How does antioxidants work in the body?
They donate electrons to free radicals, which neutralizes them and prevents them from causing harm. Bottom Line: Antioxidants are molecules that fight damage by free radicals, unstable molecules that can harm cellular structures. Antioxidants do this by giving electrons to the free radicals and neutralizing them.
Cells may function poorly or die if this occurs. To prevent free radical damage the body has a defense system of antioxidants. Antioxidants are molecules which can safely interact with free radicals and terminate the chain reaction before vital molecules are damaged.
- Everyone from scientists to spiritual gurus have taken to extolling the health benefits of notable antioxidants such as blueberry, pomegranate, acai berry, and goji berry. Drink manufacturers everywhere are picking up on the antioxidant buzz, and wild new health beverages are flooding the marketplace everyday.
- Antioxidants prevent a chemical process known as “oxidation,” which is a natural part of living and aging. Oxidation damages cells and can lead to the development of disease, including Alzheimer's, heart disease, and cancer. Antioxidants are found in fruits, vegetables, nuts, beans, grain cereals, and other foods.
- Antioxidants and free radicals. Antioxidants are found in certain foods and may prevent some of the damage caused by free radicals by neutralising them. These include the nutrient antioxidants, vitamins A, C and E, and the minerals copper, zinc and selenium.
An antioxidant is a molecule that inhibits the oxidation of other molecules. Oxidation is a chemical reaction that can produce free radicals, leading to chain reactions that may damage cells. Antioxidants such as thiols or ascorbic acid (vitamin C) terminate these chain reactions.
- Antioxidants are substances that may protect cells from the damage caused by unstable molecules known as free radicals. Free radical damage may lead to cancer. Antioxidants interact with and stabilize free radicals and may prevent some of the damage free radicals otherwise might cause.
- The first thing to know is that both oxidants and antioxidants are naturally present in bodies, even without supplements. In fact, oxidants are not necessarily bad. Natural oxidants create so-called “free radicals” in our bodies to help kill bacteria and to get rid of other unwanted invaders.
