1 in 5 kids get little vitamin D, study says

This article from this morning's Charlotte Observer states that 20% or more children under age 11 do not get adequate amounts of Vitamin D. Actually, I would be surprised if its ONLY 1 in 5 children-----Vitamin D deficiency is rampant in our society. I think right now one of the biggest problems (for both big and little people) is that there is absolutely no concensus about how much Vitamin D is needed. It is becoming clear that the old recommendations of 400-600 IU's is woefully inadequate, but I've heard recommendations ranging anywhere from 1000-5000 IU's daily (I take 5000 IU's under a doctors supervision-----always check with your own practitioner.)
