There is some research though that antioxidant fruits may be taken better if you actually include them in your diet. Fruit, vegetables, and cereals in your diet have additional benefits compared to taking antioxidant fruits supplements. Scientists point out that this might be because consuming antioxidant fruits in food may provide a combination of lesser-known but potent antioxidant substances, which may afford greater effect than that of any single nutrient or individual antioxidant supplement. Free radicals at a minimum can be good for the body since their function is to steal electrons from atoms of other molecules, but only if the molecule they're stealing the electrons from are foreign molecules in the first place. If they are healthy molecules, well that's a different story all together. Hence, this aspect of antioxidant antiaging therapy focuses more on extrinsic aging, which is the aging process compounded by externally caused factors. On the other hand, the programmed theories are primarily concerned with the genetics of how long and how efficient our cells can maintain optimum health. If there is one other thing you need to know about herbal antioxidants, it is that they are not naturally found in the body. Human beings are one of the few organisms that cannot produce their own herbal antioxidants for the body's use. That is why we have to depend on our diet in order to get our dose of herbal antioxidants. Previous studies have shown that antioxidant vitamins, such as vitamin E, vitamin C, and beta carotene (a from of vitamin A), have potential health-promoting properties. 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. 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.
