Effect of partial hydrolyzate of casein and soybean protein on serum lipoproteins and fecal neutral steroids in cholesterol-fed rats was studied. In rats fed partial hydrolyzate of casein, the levels of plasma and liver cholesterol, liver triglyceride and the ratio of serum β/α lipoprotein had a tendency to decrease compared with those in rats fed intact protein. On the other hand, no difference was observed between soybean protein and partial hydrolyzate of soybean protein diet groups. The excretion of neutral steroids to feces and the amount of fecal coprostanol were increased in rats fed soybean protein and partial hydrolyzate of soybean protein.
