A study by researchers at the Harvard School of Public Health in Boston, studied a sample of 257 patients with Multiple Sclerosis (MS) out of a sample of over 7 million U.S. military personnel. Serum samples were analyzed for vitamin D levels, and the findings showed that the risks of MS fell 62 percent for those in the top fifth of vitamin D concentration among white people who comprised most of the study population. Besides promoting the absorption of calcium in the body, vitamin D also seems to act as a regulator of the immune system. (source: Reuters News Dec. 19, 2006)
[Ed. note: The body produces vitamin D after exposure to sunlight, but since not many foods are naturally rich in vitamin D, supplementation is often recommended.]
