A study from Tufts University in Boston ranks the antioxidant value of commonly eaten fruits and vegetables using an analysis called ORAC (Oxygen Radical Absorbance Capacity). This is a test tube analysis that measures the total antioxidant power of foods and other chemical substances

Some antioxidants that we know of are Vitamin C, E, and beta carotene to name a few. Some people forget that some vitamin antioxidant supplements are very popular but the most important part of the nutrients is in the foods we eat.
