There have been countless articles written over the past decade about life extension, free radicals and antioxidants.
The theory is that antioxidants neutralize free radicals. Whether we like it or not, free radicals are a normal part of life and they do contribute to aging and illness.
The good news is that our bodies’ natural defense system normally neutralize free radicals, rendering them harmless.
However, this ability can be overpowered by environmental factors such as pollutants, UV radiation and even alcohol . And there is good evidence that free radicals do contribute to aging and can lead to a number of illnesses such as cancer and heart disease.
Free radicals and antioxidants
Antioxidant proponents believe that free radicals can be neutralized by antioxidants which, in turn, contributes to life extension by helping prevent chronic diseases.
Examples of antioxidants include:
How to incorporate antioxidants into your diet
The best and easiest way to incorporate antioxidants into your diet is by eating a variety of fresh fruit and vegetables. Citrus fruits, green peppers, broccoli, green leafy vegetables, strawberries, raw cabbage and potatoes are all good sources of Vitamin A. Wheat germ, nuts, seeds, whole grains, green leafy vegetables, vegetable oil and fish-liver oil are rich in Vitamin B. For beta-carotene, there are carrots, squash, broccoli, sweet potatoes, tomatoes, kale, collards, cantaloupe, peaches and apricots.
If you can't or choose not to eat these fruits and vegetables regularly, there are supplements available you can use to make up for any deficiencies.
Life extension or not life extension?
Despite what you might read elsewhere, there is no scientific proof that taking antioxidants in pill form will neutralize free radicals and, thus, lead to life extension.
If you believe that you should be increasing the amount of antioxidants in your diet, be sure to talk to your doctor before you start taking any supplements.
And remember. There's nothing bad about adding a few servings of antioxidant-rich fruits and vegetables to your diet.
While this may not lead to real life extension, it should lead to healthier life.
