Alcohol-producing gut bacteria could cause liver damage even in people who don't drink
Non-alcoholic fatty liver disease (NAFLD) is the build-up of fat in the liver due to factors other than alcohol. It affects about a quarter of the adult population globally, but its cause remains unknown. Now, researchers have linked NAFLD to gut bacteria that produce a large amount of alcohol in the body, finding these bacteria in over 60% of non-alcoholic fatty liver patients. Their findings, publishing September 19 in the journal Cell Metabolism, could help develop a screening method for early diagnosis and treatment of non-alcoholic fatty liver.
"We were surprised that bacteria can produce so much alcohol," says lead author Jing Yuan at Capital Institute of Pediatrics. "When the body is overloaded and can't break down the alcohol produced by these bacteria, you can develop fatty liver disease even if you don't drink."
I guess the ultimate irony would be if drinking alcohol killed some of these unhealthy alcohol making bacteria.
