摘要: Diets rich in proteins promote long-term body weight loss by increasing satiation with a greater effect than carbohydrates and fats. l-glutamate that imparts umami or savory taste is thought to be signal for protein consumption may the satiating of proteins. The ingestion results release anorexigenic gut neuropeptides such as cholecystokinin, glucagon peptide 1, YY transmit satiety signals brain steam via vagal afferent pathways. Gut come from enteroendocrine cells disseminated throughout alimentary canal. They express chemosensing receptors apical membrane can detect presence peptone single amino acids luminal content. High-protein diets convey stronger AA-satiating brainstem arcuate nucleus. also reduce hedonic responses reward system. This chapter reviews gustatory perception mouth their distribution AA sensors gastrointestinal tract including short overview on contribution integration protein-satiety brain.
