What is antioxidant antiaging therapy? Modern theories of aging are generally looked at in two theoretical ways - the damaged theories and the programmed theories. The damage theories of antiaging primarily look at the damage that our cells incur over time. Hence, this aspect of antioxidant antiaging therapy focuses more on extrinsic aging, which is the aging process compounded by externally caused factors. Catechins are the natural antioxidants found in the Camellia sinensis plant where we get our green tea, oolong tea, and black tea. In the carotenoid group, beta-carotene is the most common natural antioxidant. Another name for beta-carotene is vitamin A, that essential vitamin that helps prevent eye damage. Antioxidant foods are powerful substances that can neutralize free radicals before they damage your body's cells. This is the major reason why scientists are continuing to conduct studies on antioxidant foods and the benefits that the body can incur from them. Antioxidant Foods: Which Foods? As mentioned earlier, many foods with high antioxidant levels are vegetables and fruits. We've been eating them for centuries and it's only now that scientists are beginning to discover exactly what makes them healthy for the body. Antioxidants. What exactly are they? The term is familiar to us. We hear them mentioned all the time whenever there's a new scientific study being released in the American Health Journal or some such explaining how antioxidant juice from berries can aid in liver function or how antioxidant juice from red wine is the scientific reason behind the French paradox. Scientists have also pointed to free radicals as the cause of some of the symptoms of aging, such as atherosclerosis, alcohol-induced liver damage, alpha 1-antitrypsin in the lung, and even emphysema. Now, don't get this wrong. Free radicals are still necessary for life, but in order to prevent yourself from developing these diseases, you need to take action in keeping free radicals at a minimum. Prior, a USDA nutritionist and research chemist based in Little Rock, Ark explains that berry antioxidants were ranked according to their total antioxidant capacity. However, they were surprised to find that besides berry fruits, antioxidants may also come from the most unexpected foods as well. Prior and his colleagues used the most advanced technologies available to tabulate antioxidant levels in more than 100 different types of berry fruits, vegetables, nuts, and spices.
