Abstract Title:
Green tea polyphenols decrease weight gain, ameliorate alteration of gut microbiota, and mitigate intestinal inflammation in canines with high-fat-diet-induced obesity.
Abstract:
Green tea polyphenols (GTPs) exhibit beneficial effects towards obesity and intestinal inflammation; however, the mechanisms and association with gut microbiota are unclear. We examined the role of the gut microbiota of GTPs treatment for obesity and inflammation. Canines were fed either a normal diet or high-fat diet with low (0.48% g/kg), medium (0.96% g/kg), or high (1.92% g/kg), doses of GTPs for 18 weeks. GTPs decreased the relative abundance of Bacteroidetes and Fusobacteria and increased the relative abundance of Firmicutes as revealed by 16S rRNA gene sequencing analysis. The relative proportion of Acidaminococcus, Anaerobiospirillum, Anaerovibrio, Bacteroides, Blautia, Catenibactetium, Citrobacter, Clostridium, Collinsella, and Escherichia were significantly associated with GTPs-induced weight loss. GTPs significantly (P
