Eating foods at higher temperatures can cause varying degrees of damage to the esophageal mucosa and can increase the incidence of esophageal cancer if foods at higher temperatures are eaten for long periods of time.
It takes about 9 seconds to swallow food from the esophagus into the stomach, and swallowing food with a temperature of more than 65°C will cause the esophagus to undergo a 9-second scalding process, and if the food is too hot, it will burn the esophageal mucosa and cause mucosal necrosis, which can lead to cancer of the esophagus over time. The wall of the esophagus is an elastic tissue consisting of the epithelial, submucosal and muscular layers. The innermost layer of the esophageal lumen is the mucosal epithelium, which is thin and soft and comes into direct contact with food, making it highly susceptible to irritation from overly hot food, causing mucosal breakage, ulceration, and bleeding.
Therefore, it is important to avoid eating foods that are too hot when you eat. It is also important to avoid eating coarser foods that can also cause mechanical damage to the esophageal mucosa. Each meal is best to chew and swallow slowly, preferably within 20-30 minutes of eating the meal. Do not eat more spicy and stimulating foods that can also harm the esophageal mucosa. You can eat more fresh fruits and vegetables.
