WASHINGTON — The U.S. Department of Agriculture’s Agricultural Research Service has compiled a database of the antioxidant capacities of 277 selected foods, providing access to antioxidant values for a variety of foods.
Scientists may use the database to facilitate research into how antioxidants correlate to health benefits. This work continues on a 2004 A.R.S. release of the estimates of the antioxidant capacities in 171 foods.
A.R.S. researches at the Nutrient Data Laboratory in Beltsville, Md. prepared the database while working with colleagues at the A.R.S. Arkansas Children’s Nutrition Center in Little Rock. A portion of the foods listed were analyzed for their Oxygen Radical Absorbance Capacity (ORAC) at the Arkansas center because ORAC is a method of evaluating the antioxidant capacities in foods.
The database may be found at ars.usda.gov/nutrientdata/ORAC.
