The USDA Human Nutrition Research Center on Aging (www.hnrc.tufts.edu) at Tufts University in Boston has found that blueberries rank #1 in antioxidant activity when compared to 40 common fresh fruits and vegetables. Concord grape juice is next on the list with about two thirds of the antioxidant activity of blueberries followed by strawberries. So pass the blueberries, please!
