title: Steroid pattern of bile and feces in response to a fruit-enriched diet in hypercholesterolemic hamsters.
abstract: The effect of a fruit (apple)-enriched diet on bile secretion and on fecal steroid excretion was studied in two strains of hamster: normal hamsters with normal cholesterolemia and spontaneous hypercholesterolemic hamsters with high-level hepatic cholesterol esters (FEC hamsters). Quantitative and qualitative alterations in the steroid composition in bile and feces were accompanied by changes in intestinal morphology. The fruit diet displayed a choleretic effect and increased the output of bile acids from liver in FEC hamsters. In addition, bile collected continuously from cannulated apple-fed animals was enriched with conjugates of cholic acid. Moreover, apple consumption lowered the lithogenic index of the bile. In response to the fruit diet, fecal excretion of bile acids and neutral sterols increased, essentially in the form of primary bile acids and sterol esters, respectively.
