“The people take food as their heaven”. Chinese people love to eat and are hospitable. It seems that not saying “eat and drink while hot” at the dinner table is not a warm hospitality.
However, a growing body of research shows that by advising people to eat while it’s hot, you may be persuading people to get cancer!

Real hammer! Eating it while it’s hot does cause cancer!
As early as June 2016, a research report published by the International Agency for Research on Cancer (IARC) under the World Health Organization in the journal The Lancet Oncology showed that Drinking hot drinks above 65℃ will increase the risk of esophageal cancer[1].

And, in the officially published carcinogen assessment report, very hot (above 65°C) beverages were listed as probable (Class IIA) carcinogens.
It’s not just hot drinks, but fiery hot foods such as hot pot, which are popular among Chinese people, can be equally harmful. (Seeing this, Uncle Dian’s heart is: You can not drink hot water, but you can’t live without hot pot…)

Recently, a very large population study published in March 2019 in the International Journal of Cancer, Prospective of tea beverage temperature and risk for esophageal squamous cell carcinoma Sex Research”, once again confirmed this theory.
Prospective study confirms high temperature hot tea causes cancer Source: www.intjcancer.org
The study, which followed more than 50,000 people aged 40 to 75 for 10 years, found that hot tea above 60°C, will Increased risk of esophageal cancer.
Studies have shown that tea temperature ≥ 60°C, preference for hot tea, and a short interval between brewing and drinking are all associated with the risk of esophageal cancer [2].
Further analysis showed that compared with those who drank less than 700 ml per day and the tea temperature was <60 ℃, those who drank ≥700 ml per day and the tea temperature ≥60 ℃ increased the risk of esophageal cancer by about 90%. Researchers believe that the temperature of the hot tea may damage the esophagus, cause inflammation, damage DNA, and stimulate the production of carcinogens [2].
So, you may want to ask, what is the concept of drinking tea at 60°C or eating food at 60°C? For normal people, it is a bit hot and hard to swallow.
But for many people around Uncle Dian who are used to “eat and drink while it’s hot”, this temperature is not enough.

China accounts for more than half of the world’s esophageal cancer population
According to the real-time data of the World Health Organization (WHO), the prevalence and mortality of esophageal cancer in my country ranks fifth in the world; due to the huge population base, the number of esophageal cancer cases in my country The number of deaths and illnesses accounts for about 55% of the global total [3].
Specifically, in 2018, the number of new cases of esophageal cancer in China is expected to be 307,000, ranking sixth in incidence; the number of deaths is expected to be 283,000 people, in fourth place[3].
In terms of age of onset, 60-75 years old is the age group with high incidence of esophageal cancer, accounting for more than 50% of all esophageal cancers[4]; followed by
strong>45-60 years old, esophageal cancer is relatively rare under the age of 30.
In terms of gender, males had far more cases than females, 214,000 and 93,000 respectively, and males had more deaths (198,000) than females ( 85,000) [3].
Why does eating while hot increase the risk of esophageal cancer?
Eat while hot is closely related to the occurrence of esophageal cancer.
The surface of the esophagus, covered with delicate mucous membranes, food temperature has a big impact on it. Eating hot food or drinking hot tea for a long time will damage the esophageal mucosa. Repeated burns can form superficial mucosal ulcers, leading to chronic oral mucositis, esophagitis, atrophic gastritis, etc. In the long run, it will induce changes in the mucous membranes and lead to carcinogenesis.
For example, in Chaoshan, Guangdong, where the incidence of esophageal cancer is high in my country, locals love to eat hot food, such as hot kung fu tea and raw porridge. These factors cause persistent damage to the esophageal mucosa, which, over time, eventually evolves into cancer.
In addition, in addition to eating hot food, loves rough food, smoking, drinking, Nitrates or excessive nitrite intake can increase the risk of esophageal cancer.
What are the symptoms of esophageal cancer?
Esophageal cancer may have no symptoms in its early stages.
This is because the esophagus is a “less sensitive organ” compared to other organs. After your esophagus is scalded, you often don’t know it.
For example, if a lot of people burn their mouths with food while eating, they will quickly swallow it so that they don’t feel hot. This is because the esophagus is less sensitive to temperature than the mouth, so even if it gets scalded, it doesn’t feel much.
When many people find that they have difficulty swallowing, they may already be in the middle and late stages of esophageal cancer…
Symptoms of advanced esophageal cancer include: difficulty or pain in swallowing, weight loss, retrosternal pain, cough, hoarseness, indigestion, and heartburn.

Eat, drink and drink, what temperature is a “healthy temperature”?
What is a healthy temperature for eating and drinking?
Generally speaking, it is best to control the temperature of food and drink below 60 ℃; if it is above 60 ℃ for a long time, it may cause burns.
When we usually eat, lips just feel warm, which is actually the most appropriate.
Uncle Dian is here to tell you 3 tips for a healthy temperature diet:
1. Control the temperature of food: Don’t be too anxious to eat, put it aside, let it cool down, and sip it with your mouth until you feel it is not hot.
2.Spit out hot food when you eat it: Sometimes after eating a mouthful of hot food, many people tend to swallow it subconsciously, so that the mouth will not be scalded. , In fact, when this happens, you must spit it out. If you swallow it, it means that you will burn the esophagus once.
3.Cut up the food and eat it again: As the saying goes, “you can’t eat hot tofu in a hurry”, for tofu, eggs, fish tofu and other hot center Food, it is best to use chopsticks to open and crush the food before eating.
