Now Antioxidants Are Bad?

Posted May 13 2009 11:33pm
"They" have been telling us to supplement the diet with antioxidants, such as vitamin C and vitamin E, for years. Now, research presented this week in The Proceedings of the National Academy of Sciences, suggests these supplements may interfere with some of the benfits you are supposed to derive from daily exercise.
New research shows that preventing diabetes through exercise -- recommended by all physicians -- might be harder when exercisers also take antioxidant supplements like vitamins C and E.

It sounds counterintuitive. During exercise, muscle cells metabolize glucose. That causes tissue-damaging oxygen molecules to be released. Antioxidants are thought to be good for you because they attack those molecules. But according to the study, by scientists at the University of Jena in Germany, those "free radical" molecules seem to increase the body's sensitivity to insulin and hence may stave off Type II diabetes.

This will be controversial, at least for awhile. Hopefully, it doesn't turn into a situation that has been seen with coffee -- good one week and bad the next.
