Multivitamins in postmenopausal women: One doctor’s view of the WHI study

The conclusion from the Women’s Initiative Study that multivitamins don’t prevent cancer, heart disease or overall mortality troubles me for some reason.
Don’t get me wrong, I love the Women’s Initiative Study. It involves a large group of women (161, 808) followed over a long period (eight years in this instance.) Statisticians analyze the tons of data known about this group and report the findings. The data doesn’t care what I or anyone else thinks. It is what it is.
In the comment section of this report the author cites two other good, long-term women’s studies that showed an association between multivitamins and decreased colon cancer. It took 10 years in one group and 15 years in the other to start seeing a decrease.
But that’s not what bothers me. It’s not the study itself, but that people might get the idea no one needs vitamins. I mean, the New York Times has an article entitled “Vitamins; A False Hope?” This was a study on multivitamins, in set doses. It concluded nothing about set groups of individuals needing specific vitamins at other dosages.
