Wordology, Antioxidant

Few people are aware what exactly an antioxidant is. An antioxidant is a substance that inhibits oxidation. It is a substance that removes potentially damaging oxidizing agents in a living organism.

The level of antioxidants in any substance or food is evaluated with an ORAC score, (Oxygen Radical Absorption Capacity). ORAC tests the power of a plant to absorb and eliminate free radicals. These measurements were developed by the National Institute of Aging and are based on 100 grams of each food or herb. Cinnamon, clove, oregano, dark chocolate, and pecans have extremely high ORAC scores.

Antioxidants can be man-made or natural substances.  They are found in many foods. They are also available as dietary supplements. Examples of antioxidants include: Beta-carotene, Lutein, Lycopene, Selenium, Vitamin A, Vitamin C, and Vitamin E. Vegetables, fruits, and nuts are rich sources of antioxidants.

The benefit list of antioxidants is long and includes:
    Slower signs of aging, including 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, such as macular degeneration and cataracts.


Bottom line, antioxidants are generally very good for you, but high-dose supplements of antioxidants may be linked to health risks in some cases, such as high doses of beta-carotene may increase the risk of lung cancer in smokers. High doses of vitamin E may increase risks of prostate cancer and one type of stroke. As my mother used to say, "It can be too much of a good thing."
