Tea people and friends generally know the appropriate water temperature needed to make tea, and treat them differently according to each tea species to ensure the best brewing quality. But I rarely pay attention to the temperature of the tea, and even think this problem is ridiculous. What else does the tea temperature need to be exquisite, is not it to put up the blowing air, you can drink it when you enter it, which needs such a complex consideration? But if you want to be a "meticulous and attentive" tea person, there are still many exquisite tea drinking temperatures. The optimal drinking temperature of tea is not only related to the taste of tea, the release of beneficial elements, but also your health.
Foreign: Start with a set of data
In September 2011, the famous British journal "British Medicine" published a study report that "drinking tea above 69 °C can increase the risk of esophageal cancer". According to the results of the study, the risk of esophageal cancer in people who drank tea at 70 ° C or higher was 8 times higher than that of normal people; the risk of esophageal cancer in people who drank tea at 65 ° C to 69 ° C was 2 times higher than that of those who drank at a temperature lower than 65 ° C; and the risk of drinking tea brewed for less than 2 minutes was 5 times higher than that of tea brewed for 4 minutes.
The report does not give a specific answer to the optimal temperature at which to drink tea, but only generally speaks, hot tea above 70 ° C cannot be drunk. Therefore, many scholars at home and abroad have given their own research conclusions on the basis of this research report, and the temperature concentration is 62 °C, 60 °C, and 56 °C. In general, scholars have always agreed that the best temperature for drinking tea should be around 60 ° C. So is this answer the most scientific?
Mucous membranes: Temperature, I decide
The key to the optimal temperature for drinking tea is not the temperature itself, but the ability of the esophagus and gastric mucosa to withstand. According to the answer of medical experts, the outermost side of the esophagus is composed of mucous membranes, which is a membrane-like structure composed of epithelial tissue and connective tissue, which can secrete mucus and is the first line of defense of the human immune system. But very delicate, can only tolerate a temperature of 50 ~ 60 ° C, beyond this temperature, the mucous membrane of the esophagus will be burned, and just brewed tea, the temperature of up to 80 ~ 90 ° C.
According to medical theory, once the mucous membrane is burned, in order to repair these damages in time, the epithelial cells of the esophageal mucosa must accelerate their proliferation. If you often eat hot food, the mucosal damage has not been repaired and is burned, and superficial ulcers can be formed. Repeated burn repair, repair of burns, it will cause changes in mucosal quality, further develop into cancerous tumors. Therefore, medical experts give the answer, in order to eliminate esophageal cancer caused by overheated food, eating and drinking water should not be too hot, hot soup, hot tea, hot coffee, hot milk is best to drink when it is cool to about 40 ° C.
Chinese medicine: Tea has a distinction between hot and cold
People who love hot tea generally say: tea can only taste the aroma of tea if it is drunk while it is hot. Especially after the popularity of kung fu tea, drinking tea is becoming more and more hot. Regardless of the stimulation of hot and cold on the mucous membrane of the esophagus, must tea be drunk when it is hot to be the most delicious? This in itself is a very debatable question. A large number of practical experience tells us that when tasting tea, the aroma is the best, and the most suitable tea when it is hot is not supported by practical experience.
The answer given by Chinese medicine to the temperature of drinking tea is - warm. Warm, not hot or cold, soft temperament, most suitable for entrance. In addition, according to the theory of Chinese medicine, the same cup of tea, the health effect of hot and cold drinking is very different. Cold tea into the belly, not only no effect of clearing heat and phlegm, but also has the side effects of cold polyphlegm; hot tea into the belly, the coolness of tea borrows the "fire gas" in the body and rises, making people temporarily refreshed; and drinking warm tea, the effect is the best, the "fire gas" in the body is reduced due to tea nature, and it is excreted from the urine, which is the most natural and healthy.
Conclusion: Make tea for four minutes and drink again
According to the above analysis, it may not be possible to give a standard numerical answer to the temperature of drinking tea, and drinking tea varies from person to person. But one thing should be very clear - tea is best drunk warmly, preferably 4 minutes after brewing. While enjoying the taste of tea, you should also consider the endurance of the mucous membrane of the esophagus. Hot tea is not advisable, of course, cold tea is not advisable, warm tea is the most appropriate.
