The human body requires a wide range of minerals, vitamins and nutrients if it is to work efficiently. The problem is that no one seems to know exactly what they do, and how much of them we need.
People all over the world live full and healthy lives living on simple, unvaried and unsupplemented diets. However, some cultures have diets deficient in certain essential (Japan's population suffer a high incidence of rickets, a bone condition caused by lack of vitamin D).
I'm not a great lover of fish, or green vegetables. So I supplement my diet with a multi-vitamin tablet and a fish-oil capsule each day. I also know that the fruit I eat has often been chilled during its journey to Waitrose, weakening the vitamin C content. So I swallow a 500mg vitamin C tablet as well.
I have no idea if they do much good. But I do know that I'm getting a regular dosage of stuff that the experts tell me I need.
