Influence of fish consumption on multiple sclerosis risk

Takeaway

  • Low fish consumption is associated with an increased risk of developing multiple sclerosis (MS); this is a separate risk factor from low sun exposure or low vit D but is synergistic to MS-associated genes.

Why this matters

  • Many environmental and genetic factors are associated with increased risk of MS; however the extent of the risk and association between the factors need further investigating.

  • Fish consumption and sun exposure are sources of vit D which is strongly correlated with reduced risk of MS; the results from this study show that increasing fish consumption could be a preventative measure, especially for those at increased genetic risk of MS, but the protective effect is not mediated by vit D.
