How to Survive Free Radical Damage
Copyright 2006 Marc David
Let's face it ...
You've probably heard about free radicals before and you might
have just assumed it was a bunch of B.S. But have you ever
wondered exactly what are free radials, what can cause them and
how you can combat the effects?
If you've heard about them but were curious as the natural of
them, you'll be interested in this article.
What Are Free Radicals?:
An atom or group of atoms that has at least one unpaired
electron and is therefore unstable and highly reactive. In
animal tissues, free radicals can damage cells and are believed
to accelerate the progression of cancer, cardiovascular disease,
and age-related diseases.
What Can Cause Them?:
External Factors -
* Smoking * Food (ingested substances, preparation, pesticides)
* Pollutants in the air (chemicals in the area) * Radiation *
Excessive amounts of sunlight * Alcohol * Drugs
Internal Factors -
* Immune system * Stress * Energy production (exercise) * Many
other chemical reactions in the body * Body's own out of control
production (just as damaging as external factors)
What Diseases Are Linked To Them?:
* Cancer * Arteriosclerosis, atherosclerosis. * Heart disease. *
Cerebrovascular disease. * Stroke. * Emphysema (Cross et al
1987). * Diabetes mellitus (Sato et al 1979). * Rheumatoid
arthritis (Cross et al 1987, Greenwald & Moy 1979, 1980,
Halliwell 1981, 1989, Del Maestro et al 1982, Fligiel et al
1984). * Osteoporosis (Hooper 1989, Stringer et al 1989). *
Ulcers. * Sunburn. * Cataracts (Niwa & Hansen, 1989, Yagi 1977).
* Crohn's disease (Niwa & Hansen 1989). * Behcet's disease *
Aging * Senility
Benefits of Free Radicals:
* Essential role in the human body's defense * Virus and
bacteria are showered with a type of toxic shower when the body
intentionally produces free radicals as part of its immune
defense systems to destroy invaders
Antioxidant "Free Radical" Prevention Methods:
* Natural enzymes * Nutrients (vitamins A, C, E primary
antioxidants) * Self-Repair
What You Can Do To Prevent Free Radical Damage:
* Vitamin and mineral supplementation * Steer clear of heavy
processed foods * Diet high in fruits and vegetables
Antioxidant Foods:
* Artichokes * Bilberries * Black beans * Blackberries * Black
plums * Blueberries * Cauliflower * Cranberries * Gala apples *
Granny Smith apples * Pecans * Peppers * Pinto beans * Plums *
Prunes * Raspberries * Red beans * Red Delicious apples * Red
kidney beans * Russet potatoes * Strawberries * Sweet cherries *
Tomatoes * Wild blueberries
Summary:
It seems like free radicals are discussed a lot when it comes to
exercising only because the more you exercise, the more free
radicals you will have because of energy production. That's not
entirely a bad thing. The name "free radical" sounds very
negative but it's there for a purpose as well, primary as a
defense system. Of course, it can go out of control as well.
Monitoring the levels of free radicals is difficult to measure.
Vitamins A, C and E are the primary nutrients to prevent free
radical damage.
Most will recommend a diet high in fruits and vegetables to
obtain natural antioxidant sources but vitamin supplementation
is also recommended. There's enough evidence to suggest that
food processing today has taken out some of the nutritional
values. True or not, if you eat correctly AND supplement
responsibly, you should be covered per the recommendations.
Marathon runners or high altitude running may require more
Vitamin E 10-14 days before a run because of the extra long term
stress and energy production.
If you stick to a good basic diet with fruits and vegetables and
take a good vitamin supplement, you should be well protected
against excess free radical damage without interfering with the
body's own ability to defend itself.
