In the study about antioxidant juice from pomegranates, researchers have found that the substance can effectively reverse the progression of atherosclerosis, or the hardening of the arteries. Atherosclerosis causes decreased blood flow that can lead to heart attacks or strokes. The tests showed that antioxidant juice from pomegranates reduced the effects of stress on human blood vessel cells by stimulating the production of nitric oxide. Antioxidant Ever wondered how you get all those wrinkles? Those annoying crow's feet at the corners of your eyes? Or those laugh lines around your mouth? Sure, these things are but part of the normal aging process. But what causes aging anyway? And is there anyway to retard it? In biological systems, the normal processes of oxidation are what lead to aging. Oxidative stress is a process which many a scientist has linked with the development of chronic and degenerative diseases such as heart disease and cancer. Antioxidant fruits may be plain fruits, cereals, and vegetables. Some antioxidant fruits may also be taken in dried, powdered forms, like dietary supplements or pills. Red wine has always been considered more beneficial compared to white wine in preventing heart disease. Apparently, the antioxidant red grapes are the reason for that since red wine is fermented with the seeds while white wine is not. This most recent discovery of significant antioxidant red grapes adds to the growing reputation of the red grape as a healthful food. The first ever antioxidants to catch the attention of scientists and the vitamin supplement industry is beta-carotene or more commonly known as Vitamin A. Now, you can find antioxidant supplements in the form of Vitamin A capsules in almost any pharmacy or health food store. Beta-carotene antioxidant supplements generally come from orange, yellow, and green leafy vegetables and fruit. 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.
