When oxygen is metabolized (this process is called ‘oxidation’), it creates ‘free radicals’ (chemicals without paired electrons).
Free radicals damage cell membranes and other structures. What do they do? Free radicals steal electrons from other molecules. This causes damage to cell membranes and other structures. The body can cope with a certain amount of free radicals (and actually need some in order to function properly).
However, stress, cigarette smoking, alcohol, sunlight, pollution and other factors of modern living can accelerate the process of oxidation.
A large amount of free radicals in the body has been linked to certain diseases, including heart disease and some cancers. b) What are antioxidants? Antioxidants are compounds found in certain foods that neutralise free radicals. These compounds include the vitamins A, C and E, and the minerals copper, zinc and selenium. Other compounds, such as the phytochemicals in plants and zoo chemicals from animal products, are believed to have greater antioxidant effects than either vitamins or minerals. What do they do? A diet high in antioxidants may reduce the risk of many diseases, including heart disease and certain cancers. Antioxidants scavenge the free radicals from the body cells, and prevent or reduce the damage caused by oxidation.

Flavonoids, found in green tea, are believed to contribute to the low rates of heart disease in Japan.
