What Are They?
An antioxidant is a class of molecules that inhibit oxidization of other molecules. Environmental toxins such as car exhaust or cigarette smoke contain free radicals, which damage cells in your body through oxidation. Antioxidants block this damage by neutralizing the free radical. Vitamins C and E, beta-carotene, lycopene, letein, zeaxanthin, selenium, alpha-lipoic acid, quercetin, ellagic acid, and hesperidin are all examples from this broad category of nutrients.
Antioxidants are found within fruits and vegetables, especially those that are rich in color. For example, blueberries, tomatoes, spinach, carrots, oranges, pomegranates, kiwi, pink grapefruit, and green tea are potent sources, as are coffee and red wine.
Pine bark extract and grape seed extract also contain antioxidants, so does the spice turmeric. Oh, and indulge in a piece of dark chocolate once in a while—it, too, has a high antioxidant content.
Antioxidants are chemical properties, not an actual substance, and act differently depending on the antioxidant type. Each has its own chemical and biological composition therefore it’s best to eat a variety a fruits and vegetables as each antioxidant has a different role in repairing cell damage.
Antioxidants are found in vitamins, therefore a blend of basic antioxidant vitamins and minerals such as C, E, selenium, and beta-carotene are a good place to start. Coenzyme Q10 (CoQ10) can be found in supplement form. N-acetyl cysteine is available only in supplement form, but functions as both an antioxidant and a detoxifying agent.
Cell damage occurs on a daily basis and is linked to disease and symptoms identified with aging. Antioxidants prevent and slow down development of diseases and ailments such as cancer, lung and heart disease, macular degeneration, high cholesterol, blot clot formation, and cataracts.
