Once the weather is cold, the hot pot, the stream of colorful salami are on people’s tables one after another, and its popularity can be seen from the long queues of people at the entrance of the major hot pot restaurant. After a year of bland taste buds in the winter finally have a reason to stimulate in the numb, hot, spicy, hot. However, overheating of food, eating too fast, eating pickled food and drinking strong alcohol are likely to induce esophageal cancer. Zhang Huizhong, Associate Professor of Cardiothoracic Surgery at Zhongshan Second Hospital, said that esophageal cancer is related to diet, smoking, alcoholism, chronic inflammation of the esophagus and heredity. China is a high incidence area of esophageal cancer, with patients accounting for about 1/2 of the world, while Chaoshan and Hakka areas in Guangdong Province are also high incidence areas of esophageal cancer, which is related to local dietary habits. Esophagus is the channel from mouth to stomach, and the innermost part of this channel is a layer of mucosal epithelium, which is both thin and soft, and is in direct contact with food, so it is most susceptible to various kinds of food stimulation. If eating too rough or too hot food, it will damage or scald the mucosal epithelium of the esophagus and cause it to be broken, ulcerated, bleeding and other problems. Although the mucosal cells have the function of self-repair, long-term damage is prone to cancer. And Guangdong Chaoshan people are used to drinking instant Kung Fu tea and hot raw congee, which are thermal stimuli to the esophagus and may form local chronic inflammation in the esophagus and cause cancer. In addition, pickled foods are commonly eaten by Hakka people, and nitrosamines can often be found in pickled meats and fish, sauerkraut, and this chemical is a strong carcinogen, which can cause esophageal cancer and many other tumors. In addition, eating too fast can also damage the esophagus, so chew and swallow slowly when eating to avoid chronic irritation of the esophageal mucosa.
