Abstract

The food-stuffs that we consume should contain the right amount and kind of proteins, fats, carbohydrates, vitamins and mineral salts, if we are to live in normal health and our body is to function properly. Each of these ingredients supplies some requirement or other of the body complex. Proteins are necessary for building the muscles; carbo- hydrates are the body's chief source of energy; fat is the heat producer while mineral salts and vitamins play an important part in the physiological functions. Any one food-stuff that is available to man may not contain all the above ingredients, so that by consuming one particular product we can- not supply the full requirements of the body. Therefore, we must combine them judiciously so that our daily diet contains all these essential ingredi- ents in the right proportions.
