ORAC WHAT IS ORAC? You may have seen the term “ORAC” on food and nutritional supplement labels and wondered what does this acronym mean? Let’s take a closer look. In a nutshell, ORAC refers to Oxygen Radical Absorbance Capacity, a laboratory analysis that provides an overall measure of a food's or a supplement’s antioxidant activity. ORAC was developed in 1992 by Dr Guohua Cao, a researcher at the National Institute on Aging in the U.S. The ORAC test basically consists of challenging a food with an oxidizing agent and then measuring the overall capacity of that food to resist oxidation. https://www.nationalnutrition.ca/antioxidants/orac.html #orac
