Health-conscious consumers looking to power up on antioxidants should look for blueberry juice. The Wild Blueberry Association of North America says the USDA’s database for antioxidant values in various foods names blueberry juice among the best sources for antioxidants. The juice is compared with others such as pomegranate, apple, prune, cranberry and Concord grape.

Using the Oxygen Radical Absorption Capacity (ORAC) testing procedure, the gold standard of antioxidant measures for detecting the free-radical scavenging ability of foods, blueberry juice had the highest ORAC score of 2,906 umol TE/100g.

The USDA Dietary Guidelines for Americans recommends anywhere from 2 1/2 to 6 1/2 cups or 5 to 13 servings a day of colorful fruit and vegetables depending on age, gender and activity level. According to Davis, a 4-ounce glass of 100% fruit juice equals 1/2 cup of fruit and counts toward daily fruit serving goals. “Try fresh, frozen, canned, juice or dried, because all forms count when you’re trying to add more fruits and vegetables into your diet. Make sure you get a colorful variety of fruits and vegetables, and when it comes to blue, eat at least 1/2 cup of Wild Blueberries or drink 4 ounces of Wild Blueberry juice every day,” said Davis.

The Wild Blueberry Association adds, that though wild blueberries weren’t taken into account, past studies show that wild blueberries contain more antioxidants that 20 other antioxidant-rich fruits. The ORAC database has become the most referenced source of antioxidant values for food.
