Multivitamins: Maybe a scam?
Maybe scam is too strong a word... or is it?
We should ask a lot more questions before spending money on multivitamins. Maybe we've just been conditioned to buy something that many of us may not need.
Several studies suggest that consumers believe that taking a multivitamin promotes health and can prevent some common diseases, but the evidence for both is "quite thin," said the panel's chairman, J. Michael McGinnis, senior scholar at the National Academy of Sciences' Institute of Medicine. Some of the evidence had conflicting results. For example, studies found a clear protective benefit against lung cancer for those who eat a diet rich in fruit and vegetables. But when Scandinavian scientists gave study volunteers beta carotene, commonly found in orange-colored fruit and vegetables, the risk of lung cancer in smokers increased.
