Dietary changes in temporal relation to multiple sclerosis in the Faroe Islands: an evaluation of literary sources

In order to generate additional hypotheses on a possible role of dietary factors in the etiology of multiple sclerosis, the ethnographic literature and other relevant sources from the Faroe Islands were reviewed. A transitory occurrence in the first half of the 20th century was evident for the extended consumption of oat products, of fulmars possibly infected with ornithosis virus, and of foodstuffs treated with wood smoke or smoke condensates. The hypothetical basis of these considerations must be emphasized.
