Antioxidants
What are they?
Chemical reactions within the body produce oxidants (free radicals), which are believed to contribute to a number of health problems such as cancer, tissue damage and premature aging. Antioxidants (or anti-oxidation agents) can reduce the effect of oxidants by binding together with these molecules, decreasing their destructive power. Antioxidants can also help repair damage already sustained by cells. Certain antioxidant enzymes are believed to be produced within the body, while others we must get from our diet.
What foods contain antioxidants?
Antioxidant agents can be found in many foods. Items high in vitamin A, vitamin C, vitamin E, and beta-carotene, commonly found in dark green leafy vegetables and fruits, are believed to be the most beneficial. There is also a higher concentration of antioxidants in raw fruits and vegetables rather than cooked.
Dietary supplements are also available for those who do not consume enough antioxidant foods.
