12 Jul 2017 --- A new study reports that feeding mice a Western diet, which is high in fat and sugar, resulted in hepatic inflammation, especially in males. Moreover, liver inflammation was most pronounced in Western diet-fed male mice that also lacked farnesoid x receptor (FXR), a bile acid receptor. The study is important because it links diet to changes in the gut microbiota as well as bile acid profile, pointing to the possibility that probiotics and bile acid receptor agonists may be useful for the prevention and treatment of hepatic inflammation and progression into advanced liver diseases.
