Effect of peptide relating to food intake behavior on swallowing in the developmental process

感觉饱腹感的因素之一是血糖的增加。血液中胰岛素水平的升高引起血糖的升高，调节进食行为。另一方面，甜味刺激在血糖水平增加之前诱导瞬时胰岛素分泌（胰岛素释放的头部相;CPIR）。在测试的味觉刺激物中，酸溶液促进吞咽的开始，因为与其他味觉刺激物相比，酸刺激期间的吞咽间隔显著更短。吞咽时味觉强度的感觉量表在酸性溶液中较高。结果表明，味觉刺激的效果在促味剂中各不相同，酸刺激可能有助于吞咽。

One of the factors to feel satiety is an increase in blood glucose. Increase in blood insulin level caused by an increase in blood glucose regulate feeding behavior. On the other hand, sweet taste stimulation induce transient insulin secretion before increase in blood glucose level(Cephalic Phase of Insulin Release;CPIR).In the present study, I investigated the effect of taste stimulation in the pharynx. Out of taste stimulants tested, acid solution facilitated initiation of swallow, in that the swallowing interval was significantly shorter during acid stimulation as compared to other taste ones. Sensory scale of taste intensity during swallowing was higher in acid solution. The results suggest that the effect of taste stimulation varies among tastants, and that acid stimulation may facilitate swallowing.
