Wild blueberries surpass cultivated blueberries in number of antioxidants by 50%, according to the US Department of Agriculture (USDA). Wild blueberries score over 13,000 for total antioxidants, whereas cultivated blueberries rank second with only 9,000. Antioxidants are measured in foods by their oxygen radical absorbance capacity (ORAC), a measurement standard developed by the USDA. Telling the difference between a wild and cultivated blueberry is based on their size: Cultivated blueberries are generally larger and juicier, while wild blueberries are typically half the size.
