New Gut Science: The Bacteria That Keep Your Heart Healthy
Prof. Nicola Segata reveals results from analyzing 34,000+ microbiomes: 50 gut bacteria are strongly linked to health outcomes. Three powerful 'good bugs' suppress pathogenic bacteria and predict cardiovascular, metabolic, and immune health.

Segata: analysis of 34,000+ microbiomes identified 50 bacterial species strongly linked to health. The top 'good bugs' (including Faecalibacterium prausnitzii) produce butyrate, reduce inflammation, and actively suppress pathogenic bacteria.
Highlights
•
Gut bacteria produce metabolites that directly affect cardiovascular health
Segata: certain gut bacteria produce trimethylamine N-oxide (TMAO) from choline and carnitine, which promotes atherosclerosis. Others produce butyrate and propionate, which reduce blood pressure and improve cholesterol profiles.Was this useful?
