We acclimated house sparrows (Passer domesticus; 26 g) to high-starch (HS), high-protein (HP), and high-lipid (HL) diets and tested the predictions that uptake of D-glucose and amino acids will be increased with increased levels of dietary carbohydrate and protein, respectively. HS birds had lower mediated D-glucose uptake rate than HP birds. Total uptake of L-leucine at low concentration (0.01 mM), but not of L-proline at 50mM, was increased by dietary protein. Measures of D-glucose maximal mediated uptake (1.2 +/- 0.2 nmol.min-1.mg-1) and intestinal mass (1 g) indicated that the intestine's mediated uptake capacity was only approximately 10% of the D-glucose absorbed at the whole animal level. This implied that nonmediated glucose absorption predominated. We applied a pharmacokinetic technique to measure in vivo absorption of L-glucose, the stereoisomer that does not interact with the Na(+)-glucose cotransporter. At least 75% of L-glucose that was ingested was apparently absorbed. This adds to the increasing evidence that substantial passive glucose absorption occurs in birds and may explain why mediated D-glucose uptake does not increase on high-carbohydrate diets.
