Fig. 6.
Cumulative lymphatic GIP (A) and GLP-1 (B) output following either a duodenal whey protein, protein hydrolysate, or saline bolus (0.275, 1.1, 4.4 kcal for each nutrient). Cumulative secretion was calculated by summing together the hourly GIP or GLP-1 output values during the 3-h collection period. Values are means + SE. *P < 0.05: protein vs. protein hydrolysate at that dose.
