The exposed flesh of the apple soon turns brown. That's oxidation at work. Oxidation Oxidation provides needed energy for life, yet within our bodies the process is a two-edged sword. Unfortunately, a small number of the oxygen molecules we breathe are converted within our bodies to unstable free radicals. Free radical-caused oxidation produces premature aging and sets us up for serious illness, including cancer and heart disease.
Oxidation is literally decay.
Oxidation in our environment is seen as rusting of metal, rotting of meat, browning of apples, and the brittle changes in old rubber. Because of overexposure to free radicals, our bodies need outside help. Because our diets are inadequate, we need to take antioxidant supplements. Premature decay leads to premature aging, degenerative disease, and life-threatening illness. Nutrition Many other medical experts are making equally strong statements about the relationship between nutrition and disease.
