The Claim

In patients with ST-elevation myocardial infarction, polyphenol supplementation is associated with a reduction in the abundance of Parabacteroides goldsteinii and Lactobacillus salivarius, microbial taxa previously associated with trimethylamine N-oxide production and lipid metabolism.

In plain English

In patients who have had a heart attack called STEMI, taking polyphenol supplements is linked to lower levels of two gut bacteria, Parabacteroides goldsteinii and Lactobacillus salivarius, which have been connected to the production of trimethylamine N-oxide and lipid metabolism.

See the scientific wording

In STEMI patients, polyphenol supplementation is associated with a decrease in the abundance of Parabacteroides goldsteinii and Lactobacillus salivarius, taxa previously linked to TMAO production and lipid metabolism, suggesting a selective suppression of potentially detrimental microbes.

Why this might work

Polyphenols feed beneficial gut bacteria that make butyrate, which strengthens the gut lining and outcompetes harmful bacteria that produce TMAO. This stops TMAO from rising in the blood, reducing damage to the heart and blood vessels.

  1. Study: Polyphenol-mediated microbiome modulation in STEMI patients: a pilot study

    In heart attack patients, taking polyphenol supplements lowered one harmful gut bacterium (Parabacteroides goldsteinii) and kept a dangerous blood chemical (TMAO) from rising, which suggests the supplements may help by cleaning up bad gut bacteria linked to heart disease.
