In this study, the investigators aimed at evaluating the role of sweet taste receptors in the
gastrointestinal tract (GIT). Intragastric administration of glucose, fructose or
acesulfame-K were compared with placebo administration for their effects on gastrointestinal
motility, gut hormone release (motilin, ghrelin, glucagon-like peptide-1 (GLP-1) and insulin)
and hunger feelings.
