Steaming lamb
The dumplings that just came out of the pot were chaotic
Fried food that just picks up the pan
……
"Piping hot" cuisine
It is the standard for this cold winter
I don't know,
Relevant studies at home and abroad confirm that:
People who consume foods that are too hot for a long time are at risk of cancer
Will be higher.
Don't call on family and friends again
"Eat while it's hot" or "Drink it while it's hot"!
01
What temperature counts as a burn?
Usually, the temperature range of our mouth and esophagus is between 36.5 and 37.2 ° C, and the food temperature that the mouth and esophagus can withstand is between 10 and 40 ° C, and the highest temperature that can be tolerated is between 50 and 60 ° C. 65°C belongs to a most conservative dividing line. Therefore, in general, food above 65 ° C can be considered hot.
After eating hot food for a long time, causing mucosal damage, the harm caused to the body is not a joke.
02
Eat hot food or drinks for a long time
It is easy to produce the following five major hazards
★ Hazard 1 Damages the tooth and causes toothache
Hot food or drinks can damage tooth tissue, causing swollen gums, allergic toothache, etc.
★ Hazard 2 Damages the taste buds, causing the taste to become heavier and heavier
Hot food or drinks can destroy the taste buds of the tongue, causing the taste buds to slow down and making people taste heavier and heavier.
★ Hazard 3 Damages the oral mucosa and causes oral cancer
The surface of the human mouth and esophagus is covered with a soft mucous membrane, and under normal circumstances, the temperature of the oral esophagus is maintained at the level of body temperature. The mucous membrane of the human mouth is extremely thin, but it has a protective function against mechanical injuries and microbial and viral invasions.
The oral mucosa also has sensory function, and responds in time to pain caused by the outside world, and can feel the taste. The oral mucosa is not heat-resistant and is easily burned. The temperature of eating hot food may reach 60 ° C ~ 70 ° C and above, which can burn the mouth, resulting in blistering, peeling, ulcers, pain and other oral problems, long-term recurrence, difficult to heal, inducing changes in mucosal quality and even causing oral cancer.
★ Hazard 4 Damages the mucosa of the esophagus and causes esophageal cancer
For the average person, when the mouth feels a little hot, the temperature of the food is actually at least 70 ° C, far more than the temperature that the esophagus can withstand.
Long-term persistent stimulation is likely to cause lesions in the mucous membranes, from superficial inflammation and ulcers to malignant hyperplasia, increasing the risk of esophageal cancer. The Lancet Oncology magazine published a report by the World Health Organization's (WHO) International Agency for Research on Cancer in 2016, which explicitly warned that drinking hot drinks above 65°C may increase the risk of esophageal cancer.
★ Hazard 5 Damages the gastric mucosa and causes stomach cancer
Hot food or drinks can cause great damage to the stomach. The heat-resistant temperature of the gastric mucosa is generally at 40 ° C, so it is often not hot in the mouth, but it will "burn" the stomach, which will cause damage to the gastric mucosa, bleeding and other conditions.
At the same time, the stomach continues to secrete digestive juices, after the gastric mucosa is damaged, it is more susceptible to corrosion of digestive juices, and the gastric mucosa suffers repeated damage for a long time, which is easy to cause gastric ulcers, gastritis, stomach pain, and even cause stomach cancer.

So what should we do?
The correct posture is as follows:
(1) After the meal comes out of the pot, it should be cooled for a while before eating
。 To be on the safe side, we can take all the food out of the pot for a while before bringing it to the table. When eating, first put the food on the lips to feel the temperature, if it does not feel hot, then eat it. Remember, don't eat food that just came out of the pot.
(2) When eating hot pot, remember that "you can't eat hot tofu in a hurry." Instead of eating food that has just been fished out of the pan, be sure to leave it in a dipping bowl for a while, or prepare an empty plate and fish out the food for a while before eating, which will be safer.
(3) The secret of drinking warm water every moment: the constant temperature kettle. For people who do not like to drink cold water, prepare a constant temperature kettle, the water temperature is controlled between 40 ~ 45 ° C, and the water with the right temperature at home can drink warm water!
(4) Change the habit of drinking hot drinks. Some people like to drink hot tea and hot coffee (hot mouth like that), it's really not a good habit, and it needs to be changed. If you insist that this temperature is fine and completely acceptable, then you really have to seriously consider it, is it because your oral and esophageal stomach has been injured and used to it?!
