All the world’s health advisory bodies agree that antioxidants are part of the body’s vital self-protection mechanism which actually defend you against 60 or more diseases, including the big killers of heart disease and cancer. They were almost unknown until comparatively recently and knowledge is still growing.

The three big saviours are vitamins – the beta-carotene form of vitamin A, vitamin C and vitamin E. None of them is found abundantly in meat, but the number of different plant foods which contain them is enormous. A recent discovery has added another powerful group of antioxidants to the list – flavonoids. They, too, are not found in meat but in predominantly red, purple or black fruit and vegetables.
