What does ORAC mean?

An acronym for oxygen radical absorption capacity, ORAC is a way to measure the antioxidant capacity of a food. Foods with high ORAC values are desirable for their ability to inhibit free radical activity. The ORAC measurement was developed by a scientist at the National Institute of Aging in 1992 and has proven to be a valuable tool in quantifying health benefits associated with consuming fruits, vegetables, and other antioxidant-containing foods and supplements.
