Researchers from McGill University in Canada divided the Europeans into two groups: one with a genetic predisposition to low vitamin D and the other without the predisposition, according to the new study published in the British journal PLoS Medicine. They then compared the prevalence of MS in the two groups.
Researchers said people genetically prone to lower blood levels of a marker of vitamin D had a higher risk of having MS than those without the predisposition.
Normally, people can get vitamin D through sunlight and various food sources, including oily fish, eggs, fortified breakfast cereals. But some people may not get enough.
