What part does our food play?

Food acts in our bodies as petrol does in a car. But petrol only makes a car go, does not mend a car or replace worn out parts. Food, on the other hand, not only gives us the energy to live and grow, it also provides substances to prevent illness, cure disease and keep our body temperature constant. Although different people all over the world eat different things, the same basic food substances are necessary to all if they are to stay healthy. These are: proteins, carbohydrates, fats and minerals. In addition, there are the vitamins. An Eskimos eats a differnt diet from an Arab, and an American’s meal is not at all like that of a Chinese. But all of them depend on they same basic food substances so that the differences are not so very great.
