A woman, due to her long-term habit of wolfing down meals in about 5 minutes on average, has lost the normal peristaltic function of her esophagus, making it unable to push food down for swallowing. Experts told reporters that eating too quickly prevents food from being chewed sufficiently. Coarse, high-temperature food can easily damage the already fragile esophageal mucosal epithelium, causing it to break down and trigger acute inflammation.
If inflammation forms scars on the esophageal epithelium, it will obviously affect its normal motor function, so it is not surprising that difficulty in swallowing occurs.
If you think that dysphagia and esophagitis are just "minor ailments," then the fact that eating too quickly and consuming food at high temperatures can easily induce esophageal cancer is a major problem.
Of course, chewing slowly and deliberately is not a case of "the slower, the better," because digestive enzymes have a peak secretion period, generally within a dozen minutes. During this peak, the concentration of digestive enzymes reaches the optimal point for digesting food, which is conducive to the breakdown and absorption of nutrients. If you eat greasy food, stimulated by fat, bile will be discharged from the gallbladder into the intestine all at once to concentrate on digesting fat.
However, if the meal is too long, bile will enter the intestine in "installments." If the amount of bile is insufficient, it may not fully digest the fat, which can easily lead to fat accumulation and obesity. Therefore, both eating too fast and too slowly can lead to obesity. Experts suggest that the ideal time for a slow, deliberate meal should be around twenty to thirty minutes. This refers to the actual time spent chewing and swallowing, and does not include the time spent drinking and chatting during the meal.
