DISEASES AND DISABILITIES DUE TO FOOD Diseases Due to Deficiency of
DEFICIENCIES
A healthy and balanced diet, enriched with
all the essen al nutrients, is a must for
overall well-being’. Children and adults alike
require proper nutri on for ensuring a
healthy and long life. Malnutri on and
deficiency of these vital elements can lead
to serious diseases and condi ons.
Diseases caused due to the deficiency of
nutrients are called deficiency diseases.
Let’s discuss about some deficiency
diseases:
Deficiency of Carbohydrates
Carbohydrates are the main source of
energy required by our body. Most of the
cereals specially rice and wheat, sugar and
jaggery and potatoes are the main food
items rich in carbohydrates.
Let’s see daily average energy requirements
of various age groups:

The above men oned energy requirements
may vary on the basis of the occupa on and
age of the people.

Carbohydrates and Proteins
Due to the deficiency of carbohydrates, our
body does not get the required amount of
energy that leads to weakness in body and
loss of stamina.
Deficiency of proteins may hamper proper
body growth. Children become the vic m of
protein deficiency disease very easily.
Inadequate supply of proteins and energy
leads to Protein Caloric Malnutri on (PCM)
which may cause the following diseases.
Kwashiorkor
Kwashiorkor is a deficiency disease caused
by lack of protein and energy in the body. It
is characterised by anorexia, an enlarged
liver, irritability and ulcera ng dermatoses.
These are the one of the nutri onal
deficiencies in children, especially from
famine-struck areas and places with poor
food supply, Kwashiokor is caused by
malnutri on. A healthy and balanced diet
