This is often done to replace nutrients that may have been lost through handling. Applies to grains in which the outerlayer, where the B vitamins and minerals are concentrated, is not removed during processing. In order to understand the importance of antioxidants, it is first necessary to understand oxidation. Inside the body, oxidation can severely damage cells and allow diseases to get a foothold. Destructive oxygen byproducts, called free radicals, are produced both in our bodies and in the environment by factors like cigarette smoke and polluted air.
Antioxidants seem to deactivate free radicals, and therefore protect cells from damage.
Some research shows that these vitamins may reduce the risk of heart disease and cancer. In addition, antioxidant vitamins, especially vitamins C and E, appear to play an important role in protecting the body against cancer. They seem to block the formation of chemical carcinogens in the stomach, protect DNA and fats in the blood from damage, and enhance the function of the immune system. Based of these findings, experts recommend eating a balanced diet that includes at least five to six servings of fruits and vegetables high in antioxidants each and every day. Antioxidant nutrients can be obtained by taking supplements too, but doctors agree that vitamin pills are no substitute for a healthy diet.
