In recent days the colder air has come. Many people prefer to eat hot pot, sweet potatoes and so on to resist the cold. Experts suggest that long-term overheating eating habits may cause oral and digestive tract damage, raising the risk of oral and esophageal cancer.
"Oral mucosa burns are caused by acute food, oral mucosa is the first line of defense in our mouth, although it is insensitive to high temperature, food and drink at 40 or 50 degrees cannot feel hot. But the oral mucosa is not resistant to scalding, and it is easy to burn when it comes to high temperature. Zhou Jian, deputy chief physician of the emergency comprehensive diagnosis and treatment center of Beijing Stomatology Hospital affiliated to Capital Medical University, said the tolerance temperature of oral mucosa is about 50-60°C, and when eating feels hot, the food temperature can generally reach 70°C, which can easily lead to scalding of oral mucosa.
In addition, the overheated diet will pass through the esophagus, the surface of the esophagus epithelial cells are more delicate than the mouth, the mouth cannot tolerate the high temperature food, more damage to the esophagus. Li Yong, deputy chief physician of thoracic surgery at the National Cancer Center and oncology hospital of the Chinese Academy of Medical Sciences, said foods above 65°C could damage the digestive tract mucosa. "The temperature in our digestive tract is about 37°C, and the highest tolerance in the esophagus is 50-60°C. And the hot pot's soup temperature can reach 120°C, just brewed hot tea temperature of about 90°C, are far above the esophagus tolerance temperature.
Hot drinks above 65°C are likely to increase the risk of esophageal cancer, according to the World Health Organization's International Agency for Cancer Research (IARC). Li Yong said that too hot food in the esophagus, will burn mucosal epithelium, resulting in breakage, ulceration, bleeding. If you often eat hot food, these parts will be repeatedly injured, repeatedly by bad stimulation, long-term disease or even cancer.
Long-term consumption of a diet above 65°C can damage cells in the oral and esophageal mucosa and may increase the risk of developing oral and esophageal cancer, experts said. Do not eat "hot food" in winter. The recommended safe eating temperature is 10-40°C. (Reporter Wang Bingyang)
Even if you eat less sweet food or no sweet food, but eat some staple food for a long time, such as rice, noodles, steamed bread and other starchy foods, or even eat too much sugary high-grade fruit, may occur abnormally high blood sugar, or even induce diabetes.
In recent years, in some villages in northern Guangdong, all kinds of \"soil squeeze \"\"now squeezed\" peanut oil is sought after by city people and tourists. But are some of the \"pure groundnut oil\" produced by small workshops really \"pristine \"?
