RESUMO
Consumption of a high-fat diet (HFD) is associated with an increased risk of metabolic diseases, cancer, and neurological disorders, which are major global health concerns. In the present study, mice were fed a HFD containing 40% fat and 0.5% or 1.0% acylated steryl-ß-glucosides (ASG) and their gut microbiota was compared to that of mice fed with a low-fat diet (LFD). After 55 d, the epididymal fat weight was higher in the HFD and ASG groups than in the LFD group; however, the epididymal fat weight was lower in the ASG group than in the HFD group. The abundance of gut microbiota increased with HFD in obese micespecific Bacillota, but decreased when ASG was added to the HFD. The number of intestinal bacteria involved in the production of carcinogenic secondary bile acids was increased by the consumption of HFD, but decreased by the addition of ASG to HSD. This finding may indicate the gut bacteria-mediated health benefits of ASG.
