    A A E Vinkhuyzen et al. Gestational vitamin D deficiency and autism-related traits: the Generation R Study, Molecular Psychiatry (2016). DOI:[/PLAIN] [Broken] 10.1038/mp.2016.213

    Interesting new study that indicates vitamin D is required for normal neurological development. It has been known for a long time that vitamin D (somewhat more like a hormone than a true vitamin, as it is not a co-enzyme constituent) is important for bone health, for example. Now it seems that dietary vitamin D is required during pregnancy. Direct sun exposure which creates vitamin D precursors in human skin was not recommended by the authors, because of skin cancer concerns.

    abstract:

    [IMO]
    For the US:

    This might be explanatory for the differential distribution of autism rates among populations in the US. 3.8% fat milk in the US is the only commercially available milk with added vitamin D. Because of the somewhat misplaced guidance about fat consumption, higher SES* women have tended to avoid whole milk.

    At the same time, they also inadvertently avoided getting extra vitamin D.

    Other sources of vitamin D are salmon, tuna, beef liver, egg yolks. Again, eggs were on the no-eat list for cholesterol reasons. Which advice has been largely reverted. Beef liver consumption in the US is minuscule. Mostly ends up in pet foods.

    This could help to explain why autism rates are higher in places where a lot of high SES women live. Silicon Valley is an example in the US. BTW there are good fatty acids in the diet, and they are required.

    Another reason to get that Vitamin D.

    :partytime: I will be feeling a little less guilty when I start tanning again!

    This may be because women with higher SES have children later than those with lower SES. There is a large body of evidence showing that the risk of autism increases with the mothers age at pregnancy. https://www.ncbi.nlm.nih.gov/pubmed/27858958

    There is no good way to test what I posited as an opinion, really. A nutrition researcher friend told me: 'Humans are the worst possible research subjects'
    Compound that with business interests messing with science: http://www.pbs.org/newshour/rundown/sugar-industry-artificially-sweetened-harvard-research/
    Not to mention the FUD attacks from the business lobby and political folks working to quash all kinds of other research that does not match their personal views.
    FUD: https://en.wikipedia.org/wiki/Fear,_uncertainty_and_doubt

    Note: the wiki article needs editing to remove some speculative stuff. Both sides of the FUD issue have problems it seems. .... what a surprise. The definition of the concept there is fine.
