InfoAging is reprinting a couple of items on the recent government study on the effectiveness of vitamins. The mainstream press didn't emphasise that this was a narrow, short single study. In short, the results aren't all that useful or meaningful unless repeated in a lot more studies. It's always best to take a wait and see approach to recent research. The results in this study related to smoking are odd: if you want to lower your cancer risk, quit smoking, not taking vitamins!
