Effect of banana pulp dietary fibers on metabolic syndrome and gut microbiota diversity in high‐fat diet mice. Issue 9 (14th July 2020) - Wei, Guohua
Abstract: Banana ( Musa nana Lour .) have the effect of anti‐obesity and lipid modulating properties. However, the influences of banana pulp dietary fibers (BP‐DF) on metabolic syndrome (MetS) and gut microbiota (GM) are unknown. In this research, we explore a novel strategy for dietary BP‐DF on attenuation of lipid metabolic disease, GM disorder, and associated mechanisms in high‐fat diet (HFD) mice. BP‐DF can strongly suppress on HFD caused body weight and epididymal fat mass gain, and significantly improved serum lipid profiles, liver lipid profiles, and intestinal function. BP‐DF also significantly improved fecal short‐chain fatty acids formation and fecal ammonia content. BP‐DF impacted the intestinal microorganism at all kinds of taxonomic levels by increasing the proportions of beneficial Lactobacillus, Bacteroidales _S24_7_group, and Alloprevotella and decreasing the disease or obesity associated Sutterella, Streptococcaceae, and Erysipelotrichaceae . The experiments show that BP‐DF may use as a functional ingredient for preventing obesity, MetS, and intestinal microorganism imbalance. Practical applications: Obesity result in many metabolic complications, and it poses a great threat to people's health. Nowadays, the introduction of DF may lead to the development of a new strategy in the treatment of obesity and its metabolic syndrome. Our experiments findings show that BP‐DF may use as a functional ingredient for preventing obesity, MetS, and intestinal microorganism imbalance. Therefore, BP‐DF can be applied to the development and production of functional food, and can also be used as an important food functional ingredient, which can be added to various food, such as bread, noodles, baked goods, cakes, etc., to improve its nutritional value. Abstract : Nowadays, the introduction of DF may lead to the development of a new strategy in the treatment of obesity and its metabolic syndrome. Banana pulp dietary fibers (BP‐DF) caused strong inhibition on high‐fat diet caused body weight and epididymal fat mass gain, and significantly improved serum lipid profiles, liver lipid profiles and intestinal function by improving fecal short‐chain fatty acids formation and modulating the gut microbiota. BP‐DF may use as a prebiotic for preventing obesity, Mets and gut microbiota imbalance, and can be applied to the development and production of functional food.
