When making tea and drinking tea, the teapot and teacup are not cleaned frequently. After a long time, more tea dirt has been accumulated in the teapot and cup, so someone gave it an elegant name of “tea mountain”.
Some people regard the “tea mountain” as a treasure, and even insist on it for several generations. It is said that with “tea mountain”, the state of “no tea fragrance” is reached. What’s more, it is said that “tea mountain” can cure diseases and save lives.
First of all, the so-called “no tea three Fen Xiang”, I think this is a typical case of giving up the root and chasing the end, or directly point is affectation. I’ve bought all the teapots. Do you still mean the tea? I’m afraid that no matter how bad the tea is, it’s better to brew it than the “Sanfen flavor”.
The more serious consequence is that “tea mountain” is not only unable to cure diseases and save lives, but also a fatal thing.
The drinking water used in tea making contains minerals and trace harmful heavy metal ions, such as cadmium, mercury, arsenic, etc. When the water is heated, with the increase of water temperature, the solubility of some calcium and magnesium ions decreases, and the concentration of insoluble salt increases. When the water is concentrated to a certain extent, the precipitation precipitates.
These precipitates will be washed with water into the teapot and cup. The tea that has not been drunk or has been placed for a long time is exposed to the air. The tea polyphenols in the tea and the metal elements in the rust will be oxidized, resulting in brown tea rust, commonly known as tea dirt, which is attached to the inner wall of the teapot and cup. The rust contains a variety of harmful metals such as cadmium, lead, mercury and arsenic, which is harmful to human health Kang’s chief culprit.
The content of these heavy metals is very small. If they are cleaned in time after each bubble, it will not cause any harm to the body; however, if they are not cleaned in time, they will be left to accumulate, and the content is increasing, and their harmfulness will gradually be revealed.
Li Hongzhu, an associate professor at Tianjin Pharmaceutical Research Institute, said: “tea stains contain toxic substances such as cadmium, lead, mercury, arsenic, and carcinogens such as nitrite, which will adhere to the smooth surface of the tea cup. As tea enters the body and into people’s digestive system, it combines with protein, fatty acid and vitamin in food to form insoluble precipitation, which not only hinders the human body’s absorption and digestion of these nutrients, but also damages the gastrointestinal and other organs. In addition, often do not clean the tea cup, but also leave more scale, which also contains a large number of heavy metals, very harmful to health
At the same time, these oxides into the body will also cause nervous, digestive, urinary and hematopoietic system lesions and functional disorders, and even lead to premature aging, especially arsenic and cadmium can cause cancer, cause fetal malformation, harm to health.
Therefore, do not superstitious so-called “tea mountain” said, found tea dirt, timely cleaning, for clean, for health.
