Exploring causal correlations between oily fish intake and multiple sclerosis: A two-sample Mendelian randomization study.

Key Points

• This research aims to investigate the causal relationship between oily fish intake and the risk of multiple sclerosis (MS).
• Conducted a two-sample Mendelian randomization analysis.
• Analyzed dietary patterns related to oily fish intake in relation to MS risk.
• Focused on individuals of European ancestry to assess correlations.
• Found a significant association between higher oily fish intake and a reduced risk of multiple sclerosis.
• Indicated that dietary patterns play a crucial role in MS risk among the population studied.
