Overnight tea is a kind of tea that is soaked for a long time after soaking. This kind of physical tea is easy to deteriorate and breed some bacteria, which will be harmful to human health. In addition, overnight tea will also produce a lot of tannic acid, which is harmful to human health when combined with oxalic acid in other foods, and it will also endanger human health and easily lead to high incidence of stones. So usually drink tea as soon as possible after drinking tea, and don't drink overnight tea.
First, the harm to gastrointestinal health
Overnight tea is harmful to human gastrointestinal health, because it is easy to breed mold and various germs when stored for a long time. After drinking this healthy tea, people will let mold and bacteria enter the body, which is easy to harm the intestinal health, cause intestinal inflammation, and cause various uncomfortable symptoms such as abdominal pain and diarrhea. The gastrointestinal function of human body will be seriously damaged, and other foods cannot be digested normally.
Second, make the stone high.
Inducing stones is also the main hazard of drinking overnight tea, because overnight tea contains a lot of tannic acid. People will absorb sulfuric acid after drinking overnight tea, and sulfuric acid will react with oxalic acid in other foods to produce some substances that the human body cannot digest and absorb. After this substance accumulates in the body, it will produce stones, which will lead to the high incidence of gallstones and urinary calculi, which will seriously damage health.
Third, it causes cancer in the human body.
People drink overnight tea, which leads to subdivided cancer, because lotus leaf tea will produce some carcinogenic components in the process of long-term soaking. After the human body absorbs these substances, it will lead to cell canceration, leading to high incidence of cancer, which is not good for health. In addition, overnight tea will also produce some heavy metals, which will also endanger human health and cause some blood diseases. Overnight tea is harmful to human body, and it does a lot of harm, but it is aimed at those deteriorated overnight teas. If the tea soup stays overnight but does not deteriorate, it can still be drunk without obvious harm, but at this time, the nutrition in the tea soup has been lost a lot, and drinking it again will not have a good health preserving effect.
