Food we eat, has various functions:

• Body building

Foods rich in carbohydrates and fats are called energy yielding foods. They provide energy to sustain the
involuntary processes essential for continuance of life, to carry out various professional, household and
recreational activities and to convert food ingested into usable nutrients in the body. The energy needed is
supplied by the oxidation of foods consumed. Cereals, roots and tubers, dried fruits, oils, butter and ghee
are all good sources of energy. Foods rich in protein are called body building foods. Milk, meat, eggs and
fish are rich in proteins of high quality. Pulses and nuts are good sources of protein but the protein is not of
high quality. These foods help to maintain life and promote growth. They also supply energy. Foods rich in
protein, minerals and vitamins are known as protective and regulatory foods. They are essential for health
and regulate activities such as maintenance of body temperature, muscle contraction, control of water
balance, clotting of blood, removal of waste products from the body and maintaining heartbeat. Milk, egg, liver, fruits and vegetables are protective foods.
