Evidence is growing that vitamin D has a health impact that extends beyond its essential role in bone formation. e! Science News reports on data from a Finnish study of 3,000 people. This is interesting because humans get some vitamin D as a result of sun exposure, and Finns probably get less sun than any other group in the world. Anyway, compared to people with the highest blood levels of vitamin D, those with the lowest levels had triple the risk of Parkinson's.
Eat more fish and more fortified cereals and milk to get enough D. But no megadoses of the stuff.
