Link between vitamin D and dementia risk confirmed
I see at the end of the article there's a link to a report about low vitamin D and schizophrenia too. The correlation of it to mental health is rather interesting, and perhaps a bad sign for the future health of oldies in 70 years time, given the somewhat over the top concern about sun exposure and kids we seem to now have.
I wonder if anyone has ever surveyed dementia risk amongst life long nudists? Googling the topic doesn't immediately come up with useful results, partly because there seems to be some program called NUDIST which is used in dementia research.

Vitamin D plays a very important role in preventing excessive inflammation. Additionally it's role in calcium regulation is important for the brain because calcium dysregulation is a key feature in aging. HOWEVER, vitamin D alone is not enough, MUST have good sources of Vitamin K, especially K2 types.
The schizophrenia linkage is weak and may have more to do with the pregnancy than the child; though in relation to Multiple Sclerosis low Vitamin D levels, especially in adolescence is also implicated.
Sunlight exposure is the best but it is important to remember that it must be exposure at the right time of day because UVB does not readily reach the surface of the earth. So in winter Aus between 10.00am and 2.00pm is good.
