Output of bilirubin and pancreatic enzymes in response to different liquid test meals in man.

The output of bilirubin and pancreatic enzymes was determined after ingestion of three different liquid test meals in man. Doubling the amount of protein in a composite meal was followed by a delivery of more protein per time unit to the intestine and by a higher output of bilirubin and enzymes than was recorded after a similar meal containing less protein. The ingestion of a 15% glucose solution awoke a considerable output of bilirubin and enzymes during the first hour, thereafter it was low and decreasing. The differences in enzyme and bilirubin output corresponded to differences in quality and quantity of the emptied food components.
