PORTLAND, Maine, May 5 USDA's database of antioxidantvalues for various foods, places blueberry juice at the top of the list amongmore than a dozen juices tested including pomegranate, apple, prune, cranberryand Concord grape. Using the Oxygen Radical Absorption Capacity (ORAC)testing procedure, the gold standard of antioxidant measures for detecting thefree-radical scavenging ability of foods, blueberry juice had the highest ORACscore of 2,906 umol TE/100g. The ORAC database was prepared by the USDA'sAgricultural Research Service and is available at

"A serving of 100% fruit juice is a healthy way to get one of your dailyfruit servings," said Susan Davis, MS, RD, nutrition advisor to the WildBlueberry Association of North America. "A glass of juice can be arefreshing, nutritious energy boost, but moderation of how much juice youdrink is key. Control calories by making juice part of an overall healthydiet that includes many fruits and vegetables and balances carbohydrates,fats, protein, and fiber."

The USDA Dietary Guidelines for Americans recommends anywhere from 2 1/2to 6 1/2 cups or 5 to 13 servings a day of colorful fruit and vegetablesdepending on age, gender and activity level. According to Davis, a 4-ounceglass of 100% fruit juice equals 1/2 cup of fruit and counts toward dailyfruit serving goals. "Try fresh, frozen, canned, juice or dried, because allforms count when you're trying to add more fruits and vegetables into yourdiet. Make sure you get a colorful variety of fruits and vegetables, and whenit comes to blue, eat at least 1/2 cup of Wild Blueberries or drink 4 ouncesof Wild Blueberry juice every day," said Davis.

The ORAC assay has become the most referenced source of antioxidant valuesfor food. Manufacturers of a wide range of food products highlight ORACvalues of their products on labels and web sites to provide information andguidance to their customers on the sometimes confusing information emerging ondietary antioxidants.

While the recent USDA data collection didn't specifically list ORACresults for Wild Blueberries or Wild Blueberry juice, versus just blueberry,previous USDA tests have shown Wild Blueberries outperform more than 20 otherfruits in the ORAC test. A landmark study previously conducted by the USDAshowed that a one-cup serving of Wild Blueberries had more antioxidantcapacity than a serving of cranberries, strawberries, raspberries, apples andeven cultivated blueberries. (Journal of Agricultural and Food Chemistry,52:4026-4037, 2004.) Wild Blueberries are concentrated sources of protectivenatural compounds that have antioxidant and anti-inflammatory effects.
