The best way to lay an antioxidant-rich foundation that's inhospitable to toxins and free radicals is through a combination of whole foods. With antioxidant supplements still far from the high expectations of the scientific community, you can in the meantime turn to the more reliable source of these helpful compounds, which are antioxidant foods. According to their findings, the overall best sources of antioxidant fruits under the berry category are dog rose, sour cherry, blackberry, strawberry, raspberry, crowberry, blueberry, and black currant. Under the antioxidant fruits category are pomegranates, grape, orange, plum, pineapple, lemon, dates, kiwi, Clementine, and grapefruit. The aging process brings with it not only wrinkly skin or tired joints and muscles. Those can be tolerated. After all, they are part of the natural cycle of life. But what isn't natural is disease. They are disorders - unnatural conditions of the body. Aging is caused by harmful molecules called "free radicals. It has been observed that people who eat a lot of foods rich in beta-carotene are not generally prone to cancer. However, the beta-carotene antioxidant supplements didn't last that long in the industry. It seemed that in most major trials designed to see whether taking extra beta-carotene antioxidant supplements could ward off cancer, beta-carotene didn't do a good job at it. Many forms of cancer are thought to be the result of reactions between free radicals and DNA, resulting in mutations that can adversely affect the cell cycle and potentially lead to malignancy. 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. The data on antioxidant vitamins is incomplete for the most part but up to 30 percent of Americans are already taking some form of antioxidant vitamin supplement along with their diet. Due to the lack of sufficient data to support the success of antioxidant vitamins supplement against cardiovascular diseases and other such degenerative illnesses, the American Heart Association does not recommend using antioxidant vitamins supplements.
