“Non”alcoholic fatty liver.

It’s been hiding the booze in plain sight. This fascinating basic science work demonstrates that a commensal strain of Klebsiella pneumoniae endogenously produces surprisingly high blood alcohol levels, continually coursing through the veins of those where the bug sets up shop, with levels heightened even further after high-fat and/or high-carb loads. Not only was the strain found in the majority (26/43) of patients with NAFL tested, it worked to produce NAFL when introduced to mice. | Yuan, Cell Metab 2019
