Got milk? You have to say might more than today's food labels a few cups to get adequate vitamin D for strong bones. But don't go overboard: long-awaited new dietary guidelines say there is no evidence that megadoses prevent cancer or other diseases - to thwart backers of the so-called sunshine vitamin.
The decision by the prestigious Institute of medicine the health arm of the National Academy of Sciences, could put some brakes on the nation vitamin D craze, warning that super high level could be risky.
"More is not necessarily better" shows Dr. JoAnn Manson of Harvard Medical School, who the Institute of medicine's report released Tuesday co-authored show.
Most people in the United States and Canada - from age 1 to the age of 70 - need, more than 600 international units vitamin D a day for the preservation of health, the report found to consume. People in the 70's and older need as much as 800 IUs. The report set these layers as "recommended dietary allowance" for vitamin d.
This is a bit higher than today's governmental food labels, and higher than 1997 recommendations by the Institute of medicine, range goal of 400 IUs from 200 to 600 IUs, depending on age set.
But it is far less than 2,000 IUs a day that some scientists on studies that suggest recommend, are people with low vitamin D at increased risk for certain types of cancer or heart disease show.
"This is a stunning disappointment," said Dr. Cedric Garland from the University of California, San Diego, who was not part of the Institute study, says, could in particular cut the risk of colorectal cancer if people consumed adequate vitamin d.
"Did you go far enough?" I think probably not, but it is a step in the right direction, "Prominent vitamin D researchers Dr. Michael Holick from Boston University Medical Center, who said the new levels needed attention to the vitamin D debate and promote more food fortification added."
Vitamin d and calcium hand in hand, and you've got a life of both to build and maintain strong bones. But the two-year study by the Institute of Medicine of the expert group Castle study of vitamin D is possible roles in other diseases in conflict. Some studies show no effect, or even signs of damage.
