,The Importance Of Various Dietary Components
Dietary components called, nutrients are the necessary
constituents of food required by organisms for growth
and the maintenance of life.
There are five classes of nutrients that contribute to an
adequate diet.
These may be divided into: Macronutrients and
micronutrients.

main bulk of food. In the Indian dietary pattern, they
contribute to the total energy intake in the following
proportions:
Proteins 7 to 15%
Fats 35 to 45%
Carbohydrates 50 to 70%
