FOREWORD
T
he Government of the United Republic of Tanzania is committed to improving the
nutrition and health status of all population groups. This is evident in the policies,
strategies, development plans and interventions aimed at reducing all forms of
malnutrition in the country. Like other developing countries, the United Republic of Tanzania
is experiencing multiple forms of malnutrition, leading to impaired cognitive development,
reduction in learning abilities, and negatively impacting labour productivity. Although there
is good progress in reducing the prevalence of stunting, the rapid increase in overweight
and obesity adds a new dimension to the strategies for addressing malnutrition. Some
of the contributing factors to this scenario include changing consumption patterns and
lifestyles, especially of those living in urban areas.
In response to this, the Ministry of Health, through the Tanzania Food and Nutrition
Centre (TFNC) and the Food and Agriculture Organization of the United Nations (FAO), has
developed the first national Food-Based Dietary Guidelines (FBDGs) for a Healthy Population
through a broad consultative process. The information collected through a literature review
generated an evidence report that showed gaps and needs for guidelines. FAO supported
this process by providing financial and technical assistance.
These FBDGs Technical Recommendations manual serve as the official document addressing
the principles and recommendations of a healthy diet and lifestyle. It will be an important
tool to support food and nutrition information and educational activities in the country. The
manual complements the existing efforts done through (i) nutrition-specific and nutrition-
sensitive interventions, (ii) guidelines on improving micronutrient nutrition, (iii) Infant and
Young Child Feeding Policy and Guidelines, and (iv) fortification strategies. It also supports
the implementation of the National Multisectoral Nutrition Action Plan (NMNAP II 2021–
2026). Furthermore, we envision that these guidelines will help to strengthen the linkages
between agricultural, nutrition and health.
The FBDGs Technical Recommendations manual is intended for technical people such as
nutritionists, researchers, development partners, community nutrition educators, health
personnel, teachers and other stakeholders working towards improving the nutrition and
health status of the general population of the United Republic of Tanzania. I, therefore, urge
all stakeholders to support the implementation of the FBDGs for the improved nutrition
and wellbeing of Tanzanians. I believe that the FBDGs will play a key role in improving the
food consumption patterns and nutrition outcomes of Tanzanians.

4. THE DIETARY GUIDELINES AT A GLANCE
The Tanzania FBDGs are structured around six guidelines:
• Guideline 1 is about increasing dietary diversity through consumption of the six
food groups daily to promote health and wellbeing for all age groups.
• Guideline 2 encourages optimal nutrition for populations with special needs
(pregnant and lactating women, infants, and young children, as well as school-
aged children).
• Guideline 3 contains a set of recommendations on limiting calories from sugars,
saturated fats, trans fats, ultraprocessed foods and reducing salt intake for all
age groups.
• Guideline 4 provides guidance on keeping food, water and home environment
clean to support better nutrition and healthy outcomes for all age groups.
• Guideline 5 promotes an active lifestyle for healthy weight for all age groups.
• Guideline 6 is on limiting alcohol consumption and restricting tobacco use to
reduce non-communicable disease (NCD) risks for all age groups.
Each guideline is accompanied by key recommendations intended to inform individuals
and households on how to choose combinations of foods and beverages as well as
behaviours to promote health and prevent malnutrition. In each recommendation,
there are specific tips to help the consumers practise a healthy lifestyle.

5.5 Key messages for eating a variety of foods from
the six food groups
1. Everybody, young and old, should enjoy eating a variety
of foods from different food groups every day to stay healthy
and strong.
2. Eat staples such as cereals, starchy roots, tubers or plantains every day
for a strong and active body. Make whole-grain products a major part of
your staples.
3. Eat different coloured vegetables every day to prevent and reduce the
risk of diseases.
4. Eat at least two different fruits every day for better health.
5. Eat pulses, such as beans, lentils, peas or nuts every day for good health.
6. Eat animal-source foods, including seafood, meat, milk or eggs, every
day to stay strong.
7. Limit your intake of deep-fried and highly processed foods that contain
fat, sugar and salt to prevent diseases such as high blood pressure,
diabetes and heart diseases.
5.6 Tips for eating diversified meals
1. Choose different types of staples in a week, including whole grains, green
bananas, starchy roots, and tubers.
2. Make your plate colourful. Combine different coloured vegetables, roots,
tubers, and pulses in your meals.
3. Eat mixed food. Adding different food groups to relish is a great way to
eat many food groups in one meal.
4. Share a variety of meals with the whole family.
5. Planning your meals ahead can help you eat a greater variety of foods.
6. Grow different types of vegetables and fruits in a backyard garden for a
continued supply of a variety of foods.
7. Keep animals such as chickens, rabbits, goats and fish to help you access
animal-source foods easily.
8. Store food safely to ensure a sustainable supply of various
food types.
9. Avoid drinking tea during or soon after a meal. Tea
binds dietary iron and makes it unavailable.
10. Eat the right amounts food from each food group.

6.6 Key messages for eating staples
1. Eat four servings of staples per day and make at least
one serving wholegrain for a strong and active body.
2. Eat different varieties of cereals, starchy roots, tubers,
plantains and green bananas throughout the week as a
good source of energy and vitamins.
3. Make staples one-third of your plate, not all of your plate.
4. Choose fortified maize or wheat flour over unfortified
products.
5. Sort to remove mouldy or discoloured grains before processing as they
may contain harmful toxins.
6.7 Tips for increasing intake of whole grain cereals and eating a
variety of staples
1. Replace refined grains such as white maize and rice with whole grains
such as unrefined maize, sorghum ugali and brown rice whenever
possible.
2. Include whole grains in your daily meals to get fibre that aids
digestion and reduces the risks of overweight and NCDs.
3. Make starchy foods part of a meal, taken together
pulses or animal source foods, and vegetables.
4. Add a variety of starchy roots and tubers such as sweet
potato, cassava, yams, and taro to your diet.

7.5 Key messages for eating vegetables
1. Eat at least two servings (280 g) of seasonally available
vegetables every day.
2. Choose different coloured vegetables throughout the
week to increase the variety of nutrients. A variety of colours
will provide different types of phytochemicals.
3. To enhance absorption of pro-vitamin A, add a small amount (1–2
teaspoons) of vegetable oil when cooking leafy green or yellow
vegetables.
4. Choose fresh or frozen vegetables rather than vegetable juices.
7.6 Tips for eating a variety of vegetables every day
1. Wash vegetables with clean water just before cutting/chopping to
prevent loss of nutrients.
2. Cover and cook for a short time in a small amount of water at low
temperature to preserve nutrients.
3. Avoid discarding water after boiling vegetables.
4. Buy fresh vegetables in-season for better value and quality.
5. Start your own home vegetable garden to increase accessibility of
vegetables every day.
6. Include cucumbers, mushrooms, tomatoes, pumpkin and carrots as part
of vegetables.
7. Do not add bicarbonate of soda (magadi) or ash (majivu) to cooking
vegetables as it destroys some nutrients.
8. Do not overcook vegetables as heat destroys some
vitamins.
9. Eat vegetables such as cucumber, carrots and
tomatoes as a snack.
10. Preserve vegetables by drying so they can be
enjoyed when out of season.

9.5 Key messages for eating pulses, nuts and oily
seeds
1. Eat pulses such as beans, peas, lentils, cowpeas, pigeon
peas, and soya daily.
2. Eat a handful of unsalted nuts or oil seeds every day as
a snack.
3. Eat pulses, nuts or seeds together with fruits or
vegetables. Vitamin C in fruits and vegetables enhances iron absorption.
4. Feed cooked beans, lentils and peas to infants and young children aged
6–24 months to increase iron and protein intake.
5. Include pulses (legumes), nuts, and oil seeds in the diet of pregnant and
lactating women.
9.6 Tips for eating three servings of pulses, nuts and oil seeds
every day
1. Soak beans overnight to get rid of gas-producing antinutrients
and make them easier to cook.
2. Add the paste and/or flours of nuts or oil seeds to your
relish, vegetables and porridge.
3. Avoid adding soda or ash when cooking pulses.
4. Mix pulses with whole grains to improve protein
quality.

10.5 Key messages for healthy eating of animal-
source foods
1. Eat at least two servings of fish, poultry, milk, or egg every
day.
2. Eat fish as often as possible each week. One or two servings
should be from fatty fish, such as Nile perch (sangara).
3. Choose small fish eaten with bones, such as fresh sardines,
to get the benefits of calcium.
4. Eat more white meat, insects, and eggs than red meat. White meat,
such as fish and poultry (without skin), are lower in saturated fat than
red meat.
5. Limit intake of red meat to less than 160 g (size of two palms) per week.
6. Avoid eating processed meats such as sausages, luncheon meats,
polony and ham.
7. Avoid eating cheese with a lot of salt.
8. Limit intake of ice cream, butter, and cream which are high in fat, sugar
and salt.
9. Pregnant and lactating women should take special care to include
poultry and meats in their diet.
10. Offer poultry, meats and eggs to infants and young children aged 6–24
months.
11. Give plain, full-cream milk only to children above one year whenever
possible.
10.6 Tips for healthy intake of animal-source foods
1. Add an egg or milk to porridge or meals intended for children.
2. Eat unsweetened yoghurt and add fresh fruit to reduce sugar intake.
3. Use low-fat or skim milk to lower the amount of saturated fat for adults.
4. Use milk and milk products with little or no added sugar.
5. Share fish, sardines, chicken, milk, eggs and meat with
everyone in your family.
6. Trim fat off the fish, meats and discard poultry skin
before eating.
7. Grill, pan-fry, steam, boil or bake instead of deep
frying.
8. Cook meat thoroughly to prevent food-borne illnesses.

11.7 Key messages for healthy eating of unsaturated
oils and fats
1. Use 28 g or 2 tablespoons of added oils to food per day.
2. Choose liquid vegetable oils (e.g. sunflower, groundnut,
olive, sesame (simsim) and avoid palm oil, coconut oil,
butter or ghee.
3. Eat oily fish and oily seeds and nuts often to get essential fatty acids.
4. Avoid intake of trans fats mostly found in ultraprocessed foods and
fried fast foods.
5. Use coconut milk in moderation; not more than one-third of a cup
per person per day.
11.8 Tips for eating small amounts of unsaturated oils and fats
1. Stir-fry foods instead of deep-frying foods.
2. Cut out visible fats from meats and discard poultry skin before
cooking. Animal fats contain large amounts of saturated fats.
3. Choose lean cuts of meats with less visible white streaks of fat.
4. Do not add extra oil or fat when cooking meats and poultry.
5. Avoid processed foods containing trans-fatty acids.
6. Read food labels and avoid buying foods with
partially hydrogenated oils in the ingredients list.
Partially hydrogenated oils are made industrially in
commercial settings to boost flavour and increase
shelf life.

MYTHBUSTER! MATERNAL DIET AND MILK QUALITY
Although the quality of milk is not affected by the mother’s diet quality1 (WHO,
1985; Prentice et al., 1989; Hartmann et al., 1985; Greiner, 1994) a healthy,
varied diet with extra amounts of foods rich in these nutrients is important
as the mother will have to replace the nutrients lost through breastfeeding.
If nutrient intake is lower than the total demand for both maternal
maintenance needs and milk production, the mother's body will mobilize
available nutrients from body tissues to maintain a constant breastmilk
quality and quantity. Thus, additional nutrients are important for mothers’
healthy weight, proper function of the body, body repair and protection
against diseases.
1
Studies have found that there is no dose response relationship between diet and human lactation and that, in general,
reductions in the quality and quantity of breast milk, and reductions in infant growth have been difficult to find even among
malnourished women who breastfeed for long periods. Further, empirical evidence has not been able to demonstrate
reduced energy or protein levels in breast milk of malnourished women. Some of the reasons for constant breast milk
quality is that the woman’s metabolic rate becomes more efficient during breastfeeding and at times the woman’s body will
mobilise available nutrients from her own body tissues to meet produce breastmilk in case of low dietary nutrient intakes
(WHO, 1985; Prentice et al., 1988; Illingworth et al., 1986; Frigerio et al., 1991; Whitehead, 1979; Deem, 1931; Hartmann et

102 Tanzania Mainland Food-Based Dietary Guidelines
13.6 Key messages for exclusive breastfeeding
1. Breastfeed babies exclusively on demand from
immediately after birth to six months of age because
breast milk contains all the food and water the baby
needs. Breastfeeding responsively ensures that babies
will receive all they need to grow well and remain healthy.
2. Do not give babies any water, tea, honey, sugar water,
salt, juice or any other foods before six months to reduce
the risk of diarrhoea, infections or death.
3. Breastfeed as soon as possible within the first hour of birth to boost
the child’s immunity from colostrum (first milk) and prevent newborn
deaths (WHO, 2017b). The colostrum is the baby’s first shot of natural
immunization.
13.7 Tips for exclusive breastfeeding
1. Initiate breastfeeding immediately after birth or within the first hour
to stimulate breast milk production and promote better milk flow.
2. Breastfeed your baby when it shows a sign of hunger without counting
the hours after the last breastfeeding.
3. Breast milk can stay at room temperature for up to four hours. If you
have to be away from the baby for a while, express breast milk into a
clean container and leave it covered for the baby.
4. Breastfeed your baby until your breast is empty
before shifting to another breast.
5. There are signs to let you know if the baby is
getting enough breast milk. These signs have
been explained in section 13.4.

14. RECOMMENDATION 2.3
FROM SIX MONTHS, FEED YOUR BABY A VARIETY OF FOODS FROM
ANIMAL SOURCES, PULSES, FRUITS AND VEGETABLES, AND CONTINUE
BREASTFEEDING UP TO 2 YEARS OF AGE OR BEYOND FOR HEALTHY
GROWTH AND DEVELOPMENT OF YOUR BABY
From birth until 6 months, breast milk provides all the nutrients and energy required
for the growth and development of the infant.
As per table 15 and Figure 5, the nutritional needs of an infant increase significantly
after 6 months of age and the child, therefore, needs other foods in addition to breast
milk to supplement its energy, protein, vitamin and mineral requirements. Feeding the
child with other foods in addition to breastfeeding is known as complementary feeding
.

the six different food groups and continue breastfeeding to
support their growth and development.
2. Give beans, peas, lentils, nuts and seeds to infants and
young children daily from 6 months of age.
3. Give green leafy vegetables and yellow- or orange-coloured vegetables
and fruits daily to infants and young children. Add a little vegetable oil

4. Give children clean and safe water to drink. Do not give infants and
young children honey, tea, sugary drinks or salty foods.
5. Give prepared foods immediately after cooking and cooling.
6. Give food 2–3 times a day for infants 6–8 months old, while continuing
to breastfeed.
7. Give food 3–4 times a day for infants and young children between 9–24
months, while continuing to breastfeed.
8. When a child is ill, offer them more fluid including breastmilk and
favourite foods from 6 months of age.
9. Offer a variety of starchy foods such as orange-fleshed sweet potato,
cassava, and provitamin A maize, in addition to rice to children over 6
months.
10. Prepare foods for infants and young children with clean and safe water.
14.7 Tips for for feeding a baby
1. Introduce only one new food at a time, then combine foods later.
2. Introduce iron-rich foods such as pureed meats, liver, kidney, egg yolk,
fish, and chicken to babies after six months of exclusive breastfeeding
daily.
3. Give fatty fish regularly, taking care to remove the
bones.
4. Choose vegetable oils such as sunflower and
peanut oils.
5. Give avocado for healthy fats.
6. Give prepared foods immediately after cooking.

15.2 Key messages for feeding children aged 2 to 5
1. Give family meals that contain a variety of foods from the
six food groups to ensure a child gets all the nutrients they
require.
2. Give a child three meals and one or two nutritious snacks
a day.
3. Include fish or animal-source foods such as eggs, poultry, meat and
milk products.
4. Give children orange-coloured vegetables, fruits and tubers such as
papaya, ripe mango, pumpkin, pumpkin flowers, orange-fleshed sweet
potatoes, whole grain yellow maize, and dark leafy vegetables.
5. Give children pulses, nuts and seeds. Adding pulses or nut powders is a
great way to add nutrients to a child’s meals.
6. Avoid adding too much spice, sugar and salt to a child’s food.
15.3 Tips for quality, frequency and amount of food to offer children
aged 2 to 5
1. Serve a child’s food on his or her own plate or bowl to ensure children
eat enough food.
2. Give fatty fish regularly, taking care to remove the bones.
3. Grow and use biofortified crops like orange-fleshed sweet potatoes,
yellow maize and biofortified beans.
4. Add nutrient-rich food powders like bean, nut and fish powders and
moringa powder to children’s meals. Adding moringa
is a great way to fortify and enrich a child’s meals
because the moringa leaf contains a much higher
nutritional value of iron, calcium and complete
protein, as well as vitamins A, C, B2, B6 and
various minerals compared to other foods. The
moringa tree grows easily and quickly.

people re-use oil used for frying to cook
other foods. It is important to discard
leftover oil after deep frying and avoid
reusing used cooking oils.
Tanzania Mainland Food-Based Dietary Guidelines 127
17.2 Key messages for limiting intake of
fried foods
1. Avoid buying or cooking fried foods. Choose
alternatives such as baked, boiled or grilled products.
2. Avoid reusing oil because reheating oils creates trans-

3. Grill or stir-fry instead of deep frying.
17.3 Tips for reducing intake of fried foods
For those occasional times you have to fry foods:
1. Never let the food go brown or burn during frying.
2. Use vegetable oils when you fry.
3. Drain excess oil from food before eating or use
a paper towel to remove excess fat.
4. Make consumption of home-fried foods an
occasional treat just a few days a month.

18.1 The NOVA food groups
The degree to which a food is processed makes some foods unhealthy. The NOVA
food classification system categorises foods into four groups according to the nature,
purpose, and extent of the processing the food undergoes after it is separated from
nature (Monteiro et al., 2016).
Tanzania Mainland Food-Based Dietary Guidelines 129
Group 1: Unprocessed or minimally processed foods
Unprocessed foods are edible parts of
plants and animals in their natural state
without going through any alterations after
removal from nature.
Examples of unprocessed foods include
plants such as seeds, fruits, leaves, stems,
roots and animal products such as meat,
muscle, offal, eggs and fresh milk. Other
foods include fungi, algae and water.
Minimally processed foods are natural
foods that have gone through basic
processes such as drying, crushing, filtering
and packaging. Other such processes
include removal of unwanted parts,
grinding, fractioning, filtering, roasting,
boiling, pasteurization, refrigeration,
freezing, placing in containers, and non-
alcoholic fermentation.
Examples of minimally processed foods
include:
• milled and packaged grain flours;
• dried herbs, vegetables, fruits;
• frozen fresh meats, poultry, fish;
• frozen fruits and vegetables;
• boiled and fried meat or fish (without
salt added); and
• pasteurised milk.
The purpose of processing is to increase shelf life and storability and enhance the
edibility and digestibility of food. Minimally processed foods do not have sugar, salt,
oil or other substances added. This food moves very quickly from the farm where it is
harvested to the shop where it is sold or to the place where it is consumed.
Unprocessed or minimally processed foods are wholesome and nutrient dense. Make
unprocessed or minimally processed foods a major part of your diet. Use unprocessed
or minimally processed foods to make delicious, wholesome and healthy meals.

130 Tanzania Mainland Food-Based Dietary Guidelines
Group 2: Processed culinary ingredients
Processed culinary ingredients are
extracted and purified from natural foods
(minimally processed food) through
pressing, refining, grinding, crushing,
pulverizing and refining.
They are typically not eaten on their own
but are mainly used as condiments in
homes and restaurants to season or add
taste to natural foods when making freshly
prepared dishes and drinks.
This group does not include ingredients
that underwent further modifications,
such as hydrogenated fats (margarine,
other spreads or other trans fats) or
modified starches as these are considered
ultraprocessed foods (Monteiro et al.,
2019).
Examples of processed culinary ingredients
include:
• salt;
• sugar;
• cooking oil;
• honey;
• apple cider vinegar; and
• maple syrup.
Processed culinary ingredients typically consist of only one macronutrient in highly
purified form (mainly fat, sugar or carbohydrate) and therefore have low nutrient
density. Thus, limit use and consumption of this group.
Tanzania Mainland Food-Based Dietary Guidelines 131
Group 3: Processed foods
Processed foods are simple food products
made by adding Group 2 foods like salt,
sugar, and oil to natural or minimally
processed foods (Group 1 foods).
Most processed foods have two or three
ingredients. These foods are recognizable
as modified versions of Group 1 foods and
retain most constituents of the original
food.
Processed foods can have some additives
to preserve their original properties or
prevent spoilage and increase food safety,
for example, adding antioxidants to fruits
in syrup or adding preservatives to dried
salted meats.
Examples of processed foods include:
• canned or bottled vegetables, fruits
and pulses in brine (salt water) or
vinegar;
• canning of fish or bottling of fruits
preserved in syrup;
• cured, dried or smoked fish or
meat (with added salt and other
ingredients);
• tinned fish preserved in oil;
• salted or sugared nuts and seeds;
• simple non-alcoholic fermentation
like beer, sweet beer (tongwa), wine
and cider;
• bakery freshly made bread;
• cheese; and
• fortified foods like flours with added
nutrients such as vitamin A, calcium
or vitamin D.
Large amounts of sugar, salt or oil can make processed foods nutritionally unbalanced.
Therefore, just like processed culinary ingredients, they should be used sparingly
and only occasionally. Make delicious dishes and meals from natural and minimally
processed foods as a basis of the diet.

132 Tanzania Mainland Food-Based Dietary Guidelines
Group 4: Ultraprocessed foods
Ultraprocessed foods are industrial
formulations usually with five or more
ingredients produced through a series of
processes.
In addition to sugar, salt, oils and fats,
they contain other substances that are not
commonly used in home food preparation,
such as non-sugar preservatives,
sweeteners, colourants, flavourings and
emulsifiers (Monteiro et al., 2016).
The industrial formulation of these foods is
made entirely or mostly from substances
extracted from foods such as oils, fats,
sugars, starches and protein, or derived
from food constituents or synthesized in
laboratories. Thus, ultraprocessed foods
have little or no natural foods from Group
1.
These products are designed to be highly
palatable and contain high amounts of
sugar, salt, fat (mainly trans fats), and
chemical additives.
Some examples include:
• beverages like sugary drinks;
• confectioneries like biscuits and
cakes;
• snacks like crisps and sweets;
• Processed meats like corned beef;
• Baby food and milk formula; and
• Condiments like instant gravy and
and stock cubes
(See Table 24 for a detailed list)
Due to high levels of trans fats, salt, sugar and chemical additives, ultraprocessed
foods are linked to several non-communicable diseases and ill health. Because of

The processing and ingredients used to make ultraprocessed foods are nutritionally
unbalanced (Moss, 2013; Brownell, 2012). However, it is important to note that
added vitamins and minerals do not make highly processed foods healthy as they
do not contain the numerous beneficial phytochemicals and nutrients that natural or

*Most restaurant fast foods are ultraprocessed foods as they use hydrogenated oils. Although
fast-food chips may look much the same as home-cooked chips, their formulations and the
ingredients used in their pre-preparation and cooking render them ultraprocessed.
Monteiro et al., (2016) note that Group 4 also includes foods from Groups 1 or 3 that have
additives, such as plain yoghurt with added artificial sweeteners and bread with added
emulsifiers. In addition, alcoholic drinks fermented and then distilled to make alcohol such as
whisky, gin, rum and vodka are also considered Group 4 foods.

18.4 Key messages for avoiding the consumption of
ultraprocessed foods
1. Limit intake of ultraprocessed foods.
2. Limit intake of sugar-sweetened beverages such as carbonated
drinks and fruit-flavoured juice drinks.
3. Read food labels and avoid foods with ingredients such
as emulsifiers, flavouring, flavour enhancers, colouring and
texturisers.
18.5 Tips for avoiding the consumption of ultraprocessed foods
1. Avoid foods with long list of ingredients containing more than five ingredients,
including salt, trans fats (hydrogenated oils) and sugar.
2. Avoid foods with ingredients not found in homes or used in cooking
homemade food.
3. Avoid food labels with unrecognizable components or with very unfamiliar
names.
4. Avoid foods with any ingredient extracted from nutrient components like
sugar (e.g. lactose or fructose), protein (e.g. casein) or fat like hydrogenated
oils (trans fats). These ingredients end with “ose” (lactose, fructose) or “ein”
(casein).
5. Avoid foods with ingredients like nitrates, nitrites, benzoates, saccharin and
sorbates.
6. “Fresh food” with a long shelf life may indicate the presence of preservatives.
Check the label and avoid foods with preservatives such as sodium benzoate,
nitrate, sulphite, BHA and BHT.
7. Watch out; ultraprocessed foods are often marketed as healthy, natural or
organic. While these words may describe the original ingredients, they do
not refer to the process of how the food was made. Remember, an organic,
natural cookie is still an ultraprocessed food.
8. Do not get swayed by aggressive marketing and branding,
attractive packaging and the low cost as you pay a high cost
with your health.
9. Cook more often: make delicious meals with fresh
ingredients. Heating up frozen pre-made foods does
not count.
10. Make fresh, natural or minimally processed foods the
basis of your diet.

22.4 Key messages for keeping food, water and the
home environment safe
1. Wash your hands thoroughly with soap and clean running
water:
• before preparing, serving and eating food;
• after visiting the toilet, changing a baby’s nappy and caring
for a sick person; and
• after completing household tasks such as cleaning toilets and rubbish
pits.
2. Wash food containers, cutting boards, and utensils with soap and
clean water before and after each use.
3. Keep fresh fruits and vegetables and prepared foods away from raw
meats, poultry, and fish to avoid cross-contamination.
4. Cook meats, poultry, and fish thoroughly.
5. Boil raw milk before drinking.
6. Do not leave cooked food out at room temperature for more than two
hours.
7. Prepare foods for infants and young children with clean and safe
water.
8. Clean surfaces and knives with soap and safe water before cutting
fruits and vegetables, especially if these are to be eaten raw or cooked
at low heat.
9. Wash fruits and vegetables with clean and safe water before preparing
or eating.
10. Prepared foods should be stored in food-safe containers.
11. Avoid using plastic bags to store prepared foods as it is likely that the
bags are not sanitary. Plastics that are not food-safe tend to leach
harmful chemicals into the food.
154 Tanzania Mainland Food-Based Dietary Guidelines
22.5 Tips for keeping food, water and the home environment safe
1. Eat food immediately after cooking. Don’t let it sit around.
2. Read the labels of packed foods to know the expiry date.
3. Clean chopping boards with running water and soap before and after use.
4. Do not dry your hands on your clothes as this can easily transfer microbes.
5. Use clean towels to clean up during food preparation and serving.
6. Prepare and cook the amount of food that you intend to consume to avoid
leftovers.
7. Do not taste foods with any utensil used to either mix or stir
foods.

n: No figures are given for dietary iron requirements in pregnant women because the iron balance in pregnancy depends not
only on the properties of the diet but also on the amounts of stored iron.
s: The increased iron requirement cannot be obtained from the diet and thus daily supplemental iron and folic is recommended
during pregnancy and for at least three months after delivery (WHO, 2012b).
s**: Pregnant women should take Vitamin A supplementation in addition to diet.
s*: A single dose of 200,000 IU should be taken no later than eight weeks after delivery in addition to diet.
s*** Pregnant women take daily oral folic acid supplementation and, where possible, women should take folic acid supplements
before conception.
Energy and all other nutrients listed above can be met by eating a variety of foods.
NB: Calcium: No calcium levels for first and second trimester given, hence pre-pregnancy levels are assumed.
NB: Selenium: No selenium levels for first trimester given, hence pre-pregnancy levels are assumed.
