    Best Antioxidant Foods

    All living creatures need oxygen to survive. However, the air that we inhale to stay alive can trigger health problems by producing reactive oxygen species or free radicals in the body. Oxygen is an extremely reactive element. It can easily combine with other substances, causing oxidation reactions. Free radicals, produced during oxidation, are unstable molecules, which trigger a series of reactions in the body. Free radicals are associated with cardiovascular diseases, cancers, premature aging and numerous ailments. By inhibiting oxidation of molecules, antioxidants prevent formation of free radicals in the body. Antioxidants usually act as reducing agents. By oxidizing themselves, antioxidants terminate the chain reactions triggered by oxidation.
