The Effect of Duodenal, Ileal or Combined Infusion of Tastants on Food Intake
Rationale: The appearance of tastants in the small intestine can result in the activation of a negative feedback mechanism from different parts of the intestine to the stomach, the small intestine and to the central nervous system. These processes inhibit food processing, appetite sensations and food intake, and furthermore they increase feelings of satiety and satiation. The effects of intraduodenal and/or intraileal infusion of a combination of tastants (sweet (rebaudioside A), bitter (quinine) en umami (monosodium glutamate(MSG))) and placebo on ad libitum food intake, satiation and gastrointestinal symptoms will be investigated.
Objective: To investigate the effect of intraduodenal, intraileal and combined infusion of a combination of tastants versus infusion of placebo on food intake.
Secondary objectives:
- To compare the effect of intraduodenal versus intraileal versus combined intraduodenal and intraileal delivery of a combination of tastants on satiation.
- To assess the effect of intraduodenal and/or intraileal delivery of a combination of tastants on gastrointestinal symptoms/complaints.
