Tea water left overnight cannot be drunk.
One. Dangers of overnight tea:
1.Tea contains tea polyphenols, which are easily oxidized into brown gelatinous substances in air and water, that is, tea rust. Tea rust contains a variety of substances such as pickaxe, lead, arsenic, mercury, etc.
The longer the tea water is exposed to the air overnight, the more the amount of tea polyphenols oxidized into tea rust will be. When tea rust enters the human body, it binds and precipitates with proteins, fats and vitamins in food, which will hinder the absorption and digestion of nutrients.
2.Once these oxidizing substances enter the human body, they can also cause inflammation, necrosis and other lesions in organs such as kidneys, liver and stomach. Therefore, tea leaves left overnight should not be drunk, and tea utensils should also be scrubbed frequently.
3.The temperature is high in summer, and the tea is easy to deteriorate, if it is left for more than 24 hours, it is best not to drink it, and some elderly people with weakened resistance can easily cause diarrhea.
4.Most of the vitamins have been lost due to the long time of the overnight tea water, and the proteins and sugars in the tea have become nutrients for the reproduction of bacteria and molds, so it is not suitable for drinking.
Two. A misconception about overnight tea.
Drinking overnight tea water will cause cancer, this statement is not correct, long-term tea will produce nitrite, but nitrite itself is not carcinogenic, only nitrite into the human body and gastric acid, the formation of nitrosamines, is a strong carcinogen, and liver cancer and other diseases are closely related.
The nitrite content is a safe dose within a certain range, and the nitrite content produced by overnight tea does not exceed the unit of this safe dose, which also shows that the statement that overnight tea water will cause cancer is actually false.

The so-called tea rust is "tea polyphenols oxidized into brown gelatinous substances in air and water", "tea rust contains lead, iron, arsenic, mercury and other substances", "tea rust enters the human body, combines and precipitates with proteins, fats and vitamins in food, and hinders the absorption and digestion of nutrients".

Tea water can be drunk overnight.
The tea leaves made before going to bed at night, and when I got up the next day to drink them, the tea leaves did not deteriorate, and of course there was no problem with drinking. If the tea leaves are steeped for too long, especially if the temperature is high, it will lose its green color and increase the degree of yellowness. This is the oxidation product of the oxidation of tea polyphenols in tea to form yellow-red and reddish-brown, mainly theaflavin, thearubigin, theabrownin, etc.
These products are non-toxic and do not cause harm to the human body. This change is day and night, and the temperature is higher during the day, and the change is a little bigger. But if the tea is soaked for too long, bacteria will breed and deteriorate, of course, you can't drink it, and it doesn't matter if you drink it for no more than 24 hours.
