Our Viking Inheritance?

RESEARCHERS working on the island of Sicily recently discovered that Enna has an unexpectedly high and rising incidence of MS¹. This, in the warm wine/oil-growing region of the Mediterranean where the incidence of MS is supposedly lower than in northern Europe. It was Dr. Roy L. Swank, MD Ph.D in his book based on years of study, research and experience with MS patients who noticed that is was the beer-drinking, bread-eating people of northern Europe who were more susceptible to the disease and he suggested the problem was possibly due to their wheat-based diet. But is there another reason?
