The Claim

Dietary intake patterns account for a greater proportion of variation in cardiometabolic health markers than the gut microbiome, with unique dietary contributions explaining a median ΔR² of 0.152 compared to 0.006 for the gut microbiome, indicating that diet influences cardiometabolic health through pathways independent of microbial mediation.

In plain English

Dietary patterns explain more differences in heart and metabolic health markers than the gut microbiome, with diet accounting for 25 times more variation than microbial factors alone.

See the scientific wording

Dietary intake patterns explain a larger proportion of variation in cardiometabolic health markers than the gut microbiome itself, with unique diet contributions explaining a median ΔR² of 0.152 compared to 0.006 for the microbiome, suggesting diet may influence health through pathways beyond microbial mediation.

Why this might work

What you eat gets broken down into chemicals that go straight to your liver and fat tissue, changing how they process sugar and fat, which directly affects blood sugar, cholesterol, and inflammation levels without needing gut bacteria to be involved.
