Obesity is associated with an increased risk of metabolic abnormalities. The citrus fruit calamondin contains nobiletin and hesperidin, which are involved in lipid metabolism, and vitamin C, which is an antioxidant. We investigated the metabolic profiles of C57BL/6 mice fed a normal diet, high-fat diet (HFD), HFD + 1% (w/w) calamondin puree (HFD + CL1), or HFD + 5% (w/w) calamondin puree (HFD + CL5). Glucose tolerance was significantly higher in HFD + CL than in HFD-fed mice. Histological analysis revealed less lipid accumulation in the livers of HFD + CL-fed mice than in those of HFD-fed control mice. Hepatocyte ballooning and large lipid droplets – key non-alcoholic fatty liver disease characteristics – were observed in HFD-fed mice after 4 weeks; however, they were nearly absent in HFD + CL-fed mice. The serum expression level of inflammation-associated Ccl2 was lower in HFD + CL-fed mice than in HFD-fed mice. Thus, calamondin may ameliorate HFD-induced metabolic disturbances, including the progression of non-alcoholic fatty liver disease. [ABSTRACT FROM AUTHOR]
