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.
