Multivitamin

There is limited evidence that multivitamins may help prevent breast cancer, and an NIH panel in 2006 wasn't convinced that popping the pills was worth it. Neither is the Agency for Healthcare Research and Quality, which said the only benefit could be to reduce cancer risk in people with poor nutrition. And a large 2009 study failed to find any beneficial effects of the vitamins for cancer or deaths among postmenopausal women.

Bottom line: Multivitamins aren't a bad idea if "you're on the go," Anderson says. "But don't expect major lifesaving benefits."
