Antioxidants
When you leave an apple exposed to the air, it turns brown. The damage to the apple is caused by oxygen in the air, and is called oxidation. A substance that can reduce oxidation is called an antioxidant. Antioxidants are said to help your body repair cells and may even reduce the effect of aging.
Common antioxidants are nutrients like B vitamins including Beta Carotene, Vitamins C and E and selenium. Foods like grape seed extract and pomegranate juice are high in antioxidants. Antioxidants may be taken as supplements or ingested as food. Most experts believe that getting antioxidants from food is the most healthful way to obtain them.
