This study was performed to investigate the effects of Cheonggukjang (traditional soybean food, CK) and Cheonggukjang added with Phellinus linteus myceria (CKP) on the lipid metabolism, growth, food intake, and food efficiency ratio(FER) in adult female rats. Sprague-Dawley rats were fed a high fat diet (control diet: 0.1% cholesterol, 10% Lard) for 4 weeks. The rats were randomly assigned to each treatment group: control, and two kinds of CK and CKP (powders of CK and CKP as dietary protein sources). After 4 weeks of experimental diet consumption, the body weights and the uterine fat pad weights of the CK and CKP diet groups were more significantly decreased than those of the control diet group. The hepatic cholesterol, triglyceride and total lipid levels were significantly lower in both the CK and CKP diet fed groups than those in the control group. The concentrations in serum triglyceride and LDL-cholesterol were significantly decreased in the CK and CKP diet groups compared to those in the control group. Fecal total lipid, moisture and wet weight excretion in the CK and CKP diet groups were more increased than those in the control group. These results showed that feeding of cheonggukjang and cheonggukjang added with Phellinus linteus myceria both the triglyceride and LDL-cholesterol in serum, as well as the triglyceride and cholesterol in the livers of the rats.
