New Study Questions Anti-Oxidant Benefits

(Editor: while the dissenting opinions from this study are buried in the middle of the article, the following quote should be highlighted:

"This latest report is not without criticism. Experts questioned why the reviewers included only studies in which someone died; 405 death-free trials were excluded from the analysis. Among the studies that were included, most looked at the effect of antioxidant supplements in people with existing disease, rather than healthy populations. (It's possible that antioxidant nutrients may be beneficial before disease has been established".

This seems to be a pretty big caveat.)

Antioxidants, widely touted to ward off heart attacks, cancer, even Alzheimer's disease, were once again called into question last week.

A review of 67 randomized controlled studies concluded that antioxidant supplements do not extend life and some - vitamins A and E and beta carotene - could even cause premature death.

Antioxidant nutrients such as vitamins C and E, beta carotene and selenium are thought to help counter damage caused by free radicals, unstable oxygen molecules that can harm cells and lead to chronic disease.
