I predict one or more new studies, which are really just skewed surveys of other studies, will soon be forthcoming warning about the dangers of vitamins after that one! You watch - it NEVER fails to happen.
Now, here is the kicker: I wonder how much better the results would have been if it compared those who took high quality multi-vitamins derived from whole food and natural sources at amounts high enough to insure that they got optimum daily amounts of all the vital nutrients they needed instead of synthetic petro chemical vitamins and crushed rock minerals?
