Found this great article on Huffington post today written by David Perlmutter, M.D.
Turn on the television, open a magazine or listen to the radio and in short order you will no doubt be exposed to an advertisement extolling the virtues of some newly discovered exotic fruit juice that has the highest antioxidant content on the face of the earth. You may wonder — why all the hype? What is the benefit of an antioxidant?
Antioxidants are chemicals that break down or neutralize the damaging effects of free radicals — chemicals produced as a byproduct of normal cellular metabolism. Under normal circumstances, there is a balance between the rate at which free radicals are produced and the rate at which they are eliminated by the action of antioxidants.
