New IOM Report Fails To Spot Vitamin D Deficiency In North America

This opinion piece asserts that the Institute of Medicine's (IOM) findings that there is no vitamin D deficiency in Canada and the United States highlights the IOM's failure to adequately update its Dietary Reference Intakes (DRIs) report for vitamin D and calcium. The author claims that the report is limited by the exclusion from the Committee of the most productive vitamin D researchers; an excessive reliance on clinical trials; exclusion of data supporting the conclusion that dietary deficiencies exist among significant parts of the population; and too much emphasis on vitamin D's impact on bone health.
