I was reading a study on the impact of milk intake by pregnant women on birth weight of babies. The study itself was mildly interesting, but the later aspects of the report caught more of my attention:
The study emphasizes how little scientists know about the biological roles vitamin D plays or how much we should be getting, said Bruce W. Hollis, Ph.D., and Carol L. Wagner, M.D., both of the Medical University of South Carolina in Charleston, in an editorial.
The currently suggested adequate vitamin D intake, proposed by the Institute of Medicine in 1997, is 200 international units (5 micrograms) for children and adults up to age 50, including pregnant women, Drs. Hollis and Wagner noted.
However, this recommendation is "based on a report issued four decades ago by an expert committee on vitamin D that provided only anecdotal support for what it referred to as 'the hypothesis of a small requirement' for vitamin D in adults," they said.
How is it that we continue to give advice that is not drawn from scientific study in a field filled with scientists?
