The energy which is provided by food is in the form of three kinds of chemical substances. They are carbohydrate, protein and fat. Carbohydrate provides 8.8 calories per gram (cal/gm) of energy, protein 4.0 cal/gm and fat 8.0 cal/gm. Each food contains different proportion of these substances.These three chemical substances are all important for body staying healthy.
