When rats were fed a hypercholesterolemic diet supplemented with egg phospholipids,s the cholesterol concentrations in serum and liver were decreased, and cholesterol excretion into feces was increased, in comparison with rats fed a diet without egg phospholipids. Addition of fish oil to the diet supplemented with egg phospholipids lowered the serum cholesterol concentration further, but decreased the ratio of cholesterol excretion into feces, compared with the single supplement of egg phospholipids. The hypercholesterolemic diet supplemented with krill phospholipids containing fatty acids similar to those in fish oil also decreased the ratio of cholesterol excretion into feces, compared with the hypercholesterolemic diet supplemented with egg phospholipids. It was shown that the decrease in serum cholesterol caused by the diet containing fish oil with egg phospholipids might have been due to the cooperative effects of the two supplements, and it was considered that fish oil might participate in these mechanisms except for the suppression of fecal cholesterol excretion
