Important new evidence of a genetic link between vitamin D deficiency and multiple sclerosis
Did our hunter gatherer ancestors suffer from vitamin D deficiency? Unlikely, if they spent most of their time outdoors foraging for food without much clothing. For man in the 21st century, it might be easier to take a vitamin D supplement, especially those individuals who have a genetic predisposition to vitamin D deficiency.
According to the Department of Health, more than one in five people have low levels of vitamin D which only occurs naturally in a few foods, such as oily fish and eggs. The best source of vitamin D is sunlight.

Lack of vitamin D may cause multiple sclerosis, study finds
Researchers say findings may have important public health implications as vitamin supplements are relatively safe and cost-effective
Lack of vitamin D may be a direct cause of multiple sclerosis (MS), a study has found. The discovery may have important public health implications since so many people have insufficient levels of the essential vitamin, researchers say.
The findings may help explain why rates of MS, a potentially disabling auto-immune disease that damages nerve fibres, are higher in high-latitude regions such as northern Europe, which have fewer sunny days. Sunshine triggering a chemical reaction in the skin is the primary source of vitamin D.
