Polyphenol- and Caffeine-Rich Postfermented Pu-erh Tea Improves Diet-Induced Metabolic Syndrome by Remodeling Intestinal Homeostasis in Mice.

ABSTRACT: Postfermented Pu-erh tea (PE) protects against metabolic syndrome (MS), but little is known regarding its underlying mechanisms. Animal experiments were performed to determine whether the gut microbiota mediated the improvement in diet-induced MS by PE and its main active components (PEAC). We confirmed that PE altered the body composition and energy efficiency, attenuated metabolic endotoxemia and systemic and multiple-tissue inflammation, and improved the glucose and lipid metabolism disorder in high-fat diet (HFD)-fed mice via multiple pathways. Notably, PE promoted the lipid oxidation and browning of white adipose tissue (WAT) in HFD-fed mice. Polyphenols and caffeine (CAF) played critical roles in improving these parameters. Meanwhile, PE remodeled the disrupted intestinal homeostasis
