Coffee drinkers consistently harbor up to eight times more of a specific gut bacterium than nondrinkers, according to recent research.

The international study, which tracked the drinking habits of nearly 77,200 people across 25 countries, found that coffee consumption leaves a distinct microbial signature. Researchers can identify coffee drinkers with 95 percent accuracy by examining their gut bacteria alone.

How Your Brew Affects Gut Microbiome

A 2021 study established that coffee had the strongest correlation with microbiome composition among over 150 studied foods, notably affecting levels of Lawsonibacter asaccharolyticus in approximately 1,000 people.

The latest study by researchers from the CIBIO Department at the University of Trento in Italy and Harvard University, published in Nature Microbiology in November, aimed to deepen understanding of how coffee affects gut health.
