How Antioxidant Foods Work Oxidation is a naturally occurring process in the body so there is really no way for us to avoid or prevent it from happening. Even the mere act of breathing causes oxidation to take place. That being said, free radicals, as by-products of oxidation, will always be present in our body. If they are healthy molecules, well that's a different story all together. When free radicals start stealing electrons from healthy cells, that process causes many disorders to occur in the body. The cells will grow weak until they are eventually destroyed. Hence, diseases such as cardiovascular disease, Parkinson's, Alzheimer's, senility, and cancer are often attributed to the contributing factor of free radicals. Free radicals are highly reactive chemical substances which are produced whenever our body undergoes the process of oxidation, e.g. breathing. When free radicals are released, they immediately latch unto other molecules, stealing their electrons and in so doing, turning them into unstable molecules like themselves. Anti Aging Antioxidant Research shows that cells are only allowed so many cell divisions in a human lifetime before they would have to give out. Based on their findings, scientists say that by the time you are 20 years old, most of the cells that make up your body have already used up half of their available cell divisions in their cell lifespan. Antioxidant Support Free radicals are a natural consequence of oxidation - that vital process that allows our body to function normally. Free radicals actually play an important role in a number of biological processes, some of which are necessary for life, such as intracellular killing of bacteria by neutrophil granulocytes.
