Are Multivitamins Useless Afterall?
Multivitamins and Pills
Millions of Americans spend billions of dollars on vitamins to boost their health. Research has focused on cancer and heart disease in particular because of evidence that diets full of vitamin-rich foods may protect against those illnesses. But that evidence doesn’t necessarily mean pills are a good substitute.
The study’s lead author, researcher Marian Neuhouser of the Fred Hutchinson Cancer Research Center in Seattle, offered this advice: “Get nutrients from food. Whole foods are better than dietary supplements,” Neuhouser said.
The study appears in Monday’s Archives of Internal Medicine.
Co-author Dr. JoAnn Manson said despite the disappointing results, the research doesn’t mean multivitamins are useless.
For one thing, the data are observational, not the most rigorous kind of scientific research. And also, it’s not clear if taking vitamins might help prevent cancers that take many years to develop, said Manson, chief of preventive medicine at Harvard’s Brigham & Women’s Hospital.
She said multivitamins may still be useful “as a form of insurance” for people with poor eating habits.
The study involved an analysis of data on women in their 50s and up who participated in long-running government studies on postmenopausal women. Almost 42 percent of the women said they used multivitamins regularly.
If you take multivitamins, do you feel the help you? What has your doctor said?
