To popularize defatted soy ontjom (DSB-ontjom, soy product fermented with Neurospora intermedia) as a new food, I examined the plasma cholesterol-reducing effects of DSB-ontjom and DSB in rats fed cholesterol-free diets and compared the efficiencies of these effects. DSB-ontjom greatly reduced the plasma cholesterol level and increased fecal steroid excretion as compared to DSB. DSB-ontjom was rich in pepsin-resistant protein having a high bile acid binding capacity and was abundant in isoflavone-aglycones, especially daizein. The dietary fiber (DP) of DSB-ontjom stimulated the production of short-chain fatty acids (SCFAs) by intestinal microflora. The effect of DSB-ontjom on plasma cholesterol reduction was attributed to the collaborative effects of pepsin-resistant-protein, isoflavone-aglycones and SCFA-producing DF in DSB-ontjom
