Gut gene may reveal Who's at risk from red meat
NCT ID NCT05980884
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at why some people have higher heart disease risk from red meat than others. It focuses on a gut bacteria gene called gbu that helps turn carnitine (found in red meat) into TMAO, a compound linked to heart problems. Researchers will test blood and stool samples from 230 adults to see if the gbu gene can predict TMAO levels after eating carnitine. The goal is to better understand individual differences in heart risk, not to test a treatment.
