Food security has several dimensions such as:
a) availability of food in the market, which is a function of production,
b) access to food which is a function of purchasing power and
c) absorption of food in the body which is a function of the availability of clean drinking water, sanitation, toilets, primary healthcare and nutritional literacy.
There are also three types of hunger, viz.
a) under-nutrition resulting from calorie deprivation
b) protein-hunger arising from inadequate consumption of protein-rich foods like pulses, milk, egg etc. and
c) hidden-hunger caused by the deficiency of micronutrients in the diet, such as iron, iodine, zinc, Vitamin A and Vitamin B12.
