Normal metabolic processes produce reactive byproducts which can do damage if not kept under control. Among these reactive byproducts are three forms of oxygen: molecular oxygen, peroxide and superoxide . They all react by taking electrons from other molecules, a type of reaction called oxidation.

The body prevents damaging oxidations by providing compounds with which the oxidants can react harmlessly. These compounds are called antioxidants. Through the antioxidants found in foods such as pomegranates and green tea, oxidation of your cells is reduced.

Your body's natural functions require healthy cells. When they are damaged, degenerative processes can take hold, resulting in the signs of aging.
