2. Vitamin D level during age 0-1 #infant correlates with #bodyWeight #obesity later on. https://pjmedia.com/instapundit/411017/

Analysis: Is there nothing it can't do.

Caveat first that childhood IQ does not correlate well with adult IQ.

We generally do not think of Vitamin D as having anything to do with the neural system. So this study is very interesting. Perhaps the IQ effect comes from the #immuneSystem effects / #allergy's. Or the supposed effect on cell #differentiation.

Given that skin #melanin level correlates with Vitamin D deficiency in America, perhaps this explains some of the IQ #achievementGap. But given the noisy signal of childhood IQ, it is likely the adult effect is low.

We see here too that allergies, a known effect of Vitamin D deficiency, correlates with obesity.
