All About Antioxidant Vitamins
Monday, January 30th, 2012The antioxidant vitamins found in fruits, vegetables, teas and supplements are proving to be powerful agents in the fight against disease causing free radicals.
The original concept involves taking the recommended daily allowance (RDA) of vitamins to a level that would prevent acute deficiency diseases like the Sailor’s disease scurvy. In fact, the RDA’s were created by these very standards.
In recent years, however, research has shown that Vitamins taken in higher doses can prevent sever chronic diseases like cancer and heart disease. A debate still rages, but there is a plethora of research being done on Vitamin A, C, E, the antioxidant vitamins.
A National Institute of Health clinical trial involving people at high risk of developing advanced stages of Age-related Macular Degeneration (AMD), showed that patients’ risk decreased by 25 percent when treated with high doses of antioxidant vitamins and zinc.
In another study at the Center for Disease Control and Prevention (CDC) in Atlanta, it was shown that taking Vitamin E along with multivitamins reduced risk from stroke and heart illness. The mortality risk decreased by 15 percent for these two diseases among the patients who took the combination.
A study investigating the relationship between Vitamin C and cancer has been concluded by the National Institutes of Health (NIH) and it suggests that Vitamin C may fight cancer. What they found in a laboratory setting is that high doses of Vitamin C injected directly into the bloodstream killed cancer cells.
There are a lot of researchers who suggest that raising the RDA to between 100 and 200 mg would be a great way for people to get the antioxidants that they need to maintain overall well being even though the current RDA for Vitamin C is stuck at 60 mg.
When you are purchasing vitamins and supplements, you need to be careful. Whole food vitamins or vitamins with their co-factors, are much more effective than isolated nutrients and this was shown in research. Nutrition can be defined as a complex process of thousands of chemical reactions within our bodies. Vitamins are always better in their natural state – in the foods we eat. Using supplements in place of a poor diet is not a good idea.
In order to supplement an already good diet for the times you can’t get everything you need at meal time, the smart choice is to look for whole food vitamins.
