Most of us are probably or definitely vitamin D deficient. A small amount of vitamin D, easy to obtain from a normal diet, prevents the short-latency deficiency disease rickets. But even the healthiest diet won't provide the far higher amounts that are now believed to play a part in maintaining health at every life stage. Multiple and congruent findings, mostly involving population studies, on the role of vitamin D deficiency in diabetes, mortality and morbidity in the intensive care unit, pulmonary disease, mood disorders and cognitive impairment, vascular disease, multiple sclerosis, and cancer, substantiate the recommendation that higher vitamin D plasma levels than previously believed are needed for health maintenance. The Institute of Medicine recently tripled its vitamin D RDA, but this was too conservative according to other experts who call for a tenfold or greater increase. For some, the crux of this moment in nutrition research is that the clinical trial has shown its limitations in research with single nutrients that work in combinations with other nutrients in the body. For others, controlled clinical trials are the fundamental need at this juncture because only they can provide the kind of evidence that will guide clinicians, who deal with individuals, and public policy makers, who deal with groups. How much evidence is enough, for whom? How much vitamin D is enough, for whom? The purpose of this special issue is to provide an update on this protean health-promoting steroid hormone, the heretofore lowly vitamin D.
