Effects of intraduodenal administration of lauric acid and L-tryptophan, alone and combined, on gut hormones, pyloric pressures, and energy intake in healthy men

Autor: Sina S Ullrich, Christine Feinle-Bisset, Robert E. Steinert, Christina McVeay, Michael Horowitz, Penelope C E Fitzgerald

Publikováno v: The American Journal of Clinical Nutrition. 109:1335-1343

BACKGROUND The fatty acid, lauric acid ('C12'), and the amino acid, L-tryptophan ('Trp'), modulate gastrointestinal functions including gut hormones and pyloric pressures, which are important for the regulation of energy intake, and both potently sup

Suppression of Energy Intake by Intragastric l-Tryptophan in Lean and Obese Men: Relations with Appetite Perceptions and Circulating Cholecystokinin and Tryptophan

BACKGROUND l-Tryptophan reduces energy intake in healthy men. The underlying mechanisms, including appetite, plasma cholecystokinin (CCK), tryptophan (Trp), and the ratio of Trp to large neutral amino acids (Trp:LNAAs ratio), and whether responses di

Intragastric administration of leucine and isoleucine does not reduce the glycaemic response to, or slow gastric emptying of, a carbohydrate-containing drink in type 2 diabetes

Autor: Sina S Ullrich, Michael Horowitz, Christine Feinle-Bisset, Kylie Lange, Rachel A. Elovaris, Maryam Hajishafiee, Penelope C E Fitzgerald

Publikováno v: Diabetes research and clinical practice. 171

In healthy individuals, intragastric administration of the branched-chain amino acids, leucine and isoleucine, diminishes the glycaemic response to a mixed-nutrient drink, apparently by stimulating insulin and slowing gastric emptying, respectively.

Effects of intragastric tryptophan on acute changes in the plasma tryptophan/large neutral amino acids ratio and relationship with subsequent energy intake in lean and obese men

Autor: Maryam Hajishafiee, Sally D. Poppitt, Robert E. Steinert, Michael Horowitz, Natalie D. Luscombe-Marsh, Sina S Ullrich, Christine Feinle-Bisset

Publikováno v: Foodfunction. 11(8)

Circulating tryptophan/large neutral amino acids (tryptophan/LNAA) ratio, an indicator of brain serotonin levels, may be important in appetite regulation, together with gastrointestinal (gastric emptying, plasma cholecystokinin) mechanisms. We have c

Effects of intraduodenal coadministration of lauric acid and leucine on gut motility, plasma cholecystokinin, and energy intake in healthy men

Autor: Sina S Ullrich, Christina McVeay, Robert E. Steinert, Michael Horowitz, Penelope C E Fitzgerald, Christine Feinle-Bisset

Publikováno v: American journal of physiology. Regulatory, integrative and comparative physiology. 318(4)

The fatty acid, lauric acid (C12), and the amino acid, leucine (Leu) stimulate gut hormones, including CCK, associated with suppression of energy intake. In our recent study, intraduodenal infusion of a combination of C12 and l-tryptophan, at loads t

Intragastric Lysine Lowers the Circulating Glucose and Insulin Responses to a Mixed-Nutrient Drink without Slowing Gastric Emptying in Healthy Adults

Autor: Robert E. Steinert, Christine Feinle-Bisset, Michael Horowitz, Iris Nkamba, Sina S Ullrich, Penelope C E Fitzgerald

Publikováno v: The Journal of Nutrition. 147:1275-1281

Background: Lysine is reported to lower the glycemic response to oral glucose in humans and, albeit at high loads, to slow gastric emptying of glucose and decrease food intake in rats.Objective: We investigated the effects of intragastrically adminis

Intraduodenal Administration of L-Valine Has No Effect on Antropyloroduodenal Pressures, Plasma Cholecystokinin Concentrations or Energy Intake in Healthy, Lean Men

Whey protein is rich in the branched-chain amino acids, L-leucine, L-isoleucine and L-valine. Thus, branched-chain amino acids may, at least in part, mediate the effects of whey to reduce energy intake and/or blood glucose. Notably, 10 g of either L-

Chronic isoleucine supplementation prevents diet-induced weight gain in rodents. Acute-isoleucine administration improves glucose tolerance in rodents and reduces postprandial glucose levels in humans. However, the effect of chronic-isoleucine supple

Tryptophan stimulates plasma cholecystokinin and pyloric pressures, both of which slow gastric emptying. Gastric emptying regulates postprandial blood glucose. Tryptophan has been reported to decrease energy intake. We investigated the effects of int

Publikováno v: American Journal of Physiology-Regulatory, Integrative and Comparative Physiology. 308:R300-R304

Intraduodenal infusion of lipid or protein potently reduces subsequent energy intake. There is evidence that the underlying mechanisms differ significantly between the two nutrients. While intraduodenal lipid stimulates glucagon-like peptide-1 and CC
