Don't drink too much of these 4 kinds of tea. Don't blame me for not reminding you.

Tea, as a traditional drink of the Chinese people, is not only a culture, but also a way of life. Moreover, the tea polyphenols contained in tea have powerful antioxidant and free radical scavenging effects, and also have a certain repair effect on cell DNA damage , and have a preventive effect on common cancers.

But do you know that there are also some rules for drinking tea? If you drink it wrong, it will not only fail to improve your health, but may even harm your body. Now, let's uncover the health traps of 4 kinds of tea and learn how to drink tea correctly.

Strong tea - drinking too much will damage your kidneys

Strong tea contains high levels of fluoride , which is mainly excreted through the kidneys. When the human body ingests too much fluoride, it will increase the burden on the kidneys. Once it exceeds the excretion capacity of the kidneys, fluoride will accumulate in the kidneys and cause damage to the kidneys.

In addition, strong tea contains a high amount of caffeine, which can easily cause brain excitement and lead to insomnia. It is also very irritating to the gastrointestinal tract. Especially for people with poor stomachs, drinking strong tea will stimulate gastric acid secretion and aggravate the condition.

So, how do you tell if the tea is strong?

A look at the color : the tea is very dark and a little cloudy;

Second taste : It tastes very bitter, without the sweetness of tea.

Hot tea can cause esophageal cancer

The high incidence of esophageal cancer in Chaoshan may be related to the habit of drinking hot tea. Hot drinks above 65°C can burn the mucous membranes of the mouth and esophagus. Long-term consumption may lead to abnormal cell proliferation and increase the risk of cancer. Currently, the International Agency for Research on Cancer has classified hot drinks above 65°C as Class 2A carcinogens .

suggestion:

Let the freshly brewed tea cool down a little before drinking.

When drinking tea, first touch the tea with your lips and make sure it is not too hot before drinking.

"Intestinal Cleansing Tea" - Damage to the Intestines

Many "laxative teas" and "intestinal cleansing teas" on the market seem magical, but they are actually dangerous. Most of these teas contain stimulant laxatives, such as rhubarb and senna , which have strong laxative effects. Long-term use will damage intestinal nerves, inhibit the normal contraction and peristalsis of the intestines , make the intestines "lazy", and become dependent on laxatives. Once you stop drinking laxative tea, the symptoms of constipation will often worsen.

Therefore, do not buy "laxative tea" on your own. If you want to use laxatives, it is best to take them under the guidance of a professional doctor.

Expired tea leaves: Toxins produced by mold may cause cancer

Tea is different from wine. The older the tea, the better it is. If tea is left for too long or stored improperly, it will easily go moldy and produce mold and toxins, especially aflatoxin , which is a first-class carcinogen and extremely harmful to the liver.

suggestion:

When buying tea, pay attention to the production date and shelf life.

When storing tea, ensure a dry, ventilated, light-proof environment.

If you notice that the tea has an unusual smell or color , stop drinking it immediately.

Tea is a good product for health preservation, but if you drink it incorrectly, it may become a health hazard. I hope that through today's sharing, everyone can drink tea more scientifically and enjoy the health and happiness brought by tea. Remember, the three principles of drinking tea are moderation, timing and suitability .
