retrospective study published in this month's Journal of Clinical Endocrinology & Metabolism , that a U shaped curve demonstrated an increase risk for acute coronary syndrome (heart attack) & cardiac mortality in those w/25OH vitamin D less than 20ng/dL. Interestingly, the sweet spot for 25OH vitamin D was just 20-32ng/dL, with any level about 32ng/dL also being associated w/ACS & cardiac mortality. Of course, the editorialists had a field day picking apart the study .Therefore, it shouldn't come as a surprise in a

Leave your mind open to new (interpretation of) data. And avoid listening to those 30 second sound bites that poorly summarize complicated studies.
