Role of caloric content on gastric emptying in humans.

摘要: 1. This study examined the effects of caloric content (caloric density and nature calories) on rate gastric emptying using double-sampling aspiration technique. Four test meals 600 ml (glucose, 0.1 kcal ml-1; pea whey peptide hydrolysates, both 0.2 milk protein, 0.7 ml-1) were tested in six healthy subjects random order four separate occasions. 2. The glucose solution was emptied fastest with a half-time 9.4 +/- 1.2 min (P < 0.05) protein slowest 26.4 10.0 0.05); hydrolysate solutions had half-times 16.3 5.4 17.2 6.1 min, respectively. rates for derived from different sources not different. 3. Despite lower solution, delivery to duodenum during early phase process higher than that other three (46.3 6, 63.5 22, 62.5 19 113.8 25 cal min-1 kg-1 glucose, hydrolysate, meals, respectively; P 0.05). linearly related (r = 0.96, as well at which calories delivered 0.99, 0.001). 4. demonstrates is function ingested meal linear relationship exists between these variables. Furthermore, seems play minor role determining humans.
