Type 2 diabetes (T2D) is potentially linked to disordered tryptophan metabolism that attributes the intricate interplay among diet, gut microbiota, and host physiology. However, underlying mechanisms are substantially unknown. Comparing microbiome metabolome differences in mice fed a normal diet (ND) high-fat (HFD), we uncover microbiota–dependent metabolite 5-hydroxyindole-3-acetic acid (5-HIAA) present at lower concentrations with versus without insulin resistance. We further demonstrate...
