As we breathe, we take in oxygen which the cells of our bodies require. The cells then naturally produce unstable molecules as a by-product which we call 'free radicals'. These free radicals, if not stabilized, can cause oxidative damage to our bodies. Oxidative stress also occurs from environmental exposure to tobacco smoke, or the sun causing sunburn. Antioxidants may protect your cells by stabilizing these free radicals, preventing and repairing the damage that they can cause.

If we don't take in enough antioxidants, then health problems can occur such as heart disease, macular degeneration, diabetes and cancer. They have been shown to enhance our immune defenses which may in turn lower the risk of cancer and infection. Recent studies have shown that 5 servings of antioxidant rich fresh fruit and vegetables may reduce the risk of stroke by up to 25 percent.

Antioxidants are abundantly found in brightly coloured fruits and vegetables, as well as in nuts, grains, and some meats, poultry and fish.
