Hot food trap Many people like to eat hot food, whether it is hot pot or freshly brewed hot tea, they like to taste it at the first time. It seems that "eating while it is hot" has always been a tradition in China. Whenever a new dish is just served, the host will never forget to say hello: eat it while it is hot. It seems that only in this way can we show our hospitality. But should eating really be hot? Eat it while it's hot, okay?

Under normal circumstances, the temperature of human mouth, esophagus and stomach is 36-37℃, and the temperature of what we call "hot food" is generally 60-70℃. It is conceivable that the most direct impact of eating too hot food is the damage of oral mucosa, which causes congestion and ulcer of oral mucosa and destroys its function of protecting oral cavity. In addition, high-temperature burns are harmful to gums and teeth, which can lead to gum ulceration and allergic toothache. If you eat hot food for a long time, the damaged mucosa can be repaired and then burned, which will form a superficial ulcer. It can cause oral mucosal inflammation, esophagitis, chronic gastritis, and even induce oral cancer, esophageal cancer and gastric cancer.

Too hot food can cause esophageal mucosal damage, leaving scars and inflammation. Epithelial cells need to be renewed after scald. The more changes are updated, the more mutations may occur, which may cause malignant lesions in the long run. In addition, when we eat hot food, we usually swallow it faster, and the food is often swallowed before it is fully chewed. In this way, you can't drink digestive juices such as saliva, which will increase the burden on your stomach. In the long run, it is not conducive to the digestion and absorption of food. By analyzing the epidemiological research results of risk factors of esophageal and gastric cancer in China in recent 10 years, it is found that. The main dietary risk factors of esophageal cancer and gastric cancer in China are overeating, irregular diet, like frying, like spicy food, high-salt diet and so on. If these habits can be changed, the incidence of esophageal cancer and gastric cancer will be reduced by 50%.

Eating less foods with high fat, high sugar, high protein and low cellulose is an important factor for the high incidence of digestive tract tumors. Avoiding these unreasonable diets plays an important role in preventing cancer and cardiovascular diseases. Keep the food fresh. Deteriorated vegetables contain high nitrate and nitrite; Moldy rice, corn and peanuts will produce aflatoxin; Deteriorated ginger contains safrole; Rotting oil and its products are carcinogens. Chewing slowly when eating can promote a lot of saliva secretion. Lysozyme, amylase and secretory immunoglobulin antibodies in saliva have bactericidal, digestive and antitoxic effects. Pay attention to a balanced diet, because all kinds of nutrients are important to human health. Lack of nutrition will reduce immunity and create conditions for cancer. Overnutrition or imbalance is also a potential cancer risk.
