Scientists at the Jean Mayer USDA Human Nutrition Research Center on Aging at Tufts University ranked blueberries number one in antioxidant activity compared with 40 other commercially available fruits and vegetables.* That means a serving of blueberries has more of the antioxidant power you need to fight aging, cancer and heart disease .Scientists attribute the health benefits of blueberries to antihistamines and other natural compounds (phytochemicals) found in blueberries. Fresh, frozen or dried, blueberries are number one in antioxidant activity when measured against comparable forms of other commercially available fruits and vegetables.
