Malnutrition
Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth
and development falter and the risk of
infection and nutritional disorders
increases.
Protein-Energy Malnutrition (PEM)
A lack of energy – derived mainly from
carbohydrates – results in undernutrition.
A lack of proteins, vitamins and minerals
leads to malnutrition.
All too often people lack both proteins and
carbohydrates.
Protein-Energy Malnutrition (PEM)
The result is PEM,
which has it greatest
impact on the young
and if the mother is
malnourished, on the
developing foetus.
Protein-Energy Malnutrition (PEM)
PEM is characterised
by low birth weight
(2.5kg or less), poor
growth (too short, too
thin) and high levels
of mortality in young
children, especially
between 12 and 24
months.
Underweight Children
Nearly 13 million children under five years
old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness
of the body’s immune
system.
A lack of fluoride is
associated with
increased levels of
dental caries.
Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide
range of chronic diseases such as
coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent
among the urban populations who often
have an imbalanced diet and too little
exercise.
Chronic diseases may also result from
exposure to food-borne pathogens or
food-borne toxic chemicals.

Malnutrition
Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth
and development falter and the risk of
infection and nutritional disorders
increases.
Protein-Energy Malnutrition (PEM)
A lack of energy – derived mainly from
carbohydrates – results in undernutrition.
A lack of proteins, vitamins and minerals
leads to malnutrition.
All too often people lack both proteins and
carbohydrates.
Protein-Energy Malnutrition (PEM)
The result is PEM,
which has it greatest
impact on the young
and if the mother is
malnourished, on the
developing foetus.
Protein-Energy Malnutrition (PEM)
PEM is characterised
by low birth weight
(2.5kg or less), poor
growth (too short, too
thin) and high levels
of mortality in young
children, especially
between 12 and 24
months.
Underweight Children
Nearly 13 million children under five years
old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness
of the body’s immune
system.
A lack of fluoride is
associated with
increased levels of
dental caries.
Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide
range of chronic diseases such as
coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent
among the urban populations who often
have an imbalanced diet and too little
exercise.
Chronic diseases may also result from
exposure to food-borne pathogens or
food-borne toxic chemicals.

Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth
and development falter and the risk of
infection and nutritional disorders
increases.
Protein-Energy Malnutrition (PEM)
A lack of energy – derived mainly from
carbohydrates – results in undernutrition.
A lack of proteins, vitamins and minerals
leads to malnutrition.
All too often people lack both proteins and
carbohydrates.
Protein-Energy Malnutrition (PEM)
The result is PEM,
which has it greatest
impact on the young
and if the mother is
malnourished, on the
developing foetus.
Protein-Energy Malnutrition (PEM)
PEM is characterised
by low birth weight
(2.5kg or less), poor
growth (too short, too
thin) and high levels
of mortality in young
children, especially
between 12 and 24
months.
Underweight Children
Nearly 13 million children under five years
old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness
of the body’s immune
system.
A lack of fluoride is
associated with
increased levels of
dental caries.
Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide
range of chronic diseases such as
coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent
among the urban populations who often
have an imbalanced diet and too little
exercise.
Chronic diseases may also result from
exposure to food-borne pathogens or
food-borne toxic chemicals.

A lack of proteins, vitamins and minerals
leads to malnutrition.
All too often people lack both proteins and
carbohydrates.
Protein-Energy Malnutrition (PEM)
The result is PEM,
which has it greatest
impact on the young
and if the mother is
malnourished, on the
developing foetus.
Protein-Energy Malnutrition (PEM)
PEM is characterised
by low birth weight
(2.5kg or less), poor
growth (too short, too
thin) and high levels
of mortality in young
children, especially
between 12 and 24
months.
Underweight Children
Nearly 13 million children under five years
old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness
of the body’s immune
system.
A lack of fluoride is
associated with
increased levels of
dental caries.
Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide
range of chronic diseases such as
coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent
among the urban populations who often
have an imbalanced diet and too little
exercise.
Chronic diseases may also result from
exposure to food-borne pathogens or
food-borne toxic chemicals.

Malnutrition
Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth

infection and nutritional disorders
increases.

old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness

A lack of fluoride is
associated with
increased levels of
dental caries.
Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide
range of chronic diseases such as
coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent
among the urban populations who often
have an imbalanced diet and too little

Malnutrition
Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth
and development falter and the risk of
infection and nutritional disorders
increases.
Protein-Energy Malnutrition (PEM)
A lack of energy – derived mainly from
carbohydrates – results in undernutrition.
A lack of proteins, vitamins and minerals
leads to malnutrition.

The result is PEM,
which has it greatest
impact on the young

Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide

coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent

Malnutrition
Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth
and development falter and the risk of
infection and nutritional disorders
increases.
Protein-Energy Malnutrition (PEM)
A lack of energy – derived mainly from
carbohydrates – results in undernutrition.
A lack of proteins, vitamins and minerals
leads to malnutrition.
All too often people lack both proteins and
carbohydrates.
Protein-Energy Malnutrition (PEM)
The result is PEM,
which has it greatest
impact on the young
and if the mother is
malnourished, on the
developing foetus.
Protein-Energy Malnutrition (PEM)
PEM is characterised
by low birth weight
(2.5kg or less), poor
growth (too short, too
thin) and high levels
of mortality in young
children, especially
between 12 and 24
months.
Underweight Children
Nearly 13 million children under five years
old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness

Malnutrition
Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth
and development falter and the risk of
infection and nutritional disorders
increases.
Protein-Energy Malnutrition (PEM)
A lack of energy – derived mainly from
carbohydrates – results in undernutrition.
A lack of proteins, vitamins and minerals
leads to malnutrition.
All too often people lack both proteins and
carbohydrates.
Protein-Energy Malnutrition (PEM)
The result is PEM,
which has it greatest
impact on the young
and if the mother is
malnourished, on the
developing foetus.
Protein-Energy Malnutrition (PEM)
PEM is characterised
by low birth weight
(2.5kg or less), poor
growth (too short, too
thin) and high levels
of mortality in young
children, especially
between 12 and 24
months.
Underweight Children
Nearly 13 million children under five years
old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness
of the body’s immune
system.
A lack of fluoride is
associated with
increased levels of
dental caries.
Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide
range of chronic diseases such as
coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent
among the urban populations who often
have an imbalanced diet and too little
exercise.
Chronic diseases may also result from
exposure to food-borne pathogens or
food-borne toxic chemicals.

Malnutrition
Malnutrition is not limited to the poor nor is
good nutrition a monopoly of the rich.
Well-being is determined by what people
eat, the way they live or are cared for and
how they react to their environment.
Preventing malnutrition must start with
satisfying the basic and changing
physiological needs of human beings from
before conception to old age.
A healthy diet includes minerals,
carbohydrates, fats and fatty acids,
proteins and vitamins.
When the intake and balance of these
essential nutrients are insufficient, growth
and development falter and the risk of
infection and nutritional disorders
increases.
Protein-Energy Malnutrition (PEM)
A lack of energy – derived mainly from
carbohydrates – results in undernutrition.
A lack of proteins, vitamins and minerals
leads to malnutrition.
All too often people lack both proteins and
carbohydrates.
Protein-Energy Malnutrition (PEM)
The result is PEM,
which has it greatest
impact on the young
and if the mother is
malnourished, on the
developing foetus.
Protein-Energy Malnutrition (PEM)
PEM is characterised
by low birth weight
(2.5kg or less), poor
growth (too short, too
thin) and high levels
of mortality in young
children, especially
between 12 and 24
months.
Underweight Children
Nearly 13 million children under five years
old die every year from infections and as a
direct or indirect result of hunger and
malnutrition.
Micronutrient-Deficiency Diseases
A lack of essential vitamins and minerals
such as calcium, iodine, iron and zinc
leads to micronutrient-deficiency diseases
or disorders.
Micronutrient-Deficiency Diseases
Blindness and death
can be caused by a
lack of vitamin A;
goitre and cretinism
by a shortages of
iodine; and anaemia
by insufficient iron
intake.
Micronutrient-Deficiency Diseases
More subtle impacts
of deficiencies include
reduced effectiveness
of the body’s immune
system.
A lack of fluoride is
associated with
increased levels of
dental caries.
Chronic Diet-Related Diseases
Diets high in energy and animal fat but low
in fibre, combined with unhealthy habits
and lifestyles, can contribute to a wide
range of chronic diseases such as
coronary heart disease, diabetes mellitus
and diet-related cancers.
They are found in all countries.
Chronic Diet-Related Diseases
In the Third World, they are prevalent
among the urban populations who often
have an imbalanced diet and too little
exercise.
Chronic diseases may also result from
exposure to food-borne pathogens or
food-borne toxic chemicals.
