ORAC(Oxygen Radical Absorption Capacity) is the favored choice in the science community in measuring the antioxidant capacity of foods. Blueberries, blackberries, apple, eggplant and other foods have different orac values. ORAC measures how well the antioxidants in food neutralize free radicals.
The Agriculture Research Service of the United States Department of Agriculture has recently provided data on the ORAC values of 277 food items. The data is available for download at http://www.ars.usda.gov/Services/docs.htm?docid=15866.
