Unfortunately, human beings are one of the few animal species that do not produce their own antioxidants. That is why we depend so much on our diet for our source of antioxidants. 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. Debasis Bagchi, announced that Activin seemed to exhibit more powerful potential compared to the other antioxidants. "Our studies show that Activin is a more potent antioxidant than vitamins C, E, and beta-carotene - up to seven times more potent," Bagchi said when he reported the findings of their study at the Experimental Biology conference in New Orleans. Enzymes superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase, these are only a few of the substances found in the body that can help repair cell damage. But that's only as far as repair is concerned. What about controlling free radicals in the form of prevention? Now, this is where antioxidant support comes in. By neutralizing, they themselves become oxidized. For this reason, our bodies are always in need of a constant source of antioxidants. How antioxidants work is a two-way process. First is the chain-breaking. This is where the antioxidant comes in to break the chain reaction of free radicals turning other molecules into free radicals like them. Perhaps due to this alarming number, much of scientific researches conducted in the US today have recently been focused on how antioxidant vitamins may reduce the risk of cardiovascular disease. 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 reason free radicals are highly unstable is that they have an unpaired electron which they try to recompense by stealing an electron from a stable molecule. This actually sets off a chain reaction that can damage the body's proteins and cell membranes, weaken the cell's natural defenses, and disrupt the cell's DNA.
