Multiple Sclerosis and Gut Microbiome Diversity in Mice: Diet Quality Associations

A study compared 288 cases of multiple sclerosis (MS) with 274 healthy controls, finding that better diet quality (measured by HEI-2015 scores) was linked to greater gut microbiome diversity. Additionally, MS participants reported higher total fruit intake and a significant association was observed between whole grains consumption and clinical disability (EDSS) scores.

Why it matters

These findings suggest that diet quality may influence gut microbiome diversity in MS, potentially affecting clinical outcomes. Understanding gut microbiome dynamics could be important in MS research.

What this does not prove

This cross-sectional study does not prove causation between diet quality, gut microbiome diversity, and clinical disability in MS patients.

Next milestone

No next milestone was established from the available source.

findingsHigher HEI-2015 scores were positively associated with greater Shannon alpha diversity (β=+0.077/10-unit increment; 95% CI: +0.003 to +0.150; p = 0.042).
