Oxidation is a normal process that occurs during normal cell function. But a small portion of cells become damaged during oxidation and become free radicals, which trigger a chain reaction that damages cells and cell DNA. Cells with damaged DNA grow and reproduce abnormally. This production of free radicals is called oxidative stress, which has been linked to the development of a range of diseases, including certain forms of cancer, heart disease, Alzheimer’s, Parkinson’s, cataracts, and macular degeneration. Free radicals may also contribute to the aging process. Free radicals are formed when you exercise, when your body converts food into energy, and from a variety of environmental sources, including cigarette smoke, air pollution, alcohol, and sunlight.
