A AN NT TIIO OX XIID DA AN NT TS S& &O OR RA AC CV VA AL LU UE ES S As oxygen interacts with cells, it may change certain cells, creating free radicals. Free radicals cause harmful effects in cells, possibly leading to aging and diseases such as cancer, heart disease, and Alzheimer’s. Antioxidants can prevent or reduce damage by “neutralizing” the damaging effects of free radicals. ORAC (Oxygen Radical Absorbance Capacity) measures the antioxidant activity of various foods. The higher the ORAC value, the greater the antioxidant activity. The USDA suggests eating a variety of multiple servings of fruits and vegetables daily and nuts too with a goal of 3,000 ORAC Units per day.
