To achieve maximum stability, free radicals therefore steal electrons from other molecules around them and in so doing, destroy the cell membranes and weaken the cell. Free radicals cause a chain reaction of "electron stealing" because the minute they start taking away electrons from other molecules, those molecules become free radicals themselves. And so, studies began to look towards other sources of antioxidants as possible antioxidant supplements. Vitamins C and E were the next contenders but again, studies showed mixed results. Although Vitamin C antioxidant supplements didn't look as though it could reduce the risk of cancer or heart disease, it didn't have any adverse effects either. Antioxidant Berry Someone once said that anything rich, creamy, and delicious couldn't be good for you. It would have been better if you only end up with thunder thighs after a bowl of rich cream, but there are far more serious health risks you'll have to consider when you indulge yourself with such things. 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. With the possible exception of longevity medicine, antioxidant antiaging is one of the fastest growing segments of medicine. How antioxidant antiaging works As you process food for energy, your body produces substances that are highly unstable. The process is called oxidation and the substance produced is called "free radicals. Antioxidant Red Grapes A New Orleans study has revealed a new antioxidant that is believed to be more potent that vitamin C, E, and beta-carotene. This new disease-fighting substance is said to be found in red grapes, whose juice and skin may offer more than just wine. The antioxidant red grapes are contained in the seeds of the fruit.
