Abstract
Alcoholic hepatic steatosis (AHS) is a common early-stage symptom of liver disease caused by alcohol consumption. Accordingly, several aspects of AHS have been studied as potential preventive and therapeutic targets. In this study, a novel strategy was employed to inhibit fatty liver accumulation and counteract AHS through the consumption of microorganism-fermented Protaetia brevitarsis larvae (FPBs). By using an AHS rat model, we assessed the efficacy of FPB by examining the lipid profile of liver/serum and liver function tests to evaluate lipid metabolism modulation. After FPB administration, the lipid profile-including high-density lipoprotein, total cholesterol, and total triglycerides-and histopathological characteristics exhibited improvement in the animal model. Interestingly, AHS amelioration via FPBs administration was potentially associated with poly-γ-glutamic acid (PγG), which is produced by Bacillus species during fermentation. These findings support the formulation of novel natural remedies for AHS through non-clinical animal studies, suggesting that PγG-enriched FPBs are a potentially valuable ingredient for functional foods, providing an ameliorative effect on AHS.
