Antioxidants - Why You Need 'Em
What Are Antioxidants?
Antioxidants fight the oxidation process, a chemical reaction that can cause damage to many cells in your body. While there are many ways to describe what antioxidants do inside the body, one definition of antioxidants is any substance that inhibits oxidation, especially one used to counteract the deterioration of stored food products or removes potentially damaging oxidizing agents in a living organism.
Antioxidants include dozens of food-based substances you may have heard of before, such as carotenoids like beta-carotene, lycopene and vitamin C. These are several examples of antioxidants that inhibit oxidation, or reactions promoted by oxygen, peroxides and/or free radicals
Benefits of Antioxidants
Antioxidants come up frequently in discussions about good health and preventing diseases. These powerful substances, which mostly come from the fresh fruits and vegetables we eat, prohibit (and in some cases even prevent), the oxidation of other molecules in the body. The benefits of antioxidants are very important to good health, because if free radicals are left unchallenged, they can cause a wide range of illnesses and chronic diseases. Research suggests that when it comes to longevity and overall health, some of the benefits of consuming antioxidant foods, herbs, teas and supplements include:
- Slower signs of aging, including of the skin, eyes, tissue, joints, heart and brain
- Healthier, more youthful, glowing skin
- Reduced cancer risk
- Detoxification support
- Longer life span
- Protection against heart disease and stroke
- Less risk for cognitive problems, such as dementia
- Reduced risk for vision loss or disorders like macular degeneration and cataracts
- Antioxidants are also added to food or household products to prevent oxidation and spoilage
Antioxidants Fight Against Damaging Free Radicals
The human body naturally produces free radicals and the antioxidants to counteract their damaging effects. However, in most cases, free radicals far outnumber the naturally occurring antioxidants. In order to maintain the balance, a continual supply of external sources of antioxidants is necessary in order to obtain the maximum benefits of antioxidants. Antioxidants benefit the body by neutralizing and removing the free radicals from the bloodstream.
How The Body Defends Against Oxidative Stress
Oxidative stress occurs when the production of free radicals goes beyond the protective defenses in the body. Oxidative stress and free radical damage to cells may initiate the early stages of cancer and heart disease. Free radicals are also suspect in the development of Alzheimer's disease, arthritis, cataracts, diabetes, kidney disease, and age-related blindness.
