New study says too many vitamins can cause cancer

Taking vitamins in too-high doses can cause cancer, according to new research presented at the annual meeting of the American Association for Cancer Research.

The findings surprised Dr. Tim Byers, of the University of Colorado Cancer Center.

"We found that the supplements were actually not beneficial for their health. In fact, some people actually got more cancer while on the vitamins," Byers said in a news release.

One study Byers cited found that too much folic acid, widely recommended as a supplement for pregnant women, had the opposite of its intended effect: It increased the number of polyps in a colon, which can develop into cancer.

In another study, taking more than the recommended dose of beta carotene increased the risk of lung cancer and heart disease by 20%.

"At the end of the day, we have discovered that taking extra vitamins and minerals do more harm than good," Byers said.

There is no substitute for a healthy diet, Byers said, and many people who take dietary supplements may not need them.

Well, how high is too high? At least some values should have been provided as a guide.
