3.1 Malnutrition
The prefix “mal” means bad and when coupled with nutrition would imply bad nutrition.
Therefore, malnutrition can refer to both overnutrition or undernutrition. Overnutrition occurs
when there is an overconsumption of nutrients from food or supplementation to the point where
health is adversely affected.This could manifest as excessive caloric consumption leading to
obesity or consuming some vitamins or minerals in high amounts. Undernutrition occurs when
there is insufficient consumption of nutrients. This can manifest as impaired growth and
development or specific vitamin and mineral deficiency diseases such as scurvy, which is a
vitamin C deficiency (Collier R., 2009). It is important to understand that there may not always
be clear signs of malnutrition, initially. The potential serious effects will often develop over time.
Additionally, modern revelation teaches us that the physical well-being of an individual is
inseparably connected with their spiritual health. The biblical story of Daniel, Shadrach,
Meshach, and Abednego is an excellent example of the interconnection of dietary choices with
physical, mental, and spiritual health. (The Holy Bible, KJV, 1979). After being true to their
covenants and rejecting the king’s delicacies and wine for their traditional diet (likely rich in
beans and whole grains), these young men were blessed both physically and spiritually. It works
the same for each of us today: effort to stay true to our covenants and also care for the bodies we
have been given results in not only physical blessings, but spiritual blessings as well.
3.2 Undernutrition
Increased access to food, supplements, and medical treatment has reduced the number of those
suffering with inadequate nutrient intake. Nonetheless, it was estimated in 2018 that more than
800 million people globally are undernourished(United Nations World Food Program, Report on
Food Crisis, 2020). Many of these individuals are children. Inadequate intake of calories,
protein, and micronutrients (such as iron, vitamin A, and iodine) is still common globally. The
percentage of the population that suffers from undernourishment is diminishing, but with the
current level of population growth the actual number of those people that are undernourished
continues to increase. The term "food insecurity" is used to describe the lack of consistent
access to sufficient amounts of safe and nutritious foods. The key drivers of food insecurity
globally are armed conflict, internal violence, and civil unrest or political crises within countries
or regions that leads to the displacement of people from their homes. Other factors include
weather extremes and changing weather patterns, unexpected disease outbreaks such as COVID-
19, crop pests, and other economic challenges such as high unemployment rates or inflation. In
many places a poor infrastructure and lack of access to technology aggravates the food security
issues.
Even where sufficient calories from food may appear to be available many people may still suffer
from hidden hunger. Hidden hunger refers to inadequate intake or absorption of vitamins and
minerals. This is common with undernourishment but can also occur when caloric intake is
adequate if there is a limited variety of food available. For example, a person could eat enough
rice and beans to fulfill calorie needs, but without adding fruits and vegetables to the diet, vitamin
and mineral deficiencies will still occur. In developed countries, hidden hunger may be present
from heavy consumption of food rich in calories but low in vitamins and minerals. A moderately
low intake of vitamins and minerals may not result in any noticeable physical signs of a
deficiency but may still impact a person’s quality of life. Health professionals often refer to this
as a sub-clinical deficiency (inferring the absence of clear physical signs of the deficiency). An
example of this would be an increased rate of infection with marginally low vitamin A intake, but
the absence of more severe symptoms of low vitamin A intake such as blindness.

Regardless, whether noticeable nutritional deficiencies are physically present or not, inadequate
dietary intake affects the quality of life and an individual and a community’s ability to flourish.
Inadequate nutrition is detrimental at any time during the lifecycle but can be especially
concerning if it occurs in the first 2 years of a child’s life. Good nutrition during this time is
essential to support the rapid brain development that is occurring. Nutrition status of children can
be determined by following growth measures such as height, weight and mid upper arm muscle
circumference. Severe undernutrition can contribute to stunted height (low height for age) and/or
wasting (low weight compared to a person’s height). It is estimated that 144 million children
under 5 are stunted and 47 million are wasted worldwide (World Health Organization, 2020). It
is important to recognize the significance of these statistics. Good nutrition contributes to
cognitive development, resulting in better opportunities for children to realize their potential
academically, professionally and economically later in life. This impacts their quality of life as
well and the economic growth of their country. Poor nutrition, on the other hand, impairs
productivity, increases health care costs, and can perpetuate a cycle of poverty and ill health
(World Health Organization, 2020). Undernutrition is linked with suppression of the immune
system; consequently, undernourished children commonly die from bacterial or viral infections
(diarrheal diseases, respiratory infections, tuberculosis etc…). In 2020, the World Health
Organization reported about 45% of deaths among children under 5 years of age are linked to
malnutrition. The majority of these deaths occurred in low- and middle-income countries (World
Health Organization, 2021).
It is also important to consider that even when food amount and variety is plentiful that
undernutrition can still occur. This may be induced by personal choice. Sub clinical deficiencies
and hidden hunger can occur simply by making nutrient poor food choices from the options that
are available. This path to undernutrition might more commonly be seen in developed countries
where appealing, ultra processed nutrient poor foods are readily available and cleverly marketed.
Vitamin A
Vitamin A is a fat-soluble vitamin (chemically interacts well with fat). It is found in food in both
the active form of the vitamin and in a provitamin form which can be converted by the body to
the active vitamin. (National Institute of Health, Office of Dietary Supplement, 2022) The active
vitamin A is referred to as preformed vitamin A and has three forms (retinol, retinal and retinoic
acid) that are collectively referred to as the retinoids. Vitamin A provitamins come from the
carotenoid family. The three most important members of the carotenoid family that are vitamin A
provitamins are beta-carotene, alpha-carotene, and beta-cryptoxanthin. Vitamin A has several
roles in the body, which include maintaining vision, immunity, reproduction, growth and cellular
differentiation (helping stem cells become specialized cells) (BYUI, Principles of Nutrition,
2022).
Individuals that take too much of the retinoids through supplementation are also at risk of
toxicity. Consequences of taking too much can cause a variety of symptoms that may eventually
lead to death. If excess consumption occurs in pregnancy issues can occur at much lower levels,
problems can include spontaneous abortion (miscarriage of a pregnancy) and fetal malformations
(of a developing baby if the individual is pregnant) (World Health Organization, 2009)
Vitamin A Recommendations
There are several food sources of vitamin A. Some sources provide the provitamin (beta-carotene
or other carotenoids) and some foods provide the active form (the retinoids).
Eggs Pumpkin
Butter Peaches
Cheese Carrots
Iron
Iron is a mineral that is needed by the body for oxygen transport and production of usable energy
in the body. Hemoglobin is part of the red blood cell that carries oxygen. It is made up of heme
and globin. Heme is a ring-like structure containing carbon, hydrogen, and oxygen. Globin is the
protein that holds the heme. Iron is found in the center of each heme. When all these components
are present, hemoglobin is an efficient carrier of oxygen. In the muscle, a similar structure used to
transport oxygen is called myoglobin. The majority of the body’s iron (approximately 70%) is
found in the red blood cells of hemoglobin and myoglobin. Iron is also necessary to convert the
food we eat into usable energy. It is also a cofactor for hundreds of enzymes and is needed to
make DNA. (Principles of Nutrition, 2022)
Who is at risk?
Iron deficiency affects over 2 billion people worldwide. It is the most common nutritional
disorder in the world. Those at highest risk of iron deficiency include children, pregnant women,
infants, women with heavy menstrual cycles, and individuals that have cancer or gastrointestinal
disorders (especially those that cause bleeding) (Short, 2013).
Concerns
Individuals with low iron stores may not show specific signs at first. However, over time and
after development of iron deficiency anemia, individuals may experience a variety of symptoms.
Symptoms include inability to concentrate, being tired or weak, difficulty with physical activity,
inability to regulate body temperature, and they may have a hard time fighting off infection.
Learning difficulties like short attention span may develop in children with iron deficiency
anemia (NIH- Iron, 2022).
Iron Recommendations
In food, iron comes in two different forms: heme iron and non-heme iron. Heme iron is found in
foods that also contain the meat or blood of the animal. This form of iron is absorbed at a higher
rate than the other form of iron, which is referred to as non-heme iron. This type of iron is found
in plants, fortified foods and supplements. Some food sources of heme and non-heme sources of
iron are listed below:
Ham Kale
Chicken Nuts
Sardines Figs
Table 2: Iron Rich Food Sources (American Red Cross, 2023)
The absorption of non-heme iron can be increased by eating it with a food source of vitamin C,
which is commonly found in many citrus fruits like oranges.
An interesting way that is being explored to increase iron intake around the world I the use of a
product called the Lucky Iron Fish. The World Health Organization reports that 40% of pregnant
women are iron deficient (WHO-Anaemia,n.d.). Despite global efforts to provide iron
supplements and fortify foods with iron, the incidence of iron deficiency anemia continues to be
significant. The Lucky Iron Fish is a novel approach to improve iron status. The lucky iron
fish is a reusable cooking utensil made of ferrous iron that adds extra iron to meals. When added
during the preparation of liquid meals, a small but significant amount of iron will release into the
liquid as it is boiled. It has proven to be an effective way to reduce iron deficiency. It is
estimated that regular use of the lucky iron fish in cooking can provide up to 75% of the iron
needs a woman in her reproductive years has. The principle is the same as cooking with cast
iron cookware, but the Lucky Iron Fish is convenient to use and more accessible to the
populations in underdeveloped countries that are at high risk for deficiency (Principles of
Nutrition, BYUI).
What type of foods would increase the release of the iron into the food?
Is this heme or non-heme iron?
How could you increase the absorption of this type of iron?

Iodine
Iodine is a mineral and is used to make thyroid hormones which regulate basal metabolism,
growth, and development. The thyroid gland is located on the front of the neck just below the
Adam’s apple and in front of the trachea (windpipe). When dietary iodine is consumed, the
majority is in the thyroid gland. Seventy to eighty percent of the iodine in a human body is
concentrated within the thyroid gland. Iodine is also used to help build strong bones and to help
the developing brain of a baby while a woman is pregnant (Farhana, A. and Ganie, S.A, 2010).
Who is at risk?
Individuals that may be at highest risk of a deficiency include:
Pregnant women.
People who do not use iodized salt.
People who follow a vegan intake or eat a minimal amount of dairy, seafoods and eggs.
People who eat mostly local foods in areas where the soil is very low in Iodine. Most of
these regions are in the mountains, such as near the Andes, Himalayas and the Alps.
(NIH-Iodine, 2022)
Concerns
A diet that does not provide enough iodine in a pregnant woman may harm the fetus by impairing
its growth, intellectual development, and sexual maturation. A deficiency of iodine can also cause
issues with metabolism related to the thyroid, referred to hypothyroidism, as well as the
development of an enlarged thyroid which is called a goiter (Farhana, A. and Ganie, S.A, 2010)
(NIH-Iodine, 2022).
Iodine Recommendations
There are only a few foods that have a naturally significant amount of iodine. It is recommended
that you include a variety of those foods in your diet. Recommended foods include:
Cod Milk
Tuna Yogurt
Seaweed Cheese
Shrimp Eggs
Iodized salt – Processed foods, such as canned foods, although high in salt, is usually not
prepared with iodized salt. Other types of salt such as sea salt, kosher salt and Himalayan salt
are also usually NOT iodized.
Calcium
Calcium is a mineral that is needed in the diet whose main function is to support bone health. The
majority of calcium in the human body is in the bones. Strong, healthy bones provide structure to
the body and allow individuals to move safely. A small amount of calcium is in the body fluids.
Calcium in the body fluids has several key bodily functions such as blood clotting and muscle
contraction. It needs to be maintained for proper body function (Principles of Nutrition, 2022).
Who is at risk?
Because calcium is such an important mineral in creating healthy bone, those that are at risk of
not having adequate intake include the following:
Children and teens
Black or Asian individuals tend to have lower intake
Adults aged 50 and older, especially if they have a low economic income (NIH-Calcium,
2022)
Concerns
A low intake, or deficiency, of calcium can have a serious impact on bone health. The constant
need for the body to supply calcium to the fluids results in low bone calcium because the body
will remove calcium from the bones to maintain the calcium in the fluids. When this occurs over
time, the body develops weak bones. This condition is referred to as osteoporosis. This condition
is usually not a concern until later in life. If children or adolescents do not consume an adequate
amount of calcium they may end up with weaker bones and be at higher risk of osteoporosis as
they get older (Principles of Nutrition, 2022). Generally, women are at higher risk for
osteoporosis than men. Women typically have a lower calcium intake, smaller bones on average,
and their bone mass can be significantly impacted during menopause.
Calcium Recommendations
Calcium is found in many foods, and you can get an adequate amount of calcium by eating a
variety of foods from different food groups.
Dairy Non-dairy
Cheese Kale
Bok choi
Fortified juices
Fortified cereals
Vitamin D
Vitamin D is a fat-soluble vitamin. It is not found in a lot of foods, which can make meeting the
recommendation for vitamin D difficult. The human body can also make Vitamin D when the
skin is exposed to the sun’s ultraviolet B (UVB) rays. Although the body can produce some
vitamin D, it is not enough, so it is important to consume this nutrient in food or supplement
form. Vitamin D helps our body absorb the calcium we consume which makes it important for the
development and maintenance of strong bones. Other reasons Vitamin D is important is because
it helps our nerves carry messages in our body, regulates inflammation, and helps our bodies fight
infections (NIH - Vitamin D Health Professionals - 2022).
Who is at risk?
Several groups of people are at higher risk of getting a vitamin D deficiency. Those groups of
people include the following:
Individuals who stay home or are homebound. If you remain home or indoors, the time
spent in the sun when your skin can synthesize vitamin D is limited.
Individuals with darker skin don’t synthesize as much vitamin D as individuals with fair
skin.
People over age 65 don’t make as much vitamin D because the skin’s ability to make
vitamin D decreases as you age.
Individuals who spend time outside but cover their skin with clothing are at a higher risk
because their sun exposure is limited.
Breastfed infants are also at high risk of vitamin D deficiency. The amount of vitamin D
passed through in breastmilk is not sufficient to meet the needs of an infant. Vitamin D
supplements are recommended.
Obese individuals.
Living in Northern latitudes during the winter.
(NIH - Vitamin D- Consumer, 2022)
Concerns
Vitamin D deficiency can lead to the development of other diseases such as rickets in children
and osteomalacia in adults. Rickets is a rare disease that causes the bones to be very soft and to
bend which causes “bowing” of the legs. Osteomalacia in adults is also a condition of soft bones
which causes weak bones, bone pain and weakness.
There also is a possible connection between inadequate levels of vitamin D and other disease
such as high blood pressure, diabetes, cancer and depression. (NIH - Vitamin D - Consumer,
2022)
Vitamin D Recommendations
Since our body can synthesize vitamin D, one recommendation is to spend time outside in the
sunshine. Your body cannot produce too much vitamin D from sun exposure, however extended
time in the sun can put you at risk of skin cancer. Dietary intake is important and vitamin D
supplementation may be required, if available, to help meet the needs of the body. High levels of
vitamin D consumption can be harmful from food or supplements (Cleveland Clinic - Vitamin D,
2022)

health, 2023; Yuyan et al, 2022)
Energy (Calories) and Protein
Food that we eat provides calories and we use those calories to produce energy for our bodies.
Individuals who have a low intake of calories are at high nutritional risk, meaning they could
experience several conditions related to a poor dietary intake. If adequate calories are not
available, that most likely means there is an inadequate amount of protein available as well. There
are two specific protein malnutrition diseases: marasmus, and kwashiorkor.
Marasmus comes from a Greek word meaning “withering” or “to waste away.” Marasmus is a
severe deficiency of both protein and calories over an extended period of time. Extended
marasmus leads to starvation. Signs of marasmus include being severely underweight and wasting
appearance, loss of muscle and fat. Marasmus does not cause edema, or swelling tissues
(Cleveland Clinic, Marasmus, 2022).
Kwashiorkor comes from the language of Ghana. It means “disease of deposed child.” Deposed
child refers to a child who is no longer being breastfed because of the birth of a new baby. In
place of breast milk, the child is fed a watery, low protein, but adequate calorie porridge made
from grain. Kwashiorkor is caused by a deficiency in dietary protein. It is characterized by
swelling (edema) of the feet and abdomen, poor skin health, growth retardation, low muscle
mass, and liver malfunction. One of the classic signs of kwashiorkor is a swollen belly that can be
attributed to either a build-up of fluid in the abdomen, or an enlarged, or fatty, liver. In
kwashiorkor, the child does not appear dramatically thin because enough calories are consumed
to prevent muscle wasting (Cleveland Clinic, Kwashiorkor, 2022).
Who is at risk?
Individuals at highest risk of energy and protein malnutrition include women, infants, children
and adolescents. Low income or poverty increases the risk of malnutrition and magnifies the risks
from malnutrition (WHO, Malnutrition, 2020). Infants, whose calorie needs are high to support
their proper growth are at increased risk and those in developing countries are at an even higher
risk. In these areas, problems such as poverty, parasites, and infectious diseases increase calorie
needs and contribute to food scarcity and make this condition more common. Those at risk of
kwashiorkor are breastfed toddlers who are quickly weaned when a new baby is born and begins
breastfeeding. They transition to a high carbohydrate diet that lacks adequate amounts of protein
(Cleveland Clinic, Kwashiorkor, 2022). Specific conditions put people at risk such as wasting
diseases like AIDS and some cancers.
Areas of the world at high risk for protein and energy malnutrition include poorer areas of Africa,
Central America and Southeast Asia. Dietary intake in these areas is typically high in
carbohydrates which increases the risk of poor protein intake. Environmental factors, such as
famine, war and natural disasters which impact the food supply for a population, also increase the
risk of these deficiencies (Cleveland Clinic, Kwashiorkor, 2022).
Concerns
Malnutrition, in one form or another, affects all countries around the globe. Battling malnutrition
is one of the biggest health challenges in the world. Undernutrition, especially from calories and
protein, can cause several disruptions in the body. The body may experience low blood sugars,
suppressed immunity resulting in increased risk of infection and illness, low body temperature,
growth and developmental delays in children and eventually starvation can occur. In situations
where starvation exists, the body's fat and muscle are used to provide energy instead of other key
functions. The heartbeat slows, and blood pressure and temperature both drop. Parts of the
digestive tract can stop working. Inadequate intake of calories can result in death (Cleveland
Clinic - malnutrition, 2022).
Calorie/Protein recommendations
Beginning to feed someone that has experienced severe energy malnutrition needs to be
approached carefully and may require medical attention depending on the severity of the
condition. If they have been suffering from starvation for a significant amount of time, there are
several things that need to be addressed before they can begin eating. They need to be rehydrated
with fluids and micronutrients to help stabilize their body before they can begin eating food. They
must also be kept warm and treated for any infections. After they are stable, the individual can
start to be refed, which starts slowly and usually with liquid supplements. Calories will start low
and then be increased above their recommended intake to make up for delayed growth in
children. This may last several weeks. These individuals should be monitored and receive follow-
up care. If a person has been facing hunger from a temporary lack of food resources, then
providing the needed energy and protein can be addressed quickly (Cleveland Clinic,
Kwashiorkor, 2022; Cleveland Clinic, Marasmus, 2022).
In situations where war, economic issues, weather extremes or other factors cause a scarcity of
food leading to severe acute weight loss and malnourishment, a variety of ready to use
therapeutic foods (RUTF’s) are available. Aid agencies such as the World Food Program and
UNICEF utilize these products when providing emergency aid. One of the most widely used
RUTF products is called Plumpy’nut. It is a shelf stable paste made of peanut butter fortified
with protein and other added nutrients. It is most often used to help malnourished children.
Feeding someone in this type of situation has to be done with care. In cases of extreme
malnourishment, feeding too aggressively can be deadly. The rush of food into the system can
cause shifts in already strained blood electrolyte levels leading to cardiac arrest. This is termed
“Refeeding Syndrome” (Principles of Nutrition, 2022).

The best thing to do is work towards solutions that can prevent these types of conditions from
occurring.
The continued use of unsustainable agricultural practices in some places: A wide variety of
unwise agricultural practices can lead to a long-term impact on food availability. Some examples
include the following:
Loss of topsoil: Maintaining adequate, well-nourished topsoil is critical. Developing a productive
depth of topsoil can take decades, and without proper care, that topsoil can be lost in mere days
through wind and water erosion. Deforestation continues in many places in the world and can be a
significant contributor to soil erosion. Compaction of topsoil by heavy machinery and even foot
traffic can damage topsoil. Contamination of soils with toxic chemicals continues to be a problem
in many places. Poor crop rotation and unwise use of fertilizers can also impact soil
quality. Topsoil needs to be managed well or conserved to preserve a people’s or nation’s ability
to produce their own food.
Reduction of crop diversity: Small farms produce the majority of the food in the world, they are
especially important in developing countries. As more and more of our food production moves to
larger scale production farms, there is a risk that crop variety will decrease. Reliance on only a
few crops may lead to food shortages if a failure of any one of the crops occurs. The Irish potato
famine offers an example of when this happened. In the 1800s, potatoes were a staple food for
most people in Ireland. The farmers primarily produced one type of potato. A disease called late
blight swept through the soil in Ireland destroying potato crops. Many people died of hunger or
were displaced. New disease-resistant varieties became available that helped people plant potato
crops again in Ireland. This demonstrates the danger of relying too heavily on a single crop as a
source of food.
Uneven distribution of agricultural knowledge and technology: In the last 100 years, advances in
agricultural knowledge and technology have increased exponentially. The result is increasing
food production in many places through improved agricultural management, fertilization, and
pest control. Due to a variety of reasons, access, and utilization of these advances in technology
and improved agricultural techniques have not been utilized in many areas of the world that most
desperately need it.
More people are needed around the world that are well educated in sustainable agricultural
techniques.
Global climate change – Weather patterns continue to change globally, impacting food
production. Alternately, drought and flooding regularly devastate food production capacity
around the world.
Food choices– A lack of understanding about the long-term implications of food choices can be
detrimental to our food security. This can be from a lack of education or from competing
priorities and poor planning. For example, as countries grow economically, they typically move
from a plant-based to an increasingly animal-based diet. Meat consumption can require more
resources to produce the same calories, protein, vitamins and minerals than grains, legumes,
fruits, or vegetable crops.
Government policies – Government policies can dramatically affect the commodity markets and
influence what crops are grown, what are subsidized, what is imported and exported, how crop
damages are handled, and many more aspects of large-scale food production. This can impact the
ability of food to get into the hands of those who need it most. For example, the Irish Potato
Famine of the 1840s was impacted by British policies. When a fungus destroyed the Irish potato
crops many people died from starvation as it was their only food source. Policies put in place by
the British government directed food sources, like wheat crops, be moved out of Ireland. These
sources could have been used to relieve hunger.
Political instability and conflict – Warfare is the number one cause of food insecurity and
hunger. Wars continue to rage worldwide. In section 89 verse 4 of the Doctrine and Covenants,
the Lord tells us that the Word of Wisdom is given to warn us "in consequence of evils and
designs which do and will exist in the hearts of conspiring men in the last days. " We see this in
the instance of wars that displace people from their homes and homelands, inhibit food
production, and result in loss of crops and the ability of food supply chains to distribute food.
Food deserts – In developed countries, urban growth and/or inadequate community planning can
result in food deserts. A food desert is anywhere people have limited access to affordable and
healthy food. They commonly occur in low income urban or rural areas and are often due to a
combination of inadequate access to transportation and long distances to the closest grocery store
(or other facility that provides access to affordable healthy foods such as fruits, vegetables and
dairy products). Individuals living in these areas often turn to fast food, convenience store foods,
or other less optimal food sources that are high in calories and nutrient poor. This often
contributes to hidden hunger and the double burden of malnutrition.
Food waste – The United Nations reports that 14% of the world’s food is lost annually while
moving from the field to the market, another 17% is wasted at home or in the markets. (FOA,
2023). Together this accounts for roughly 1/3 of the food produced.
2. Science
Increased crop production: Advances in agricultural technology have been increasing the
amount of food produced on a given amount of land. In the last 150 years, the amount of corn that
could be produced on an acre of land has risen from around 20 bushels/acre in the mid 1800s to
around 200 bushels per acre by 2020. This increase production was largely accomplished by
advances in planting and harvesting machinery, plant breeding, better pest control, improved
irrigation, and fertilization. For example, 150 years ago, crops in the United States were primarily
planted and harvested by hand and rainwater was relied upon for crop production. In most
developed nations today, seeds are planted by large machinery that can sow and fertilize large
fields in a fraction of the time. Sophisticated irrigation systems can sense the water needs of
plants and adjust the rate of water delivery based on need. Selective breeding of plants has
resulted in the development of large and faster producing crop varieties that can flourish in a wide
variety of conditions.
As these technologies continue to advance and to become more economically feasible and
accessible in developing nations, food production can continue to increase. Over 70% of the food
produced in the world is produced on small farms, mostly in developing countries. Helping small
farms increase food production, in a sustainable way, is an important piece to the solution for
hunger. Developing new land for crop production is an unlikely strategy to help feed the world.
Farmers will need to be able to produce more crops on the land they have or less land.
Look in the community where you live. What are advances that could be made in your
community that could increase food production? Small changes initiated now could be the means
of blessing future generations.
Increased animal production: Advances in animal production are similar to those described
with plant production. Around 70 years ago, the average broiler chicken weighed about 2 pounds
at maturity. In the early 2000’s the same chicken weighed roughly 9 pounds. Over a similar
period of time, the average weight of a beef cow went from 650 pounds to 900 pounds. Advances
in breeding (selective breeding), nutritional care, management, and health care of the animals
have been primarily responsible for these advances.
Genetically modified organism (GMO): Selective breeding of plants and animals has been a
very effective strategy to increase the production of plant and animal foods but is imprecise and
can take many generations before improvement is noted. Genetic modification of plants and
animals can target changes in specific genes in a precise way. It can be used to increase plant and
animal production, increase nutritional quality of food products, or make them more resistant to
extreme environments. GMO’s have been viewed suspiciously in many places. The safety and
usefulness of GMO’s should not be judged globally but needs to be assessed on a case-by-case
basis. Of course, there are certain specific types of GMO’s that, if handled unwisely, could be
potentially harmful. However, in most cases the genetic modifications made through genetic
engineering can certainly be a safe tool used in the global battle against hunger (WHO: Food-
Genetically Modified, 2014).
Food waste that occurs from the farm to the market can be a more difficult problem to manage.
Long distances between farms and markets on rough roads make it difficult to get food to where
they can be sold before they are damaged or spoiled. This involves larger scale operations to
improve roads and infrastructure and the ability to bring people and the markets together more
easily.
Advanced technology that improves refrigeration and opens the door to some food processing and
preservation can have a huge impact on food waste. Food processing can improve the stability of
the food for transport and storage. It can also be used to improve the nutrient value of foods
through enrichment and fortification (adding in vitamins and minerals). If done correctly, food
preservation techniques like drying, bottling, and pickling can be a safe way to decrease waste
and increase the availability of perishable foods.
4. Education
Certainly, if healthy food choices are not easily accessible, education on how to select healthy
foods may just be frustrating. But in most cases, healthy food choices are available, but a lack of
knowledge impedes good choices. An educated set of consumers can also drive food production:
if healthy food is demanded, food producers will find a way to provide them. Having a healthy
sustainable food supply depends on consumers making wise choices and what the farmers select
to grow.
5. Willingness to change
Food events and traditions knit families, communities, and populations together. Having this
cultural and family identity is important in having a sense of belonging. However, some food
traditions may carry with them consequences that put us at risk for undernutrition. When our
food traditions put us at risk nutritionally, we must be willing to mold and adapt them.
Highly processed, nutrient-poor foods that are easily accessed, inexpensive, and cleverly marked
are becoming more and more available. If they become the center of a person’s diet, they can
contribute to forms of undernutrition (such as sub-clinical deficiencies) even though caloric
intake may be sufficient. A wiliness to manage these types of highly palatable foods is important
for long term health.
In 2011 a severe drought led to a food crisis that turned into a severe famine largely due to
political unrest leading to war. War reduces crop production and hampers food supply chains and
the ability of aid to be provided. Corruption in high positions additionally decreased the ability of
food to get to those most in need, turning a bad situation into a disaster. As the gospel continues
to move forth and becomes more deeply etched in our hearts, peaceful solutions can be more
readily sought, and the welfare of others will be given priority over personal gain (Maxwell and
Fitzpatrick, 2012).
“If any man shall take of the abundance which I have made, and impart not his portion, according
to the law of my gospel, unto the poor and the needy, he shall, with the wicked, lift up his eyes in
hell, being in torment” (D&C 104:18).
3.5 Overnutrition and Chronic Disease
Overnutrition may manifest itself in several different forms. Excessive nutrient intake from
supplementation or fortified foods may lead to toxicities of some vitamins and minerals. Despite
how devastating this type of overconsumption can be when it occurs, the magnitude of the public
health concern from excess intake of vitamins and minerals is small in comparison to the concern
of the over consumption of calorie rich, nutrient poor food that is becoming common throughout
the world. This type of “malnutrition” is a contributor to chronic diseases such as
overweight/obesity, heart disease and stroke, type 2 diabetes, hypertension, and some cancers.
Many of the health problems of modern society could be minimized by simply addressing poor
diet choices. Cancer and heart disease account for over 40% of the total deaths in the US. Both
diseases have a strong relationship to dietary habits.
Globally, other high-income countries display a similar disease pattern as the United States
(WHO, Top Ten causes of death, 2020). The rate of chronic diseases, like heart disease and
stroke, are increasing in low-income countries as well, but the highest percentage of deaths are
still related to infectious disease such as respiratory and diarrheal disease and neonatal deaths.
This can be attributed to factors such as higher rates of undernutrition, lack of access to
healthcare, and limited sanitation services.
Table 1: Leading causes of death globally in high income and low-income countries (listed from
highest to lowest (WHO, 2020).
Types of Fats
Some tips for reducing saturated fat when dietary intake is high (WHO-
Healthy Diet, 2022):
Steaming or boiling instead of frying in saturated fat
Read food labels and learn to identify foods high in saturated fats
Replace butter, lard, and ghee with oils such as olive oil, canola oil, corn oil or sunflower
oil
Consuming low-fat, instead of full fat, dairy products
Choose lean proteins and trimming visible fat from meat
Replace some animal proteins with plant proteins such as beans, legumes and lentils
The recommendation to keep saturated fats to <10% of total Calories can be calculated for an
individual’s daily intake using a person’s calorie recommendation. See below for examples:
Example 1:
Sam’s estimated caloric recommendation is 2300 Calories/day. What is the limit of saturated fats
in his diet in Calories and grams?
2300 Calories x 10% (.10) = 230 Calories/day
230 Calories / 9 kcal/gram = 25.5 (rounds up to 26) so 26 grams/day
Example 2:
Ingrid’s estimated caloric recommendations is 1870 Calories/day. What is the limit of saturated
fats in her diet in Calories and grams?
1870 Calories x 10% (.10) = 187 Calories/day
187/ 9 kcal/gram = 20.7 (rounds up to 21) so 21 grams/day
If food labels are available, they can often be used to determine if foods are high in total fat or
saturated fats.
Low saturated fat 1.5 grams or less per 100 grams of food
Example 1:
Kai’s estimated caloric recommendation is 2820 Calories/day. What is the limit of added sugars
in his diet in Calories and grams?
2820 Calories x 10% (.10) = 282 Calories/day
282 Calories / 4 kcal/gram = 70.5 (rounds up to 71) so 71 grams/day
Examples 2:
Natalia’s estimated caloric recommendation is 2110 Calories/day. What is the limit of added
sugars in her diet in Calories and grams?
2110 Calories x 10% (.10) = 211 Calories/day
211 Calories / 4 kcal/gram = 52.75 (rounds up to 53) so 53 grams/day
You can often identify whole grain products by the food labels. Labels may say 100% whole
grain, or list “whole” grain flour as the first ingredient in an ingredient’s list such as “whole
wheat flour." Grains provide energy and nutrients for our body. Most countries that have
published recommendations on grain intake encourage intake of whole grains to be at least one-
third of their intake up to more than half of their intake.
Quinoa Oatmeal
Teff Amaranth
Fruits/Vegetables (Increase)
Most people struggle to consume adequate amounts of fruit and vegetables. Fruits and vegetables
are low in calories and high in vitamins and minerals, which makes them nutrient dense. These
foods increase our intake of fiber and nutrients that are protective against chronic disease. In
general, a diet high in fruits, vegetables, nuts, seeds, and whole grains is associated with a
reduced risk of cardiovascular disease and many other diseases.
Tips to include more fruits and vegetables include (WHO -Healthy Diet,
2022):
Eat a vegetable with meals.
Eat fresh fruits and vegetables as snacks.
Choose fruits and vegetables that are in season.
Plant a garden if able and use fruits and vegetables that you grow.
Eat a variety of fruits and vegetables.
Underweight Less than the 5th percentile Less than 18.5 kg/m2
Overweight/Obesity Concerns
An elevated BMI puts individuals at higher risk of other chronic (noncommunicable) diseases
such as heart disease, diabetes, osteoarthritis and certain cancers. Children have additional risks
such as breathing issues, premature death and disability in adulthood, as well as development of
chronic disease at earlier ages.
Overweight/Obesity Recommendations
In most instances, overweight and obesity are preventable. Small changes in diet and physical
activity can impact the health of an individual and can increase health.
Heart Disease/Stroke
Heart disease is a group of disorders of the heart and blood vessels. There are several diseases
that fall under the term heart disease. A detailed description of the different types of heart disease
will not be included in this text, but generally they are associated with the vessels that are
affected. For example, stroke and heart attacks are the result of a blockage of a vessel leading to
the brain or heart respectively. The blockage of a vessel is typically referred to as plaque. Plaque
is the collection of fatty substances and other cellular debris under the lining of the blood vessels
that if left unchecked can grow to the point it will restrict blood flow and increase the workload
of the heart.
Low intake of whole grains High waist circumference (men > 40 inches,
women > 35 inches)
Blood pressure
High blood pressure can promote plaque development as well as be an indication of the existence
of plaques in the blood vessels.
For those that can have their blood pressure taken, it measures the pressure of the blood vessels at
work and at rest. The top number is referred to as systolic pressure and the bottom number is
referred to diastolic pressure. An example of a blood pressure would be 118/78, which is read
“118 over 78”. This would be considered a healthy blood pressure. See table below to assess
blood pressure.
Blood Cholesterol
An in-depth discussion of blood cholesterol is beyond the scope of this text. In brief, fat and
cholesterol are transported around the body in the blood. Fat and cholesterol are needed by the
cells for a variety of essential functions. They are often transported inside carriers to help move
efficiently in the blood. Two important carriers are low density lipoproteins (LDL) and high-
density lipoproteins (HDL). Both carry out very important functions, but when levels become
imbalanced, they can contribute to the development of heart disease. The table below lists the
basic role of these two carriers as well as normal blood levels. Normal levels for total cholesterol
and triglyceride are also listed.
Low Density Lipoprotein Delivers cholesterol and fat Optimal if below 100 mg/dl
(LDL) to cells. It serves a good
function but if to high it can
lead heart disease.
Total Cholesterol High levels are associated Less than 200 mg/dl
with cardiovascular disease.
Recommendations to help reduce the risk of heart disease, strokes and heart attacks are aimed at
preventing and managing high blood pressure and cholesterol levels.
Replace saturated fat intake with unsaturated fats, especially polyunsaturated fats
Type 2 Diabetes
Type 2 diabetes is a chronic disease that results from the body’s inability to use insulin
effectively. Insulin is a hormone that helps the body manage blood sugar. When the body is
unable to use blood sugar correctly, the blood sugar becomes elevated. Type 2 diabetes is related
to excess body weight and being physically inactive.

Cancer
Cancer is caused by uncontrolled division of some body cells that can then spread to other parts
of the body (NCI, 2021). Cancer can start almost anywhere in the body. While some cancers have
a clear genetic connection, there are other cancers that are linked strongly to diet. Types of cancer
that have known relationships to diet include breast, colorectal, endometrial, stomach and mouth
cancers.
Low fruit and vegetable intake Nitrosamines, burnt and charred foods
Cancer Concerns
It is estimated that the percentage of cancers that could be prevented by modifying dietary intake
and other unhealthy lifestyle choices is about 30-50%. Cancer accounts for a large loss of life and
can be prevented if detected early and treated.
Cancer Recommendations
Among the recommendations such as avoiding ultraviolet radiation exposure, getting vaccinated
against viruses, and reducing exposure to chemical carcinogens, there are several
recommendations that include modifying nutrition and activity choices.
Consume a plant-based diet including lean proteins from plants such as beans and
legumes
