简要总结
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.
