Often eat hot rice, and eat very quickly is no good, one, too hot easy to scald the mouth or esophagus, reduce the sense of taste, two, eat too fast easy to cause indigestion, because the first gateway to food digestion is the oral saliva, food in the mouth chewing for a long time will stimulate the distribution of saliva in the oral cavity to help the further digestion of the food, so eating must not be too hot too fast.
