【 摘 要 】

Soybeans and fermented soy-derived foodstuffs contain many functional components and demonstrate various beneficial effects. In this report, we demonstrate the anti-fatty liver effect of miso, a traditional fermented product made from soybeans and rice molded in Aspergillus oryzae and forming a common part of the Japanese diet. After acclimation for 2 weeks, male and female C57BL/6J mice were fed with a normal diet (ND), a high-fat diet (HFD), a HFD containing 5% miso (HFD+M), or a HFD containing 5% pre-fermented miso (HFD+PFM) for 20 weeks. Although mice in the HFD group developed typical fatty liver, the consumption of miso or PFM significantly ameliorated the progression of fatty liver in female mice. The liver weight and the average nonalcoholic fatty liver disease activity score (NAS) were significantly reduced in the HFD+M and HFD+PFM groups. In addition, leptin and resistin levels in the serum were decreased in the HFD+M and HFD+PFM groups. The progression of fatty liver was also prevented by the consumption of miso or PFM in male mice, although there were no decreases in NAS. Therefore, miso appears to be a potential food to prevent lifestyle-related diseases such as metabolic syndrome.
