What exactly does the kidney do?
The kidney is responsible for filtering impurities from the blood, maintaining the balance of body fluids and electrolytes, and ultimately producing urine that is discharged through subsequent pipelines; It also has endocrine functions to regulate blood pressure. To protect the kidneys, it is important to consume more water. Drinking tea can reduce the occurrence of kidney stones, but the wrong way of drinking tea not only fails to protect the kidneys, but also harms them. If you still have the following situations, it is recommended to avoid them as much as possible to avoid damaging your health.
01 Drinking tea while drinking can cause kidney damage
Some people believe that drinking strong tea after drinking has a "sobering" effect, which is a misconception. Drinking tea alone will not harm the kidneys, but if you drink tea while drinking or use strong tea to sober up, it may harm the kidneys.
Because alcohol enters the liver and is broken down into water and carbon dioxide through the action of enzymes, which are excreted from the body through the kidneys. And theophylline has a diuretic effect. The theophylline contained in tea can cause undecomposed acetaldehyde (alcohol is first converted into acetaldehyde in the liver, then into acetic acid, which is then decomposed into carbon dioxide and water) to enter the kidneys prematurely. Acetaldehyde has a significant damaging effect on the kidneys.
Drinking too much tea can damage the kidneys
Tea contains fluoride, and excessive consumption of tea can damage the kidneys. The reason is that the kidney is the main excretory organ for fluoride. When the body ingests excessive fluoride beyond the kidney's excretory capacity, it leads to the accumulation of fluoride in the body and a significant increase in the kidney's fluoride content.
03 Drinking too much tea can cause kidney damage
Tea is rich in oxalic acid, and frequent consumption of strong tea can lead to high oxalic acid urine, which can easily form calcium oxalate stones in the urinary tract, leading to kidney stones. Secondly, drinking too much tea can cause the kidneys to urinate frequently, thereby increasing the burden on the kidneys and damaging them. So, it is better to drink light tea in daily life, which is more beneficial for the body.
04 Drinking tea on an empty stomach
Some people are accustomed to drinking tea on an empty stomach just after waking up in the morning. In fact, tea contains a large amount of caffeine, which has a great stimulating and uplifting effect on the human body, thereby accelerating heart rate and causing panic. In severe cases, it can damage kidney function and affect physical health. Friends who love drinking tea should remember not to drink tea on an empty stomach, and can drink some plain water before drinking tea appropriately.
