    The Proximate principles present in the food are the proteins, carbohydrates, fats, vitamins, and minerals. The protein, carbohydrates & fats are known as macro nutrients (energy giving nutrients), which are required by the body in large amounts and the vitamins & minerals are considered as the micro nutrients, which are required by the body in less quantity.

    1. Carbohydrates: Carbohydrates provide maximum energy to our body. Therefore it is required in large amount.There are 3 types of carbohydrates is (1) sugars (also called simple carbohydrates), (2) starches (also called complex carbohydrates), and (3) fiber. Except fiber & starch only carbohydrates cause more & faster blood glucose rises than the other macro nutrients. Carbohydrate is a instant & quick source of energy. The sources of carbohydrates are all cereals & cereals based products.
