Eating too fast will make the food unable to be chewed fully. The food with coarse particles and high temperature will easily damage the fragile esophageal mucosa epithelium, make it burst and cause acute inflammation. A woman in Wuhan "wolfed down" her meal for a long time, with an average meal time of only about 5 minutes. As a result, her esophagus has lost its normal peristalsis function and can't promote food swallowing. Zhang Chuan, director of the Department of Gastroenterology, Beijing Chaoyang Hospital, told the reporter that eating too fast will make the food unable to be chewed fully. The food with coarse particles and high temperature will easily damage the fragile esophageal mucosa epithelium, make it burst and cause acute inflammation. If inflammation forms a scar on the epithelium of the esophagus, it will obviously affect its normal motor function, so it is not surprising that it is difficult to swallow. If you think that dysphagia and esophagitis are just "minor problems", then eating fast and food temperature is easy to induce esophageal cancer is a big problem. Linzhou, Henan Province is a high incidence area of esophageal cancer, which is related to the fast eating speed and overheating of food in Linzhou. Of course, eating slowly is not as slow as possible, because digestive enzymes that digest food have a secretion peak. Generally, within ten minutes, the concentration of digestive enzymes in the secretion peak reaches the best food digestion point, which is conducive to the decomposition and absorption of nutrients. If you eat oily food and are stimulated by fat, bile will be discharged from the gallbladder to the intestine at once to concentrate on digesting fat. However, if the meal time is too long, bile will enter the intestine in batches. If the amount of bile is not enough, it may not fully digest fat, which may easily accumulate fat and lead to obesity. Therefore, eating too fast or too slowly may lead to obesity. Director Zhang suggested that it is best to chew slowly for about 20 to 30 minutes for each meal, which refers to the actual time of chewing and swallowing, and does not include the time of pushing cups and chatting during meals.
