An international team of medical researchers has found that people who regularly drink coffee have much higher levels of a certain type of gut bacteria than those who do not.

The link between coffee and gut microbiota
According to Medical Xpress , in a paper published in the journal Nature Microbiology , the research team analyzed stool and blood samples from a large number of patients, and also studied similar data in major medical databases to find out the impact of coffee drinking on the gut microbiome.
Previous studies have shown that food and beverage consumption influences the gut microbiome, which is the community of fungi, yeasts and bacteria that live in the human digestive tract. However, which foods benefit this microbiome and which harm it remains poorly understood.
In the new study, the team looked at the effects of a single food, or in this case, a beverage, on the gut microbiome. They chose coffee for two reasons. First, it is widely consumed. Second, coffee is often consumed daily or not at all.
Foods or drinks that significantly impact the gut microbiota
To investigate the effects of coffee drinking on gut microbiota, researchers began by analyzing medical data from about 22,800 people living in the UK and US, along with data from 54,200 people in 211 study groups.
This allowed them to compare stool sample data from those who reported drinking coffee and those who did not, and explore differences in gut microbiota between the two groups.
The researchers found one big difference between the two groups – the amount of the bacteria Lawsonibacter asaccharolyticus . Regular coffee drinkers had eight times more of this bacteria than non-coffee drinkers, and this difference was consistent across the globe.
The researchers admit they don't yet know what effect high levels of L. asaccharolyticus have on humans, but suggest it may be linked to the health benefits already noted in coffee drinkers.
They also suggest that single foods or beverages can have a significant impact on the human gut microbiota.
