The criterion for the antioxidant capacity of foods is expressed in ORAC values. ORAC stands for “Oxygen Radical Absorbance Capacity,” an antioxidant parameter developed at the American National Institutes of Health in Baltimore, USA. The higher the ORAC value, the higher the antioxidant value a food has.
ORAC values are given as (mol TE / 100g) (micromoles of Trolox equivalent per 100 grams). The Trolox equivalent is used as a measure of antioxidant capacity. The USDA (US Department of Agriculture) recommends that an adult consume about 3,000 to 5,000 ORAC units per day.
Most of us have heard that blueberries are very good for our health. Did you know that there are about 60 foods and spices that are obviously even better (by better we mean … have a higher antioxidant value)?
