Tough Pill To Swallow

By  | 

A newly-published editorial about vitamins is getting a lot of attention.
The controversial piece -- in this week's Annals of Internal Medicine -- claims that dietary supplements and vitamins are a waste of money.
The editorial -- which is based on three studies -- says taking supplements offers no benefit when it comes to preventing cardiovascular disease, cancer, or a second heart attack.
It says those studies also show that multi-vitamins don't prevent mortality or improve cognitive function in men older than 65.
But an expert on nutrition says those in the study lived healthier lifestyles than the average american-- that most Americans don't have a healthy diet, and therefore don't get the vitamins and minerals they need.
The National Products Association -- which represents vitamin manufacturers and retailers -- responded by saying that multi-vitamins address people's nutritional deficiencies, but are not quote "the answer to all life's ailments, as the editorial suggests."
More than half of all adults in the United States take a multi-vitamin-- making it a 12-billion-dollar-a-year business.
