摘要： Recently, pectin has been used as an alternative for commercial prebiotic products to modulate gut microbiota. In this study, the standard diet (Chow group) and high fat diet containing 0% (HF group), 1%, 3%, 5%, 8% or 12% (m/m) apple pectin (HF-P group) were offered ad libitum for 8 weeks to 4-week C57BL/6J mice (n = 10/group). Results showed that body weight gain (R-2 = -0.990), subcutaneous adipose accumulation (R-2 = -0.930), serum triglyceride elevation (R-2 = -0.879), acetate (R-2 = 0.955) and propionate concentration reduction (R-2 = 0.985) were suppressed by pectin from 1% to 12%, indicating dose response to pectin consumption. Moreover, abundance of obesity-related bacteria Coriobacteriaceae, and pectin-degradating bacteria, Faecalibaculum, Ruminococcus R-2 were 0.936, 0.963 and 0.937, respectively. Besides, attenuations for colonic injury and liver steatosis were observed after adding 5% and 8% obesity by modulating gut microbiota and enhancing short-chain fatty acids production.
