…that we recently highlighted here after the JAMA editorialized about the stupid American public’s ongoing use of them. The scholarly publication — with absolutely NO ties to the drug industry — again warned us about the dangers and waste in their use a few weeks ago very likely because the pharmaceutical folks would love to get their hands on the money from their sales. So let’s demonize them first, regulate them, then take them over when hundreds of small supplement companies cannot possibly afford to deal with the newly created regulatory environment.
But there are of course reasons — literally thousands of them — to study, purchase, and support good health with them. A couple of weeks ago a rather astonishing study was published in a scholarly Australian medical journal strongly suggesting that monitoring and maintaining vitamin D levels at or above 25 ng/dL yields a 60% reduction in autistic behaviors by the age of 6.
Compared with the 25OHD sufficient group (25OHD>50 nmol l−1), those who were 25OHD deficient had significantly higher (more abnormal) SRS scores (mid-gestation n=2866, β=0.06, P<0.001; cord blood n=1712, β=0.03, P=0.01). The findings persisted (a) when we restricted the models to offspring with European ancestry, (b) when we adjusted for sample structure using genetic data, (c) when 25OHD was entered as a continuous measure in the models and (d) when we corrected for the effect of season of blood sampling. Gestational vitamin D deficiency was associated with autism-related traits in a large population-based sample. Because gestational vitamin D deficiency is readily preventable with safe, cheap and accessible supplements, this candidate risk factor warrants closer scrutiny.
Imagine that! Well, we should respect those Aussies because, after all, they did discover a major cause of stomach ulcers (Helicobacter pylori), and they are turning the inflammatory bowel disease world on its head with the idea — seems to be more than that actually — that Crohn’s disease is caused by a bacterium similar to Tb. But here, they have identified a simple, risk free intervention with a potential to reduce autism risks by 60%! Also, remember that low vitamin D states tend to make the system’s reaction to viruses (and vaccines) much more violent.
One would think this would be big news for JAMA. We will wait for the next editorial.
