Fighting Disease By Eating Antioxidants In Food

Free radicals are those by-products given off by the daily metabolism process of the body. In addition, free radicals enter the body through the body’s respiratory system. These free radicals are found in polluted air, cigarette smoke, etc. Free radicals in the blood stream have been linked to causing heart disease, high blood pressure and cancer.

Antioxidants are an integral component in fighting free radicals. The function of antioxidants is to negate the destructiveness of free radicals within the blood stream. The only source of antioxidants is in the food we eat and the taking of supplements.
