The weather is getting colder and colder, although the temperature has risen in recent days, but the main tone of winter is set, we should pay attention to “avoid the cold on the temperature” “no drain on the skin” in life. We can’t eat cold things, but we should also be careful not to eat too hot, to avoid “eating while hot” damage to the body. The winter cold, diet hot diet can help us to protect the cold, promote the operation of blood and Qi, and food in the fresh pot when the taste is most delicious, can meet our appetite. However, the harmful effects of overheated food on the body should not be underestimated. The high temperature can cause burns on the esophageal wall and stomach wall, damaging the mucosa and causing ulcers. The mucosa of the digestive tract is very capable of repair, so once or twice an overheated diet will not generally have a significant impact on health. But if the diet is often too hot, the esophageal mucosa will not be able to hold up even if the repair is fast, and ulcers will form and expand, and will not heal for a long time. But the scary thing is not the ulcer, but the subsequent pathological development. The mucous membrane is constantly being destroyed, repaired, destroyed, repaired, and in the process of cell regeneration, the cells themselves will change, genes will mutate, and the chance of malignant tumors will be very high. So we should boil the food in our life, but pay attention to the right amount of hot and cold when consuming. Generally, the digestion process of food is carried out at a temperature similar to the body temperature, so the temperature should be moderate when eating, 40~50℃ is the best. Neither too cold to cause abdominal pain and diarrhea, nor too hot to damage the delicate mucosa. In short, everything is in moderation, grasp a degree, even without special attention to health, we can also maintain health, less disease.
