Nutrition, microbiome and multiple sclerosis. Current knowledge from basic research and clinical practice

Epidemiological data indicate a disproportional increase in the incidence of multiple sclerosis (MS) over the last decades, particularly in industrialized countries. Although this increase is also associated with altered diagnostic criteria and improved sensitivity of imaging procedures, current data suggest that particularly alterations in our way of life play an important role. In recent years the importance of the gut and intestinal microbiome for some neurological diseases and in particular for MS was recognized. Because nutritional habits have a substantial influence on the composition of the microbiome and our nutrition has changed considerably in the last decades, nutritional components can play an important role in the pathogenesis of MS. In this further education article we summarize the currently available evidence on the role of the gut and on the effects of dietary components on the microbiome in the pathogenesis of MS.
