According to the University of California at Berkeley Wellness Letter (11/06), only antioxidants found in food (not in supplements) "help deactivate the free radicals that damage cells and promote chronic diseases."
The American Journal of Clinical Nutrition listed the top 14 antioxidant foods and beverages based on typical serving sizes:
blackberries, walnuts, strawberries, artichokes, cranberries, brewed coffee, raspberries, pecans, blueberries, cloves, grape juice, unsweetened baking chocolate, sour cherries and red wine.
Processing and cooking generally does not effect antioxidants. In fact, the amount of antioxidant in many vegetables increases when microwaved, steamed or boiled.
Eat your way to health.
