Antioxidants may also enhance immune defense and therefore lower the risk of cancer and infection. Antioxidant supplements serve as the protective coating; when they are introduced in the body, they gather up the free radicals, preventing them from damaging the cells. Antioxidant supplements are a great help to the body in keeping the free radicals under control so they do not cause considerable damage to the cells. Antioxidants are plentiful in more common vitamins such as retinol or Vitamin A, ascorbic acid or Vitamin C, tocopherol or Vitamin E, and selenium. They can be nutrients (vitamins and minerals) as well as enzymes (proteins in your body that assist in chemical reactions).
Antioxidants are thought to thwart heart disease by preventing oxidation. Antioxidants combat chronic inflammation. Antioxidants include some vitamins (such as vitamins C and E), some minerals (such as selenium), and flavonoids, which are found in plants. The best sources of antioxidants are fruits and vegetables. Antioxidants are compounds that protect cells against the damaging effects of reactive oxygen species, such as singlet oxygen, superoxide, peroxyl radicals, hydroxyl radicals and peroxynitrite. An imbalance between antioxidants and reactive oxygen species results in oxidative stress, leading to cellular damage.
Antioxidants help neutralize free radicals which are unstable molecules linked to the development of a number of diseases including cancer, cardiovascular disease and other age-related conditions such as Alzheimer's. According to the USDA database of the antioxidant activity of selected foods (ORAC values), blueberries rank among the highest on a per serving basis. Antioxidants, however, stop the chain-reaction by giving up electrons and neutralizing free radicals so that they cannot induce any more oxidative damage. Unlike other molecules, antioxidants do not become reactive when they lose an electron. Antioxidants are nutrients (vitamins and minerals) as well as enzymes (proteins in your body that assist in chemical reactions). They are believed to play a role in preventing the development of such chronic diseases as cancer, heart disease, stroke, Alzheimer's disease, Rheumatoid arthritis, and cataracts.
Antioxidants neutralize free radicals, but merely taking some vitamin C and E won't cut it. You need as much antioxidant support as possible from a wide variety of sources. Antioxidants counteract these free oxidants and stop their harmful reaction. Antioxidants are believed to be effective in helping to prevent cancer, heart disease, stroke and a variety of other ailments associated with natural aging. Specifically antioxidants prevent ailments by destroying free harmful radicals inside the human body.
Antioxidants neutralize the damage to cells caused by free radicals and may be relevant to AMD if oxidative damage to the retina leads to AMD. Antioxidants in foods are generally considered safe, and studies of antioxidant supplements generally have not reported adverse effects. However, the research does point to some potential concerns; for example, beta-carotene supplements may increase the risk of lung cancer in smokers, and vitamin E supplements may increase the risk of bleeding in certain individuals. Antioxidants in plant cells mainly include glutathione, ascorbate, tocopherol, proline, betaine and others, which are also information-rich redox buffers and important redox signaling components that interact with cellular compartments. As an unfortunate consequence of aerobic life for higher plants, reactive oxygen species (ROS) are formed by partial reduction of molecular oxygen.
Antioxidant foods like MegaHydrate help defy the aging process. It is safe, having been tested and shown to have no known side effects. Antioxidant supplements need to be considered medicinal products and should undergo sufficient evaluation before marketing. Antioxidant compounds cannot just be lumped together, as they each have distinct effects. Starting antioxidant supplements earlier in life may be required for heart protection.
Antioxidants protect the body’s cells against oxidants. These can damage the cell’s surface, alter its DNA or completely kill the cell. Antioxidants can thus play a protective role in keeping the fatty acids in the brain healthy. After all, about 60 percent of the brain is made of fat. Antioxidant compounds in leafy materials are generally located in conduit structures called the apoplast and symplast [47 -49 ]. Maceration alone is not sufficient to extract these compounds from the structures.
