The Claim
In humans, specific gut bacterial taxa, particularly those enriched in the Prevotella enterotype, are associated with elevated plasma trimethylamine N-oxide (TMAO) levels and omnivorous dietary patterns, indicating that long-term dietary habits may shape a gut microbial community capable of producing TMAO.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
The kinds of gut bacteria you have, especially if you eat a lot of meat, might be linked to higher levels of a substance in your blood called TMAO, which could mean your diet over time helps shape which bacteria stick around.
See the scientific wording
Specific gut bacterial taxa in humans, including those enriched in the Prevotella enterotype, are associated with higher plasma TMAO levels and omnivorous dietary patterns, suggesting that long-term diet shapes a TMAO-producing microbial community.
What the research says
1 studyStudy: Intestinal microbiota metabolism of L-carnitine, a nutrient in red meat, promotes atherosclerosis
The study shows that people who eat meat have gut bacteria that turn a substance in red meat into a chemical called TMAO, which is linked to heart disease, and this supports the idea that long-term diet shapes these bacteria.
