摘要

高糖高脂饮食过量摄入导致脂肪蓄积从而形成肥胖,增加相关慢性疾病的患病率和死亡率。该研究通过膳食补充黑木耳,从而改善高脂饮食引起的小鼠脂肪堆积及肠道菌群紊乱。黑木耳经干燥并粉碎后添加到小鼠高脂饲料中,实验进行4周,每2 d称重1次,最后1周收集粪便以进行肠道菌群高通量测序。小鼠处死后取血清、肝脏、脾脏等进行测定。结果表明,膳食补充黑木耳能显著降低小鼠体重及血清中胆固醇和甘油三酯的含量,同时减少肝脏中的脂滴含量,且日常摄入黑木耳能有效减轻高脂饮食引起的肠道菌群紊乱。综上,膳食补充黑木耳能有效改善高脂饮食引起的小鼠肥胖、肝脏脂质堆积及肠道菌群紊乱。

Abstract

Auricularia auricula was added into the high-fat diets (HFD) of mice to ameliorate fat and gut microbiota dysbiosis. The experiment was carried out for four weeks and the mice were weighed on alternate day. Feces were collected for high-throughput sequencing in the last week. After executed, the serum, liver and spleen were collected for determination. The results showed that dietary supplementation of A. auricula significantly reduced the body weight, the content of cholesterol and triglyceride and the content of lipid droplets in liver. Moreover, daily intake of A. auricula effectively alleviated the disturbance of gut microbiota caused by HFD. In conclusion, dietary supplementation of A. auricula effectively ameliorated the obesity, hepatic lipid accumulation and gut microbiota dysbiosis of mice.
