The results of a study published in the Journal of the American Medical Association on the 20th December show that people with high levels of vitamin D - especially those under the age of 20 - have a two-thirds lower risk of developing MS compared with those with the lowest levels measured. As with other auto-immune diseases, MS is much more common amongst people who live in regions distant from the equator, where there is less sunlight. This study highlights the importance of sunlight exposure in regulating the immune system. It also confirms that vitamin D deficiency is an epidemic in the United States.
