When friends get together, they usually entertain their friends with tea. Besides meeting friends, they often drink it at home, but do you know that drinking tea is harmful to the kidneys?
Does drinking tea have an effect on the kidney?
Drinking tea has a beneficial effect on the kidney. No matter what kind of tea, tannic acid, catechin and vitamins have special effects on regulating blood lipid and uric acid, especially raw Pu 'er tea. Those with obesity, high blood lipid and high uric acid might as well try it. The daily drinking amount is controlled at 5-1g, which has the function of removing stones for patients with kidney calculi.
drinking tea alone won't hurt your kidneys. If you have the habit of drinking tea at the same time, it may hurt your kidneys. Because the alcohol in wine will be converted into acetaldehyde, the alkaloids in tea will have a strong diuretic effect, and acetaldehyde will enter the kidney before it can be decomposed. Because acetaldehyde is toxic, it will damage the kidney and hurt the kidney.
Some people are used to drinking tea on an empty stomach as soon as they get up in the morning. In fact, tea contains a lot of caffeine, which will accelerate the heart rate and lead to palpitation, and promote kidney urination and increase the burden on the kidney. Drinking too much tea will make the kidneys urinate frequently, which will increase the burden on the kidneys and hurt them.
Generally speaking, drinking tea is beneficial to human body, but it is harmful to human body if it is unreasonable.
The World Health Organization has investigated the advantages and disadvantages of beverages in many countries, and finally concluded that:
Tea is the best beverage for middle-aged and elderly people
According to scientific determination, tea contains protein, fat, more than 1 vitamins, and nearly 3 components such as tea polyphenols, caffeine and lipopolysaccharide, which can regulate physiological functions and play various health care and pharmacological roles.
Because tea can prevent the increase of sterols in human body and prevent myocardial infarction, tea polyphenols can also remove excessive free radicals and inhibit and kill pathogenic bacteria. In addition, tea has the functions of refreshing, eliminating fatigue and resisting bacteria. This is necessary for middle-aged people. It can also purify water quality and reduce the harm of radioactive substances to human body. Therefore, people who live in cities, especially, should drink tea more often in the current situation of serious natural environmental pollution.
Drinking tea depends on physical fitness
Traditional Chinese medicine believes that people's physical fitness can be divided into dryness and heat and deficiency and cold, and tea can be divided into coolness and warmth through different production processes, so drinking tea with different physical fitness also requires attention. People with dry and hot constitution should drink cool tea, while those with deficient and cold constitution should drink warm tea.
It's best to drink black tea at night
Because green tea belongs to non-fermented tea, the content of tea polyphenols is high, and it maintains its original properties, which is more irritating; Black tea is a fully fermented tea. Although the content of tea polyphenols is low, it is mild and mild after "aging", so it is suitable for drinking at night. Especially for people with weak spleen and stomach, adding some milk when drinking black tea can play a certain role in warming the stomach.
However, people who are easily excited or sensitive, have poor sleep and are weak at ordinary times should drink less or not drink tea at night. In addition, when drinking tea at night, you should put less tea leaves and don't make the tea too strong. It is best to drink tea after dinner, because drinking tea on an empty stomach will hurt your health, especially for people who don't drink tea often, it will inhibit the secretion of gastric juice, hinder digestion, and seriously cause palpitations, headaches and other "tea drunk" phenomena.
How to drink tea without hurting the kidneys
If you want to avoid this situation, you should learn to drink tea correctly, and keep in mind the following points:
1
Don't drink tea on an empty stomach
Many friends who like tea often drink it whenever they want, without paying attention to the drinking time, which is actually very harmful to their health. Especially drinking tea on an empty stomach, tea contains a lot of caffeine, which has a certain stimulating effect on the body and can promote renal urination. Drinking on an empty stomach can easily increase the burden on the kidney and even damage the renal function. Therefore, I am here to tell all tea lovers not to drink tea on an empty stomach.
2
Don't drink strong tea
Almost all tea leaves contain caffeine. If the tea is too strong, the caffeine in the tea soup will increase, which will also increase the degree of stimulation to the body, which will further encourage the kidneys to urinate frequently and increase the burden on the kidneys, thus damaging the kidneys. Therefore, please be careful when drinking tea, and try to avoid drinking strong tea.
3
Avoid drinking tea and wine.
Drinking tea correctly, moderately and alone won't hurt your kidneys, but if you drink tea at the same time, or drink tea immediately after drinking, it will probably hurt your kidneys. Because alcohol can stimulate the human body, and tea can also stimulate the human body, drinking both together will increase the stimulating effect on the kidney, which is not conducive to the health of the kidney.
