Editor's Note: USDA scientists analyzed antioxidant levels in more than 100 different foods, including fruits and vegetables. Each food was measured for antioxidant concentration as well as antioxidant capacity per serving size. Cranberries, blueberries, and blackberries ranked highest among the fruits studied. Beans, artichokes, and Russet potatoes were tops among the vegetables. Pecans, walnuts, and hazelnuts ranked highest in the nut category.

USDA chemist Ronald L. Prior says the total antioxidant capacity of the foods does not necessarily reflect their health benefit. Benefits depend on how the food's antioxidants are absorbed and utilized in the body. Still, this chart should help consumers trying to add more antioxidants to their daily diet.
