Effects of γ-aminobutyric acid-rich fermented rice bran on hepatic histology, gut microbiota, and fecal metabolites in a rat model of high-fat diet-induced NAFLD-like hepatic injury.
γ-Aminobutyric acid (GABA)-rich fermented rice bran (GFRB) is a multi-component fermented food matrix with potential metabolic benefits, but its effects on high-fat diet (HFD)-induced liver injury and associated gut microbial and metabolic changes remain unclear. In this study, we characterized the metabolite profile o...
