Don’t drink hot tea above 70℃!

Tea, cocoa and coffee are the three major non-alcoholic beverages in the world. Liu is a typical tea lover: he started drinking tea when he was young, and now he is 68 years old and still drinks some tea every day.

Recently, Liu always felt that there was something stuck in his throat, and he couldn't spit it out or swallow it. He thought it was pharyngitis, but he bought medicine and it didn't get better. Later, even drinking water became difficult. He went to the hospital for a checkup accompanied by his wife, and was diagnosed with advanced esophageal cancer!

After the consultation, the doctor believed that Liu's esophageal cancer was related to long-term drinking of hot tea - long-term drinking of hot tea caused damage to the esophageal mucosa, which made him the target of esophageal cancer.

So, do people who drink tea regularly increase their risk of cancer? In daily life, which is better for our health, tea or water?

In fact, tea polyphenols contained in tea have a strong antioxidant effect and can effectively remove excess free radicals that are harmful to the human body. Tea polyphenols and their oxidation products can absorb radioactive substances and help prevent and treat radiation damage. The caffeine in tea has the effect of refreshing the mind, diuresis and relieving fatigue.

It is generally believed that drinking tea in moderation is good for health.

Tea itself is not carcinogenic. It is these three types of tea that may cause cancer!

01. Moldy tea

Once tea leaves become moldy, the brewed tea will not only lack tea fragrance, but may also cause symptoms such as diarrhea and dizziness. Do not drink the tea leaves once you find they are moldy.

02. Burnt Tea

If the tea is over-baked, it may produce a burnt smell, which will destroy certain components of the tea and even produce certain carcinogens. Therefore, try to stay away from burnt tea.

03. Overscalding tea

Drinking too hot tea can cause burns to the esophageal mucosa. Repeated irritation may increase the risk of cancers such as esophageal cancer and gastric cancer.

Which is healthier, drinking tea or drinking boiled water for a long time?

Tea contains caffeine, tea polyphenols, catechins and other nutrients, and is regarded as a health drink by many people.

Drinking tea properly can regulate blood lipid metabolism, prevent cardiovascular and cerebrovascular diseases, promote the growth of beneficial bacteria and maintain intestinal health.

Drinking tea has so many benefits, does that mean that drinking more tea is more beneficial to health than drinking water? In fact, whether drinking tea or drinking water, you have to master a certain degree, and you can't absolutely say which is better or worse!

Being overly keen on drinking tea and drinking tea as water may cause the following hazards!

Damage to the kidneys: Tea can be a diuretic. Drinking too much tea can lead to frequent urination and may also cause excessive caffeine intake, which increases the burden on the kidneys and damages them.

Insomnia and headache: Tea contains alkaloids. Drinking too much tea can cause over-excitement of the central nervous system, leading to arrhythmia, insomnia, headache, and accelerated heartbeat.

Urinary tract stones: Tea contains high oxalic acid, and drinking too much may induce urinary tract stones.
Gastrointestinal discomfort: Tea polyphenols in tea can accelerate gastrointestinal motility, stimulate the gastric mucosa, lead to excessive secretion of gastric acid, and cause stomach discomfort.
Moreover, people with urinary stones, insomniacs, and patients with gastritis and peptic ulcers are advised not to drink tea or drink less tea!
Relatively speaking, boiled water is a healthy drink that everyone can drink. Drinking water can ensure adequate water intake in the body and maintain the health of blood vessels, skin and intestines. The "Dietary Guidelines for Chinese Residents 2022" recommends that adult women with light physical activities should drink 1,500 ml of water per day, and men should drink 1,700 ml.

Temperature between 56℃-60℃ is more beneficial to health

Studies have shown that people who drink tea at 70℃ or higher have an 8-fold higher risk of esophageal cancer than normal people; people who drink tea at 65-69℃ have a 2-fold higher risk of esophageal cancer than those who drink tea at a temperature below 65℃. When drinking tea, the temperature of the tea water should be between 56℃ and 60℃, which is more beneficial to health. The key to the best temperature for drinking tea is not the temperature itself, but the tolerance of the esophagus and gastric mucosa. According to medical experts, the outermost part of the esophagus is composed of mucosa, which is a membranous structure composed of epithelial tissue and connective tissue. It can secrete mucus and is the first line of defense of the human immune system. However, it is very delicate and can only withstand temperatures of 50-60℃. If the temperature exceeds this, the mucosa of the esophagus will be scalded, and the temperature of the freshly brewed tea is as high as 80-90℃. Tea itself is a drink that is good for the body. I hope all tea lovers will take this as a warning. Hot tea is not only harmful to the mouth, but also harmful to the body. You might as well calm down and wait for a while, so that our health can be guaranteed.
