Uncle Li, who is 65 years old, is a tea lover who has always felt that plain water is bland and tasteless. Therefore, he is accustomed to drinking tea every day. When he is thirsty, he "hoards" tea and almost never drinks plain water. Moreover, as we age, it may be due to the degradation of taste buds,Uncle Li particularly enjoys drinking strong tea, and in just six months, he used up 10 pounds of tea leaves.

Just last week, Uncle Li suddenlyUnbearable abdominal painHe was sent to the hospital for examination by his family, and the doctor found that heThe kidneys are densely packed with stonesMultiple indicators such as uric acid and creatinine exceed the standard, resulting in severe kidney damage.

After learning that Uncle Li has a habit of drinking strong tea, the doctor quickly advised him to quit this habit, and in the future, he should not drink tea as recklessly as before. He should drink more water and less tea!

Isn't drinking tea beneficial to health? Why does the doctor want Uncle Li to drink less tea? Uncle Li and his family all expressed their lack of understanding. The doctor told them,Generally speaking, there is no risk in normal tea drinking, but drinking too strong tea, too much tannin, Theobromine and other ingredients may lead to the formation of Kidney stone disease.

China is a major tea country, with an annual consumption of over 2 million tons of tea. Have a cup of hospitality when greeting guests, a reminder when feeling sleepy, and a cup of health preservation in your leisure time. Tea is almost a part of everyone's life. Whether domestically or internationally, drinking tea is often seen as a healthy habit, but in fact, drinking tea should also be moderate, otherwise it may harm the kidneys.

New research from Southern Medical University: Drinking more than 3.5 cups of tea every day may increase the risk of kidney injury

The idea that drinking tea can preserve health and is beneficial to health has been deeply rooted in people's minds. However, drinking tea should also be moderate. A recent study from Southern Medical University may break your understanding of tea.

In May, Nutrients, an internationally renowned journal, published a study on the relationship between tea drinking in Southern Medical University and new Acute kidney injury. Researchers believed thatThere is a reverse "J" type relationship between drinking tea and new kidney injury. Moderate drinking of tea is beneficial for protecting the kidneys, but drinking tea above a certain threshold may actually increase the risk of new kidney injury.

The researchers collected the data of 498621 people from the Biobank in the UK. 85.3% of these people have the habit of drinking tea, and 40.5% of them drink 3 to 5 cups of tea every day. After a median follow-up of 12 years, 4.3% of the patients had new Acute kidney injury.

Through analysis, it was found that,When drinking less than 3.5 cups of tea a day, the risk of new Acute kidney injury gradually decreases, reaching the lowest risk at 3.5 cups, and after more than 3.5 cups, the risk of new Acute kidney injury tends to increase.

Another interesting discovery may make people who like milk tea happy. Adding sweeteners to tea will offset the preventive effect of tea on new Acute kidney injury,Adding milk can reduce the risk of new Acute kidney injury caused by drinking a lot of tea..

Does this study mean that drinking tea can harm the kidneys and prevent the enjoyment of tea in the future? The researchers' suggestion is that,Maintain a mild or moderate habit of drinking tea, adding milk is also acceptable, and it is not recommended to completely avoid drinking tea.

It is worth noting that this study focuses on foreigners,Whether the conclusion applies to Chinese people is still an unknown number.
