The Big Vitamin D Mistake
This is fake news. I'll explain why I think so. Please counter me if I'm wrong.<p>>>This piece of news is a literal "copy-paste" of the abstract of the article "Big Vitamin D Mistake - BVDM"<p>BVDM is an article published by a Greek group. About the population from Finland.<p>BVDM has 2 premises and 2 conclusions.<p>>Premise 1: There is a correlation (not causation) reported recently in Finland of country-wide vit. D supplementation and lower Diabetes Mellitus type 1 incidence.
>Premise 2: There was a study published in America (Meta Analysis of All Cause Mortality and Vitamin D - MAACVD) that investigated deaths that had the lab values of vitamin D available. The main finding of the study was: Vit. D levels of >30ng/mL is probably better than <9ng/mL, correlated with a lower risk of death (hazard ratio of 1.6 to 2.2).*<p>THESE ARE THE PREMISES AND NO MORE. Here are their magical conclusions:<p>>Conclusion 1: The right level of vitamin D is 100ng/mL.
This is apparently extrapolated from a subgroup analysis in MAACVD. I find this extrapolation shocking because: 1- this finding wasn't considered significant enough to be published in the abstract by the original American group. 2- subgroup analyses shouldn't be extrapolated.
>Conclusion 2: in order to make sure everyone gets this alleged "correct vit. D levels", here are the doses of supplementation that everyone should get.<p>>> As you can see, the conclusions are far outside the realm of possibilities offered by the premises. What the Greek authors did was nitpick a couple of minor points in some random published studies and synthesize them into a magical conclusion of how much more Vit D everyone should take (more than 3x the current recommended amount in some ages).<p>This is sensationalism. I'm sorry to see such poor material to be presented as science by "scientists" and "scientific journals".<p>>>Please correct me if I'm wrong.<p>*PS: I wasn't able to read the MAACVD full article, it wasn't free online. In these kinds of articles, the axis of the study is presented in the abstract, and the most significant findings are never left out. If someone has access to the full text, please share it with me and this forum.
