Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing. These elements are called “vitamins”. Quite a number of such substances are known and they are given letters to identify them, A,B,C,D, and so on. Different diseases are associated with deficiencies of particular vitamins.
