Western-style diets increase the risk for cardiovascular diseases. It is suggested that the risk could be prevented by lowering cholesterol concentrations in blood. In the present study, hypocholesterolemic effects of the probiotics isolated from kimchi (Lactobacillus curvatus KFP419, Leuconostoc paramesenteroides KJP421, and Leuconostoc mesenteroide subsp. mesenteroides KDK411) were investigated in hypercholesterolemia-induced rats. There was no difference in growth performance between the rats fed high cholesterol diet (HCD) and normal diet (ND). However, blood total cholesterol, low-density lipoprotein cholesterol, and hepatic cholesterol were elevated by the HCD compared to ND, and those concentrations were decreased by dietary supplementation of KFP419 and KDK411. It was concomitant with an increase in fecal excretion of neutral sterols (cholesterol, coprostanol, and coprostanone) in the rats fed HCD compared to ND and was even greater with KDK411 supplementation. These findings indicate that probiotics L. curvatus KFP419 and L. mesenteroide subsp. mesenteroides KDK411 isolated from kimchi ameliorate hypercholesterolemia in rats by assimilating and excreting cholesterol in feces.
