IOM Vitamin D Intake Recommendation Error Could Have Alzheimer’s Risk Consequences
Researchers at the UCSD and Creighton University at Omaha, Nebraska say the National Academy of Sciences (NAS) Institute of Medicine (IOM)'s Recommended Dietary Allowance (RDA) for vitamin D intake is miscalculated and underestimated -- not by any small measure, but by a whopping factor of ten. In a letter published this month in the journal Nutrients, the scientists explain that they've confirmed a calculation error in the IOS metrics that has been previously noted by other investigators, by factoring is a data set pertaining to a different population. In 2014, University of Alberta School of Public Health statisticians, Professor Paul Veugelers PDF, PhD, MSc and John Paul Ekwaru, published an Open Access paper entitled "A Statistical Error in the Estimation of the Recommended Dietary Allowance for Vitamin D" (Published: 20 October 2014 Nutrients 2014, 6(10), 4472-4475; doi:10.3390/nu6104472) in the online journal Nutrients showing that the Institute of Medicine (IOM) had made a major calculation error in its recommended dietary allowance (RDA) for vitamin D. Dr. Cedric F. Garland, Dr.P.H, an adjunct professor at UC San Diego's Department of Family Medicine and Public Health says his team was able to confirm findings last year reported by Dr. Paul Veugelers in Nutrients last October. The March, 2015 Nutrients letter's coauthors observe that using the same data set as had the IOM panel, investigators Veugelers and Ekwaru showed that the Recommended Dietary Allowance (RDA) for vitamin D had been underestimated by an order of magnitude, and an RDA of 8895 IU per day would have been appropriate, with the qualification that there was some uncertainty in that estimate, inasmuch as this value required an extrapolation from the available data, which did not includ
