What is ORAC ?!

ORAC is short for Oxygen Radical Absorbance Capacity. It is a test tube analysis that measures the total antioxidant power of foods and other chemical substances. Antioxidants are essential to good health, especially with respect to aging and age related disorders, since they increase our resistance to disease and boost immunity.
ORAC measures how well the antioxidants in food neutralize free radicals. The higher the ORAC score, the greater is the food's antioxidant capacity. The USDA (United Stated Department of Agriculture) recommends an ORAC unit ingestion of about 3000 to 5000 units daily by eating 5-9 different kinds of vegetables and fruits.
