, tinda, bitter
gourd (karela) and leafy vegetables (amaranth, lettuce, fenugreek, mustard) should
be consumed liberally.
High fibre and/or low calorie fruits such as apple, guava, pineapple, raspberries,
musk melon, water melon, pear, bael should be preferred over mango, banana,
grapes etc.
It is advisable to consume plenty of raw vegetables especially in the form of
salads (with sprouted cereals/pulses) before meals and along with their edible
84 peels wherever feasible.
Raw, whole fruits (1-2 servings per day) should preferably be consumed with Planning Diets for
Metabolic Diseases
their edible peels.
Idlis, poha, dalia, uttapam, dhokla prepared by incorporating sprouted pulses/
legumes and plenty of vegetables are nutritious evening snacks.
If the patient is hypertensive; restrictions may be required in the use of cooking/
table salt. Pickles, chutneys, preserves, baked items, canned food and salted
snacks should also be avoided.
Lemon water, zeera pani, kanji, lemon tea, tea, butter milk (lassi) are better
options over fruit juices, fruit drinks and soft-drinks (colas etc.).
The fibre intake can be increased by using commercially available sources of
fibre such as guar-gum (obtained from seeds of cluster bean), Xanthum gum,
neem bark/leaves powder, husk/bran of cereals/pulses and edible peels of raw
fruits/vegetables.
Handy Tips Related to Meal Pattern
As a thumb rule, diabetics should avoid both feasting and fasting.
A fixed meal pattern should be followed and meals should be consumed within
½ to 1 hour of taking hypoglycemic drugs/ short-acting insulin (refer to Box 5.3
for more information regarding food intake with respect to insulin type).

1) First calculate the ideal body weight (IBW) of the patient using the formula given herewith.
48 kg for first 5 feet + 2.7 kg for each additional inch
i.e. 48 kg + 2.7 7 = ……… kg (IBW)
The value obtained for IBW can then be employed for calculating the energy requirements of
Mr. Khanna (to help him in reducing his excess body weight). Energy requirements for an
adult sedentary man can be calculated as follows:
20 - 25 Kcal/ kg IBW/ day

6.1 Introduction
6.2 Peptic Ulcers
6.2.1 Pathophysiology
6.2.2 Principles of Dietary Management
6.1 INTRODUCTION
Disorders of the gastrointestinal tract encompass a wide range of diseases which may
be as mild and ubiquitous in prevalence such as dyspepsia, gastritis, nausea, vomitting,
diarrhoea to not so frequent in occurrence such as carcinomas, inflammatory bowel
disorders, lactose intolerance, gluten enteropathy etc. The dietary management of
some of the disorders can be as simple as modification in consistency to as complex
as elimination of certain nutrient or providing elemental/ hydrolyzed formulas. Diseases
such as peptic ulcers can be life threatening whereas; diseases such as ulcerative
colitis can progress towards the development of carcinomas (requiring surgery). In
this unit we shall learn and practice the dietary management of peptic ulcers and
ulcerative colitis. Let us first begin with their pathophysiology and the impact of the
disease condition on the nutritional status of the patient. Before we begin, we suggest
you look up Unit 6 in the Applied Physiology Course (MFN-001) to revise the physiology
of the gastrointestinal system. Also review Unit 14 in the Clinical and Therapeutic
Nutrition Course (MFN-005) to recapitulate the causes, important signs and symptoms
and the dietary management of peptic ulcer and ulcerative colitis.
Objectives
describe the principles of dietary management for peptic ulcer and ulcerative
colitis, and lactose intolerance, and
plan diets for individuals suffering from these disorders i.e. peptic ulcer, ulcerative
colitis and lactose intolerance.

Nutritional Management
6.2 PEPTIC ULCERS of Gastrointestinal
Disor ders
Peptic ulcer, you may be aware by now, is any localized erosion or a break in the
gastric/duodenal mucosa that arises when the normal mucosal defensive factors are
impaired or are overwhelmed by aggressive luminal factors such as acid and pepsin.
Let us first review the pathophysiology of peptic ulcers followed by the principles of
dietary management.
6.2.1 Pathophysiology
Ulcers may develop in the stomach/jejunum (gastric ulcers) or /and in the duodenum
(duodenal ulcers). Let us review these conditions.
Gastric Ulcers occur most frequently along the lesser curvature of the stomach.
Look up Figure 6.8 in Unit 6 in the Applied Physiology Course (MFN-001) which
illustrates the stomach. Gastric ulcers are associated with gastritis, inflammatory
involvement of the oxyntic (acid producing) cells and atrophy of the acid and pepsin-
producing cells with advancing age. Morbidity and mortality are higher among gastric
ulcers due to haemorrhages as compared to in duodenal ulcers.
Duodenal Ulcers generally occur within the first few centimeters of the duodenal
bulb, in an area immediately below the pylorus. They are characterized by increased
acid secretion particularly nocturnal acid secretion and decreased bicarbonate secretion.
The major causes of ulcers are:
Chronic infection of helicobacter pylori
Consumption of hypersecretory agents such as non-steroidal anti-inflammatory
drugs
Alcohol, tobacco consumption and cigarette smoking
Tea, coffee, spices
Physical/emotional stress
The sign and symptoms which may adversely affect the nutritional status of patients
suffering from ulcers include:
Epigastric pain which is frequently described as gnawing, dull, aching or “hunger-
like”
Nocturnal pain
Nausea, anorexia, dyspepsia
Gastrointestinal haemorrhage (melena)
Weight loss
Symptoms of ulcers are characterized by rhythmicity and periodicity. Approximately
half of the patients report relief of pain with food or antacids (especially duodenal
ulcers) and a recurrence of pain 2-4 hours later. This is an important factor which
must be taken into consideration while deciding the meal timings and frequency for
the patient.
The treatment of the problem is based on:
Alleviation of the underlying cause,
Drugs (anti secreatory, enhance mucosal defense),
Providing relief from symptoms/complications, and
Dietary management to promote a good nutritional status.
In the subsequent sub-section we shall learn about the essentials of dietary management
during the various stages of peptic ulcers and also for the successful management of
complications that may arise as a result of gastric surgery performed for the treatment
of complicated cases of peptic ulcers. 107
Clinical and 6.2.2 Principles of Dietary Management
Therapeutic Nutrition
The dietary management regime of peptic ulcers has witnessed several changes.
The most popular conservative diet therapy was the Sippy’s diet wherein 6 small 1-2
hourly feedings comprising of mainly cream and milk were given to the patient.
However, this resulted in the elicitation of nutritional disorders such as
hypercholesterolemia, scurvy, alkalosis and tetany (Milk-Alkali Syndrome) to name a
few. At present we are following a more liberal approach which was initiated by
Meulen Gracht. We shall now discuss in detail the various aspects of dietary
management for peptic ulcers. However, let us first identify the objectives of nutritional
care for a peptic ulcer patient.
Objectives
The objectives of nutritional care for a peptic ulcer patient include:
to prevent further erosion and promote healing of the mucosal lining,
to maintain an optimum pH in the alimentary tract,
to coordinate acid secretion with food intake, and
to correct nutritional deficiencies and promote a good nutritional status.
In light of the above mentioned objectives we shall discuss the requirements for various
nutrients. We will first discuss the energy needs for the patient.
Energy : The requirements for energy should be based upon the existing health status
of the patient. Majority of the patients are malnourished due to abdominal pain
associated with food intake and to poor digestion/absorption. Thus, if the patient is
ambulatory; it is recommended to increase the energy intake by about 10%. However,
in case of hospitalized (bed-rest) patients; normal energy intake (as per RDI) would
suffice for the extra needs. Providing 35 Kcal/kg IBW to promote weight gain may
not be feasible during the active phase. This is generally recommended during the
recovery stage (latent).
Let us now learn how to provide the recommended energy through various
macronutrients viz. proteins, fats and carbohydrates.
Proteins: The protein intake should be increased by about 25% to 50% above the
RDI. Proteins should be increased to:
provide buffering effect – since proteins have a longer intestinal transit time than
carbohydrates.
High biological value proteins, which are at the same time easy to digest, should be
provided. While eggs and washed pulses can be included liberally; meat and milk
should be given in moderation (since calcium present in milk and meat stimulate acid
secretion). Whole pulses and legumes, if given, should be in a soft cooked/ blended or
pureed form (boiled, fermented, sprouted and steamed etc.). Protein supplements
such as complan, casilan, Pro Mode, threptin biscuits may be included in the menus.
Sprouts/dal khichdi, uttapam, idly, egg nog, soufflé, baked custard, puddings, poached/
boiled egg, porridge, baked/steamed chicken/fish etc. (small serving) can be given to
patient.
Carbohydrates: Nearly 60% of the total energy should be provided from carbohydrates
to ensure maintenance of body weight and to ensure spairing of proteins for tissue
synthesis. However, emphasis should be laid on foods rich in mono/disaccharides
108
and/or starches. The intake of dietary fibre, particularly insoluble fibre (husk, bran, Nutritional Management
of Gastrointestinal
peels etc.) should be avoided to prevent irritation to the ulcers. For the same reason Disor ders
food should be well cooked and blended/pureed to make it mechanically bland. Fruits
should be steamed before serving. Care should be taken to exclude harsh sources of
fibre such as seeds of citrus fruits and vegetables. Tomatoes if used as soups/purees
can be tolerated in moderation (seeds get crushed). For the same reason wheat flour
should be sifted through a fine mesh and whole cereal (bajra, jowar, ragi etc.) flours
should not be included in the diet. Among the cereals rice, semolina, refined flour,
sago, pasta, arrowroot/potato powder would be good options.
Fat : Nearly 20-25% of the total energy should be provided from fat because fat in
any form delays gastric emptying, suppresses gastric acid secretion and motility. The
quality of fat however should be selected according to the age and present health
status of the patients. It is generally recommended to lay stress on emulsified fats
and those rich in medium chain triglycerides (olive oil, coconut oil). Foodstuffs rich in
emulsified fats (eggs, whole milk, cream, butter) are generally good sources of saturated
fatty acids etc. Thus, middle aged ulcer patients, especially those at risk of developing
coronary artery diseases, should lay greater emphasis on MCT’s or vegetable oils
rich in MUFA’s/PUFA’s rather than emulsified fats.
Besides the nutrient requirements discussed above, let us also review a few other
considerations to be kept in mind while planning diets for ulcer patients.
General Considerations
Small, easy to digest meals should be given to the patient at very short intervals.
An eight meal pattern is generally recommended during the acute phase while
during recovery/latent phases, the patient should preferably adhere to a 5-6 meal
pattern.
Foods consumed should not stimulate gastric acid secretion. Thus, stimulating
beverages such as tea, coffee, cocoa, carbonated drinks, spices, condiments,
should be avoided. Patients may be given small servings of decaffeinated
tea/coffee. Studies have shown that small amounts of condiments in the
form of powder (cardamom) do not promote/aggravate acid secretion. Red
and black pepper have been associated with mucosal damage and increased
gastric acid secretion.
6.3.1 Pathophysiology
Look up Figure 6.16 in Unit 6 in the Applied Physiology Course (MFN-001) to
recapitulate the structure of the colon. Yes, colon begins at the caecum and terminates
at the rectum and anal canal. Approximately 50% of the patients have disease confined
to the recto-sigmoid region; 30% extend to the splenic flexure (left-sides colitis); a
less than 20% extend more proximally (extensive colitis). It occurs most frequently
among individuals in the age group of 15 to 50 years; with a secondary peak at 50-60
years of age. In most patients, the disease is characterized by period of symptomatic
flare-ups and remissions.
The treatment and management of this inflammatory bowel disease is individualistic
and dependent upon the characteristic features during the acute and remissions phases.
The major signs and symptoms include:
Diarrhoea with blood
Rectal bleeding/inflammation/tenderness
Abdominal pain/cramps
Faecal urgency
Hypotension
Anaemia (usually severe)
Hypoalbuminemia
Mild fever
The treatment of ulcerative colitis is enumerated next.
Treatment
Treatment of ulcerative colitis is targeted towards meeting the objectives of terminating
an acute symptomatic attach and preventing recurrence. The most frequently adopted
regime includes:
Dietary modifications for both acute and remission phase
Drugs (anti diarrhoeal/anti inflammatory and immunosuppressive agents)
110 Surgery
In the subsequent section, we shall learn about the dietary management of Nutritional Management
of Gastrointestinal
patient suffering from ulcerative colitis during the phases of acute attack, as well as, Disor ders
remission.
food aversions, anxiety and fear of eating related to experiences with abdominal
pain, bloating, vomitting and diarrhoea,
In view of the above nutritional implications, we shall now discuss the nutrient
requirements and dietary modifications for patients during acute and remission phases
of ulcerative colitis. But first let us review the objectives of nutritional care for ulcerative
colitis patient.
Objectives
The objectives of nutritional care for ulcerative colitis patient include; to help in man:
to help in managing/alleviating symptoms such as diarrhoea
to maintain a positive nitrogen balance
to help in replenishing the depleted reserves of vitamins, minerals and electrolytes
to prolong the phase of remission and hence delay the frequency/severity of
acute attacks
to promote the management of clinical complications such as anaemia
to prepare the patient for surgery (if required)
to maintain a good nutritional status.
Energy: Patients are generally in a negative energy balance due to poor appetite and
diarrhoea. Majority of the patients are ambulatory and tend to loose some weight due
to repeated episodes of acute attack. During the acute phase, the patient is usually on
a low energy, liquid diet (parenteral or enteral nutrition). Whereas, during the remission
phase, the patient should be advised to consume energy as per the RDI or that sufficient
to maintain an ideal body weight. Thus, the energy intake may vary from 25-35 Kcal/
kg IBW.
Remission Phase
The dietary treatment is based upon the determination of lactase activity as the treatment
depends on the level of activity of lactase enzyme. Let us focus on the nutritional
management next.
Nutritional Management
Diagnostic tests are available that can give information about the level of lactase
activity of the lactase enzyme. Depending on the level of activity (very low level,
moderate level) the dietary treatment could be planned. Let us see how.
Very low level of lactase activity: At very low level of lactase activity all milk
products must be eliminated substitutes of milk like soya milk, groundnut milk
and their preparations could be given. Enzyme such as Lactaid and Maxilact are
available in the market. Addition of these in the milk or milk products could
digest 90% of lactose in milk and thus minimize the symptoms of lactose
intolerance.
Lactose is present in dairy products such as milk, cheese, yoghurt, ice cream etc.
Hidden sources of lactose may include bread, candy, cookies, biscuits, sauces, gravies,
soups etc. Hence, depending upon the amount of lactose an individual can handle,
major or minor dietary restrictions may be imposed.
Because dairy products are restricted or avoided, which are a major source of calcium,
which children need to develop strong bones, it is important to serve calcium-rich
foods to make up for the loss. Tofu, broccoli, pulses (Bengal gram whole, horse gram,
rajmah), nuts and oilseeds, green leafy vegetables (particularly amaranth, fenugreek),
fish and sea foods are excellent sources of calcium.
To help you remember the important aspects, some handy tips are enumerated
114 herewith.
Remember : Nutritional Management
of Gastrointestinal
Disor ders
Identify the level of lactase activities (diagnostic tests)
Depending on the enzyme activity eliminate milk and milk products
Substitute milk and milk products by giving soya sources like tofu, soymilk, soy
curd and groundnut milk
Give a well balanced diet
If moderate lactase activity is present small amounts of lactose (within individuals
tolerance level) can be given several times a day
Small amounts in moderate lactose activity can be tolerated if taken with other
foods e.g. after a meal or a snack
Curds is better tolerated than milk
In case low lactose foods available commercially like ice cream, cottage cheese
try them
Lactose enzymes are available these should be added in the milk
Deficiency of lactose and calcium could be supplemented by giving other foods
rich in the same
With this we end our study of gastrointestinal disorders.
There are three activities included in this practical. We shall practice and learn how
to plan diets during the peptic ulcer and during the acute and remission phases of
ulcerative colitis in the first two activities. The third activity deals with diet planning
for lactose intolerance. Before you move on to these activities, do check your
understanding on this topic by answering the review exercises included next. These
are self-check exercises.

Case Study : Kapila is a 37 year old news reporter who was admitted two weeks
back complaining of constant radiating pain in the epigastrium. She
had been diagnosed to be suffering from ulcers about a year back.
Of late she had been complaining of nocturnal pain. Laboratory
examinations have indicated anaemia, mild leukocytosis and general
malnutrition. Kapila’s height is 5’4” and her usual weight has been
53 kgs. At present she weighs 49 kgs. Endoscopy and other imaging
tests have indicated perforation of ulcers and she has been
diagonised to be suffering from gastric ulcers. Kapila was initially
put on enteral tube feeds and is presently being given a high energy,
high protein bland soft diet. She has also been prescribed drug
therapy. Her condition is being monitored for subsequent gastro-
intestinal bleeding/perforations. At present her condition is stable
and she is on stage II diet.
Kapila is suffering from an advanced stage of peptic ulcers. At present her condition
needs to be managed carefully. Both the consistency and composition of diet need to
such so as to prevent further damage to the mucosal lining and at the same time
promote healing. Keeping this in mind, proceed towards planning a diet for Kapila,
following the instructions given in this activity.

MANAGEMENT IN LIVER,
GALL BLADDER AND
PANCREATIC DISEASES
Structure
7.1 Introduction
7.1 INTRODUCTION
In the previous practical we learnt about the dietary management of the diseases
associated with the gastrointestinal tract. In this unit we will discuss about the diseases
of the liver, gall bladder and pancreas. Hepatitis, cirrhosis, cholecystitis/cholelithiasis
and pancreatitis are the major diseases which will be discussed in this practical. We
will begin with a brief on the pathophysiology (impact on nutritional status), characteristic
symptoms of the above mentioned diseases and thereafter focus on the various aspects
of dietary management. The activities included in this practical will help us to understand
and learn about the applied aspects related to working out a day’s diet for each disease.
Before you begin, we suggest you look up the concepts related to the pathophysiology
and principles of diet planning related to these disease already covered in the theory
course (MFN-005) in Unit 15.
Objectives
describe the various aspects of dietary management of the liver, gall bladder and
pancreas diseases, and
Nutritional support plays a major role in the clinical management of patients with liver,
pancreas and biliary disease(s). It has widely been recognized that malnutrition
adversely affects outcome in both chronic and acute form of diseases of the liver, gall
bladder and/or arise in patients with chronic forms of hepatobiliary and pancreatic
disorders. Thus, the objectives of the nutritional support shall be to provide nutrient in
the correct quantity and form, to restore and maintain nutritional status, correct specific
deficiencies, treat clinical symptoms and promote regeneration of the lost tissues.
Wide spectrums of diseases are associated with the insufficiency and/or dysfunction
of liver, gall bladder and pancreas and the most important ones include:
Liver Gall Bladder Pancreas
Acute viral hepatitis Cholecystitis Acute pancreatitis
Liver cirrhosis Cholelithiasis Chronic pancreatitis
Hepatic Encephalopathy Cystic fibrosis
or Hepatic Coma Tumors
Pancreatic abscesses
Fistulas
Let us briefly recapitulate the pathophysiology, symptoms and dietary management
related to these disorders.
While the above mentioned symptoms may subside in 2-8 weeks; complete recovery
takes a long-time. Majority of the symptoms associated with the term ‘jaundice’
adversely affect the food intake. Further, patient may also experience low grade
fever thereby increasing the nutritional demands on the body. Efficient treatment and
management of hepatitis is a must to prevent its progression towards cirrhosis/ hepatic
encephalopathy etc. Let us then study about the treatment of hepatitis.
Treatment
The treatment focuses on:
Dietary management to maintain a good nutritional status.
Bed rest or avoidance of strenuous physical activity.
Drugs, if required (non-metabolism).
Avoidance of hepatotoxic agents particularly alcohol.
Irrespective of the cause of hepatitis, regeneration of the lost liver cells is essential to
promote recovery and hence promote proper functioning of the organ. Relapse of
hepatitis or progression of acute hepatitis to a chronic form/cirrhosis occurs many-at-
times due to impaired nutritional status. Liver being a store house for several nutrients
(particularly vitamins/minerals), the nutritional reserves may get depleted during
hepatitis. Thus, the major objectives of dietary management include:
We will now discuss the nutrient modifications necessary to promote quick recovery
and prevent further degeneration of hepatic cells. Let us start with the calorie
requirement.
Energy : Majority of the patients experience weight loss and are malnourished due to
reduced food intake. Low grade fever is generally present during viral hepatitis which
also imposes increased demands for calories due to an increase in basal metabolic
rate. Adequate energy intake is also essential to ensure proper utilization of proteins.
The energy requirements may increase by 15 to 30% depending upon the existing
nutritional status. However, the energy intake should be increased gradually. An
aggressive increase in energy results in aggravating gastrointestinal disturbance. Due
to severity of jaundice during the early stages it may not be feasible to provide more
than 1200 Kcal per day. However, during the convalescence phase, adequate intake
of energy is feasible and a must to ensure complete recovery. If the patient is grossly
underweight, the energy intake may be calculated as 35 Kcal/kg IBW to ensure weight
gain and replenishment of glycogen reserves.
136
Protein: The protein intake should be increased by 50% to 100% in mild and moderate Nutr itio nal
Management in Liver,
cases of hepatitis i.e. the patient should be given 1.5 to 2.0 gm protein per kg IBW per Gall Bladder and
day. However, if hepatitis is severe and there is risk of developing cirrhosis; the Pancreatic Diseases
protein intake should not exceed 1.0 g/kg IBW/day i.e. the protein should be provided
as per the RDI.
Fat: Fats should not be severely restricted as they can make the food unpalatable.
About 20% of the total calories should be from fat. MCTs are preferred as they are
easily digestible and assimilable (40-50 g). For example, dairy fat cream and butter
are preferable.
Carbohydrates: In mild and moderate cases of hepatitis, carbohydrates should provide
atleast 60% of the total energy. Liberal intake of carbohydrate helps in replenishing
the glycogen reserves and sparing the proteins for tissue regeneration. However, in
severe chronic hepatitis determining the carbohydrate needs is often a challenge
because liver failure reduces glucose production, glucose utilization and there is
preference for the use of lipids and proteins as alternative sources of protein. In such
situations the carbohydrate intake should not exceed 60% of the total energy. Emphasis
should be laid on the inclusion of food rich in monosaccharides, disaccharides and
starches. Dietary fibre intake should be kept minimum. All fibre rich foods should
preferably be avoided and if given, should be in a soft cooked form. Thus, include
good amounts of glucose, dextrose, jaggery, honey, sugar, ago, rice, refined four, pastas,
starchy roots and tubers (potato, yam, colocasiac etc.), high carbohydrate fruits (banana,
mango, sapota, raisins etc.)
Vitamins and Minerals: Impaired liver function and its associated symptoms can
result in increased demand of B-group vitamins, ascorbic acid, vitamin A, K, calcium,
and iron. Among all the nutrient, fat malabsorption is the greatest, therefore -carotene
rich foods should be included in the diet. Include adequate amount of fresh fruits and
vegetables in soft cooked form such as mashed pureed vegetables, vegetable soup,
fruit juice, stewed fruit, fruit jellies, fruit jam, milk shakes, etc.
Fluids: Fluid intake may need to be increased if the patient is suffering from diarrhoea
and/or constipaton. In such cases include good amounts of clear and full-fluids in the
diet such as:
a) Clear fluids: Coconut water, tea/coffee (without milk,) barley water, strained
vegetable/ pulse/ meat soup, strained fit juices, strained carrot/rice kanji etc.
b) Full fluids: Milk based beverages such as tea, coffee, milk shake, soufflé,
baked custard, soup, juice, egg nog, fruit jellies etc.
General Considerations
The other considerations include:
High energy high protein diet should be given to patients suffering from mild to
moderate hepatitis.
During acute hepatitis or if vomitting/diarrhoea is severe, a full fluid or a semi-
soft diet may need to be given.
Small, frequent, easy to digest bland meals should be served to the patient. The
meals should particularly be mechanically and chemically bland.
Since patients experience nausea and anorexia, it is essential to prepare palatable
meals which are attractively served. Inclusion of variety in terms of colour,
texture, taste, flavour and mouth feel is important to motivate the patient
(particularly children) to consume food.
Moist heat methods of cooking such as boiling, pressure cooking, stewing, steaming
should be preferred over dry heat methods such as roasting, grilling etc.
137
Clinical and Sample Menu
Therapeutic Nutrition
We shall now brief ourselves about the dietary management of liver cirrhosis which is
a more serious form of liver diseases and if not treated promptly can result in irreversible
changes leading to death of the patient.
With this, we end our study about the liver diseases. The digestion of food requires a
coordinated functioning of both the liver, as well as, the gall bladder. Diseases of the
liver may be found in association with that of the gall bladder; both or any one of them
can have serious nutritional implications. We shall now proceed towards the
understanding of the major disorders associated with disturbed functioning/altered
physiology of the gall bladder.
Here in this practical we will focus on the dietary modifications necessary for the
successful management of cholelithiasis and/or cholecystitis.
Changing dietary habits and life-style practices are resulting in an increased incidence
of cholelithiasis/cystitis. A high cholesterol intake, lack of dietary fibre, deficiency of
PUFAs and irregular meal timings are predisposable factors associated with
cholelithiasis/cystitis. While cholelithiasis is generally asymptomatic and chronic in
nature, it may be found in association with acute attacks of cholecystitis. Both the
diseases may necessitate altered nutrient intake by the patient. We shall first briefly
discuss about the dietary management of an acute attach of gall bladder diseases and
then proceed towards nutritional modifications during cholelithiasis.
Food Amount
Carbohydrates : Nearly 60% of the total energy should come from carbohydrates.
The frequency of gall bladder diseases has been found to be higher among populations
consuming a low fibre diet thereby indicating a protective role of fibre. Certain
components of fibre modify the composition of bile acid pool and also increase the
amount of chenodeoxycholic acid which enhances the solubility of biliary cholesterol.
However, high fibre foods may at the same time aggravate the problem of abdominal
flatulence. Thus, all high fibre foods should be included in a well cooked form. The
patient should avoid consuming raw vegetables and whole pulses, should preferably
be soaked overnight before cooking. Similarly, sprouts may be sautéed/steamed rather
than consuming them raw.
Fluids : Plenty of fluids need to be given, particularly during the acute phase. This is
particularly important if the patient is suffering from vomitting. In such cases, around
2-3 litres of fluids should be consumed in 24 hrs to prevent dehydration. If vomitting
is severe/persistent; the patient should be given clear fluids at hourly intervals. This
may be followed by a full-fluid diet till the absorption improves. Therefore, give plenty
of clear fluids such as coconut water, rice/carrot kanji, clear soups, clear broths, jelly,
sugar candies, glucose water, lemon/barley/saunf water etc. These may be followed
by full fluids such as milk shakes, tea, coffee, soufflé, fruit juice, vegetable/pulse soup,
custard etc.
Special Considerations
Large and high fat meals should be completely avoided.
Small, frequent low fat meals should be consumed and a fixed meal pattern
should be adopted.
Certain foods such as cauliflower, cabbage, rajmah etc. are potential gas formers
which should be avoided if the patient is experiencing abdominal fullness.
Well cooked, easy to digest meals should be given. Moist heat methods of
cooking such as pressure cooking, steaming, boiling, stewing, broiling should be
preferred.
The fat allowance should be distributed evenly throughout the day to facilitate
drainage of bile from the gall bladder.
Patient must be counseled to prevent starvation/fasts as it increases the risk for
precipitation of bile components in the gall bladder.
Very low calorie/fat diets and starvation therapies should be completely avoided
by such patients.
A sample menu for a low fat diet is presented next for your reference. 143
Clinical and Sample Menu: Low Fat Diet
Therapeutic Nutrition
We shall now brief ourselves with the pathophysiology related to the diseases of the
pancreas.
In view of the fact that acute pancreatitis is generally accompanied by duodenal ileus
and prolonged gastrointestinal dysfunction, as well as, pain which is associated with
the release of pancreatic enzymes and bile; it is advisable to withhold oral and enteral
feeding atleast for the first few days i.e. provide ‘rest’ to the pancreas. The nutritional
support regime generally followed includes:
A sample menu for acute pancreatitis is given herewith for your reference.
Sample Menu:Clear Liquid Diet
Let us now discuss the principles of dietary management during chronic pancratitis/
remission phase after successful management of acute pancreatitis.
Nutrition Support during Chronic Pancreatitis
Maintenance of an adequate nutritional status is the most crucial objective to be met in
view of the recurrent attacks of epigastric pain associated with meals and presence of
nausea, vomitting and/or diarrhoea. Patient usually present symptoms and signs of
145
Clinical and malnutrition such as gradual weight loss, deficits of lean muscle/adipose tissue, visceral
Therapeutic Nutrition protein depletion and impaired immune function. Thus the major objective of nutritional
care is to:
prevent further damage to pancreas,
reduce episodes of pain associated with meals,
correct malnutrition, and
maintain a positive energy and protein balance (if feasible), and
decrease steatorrhoea and other gastrointestinal disturbances.
Thus, the following dietary modifications may be necessary to improve the overall
health status of the patient. We will begin our discussions with energy and then proceed
to macro- and micro-nutrient intake.
Energy : Most of the patients are severely emaciated and in a compromised state of
health. Persistent indigestion and an increase in resting energy expenditure are the
major reasons of weight loss. Ideally, the patient should be given liberal calories to
promote weight gain i.e. ~35 Kcal/kg IBW/day which is practically not possible during
the clear liquid or liquid diet. The patient maybe required to be fed easy to digest
(soft, semi-soft or blenderized meals) food so as to help in minimizing gastric discomfort.
Protein: High amount of protein i.e. 1.0 - 1.2g/kg body weight/ day should be provided
to prevent further nutritional depletion. Enzyme supplementation therapy may be
required to facilitate proper digestion of proteins. Emphasis must be laid on easy to
digest high biological value proteins. However, we should choose those foods which
are at the same time low in their fat content. Thus, red meats, egg yolk, whole milk
and whole milk products should be avoided. Egg white, lean meats, skimmed milk/
skimmed milk products, pulses, legumes, soya milk, tofu should be preferred. Isolated
intact/ hydrolyzed proteins/ protein supplements like whey protein, soy protein, casein,
etc. may be used depending upon the tolerance level of the patient.
Fat : The fat intake should be minimized to as low as feasible. Initially it can be
progressed from no fat to low fat soft- diet. The amount of fat incorporated in the diet
depends upon the severity of steatorrhoea, enzyme replacement therapy and the
degree of malnutrition. The average fat intake should be kept below 15-20% of the
total energy. Further, majority of the visible fat should be in the form of medium chain
triglycerides (MCTs). Natural MCTs are found in milk fat, coconut oil and palm
kernel oil. Low fat foods should be preferred such as fish, chicken, egg white, low fat
milk, low fat milk products (curd, yoghurt, cheese) etc. Fried foods, high fat foods
such as bakery products or dishes prepared by sautéing in liberal amounts of fat,
cream, butter, margarine, bread spreads with fat base, and cooking oils should be
completely restricted. Boiling, low-fat baking, steaming, micro-wave cooking and the
use of non-stick cook-ware are helpful in reducing the fat content of meals. Commercial
MCT oils can easily be incorporated in the meals after cooking especially in soups,
cereal, desserts, vegetable/pulse preparations.
Carbohydrates : Liberal amounts of carbohydrates (>60% of the total energy) should
be provided in the diet to promote weight gain and spare proteins and fat for necessary
metabolic functions. Low fibre, easy to digest carbohydrates should be provided in
the diet. Foods rich in mono/disaccharides and starches should be incorporated in the
diet such as sugar, honey, dextrose, sugarcane juice, date, sugar candies, starchy
roots/tubers (potato, yam, colocasia), arrowroot, sago, rice, refined four, pastas,
semolina, white bread, chirwa (flattened rice), murmura (puffed rice) etc. The intake
of dietary fibre should be minimized in view of gastrointestinal disturbances. Thus,
fruits such as mango, banana, grapes, and dates should be preferred over guava,
pear, pineapple etc.
Vitamins and Minerals : Steatorrhoea may result in impaired absorption of fat-soluble
146 vitamins, as well as, deficiency of calcium and iron. Vitamin B12 deficiency may also
arise due to the deficiency of pancreatic protease. Appropriate pancreatic enzyme Nutr itio nal
Management in Liver,
supplementation therapy can help in alleviating steatorrhoea and facilitating proper Gall Bladder and
digestion and absorption of food/nutrients. A balanced diet containing a variety of Pancreatic Diseases
easy to digest foods can help in alleviating steatorrhoea and facilitating proper digestion
and absorption of food/nutrients.
Fluids: Dehydration may develop during the acute phases of chronic pancreatitis or
when steatorrhoea may get aggravated due to high intake of fat. The fluid intake
should be increased by including clear-fluids/full-fluids such as rice kanji, vegetable
stock/soup, fruit juices, pulse/legume water, egg nog, coconut water, barley water,
soufflé, jelly, syrups etc.
Special Considerations
Small, frequent, low fat easy-to-digest feeds/meals should be given to the patient.
If steatorrhoea is severely aggravated (before/during the initiation of enzyme
replacement therapy), the diet would need to be modified in consistency. The
patient may initially be given full-fluid diet followed by a semi-soft and then a
soft diet.
In view of the impaired gastrointestinal capacity, it is essential to provide well-
cooked meals to the patient. If the need be, blenderized meals may be given
(purees, khichdi etc.)
Fat used for cooking food should be kept to a minimum. Thus, steaming, boiling,
pressure cooking should be preferred. Frying, high fat stewing should be avoided.
Roasted and grilled foods need to be avoided as they are difficult to digest.
Now, we end our study on the dietary management of pancreatitis. Based on this
knowledge, let us now plan diets for the different disease conditions discussed in this
practical. There are three activities included in this practical. These activities will
help you practice what you have learnt so far. Before you begin with the activities, try

Case Study : Mala, a 57 years old women (height 5^3^^ ; weight 64 years) was
admitted to the gastroenterology ward of a hospital when she
complained of sudden onset of severe steady epigastric pain, nausea
and recurrent vomitting. She had been diagnosed to be having small
stones in her gall bladder about a year ago. Imaging tests on admission
have indicated inflammation of the gall bladder, along with
cholelithiasis. Some of the biochemical tests conducted was:
White blood cells: 14, 500 µl
Serum bilirubin: 3.9 mg/dl
Serum aminotransferase: 300 units/ml
She was given drugs to relieve pain and was kept on an NPO regime for 12 hrs.

8.1 INTRODUCTION
In this practical, our focus shall be on planning suitable diets for renal diseases. We
shall review the various renal problems followed by the nutrient requirements during
these conditions and the translation of nutritional requirements into suitable food sources
as per the RDI so as to result in the development of an appropriate diet. Before you
start studying this practical, we suggest you look up Unit 16 in the theory course
Clinical and Therapeutic Nutrition (MFN-005) which presents a detail review on the
various renal disorders covered in this practical.
Objectives
After undertaking this practical you will be able to:
describe the different renal disorders,
discuss the dietary management of the renal disorders, and
plan diets for patients suffering from glomerulonephritis, nephrotic syndrome,
chronic/acute renal failure, end-stage renal disease and nephrolithiasis.

Figure 8.1: Flow diagram for glomerulonephritis
Note: If the patient is suffering from oedema, the present body weight should
not be used to calculate his protein intake. In such cases, the protein intake may
be calculated on the following basis:
The weight documented in his previous medical records (< 6 mths).
Calculate patient’s IBW based upon his height by using the formula:
Men: 48 kg for first 5ft + 2.7 kg for each additional inch
Women: 45.5 kg for first 5ft + 2.3 kg for each additional inch. ( ±10% for small/
large build in both cases)
Since the protein intake is restricted, we must lay emphasis on high biological value or
good quality proteins. Generally, proteins present in animal foods contain a higher
proportion of essential amino acids as compared to those of plant origin. Eggs, milk
and certain milk products (curd, paneer), meat, fish, poultry, whole pulses/legumes
and their products particularly soyabean, soya-milk, tofu, texturized soya protein can
help in improving the essential amino-acid content of the diet. Since cereals (wheat,
wheat products, rice, maize etc) are poor sources of good quality protein; they are
generally substituted by starch rich foods (potato, colocasia, yam, sago, arrowroot
flour etc). Sago khichdi, scrambled egg, halwa, cottage cheese preparations, tofu or
dal stuffed roti, substitution of soya milk for water in the preparation of pulses/legumes/
vegetables/kneading of dough are good options for feeding these patients.
A sample menu for a glomerulonephritis patient is included here for your reference.

Next, let us study about the nephrotic syndrome.
175
Clinical and 8.2.2 Nephrotic Syndrome
Therapeutic Nutrition
Nephrotic syndrome referred to as ‘Nephrosis’, is characterized by impaired nephrons
function and reduced reabsorptive capacity of renal tubules which results in massive
proteinuria and severe oedema. It generally occurs among children. The clinical
symptoms include proteinuria, haematuria, hyperalbuminemia, periphral oedema, ascites,
malnutrition etc. Figure 8.2 illustrates the progressive damage of nephrons a a result
of nephrotic syndrome.
Progressive Damage of Nephrons
Increased amount of proteins filtered through
Glomecular basement membrane
Anaemia Proteinuria
Hypothyroidism Hypoalbuminemia Peripheral oedema
and
Low plasma osmotic ascites
pressure
Reduced plasma volume
The treatment of nephrotic syndrome is based on the cure of the underlying cause,
maintain optimum nutritional status so as to prevent the onset of complications and
handle undernutrition effectively. The dietary requirements for nephrotic syndrome
patients is highligted next.
Energy : Most of the nephrotic syndrome patients are severely malnourished and in a
catabolic state. Adequate amount of energy is required to promote a positive energy
balance so as to promote effective utilization of dietary proteins for the synthesis of
blood proteins and also to prevent subsequent weight loss. The energy intake should
be increased by 10% i.e. around 35-40 Kcal/kg ideal body weight in case of adults and
about 100 Kcal/kg body weight for children.
Protein : Protein intake of 0.8 g/kg ideal body weight plus 1 g/g of proteinuria is
recommended. This helps in maintaining a positive nitrogen balance which helps to
promote hepatic synthesis of albumin and replenish body stores of plasma proteins.
Emphasis should be laid on high biological value proteins such as milk, curd, paneer,
egg whites, lean meats such as poultry/marine foods and whole pulses/legumes.
Although animal proteins contain a higher proportion of essential amino acids as
compared to plant proteins; they are also rich sources of sodium.
A combination of plant and animal protein food sources may be included in the diet.
Besides, we should employ alternative methods of food preparation such as sprouting
and fermentation which help to improve the bio-availability of proteins. Sprouted grain/
legumes (rajmah, whole green gram dal, horse gram, Bengal gram, whole wheat) may
176
be added to any vegetable preparation, paranthas, pulaos, salads, raitas, sandwiches, Planning Diets for
Renal Diseases
cutlets, soups etc. Fermented dishes such as dosa, uttapam, idli, dhokla can also be
included.
Carbohydrates: A high carbohydrate intake (~60 - 65% of total energy is generally
recommended for protein sparying action). A combination of both simple and complex
carbohydrates may be given. Dietary fibre intake may be slightly reduced if the patient
is experiencing gastrointestinal disturbances. Emphasis should always be laid on soluble
fibre and all high fibre foods should preferably be given in a soft cooked form.
Carbohydrate foods help to reduce bulk and facilitate easier/faster digestion which
can help in ensuring an adequate food intake. Since sago, arrowroot, yam, potato are
low in sodium and easy to digest, they should be preferred over jowar, bajra, ragi etc.
(high fibre) which are difficult to assimilate and may cause flatulence. Rice, suji,
maida, wheat flour, breads/pastas (manufactured without using sodium salts) can be
included in the diet.
Fat: Fat intake may remain normal or slightly restricted. Emphasis should be laid on
the inclusion of vegetable oils which are low in saturated fats and are good sources of
poly-unsaturated/mono-unsaturated fatty acids. Animal fats and red meats being high
in saturated fatty acids and cholesterol may be avoided. The diet should not provide
more than 200 mg cholesterol per day if the patient is hypercholesterolemic.
Therefore, we must avoid cream, butter, ghee, margarine, hydrogenated fats
(particularly bakery products), red meats (lamb, pork, bufallo, cow), egg yolk, whole
milk, pistachios, cashewnuts etc. We must also avoid the inclusion of fried/high fat
foods such as mathris, namakparas, kachories, certain biscuits, khaties, creamed
cakes/pastries etc.
Sodium: Although the underlying cause of oedema is proteinuria; restrictions in the
intake of sodium can help in preventing further accumulation of fluids and electrolytes.
Approximately 2-3 g of sodium/day may be recommended. Usually added salt is
prohibited in these patients. Refer to Table 16.2 in Unit 16 and Table 11.6 in Unit 11 in
the theory course which presents the foodstuffs high in sodium. Avoid these foods in
the diet of the nephrotic syndrome patient.
Potassium: Unlike glomerulonephritis, patients suffering from nephrotic syndrome
may suffer from hypokalemia. Potassium deficiency may occur due to prolonged
proteinuria and/or if the patients are being treated with diuretics. Pulses/legumes such
as cowpea, green gram dal, red gram dal, brinjal, cauliflower, carrot, potato, papaya
are fairly good sources of potassium. These may be included in the diet. If potassium
levels get severely depleted, potassium salts such as potassium glutamate may be
used for cooking. This can also help in improving the palatability of meals.
Calcium: In patients suffering from prolonged proteinuria, deficiency of
specialized binding proteins may result in deficiency of calcium. This may result in
bone rarefaction (bone pain and weakness). The blood phosphorus levels should also
be checked regularly to assess the phosphorus status. Therefore, calcium
supplementation along with moderate protein is recommended. Foods rich in calcium
but low in sodium should be selected such as whole pulses/legumes (Bengal gram
whole, black gram whole, green gram whole, rajmah, soyabean), carrots, beans, onion
etc. Skimmed milk and milk products should be used in moderation in accordance
with the sodium and fluid allowance of the patient.
Other Vitamins and Minerals: Most of the patients have a poor nutritional status.
Although anaemia is principally due to loss of blood in urine and an impairment of the
regulatory function of kidneys i.e reduced production of the erythroprotein factor;
majority of the patients also have poor reserves of B-group vitamins such as folic acid,
thiamin and riboflavin. Restrictions on the inclusion of fruits and vegetables make the
diets poor sources of several water - soluble vitamins and minerals. Some food sources
of vitamin C may be included in the diet such as amla, lemons, orange, guava depending
upon the level of sodium restriction as it helps in wound healing. Though vitamin A 177
plays an important role in cell multiplication/differentiation and also in maintaining the
Clinical and integrity of epithelial cells; much stress on the inclusion of vitamin A rich foods/vitamin
Therapeutic Nutrition A supplements is not laid if the nephrotic syndrome is progressing towards renal failure.
To promote calcium absorption and bone calcification, vitamin D may also be provided
in sufficient amounts. Fats and fat rich food sources provide good amount of vitamin
D but need to be restricted due to hypercholesterolemia. Thus, vitamin and mineral
supplements may be required in severe situations.
Fluids: Fluid intake remains normal (~1500 ml/day) as there is no oliguria in
patients suffering from nephrotic syndrome. However, if the condition progresses
towards renal failure, fluid intake may be monitored in accordance with the
urine output.
Some other useful tips for planning diet are also highlighted herewith.
l Since the patients are anorexic but at the same time have increased nutritional
requirements, small nutrient dense meals should be served at frequent intervals.
Thus, a 6-7 meal pattern (early-morning, breakfast, mid-morning, lunch, evening
tea, dinner and bed-time) should be followed.
l Majority of the patients being children, serving the meals attractively with variety
in terms of colour, texture, taste, flavour and mouthfeel can prove to be beneficial
in improving the overall intake of the patient. For example; an orange/strawberry
sugar toffee (sugar hardball/candy) can be crushed and sprinkled over curd/sago
porridge to make it appear attractive.
l Most of the protein rich food sources particularly those of animal origin is also
high in their sodium content. This may restrict their intake. Thus, if the patient is
suffering from severe proteinuria and oedema; protein supplements such as whey
protein, soya protein and casein may be added to the meals to increase the protein
intake. These can be sprinkled over cooked dishes, mixed with flours while
kneading dough or mixed with curd/milk.
All these symptoms and the progression of chronic renal failure also referred to as
‘chronic kidney disease’ have been discussed in the Theory Manual (MFN-005) i n
Unit 16. Let us quickly take an overview of the various stages/symptoms that
take place during the development progression of CRF which are illustrated in

Let us now discuss the various principles of dietary management that are essential for
the effective treatment of chronic renal failure (CRF) which is also referred to as
chronic kidney disease (CKD). While regression of CRF is usually not possible, as a
Dietitian our endeavour should be to prevent the progression and delay the onset/
severity of complications. The various objectives (which must be identified in terms of
their priority) can be outlined as mentioned below.
Objectives
The objectives of dietary management of chronic renal failure are to:
l prevent/control uremia and tissue catabolism,
l maintain fluid and electrolyte balance,
l correct acidosis,
l prevent the onset and/or manage/treat the complications arising due to renal
degeneration,
l prevent further progression of Kidney damage, and
l maintain an optimum nutritional status.
Nutritional modifications are particularly crucial in case of protein, cholesterol, sodium,
potassium, phosphate, calcium and water intake. Before we begin to prepare a diet 179
Clinical and plan, let us brief ourselves regarding the changes in the quantity/quality of foodstuffs
Therapeutic Nutrition for each nutrient. Refer to Table 8.1 for the dietary guidelines.
Table 8.1: Dietary guidelines for CRF
Nutrients Comments
Energy 30-40 Kcal/kg/day for adults and 100-150 Kcal/kg/
day for children.
Carbohydrates 300-400 g/day to avoid endogenous protein
catabolism, gluconeogenesis and subsequently
uremia.
Proteins 0.6-0.8 g/kg/day, with 60-70% as high BV protein.
To reduce N2 load, a mixture of essential amino
acids is recommended.
Sodium 500 mg - 2.0 g/day. Additional Na in case of weight
loss and decreasing urine volume and restriction of
Na in case of oedema and hypertension.
Leaching of foods can lower the sodium and potassium content of foods. Read the
information in Box 8.1 for more information on this topic.
Box 8.1 Leaching of Foods can Lower their Sodium and Potassium
Content.
How can we leach vegetables and certain fruits?
1. Peel the vegetable/fruit, cut into small pieces and place in a large pot of
water.
2. Rinse the vegetable/fruit.
3. Fill the pot with clean water and let the vegetable soak for atleast 4 hours
at room temperature (overnight, if in refrigerator).
4. After soaking, rinse the vegetables.
5. Discard water.
6. Cook as desired and limit the portion size to no more than ½ cup.
Note:
Cauliflower, mushrooms, carrots, peas, potato, bottlegourd, guava etc. can
easily be leached.
Avoid vegetables/fruits which have a soft mushy texture (tomatoes,
pumpkin, bananas…..) as they would get dissolved in water during the
process of soaking.
Disadvantage: Leaching not only reduces the sodium and potassium content; it
also lowers the amount of water soluble vitamins and several minerals. It should
preferably be practiced only when sodium intake is restricted to ~500 mg/day.
180
Further, hyperkalemia has been found to be a critical factor related to morbidity and Planning Diets for
Renal Diseases
mortality among CRF patients. Therefore, potassium levels in blood can be maintained
by:
Avoiding processed foods.
Avoiding ‘low salt’ snacks/ready-to-eat foods, if table salt (NaCl) has been
substituted by a potassium salt.
Consuming a small serving size of fruits and vegetables even if they are inherently
low in potassium.
Adhering to the dialysis schedule.
We should choose low/high potassium foods (listed in Box 8.2) according to the blood
potassium levels.
Dairy Khoa, Yoghurt, Ice-cream. Non-dairy creamers, Rice milk Milk, Paneer
(unenriched), Non-dairy
whipped toppings.
Snacks Chocolate, Seeds & nuts, Salt Sorbet, Jelly, Hard Candies, Plain
substitutes Donuts, Unsalted Popcorn.

Fluid losses due to diarrhoea/ vomitting
Remember, we are here referring to the term “fluid” and not “water”. Thus, the
fluid allowance calculate will include:
Moisture present in food (ICMR food composition table)
Water present in prepared dishes (curries, vegetable preparations, curd etc.)
Water used in beverages or as such for taking medicines
Water as a beverage to quench thirst.
Spraying mouth washes, sucking ice-chips/chilled fruit/lemon drops or chewing
184 gums containing citric acid can be helpful when fluid is restricted.
Finally, let us study about nephrolithiasis. Planning Diets for
Renal Diseases
Calcium Stones
Struvite Stones
Cystine Stones
Although, role of diet in the formation of urinary stones is not well established, it is
advisable to have liberal fluid intake, a balanced diet and restrict foods based on the
main constituent of the stones. Table 8.4 gives information related to different stones
and their corresponding diet restriction.
Table 8.4: Different stones and their corresponding diet restrictions
Besides liberal fluid intake and some dietary restriction, urine pH control helps based
on the chemical composition of the stone, mainly via acidifying or alkalinizing agents
or diet. Binding agents to bind the stone constituent may also be used.
Enlisted below are a few examples of low, moderate and high sources of oxalic
acid and also food sources of phosphorous. You may use this information while
planning diets for renal stone patients where oxalate or phosphorous needs to be
restricted.

Case Study : Mrs. Darshan is a 65 years old woman who was admitted to the
ICU of renal ward. She had oedema, pale conjunctiva, shortness
of breath, chest pain, parasthesia and reduced urine output. She
was experiencing severe gastrointestinal disturbances such as
anorexia, nausea and vomitting due to which her food intake has
reduced drastically. Clinical diagnosis was indicative of chronic
renal failure with mild hyperkalemia, metabolic acidosis and
hypertension. Some of her clinical parameters are:
Glomerular filtration rate : 20 ml/min
Serum bicarbonates : 12 meq/L
Serum potassium : 5.3 meq/L
Systolic blood pressure : 156 mmHg
Diastolic blood pressure : 98 mmHg
Serum sodium : 150 meq/l
Serum creatinine : 1.9 mg/dl
Blood Urea Nitrogen : 29 mg/dl
Urine output in previous 24 hrs. : 326 ml
Her medical reports have been forwarded to the dietitian to help the patient with
dietary counseling and also to plan diet for Mrs. Darshan during her hospital stay.
Now plan a diet for Mrs. Darshan.

DISEASES
Structure
9.1 Introduction
9.3 Hypertension
9.4 Atherosclerosis
9.1 INTRODUCTION
Coronary heart diseases are a group of diseases of the heart. You may recall studying
about the coronary heart diseases in Unit 11 in the theory course (MFN-005). Some
of the common ones that we shall review in this practical are:
Hypertension
Atherosclerosis
Myocardial infarction
Congestive heart failure
These coronary diseases are of prime importance as we see that the incidence of
these diseases is rising at an enormous rate and they account for an appreciable
proportion of mortality and morbidity in the populations groups. The main focus in this
practical will be on the dietary guidelines and principles involved in planning diets for
these heart conditions.
Objectives
gain insight into the dietary management goals and modify diets according to the
guidelines, and
plan diet for patients suffering from hypertension, myocardial infarction and
220
congestive heart failure.
Nutr itio nal
9.2 CORONARYHEART DISEASE:AN OVERVIEW Management of
Coronary Heart
Di se as e s
Coronary heart disease is a leading cause of death in the general population, affecting
the majority of adults past the age of 60 years. Men are more likely to develop and to
do so at an earlier age than women.
Established multiple risk factors in coronary heart disease are -
a. Non-modifiable risk factors, which are the personal characteristics such as
sex, age and family history.
b. Modifiable risk factors, which are behavioural (such as smoking and sedentary
life-styles, food habits) (like excessive fat, excessive sugar, excessive salt etc.)
physiological (such as hyperlipidemia, obesity, diabetes mellitus etc.) and
psychological (such as stress).
Though we have already studied about the etiological risk factors and pathophysiology
of coronary heart diseases in detail earlier in the theory course, here in this practical
we will once again recapitulate some of the important coronary diseases, with the
main focus on the principles of dietary management. You may recall studying in section
11.4 in the theory course (MFN-005) about the preventive measures for coronary
heart diseases. WHO recommended nutrition guidelines for prevention of heart disease
include:
Sufficient calories to maintain appropriate weight for a given height
Total fat between 20-30% of total calories
Cholesterol not to exceed 300 mg/day
Saturated fats less than 10% of total calories
Polyunsaturated fats less than 8% of total calories
Linoleic acid between 3-7% of total calories
Alpha linolenic acid less than 1% of total calories
Proteins to provide 15-20% of total calories
Mentioned in Table 9.1 are details regarding nutrient intake and food choice checklists
that can be used as effective tools for modifying the dietary intake of the masses at
large as recommended by WHO.
Table 9.1 : Dietary recommendations for the prevention of
Coronary Heart Disease (WHO)
Calories : Sufficient to maintain ideal body weight
Total fat : 20-30% of calories
Cholesterol : < 300 mg/day
SFA : < 10% of total calories
PUFA : < 8% of total calories
P/S ratio : 0.8-1.0
Linoleic acid (LA/n-6) : 3-7% of total calories
Alpha linolenic acid (ALNA/n-3) : < 1 % of total calories
LA/ALNA ratio : 5-10
Proteins : 15-20% of total calories
Carbohydrates : 55-65% en with emphasis on complex
carbohydrates
Sugars : < 10% of total calories
Salt : 5-7 g/day
Dietary fibre : 40 g/day 221
Clinical and Keeping these recommendations in mind, let us now take up specific coronary heart
Therapeutic Nutrition disease conditions and study about their dietary management, in particular.
We begin our review with hypertension.
9.3 HYPERTENSION
Hypertension is usually defined as a blood pressure of 130/80 or greater. Normal
blood pressure is 120/80 or less. A systolic blood pressure of 120-129 and a diastolic
blood pressure of <80 is considered elevated blood pressure. Table 9.2 presents the
classification given by American Centre for Cardiology/ American Heart Association
(ACC/AHA), 2017 on Hypertension.
As for the causative factors, 90% of the times the etiology of hypertension is not
known. High blood pressure in the absence of any underlying disease is called primary
hypertension. Elevated blood pressure due to some underlying disease is secondary
hypertension. Increase in blood volume, heart rate and peripheral vascular resistance
can lead to hypertension. Being overweight, excessive intake of salt and lack of
physical exercise can all contribute to increase in BP.
Next, let us review the treatment and management of hypertension, with a focus on
nutritional management. We begin with the objectives of nutritional management.
to achieve gradual weight loss in overweight and obese individuals and maintain
weight slightly below the normal levels,
222
Modifications in diet and Recommended dietary allowances Nutr itio nal
Management of
Choosing foods low in calories and fat. Calorie requirement is based on the Coronary Heart
Di se as e s
concept of maintaining ideal body weight. Protein should contribute
15-20% of the total energy need. The fats incorporated in the diet should be
rich in unsaturated fatty acids and should not provide more than 20% of the
total energy.
Choosing foods that are low in sodium (salt).
Mild sodium restriction means 2-3 grams of salt/day.
Moderate sodium restriction means 1 gm salt/day.
Strict restriction means 0.5 grams a day of salt.
(Refer to Table 11.6 in Unit 11 and Table 16.2 in Unit 16 in theory course for sodium
content of some food items).
Choosing foods high in fiber. About 60-65% energy should be provided from
carbohydrates which are polysaccharides (complex carbohydrates) rather than
simple sugars (monosaccharides and disaccharides).
Maintaining a healthy weight or losing weight, if overweight.
Limiting serving sizes.
Increasing physical activity as it redistributes body water and eases transit of
blood through peripheral arteries.
Practicing moderation if consuming alcoholic beverages. In moderation alcohol
relaxes the peripheral arteries and so reduces blood pressure but high doses
clearly increases BP. Moderation means no more than one drink for women and
two drinks per day for men.
Adequate amounts of calcium, magnesium, potassium and vitamin C is also
necessary as the deficiency may lead the walls of the arteries to constrict causing
hypertension.
It has been proposed that fish oil supplements may have a variety of protective
cardiovascular effects, including a reduction in systemic blood pressure (BP).
Fish intake in combination with weight loss may have additive effects on blood
pressure reduction in hypertensive patients
Next, let us review the pathophysiology and the dietary management of atherosclerosis.
9.4 ATHEROSCLEROSIS
Atherosclerosis, you may recall studying, in sub-section 11.3.2 in Unit 11 in the Theory
Course (MFN-005), is a disease affecting arterial blood vessels. It is an arterial lesion
characterized by patchy thickening of the intima comprising of fat and layers of collagen
like fibres.
It is unknown exactly how atherosclerosis begins or what causes it. There is a gradual
build-up of plaque or thickening of the inside of the walls of the artery, causing a
decrease in the amount of blood flow, and a decrease in the oxygen supply to the vital
body organs and extremities. A heart attack may occur if the oxygenated blood supply
is reduced to the heart. A stroke may occur if the oxygenated blood supply is cut off
to the brain. Gangrene may occur if the oxygenated blood supply is reduced to the
arms and legs.
Atherosclerosis has been associated with the following risk factors such as elevated
cholesterol and triglyceride levels, high blood pressure, smoking, diabetes mellitus,
223
obesity, physical inactivity and older age.
Clinical and Next, let us learn about the nutritional management goals of this disorder.
Therapeutic Nutrition
Nutritional management goals
The nutritional management goals of atherosclerosis include:
Reduction of weight if overweight or obese.
Reduction in total fat, saturated fat and cholesterol.
Consuming a balanced adequate diet, rich in calcium, chromium, iron and zinc.
Medication if required for treating lipid disorders and controlling BP.
Lifestyle changes - increase in physical exercise, moderation in alcohol intake.
No smoking, restricting coffee.
Medical management is through various lipid lowering drugs.
Dietary modifications and the nutrient requirements for this condition are enumerated
next.
Modifications in diet and Recommended dietary allowances
Calories: to maintain ideal body weight
Carbohydrates should constitute 55-65% of calories with emphasis on
polysaccharides (complex carbohydrates)
Sugar less than 10% of total calories
Dietary fibre : >40 g/day
Proteins: 15-20% of modified energy
Fat: 20% of total energy
Dietary cholesterol: < 200-300 mg/day
Some other considerations include:
Saturated fatty acids (SFA) – SFA intake is associated with
hypercholesterolemia and atherosclerosis in humans. Some dietary SFAs like
palmitic, myristic (most potent) and lauric acids have the most hypercholesterolemic
effects as they elevate LDL-c. They are found in butterfat, coconut and palm
kernel oils. Saturated fat must constitute no more than 10% of calories.
Poly unsaturated fatty acids (PUFAs) PUFAs are known to lower total serum
cholesterol; especially the n-6 series is more beneficial. n-3 series also have
positive effects by reduction of platelet aggregation, as well as, favourable
changes on blood lipids and blood pressure. n-6 PUFAis found in corn, sunflower,
safflower and soybean oils. Sources of linolenic acid (n-3) include wheat, bajra,
Black gram, cowpea, rajmah, soyabean, green leafy vegetables, fenugreek and
mustard seeds (spices) apart from fish. Linolenic acid can also be obtained
from oils like mustard, soyabean, canola and rice bran oil. ICMR (1998) has
given dietary guidelines to maintain n-6/n-3 ratio of 5-10 and PUFA/SFA of
0.8-1.0 which ensures long-term health. Hence, the choice of cooking oil
should be:
a) Moderate linoleic acid oils (n-6) like groundnut oil, rice bran oil or sesame oil
OR
Soyabean oil [containing both linoleic and alpha linolenic acid (n-3)], and
b) Combination of two oils in approximately equal proportion:
Use high linoleic acid oils like sunflower oil, safflower oil and cottonseed oil
with palm oil (low linoleic acid)
OR
Mustard oil (containing alpha-linolenic acid) along with any other cooking
oil (this will reduce erucic acid from mustard oil and thereby its undesirable
224 health effects)
Include monounsaturated fatty acids. Its sources are olive oil, canola oil, Nutr itio nal
Management of
groundnut oil, rice bran oil, red palm oil and sesame oil. Coronary Heart
Di se as e s
Trans fatty acids : Trans fatty acids raise blood cholesterol levels, increasing the
risk of CVD though to a lesser degree than the saturated fatty acids. Patients
are recommended to restrict their trans fatty acid such as margarine, shortenings,
partially dehydrogenated oils, vanaspati ghee, cookies, crackers and fried foods.
Dietary cholesterol : Dietary cholesterol raises total cholesterol and LDL
cholesterol. It is found in animal foods such as meat, fish and poultry. Egg yolks
and organ meats are particularly rich sources. Limited intake of cholesterol i.e.
< 200 - 300 mg/d is recommended.
Dietary fiber : Soluble fiber sources include oats, legumes, fruit pectin etc. Soluble
fiber lowers serum cholesterol and LDL cholesterol, promotes insulin sensitivity,
increase satiety, promote lower energy intake, thus causing lower incidence of
CHD. Total fiber should be 40g/ 2000 kcal for adults, 25% of which should be
soluble. Two mechanisms are known for soluble fiber - (1) fiber binds bile acids,
which lowers serum cholesterol to replete the bile acid pool, and (2) bacteria in
the colon ferment the fiber to compound acetate, propionate and butyrate which
inhibits cholesterol synthesis.
Soy proteins : Soy have been found to decrease total cholesterol, LDL and
triglyceride without lowering HDL-c levels. Approximately, 50 g/d of soy protein
may be replaced with animal protein to achieve the cholesterol lowering effect.
The phytosterol and phytoestrogen content of soy protein also plays role in this
lowering. It may be found in tofu, soy milk, soy protein supplemented drinks etc.
Alcohol : When its intake is in excess, alcohol is related to cause adverse affects
causing liver damage and cirrhosis, cardiomyopathy and elevated blood pressure.
Moderate intake is related to lowering incidence of CHD in some populations.
Alcohol raises HDL cholesterol; wine contains an antifungal compound that
increases HDL cholesterol and inhibits LDL oxidation.
With these considerations, we end our study on atherosclerosis. Next, we shall
review myocardial infarction.
Long term diet therapy is implemented when the patient is out of immediate medical
danger. Diet is tailored to meet individual needs and deal with conditions such as
hyperlipidemia, hypertension, obesity and diabetes. The important aspects to be
considered include:
1) A low calorie diet (1200-1500) is used to avoid the metabolic stress caused by
larger intakes and to begin promoting weight loss. The energy intake may initially
begin with 800 Kcal which can be slowly progressed to a 1200 Kcal diet till the
patient is discharged. Thereafter, the patient’s energy intake should be governed
on the maintenance of body weight which is preferably 1 to 2 kg below ideal
body weight.
2) Large meals are avoided (more than 600-700 Kcal) because they increase heart
rate and stroke volume. Recommend the patient to adhere to small frequent
meal pattern.
6) When fats are needed for cooking, spreads, and other uses, recommend oils
with high amounts of monounsaturated and/or polyunsaturated fatty acids,
especially n-3 polyunsaturated fats such as canola, olive oils and soybean oil.
CHF results from decreased myocardial efficiency, it can be caused by an MI, valve
disease, thiamin deficiency and other conditions. Renal blood flow may decrease with
impaired excretion of sodium and water. Peripheral and pulmonary oedema with ascites
often results.
Nutritional care is a little difficult in congestive heart failure, since oedema complicates
the nutritional assessment of the subject. Nevertheless, the objectives of dietary
226
management are enumerated herewith.
Objectives of dietary management Nutr itio nal
Management of
Coronary Heart
The objectives of dietary management of congestive heart disease include: Di se as e s
Dietary goals in CHF are to increase energy intake because organ systems heart
and lungs must work extra hard to maintain their functions. Blood flow and nutrient
supply is affected and weight loss usually goes unnoticed due to anorexia and altered
taste. Thus CHF patients are subjected to protein-calorie malnutrition. Chronic PEM
which develops due to heart failure is called cardiac cachexia. Keeping the above
objectives in mind, let us review the nutrient requirements and the dietary modifications
required for the dietary management of this condition.
1) Patients on artificial oxygen support systems and/or those who are obese are
recommended 1200 Kcal diet. Ambulatory and /or normal weight patients are
usually able to tolerate around 20-25 Kcal/kg IBW per day. Providing adequate
calories is vital but providing too much may increase the metabolic stress on the
body taxing the heart.
2) About 1g of protein per kg ideal body weigh should be incorporated in the diet.
Since CHF is a form of cardiomyopathy and there is weakness of cardiac muscles,
it is essential to supply good amounts of dietary proteins particularly high biological
value proteins to facilitate tissue synthesis.
3) Fats should not provide more than 20% of the total energy and the diet should be
low in cholesterol (< 200 mg/day) depending upon the lipid profile of the patient.
4) Mild to moderate sodium restriction (2.0 - 3.0 g Na per day) is often beneficial
for most patients. Restriction of table salt and cooking salt is recommended for
all patients. High sodium fruits and vegetables such as fenugreek leaves, lettuce,
spinach, beetroot, tomato, grapes, musk melon, as well as, processed foods and
preserves should be avoided.
5) Dietary fiber is carefully adjusted. Goal is to provide more of soluble fiber than
insoluble fiber to avoid constipation and to prevent gas production.
6) For clients who are unable to eat, calorie and nutrient dense formulas are given
which have less water and can prevent PEM.
7) Fluid intake should be reduced to reduce the circulatory volume. It can range
from 1-1.5 lit/day.
Other considerations
Subjects with congestive cardiac failure often tolerate frequent meals better than
larger infrequent meals as these are tiring to consume, can contribute to abdominal
distention and markedly increase oxygen consumption. 227
Clinical and Alternative seasonings and flavouring agents such as mild herbs and condiments
Therapeutic Nutrition
may be used sparingly if sodium restriction is moderate to severe in order to
ensure adequate food intake.
The menu should be planned by keeping in mind the fluid allowance for the day.
The patient should be advised to chew the food slowly. Sweating and chest
discomfort are indicators of oxygen deficiency. Food ingestion should be stopped
in such situations.
Meals should be soft and well cooked. Raw food should be completely avoided.
If the patient is on ventilator, oral intake may not be feasible. In such situations;
enteral tube feeding should be started.
With these considerations, we end our study of congestive heart failure. We hope the
discussion above may have given you a good insight into the coronary heart diseases
and their dietary management. Let us then review what we have learnt so far by
answering the review exercises given next. After completing these exercises, we
can move on to planning diets for the disease conditions included in this practical.

Date : Aim : To plan a diet for a hypertensive patient
Case study : Mr Verma is a 50 yr old high school cricket coach. He is 80 kgs with
a height of 5^5^^ and smokes one pack of cigarettes a day. He is
admitted for further evaluation and for his essential hypertension. His
BP on admission is - 150/90
Chief complaint- “I have tried to cut down on my salt but food just doesn’t taste good
without it….I want to control my hypertension – my mother just passed away because
of a heart attack..”
Patient history- He has a strong family history of heart disease. He was given a diet
sheet of 2 gram salt diet (no added salt) since he was detected with hypertension but
he has not been able to eat properly since then as the food doesn’t taste good anymore
which discourages him to stick to the low salt diet and encourages him to skip his
meals or overindulge.
His wife is also working, so on an average, they eat out 2-3 times a week.
His doctor has prescribed some antihypertensive medications and wants him to see a
dietitian for a diet plan and low salt food list.
