ANTI-OXIDANTS vs FREE RADICALS


Antioxidant vitamins C, E and a family of plant chemicals known as carotenes (beta carotene is one of more than 600 carotenes found in foods) may protect your muscles from damage caused by free radicals. Free radicals are metabolic byproducts of vigorous exercise which can damage body tissues. Antioxidants neutralize these free radicals, rendering them harmless.

Where to get antioxidants? Citrus fruits, strawberries, tomatoes and peppers are all brimming with vitamin C. Vitamin E is found in whole grain breads and cereals, nuts, wheat germ and vegetable oils. Beta carotene, and its other carotene cousins, hide out in dark green and orange-colored fruits and vegetables, such as carrots, cantaloupe and broccoli. The darker the color, the more carotenes.

One word of caution however. In the amounts contained in food, these substances act as antioxidants. In massive doses, they may be pro-oxidants (harmful to tissues). Some research studies have actually discontinued the use of high dose beta carotene supplements because of their potentially harmful effects on body tissues. In summary, the effectiveness of antioxidant supplements is uncertain, but the evidence of anti-oxidants fighting free radicals is yet another reason for consumption of the aforementioned wonderful foods.
