Abstract

This study was performed to investigate the ameliorating effects of steamed soybeans (SS) and fermented SS (FSS) on lipid metabolism in high-fat diet-induced obese mice. ICR mice were divided into four groups and given the following different diets: normal diet (ND), high-fat diet (HFD), HFD with 1% SS (HFD + SS), and HFD with 1% FSS (HFD + FSS). After 14 weeks, the body weight gain was higher in the HFD group compared with the ND group but lower in the HFD + FSS group compared with the HFD group. Plasma levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein-cholesterol, aspartate aminotransferase (AST), and alanine aminotransferase (ALT) were significantly higher in the HFD group compared to the ND group, but lower in the HFD + SS and HFD + FSS groups compared with the HFD group. In addition, leptin concentration in plasma was lower in the groups fed HFD + SS and HFD + FSS compared with the HFD group. The accumulation of hepatic TG and TC was significantly inhibited in the HFD + SS and HFD + FSS groups. Furthermore, SS and FSS attenuated lipid peroxidation and nitric oxide formation in the liver induced by the high-fat diet. These results suggest that soybeans, especially FSS, may be useful in preventing obesity-induced abnormalities in lipid metabolism.
