Antioxidants act as cell protectors. Oxygen, an essential element for life, can create
damaging by-products during normal cell functioning. Antioxidants counter act these
cellular by-products, called free radicals, and bind with them before they can cause
damage. If left unchecked, free radicals may cause heart damage, cancer, cataracts,
and a weakened immune system.
Antioxidants work by binding to the free radicals; transforming them into non-damaging
compounds, or repairing cellular damage. Antioxidants come in a variety of forms and
include Vitamin C, Vitamin E, the carotenoids, and selenium.
Good sources of antioxidants include fruits and vegetables. The highest concentrations
are found in the most deeply or brightly colored vegetables and fruits (spinach, carrots, red bell
peppers, tomatoes).
