Coffee drinkers have more of one type of gut bacteria

The study discovered that regular coffee drinkers have a significantly higher amount of a specific type of gut bacteria, Lawsonibacter asaccharolyticus.

To investigate coffee’s impact on the gut biome, researchers analyzed medical data from approximately 22,800 individuals in the UK and the US, as well as 54,200 individuals in 211 cohorts.

The researchers observed that levels of this bacteria in regular coffee drinkers were up to eight times higher than in non-drinkers, a trend observed globally.

The health consequences of higher L. asaccharolyticus levels are still unknown

The researchers noted that the health consequences of higher levels of L. asaccharolyticus in humans remain unclear.

But they suggested it could be associated with the health benefits typically associated with regular coffee consumption.

The finding highlights the potential impact of a single food or drink on the human gut biome, an area that needs further exploration to understand the effects of diet on gut health.
