Men drink tea and drink double kidney stones, which is healthier for long-term drinking of boiled water or long-term drinking of tea?

Mr. Liu, 37, was admitted to the hospital after drinking tea for a long time.

Six years ago, Mr. Liu had severe pain in the left waist and abdomen. At that time, he was diagnosed with kidney stones and hydronephrosis, and underwent minimally invasive surgery.

Unexpectedly, last year, Mr. Liu also had severe pain in the right waist and abdomen, and it was another kidney stone problem, but because the pain was relieved, Mr. Liu did not care.

It was not until September of this year that Mr. Liu, who wanted to procrastinate, suffered severe pain in his lower back after exertion , and then he rushed to the hospital for treatment.

The doctor conducted a comprehensive examination on Mr. Liu and found that he suffered from bilateral kidney stones , especially in the right kidney, and was accompanied by the performance of moderate hydrops . If it is not treated in time, the renal function is likely to be further damaged or lost.

Finally, according to Mr. Liu's condition and demands, the doctor prescribed a double mirror combined with minimally invasive nephrolithotomy for him. The postoperative analysis of the removed stones showed that the main components of the stones were calcium oxalate stones, which is in line with Mr. Liu's year-round love of drinking. Strong tea has a lot to do with it.

1. Who is healthier by drinking boiled water or tea for a long time?

There is actually no definite answer to this question. The "Dietary Guidelines for Chinese Residents" recommends drinking plain water or tea.

Boiled water is the most recommended water, although ordinary, it is also the healthiest.

In the process of boiling tap water, it can kill various microorganisms, and at the same time allow minerals to precipitate, and volatile chemicals in the water will also volatilize , which is the most economical and safe purification method.

It is not very reliable to say that repeatedly boiling water will cause cancer. After all, talking about toxicity without dosage is a hooligan. And even if the water is boiled more than 20 times, the nitrite content is lower than the national standard for drinking water. If I have to say that it is not good, it is very expensive to boil the water 20 times.

In addition, there was a saying on the Internet that "the shelf life of boiled water is only 16 hours". What is the truth?

The water has killed many microorganisms in the process of boiling, but after the water temperature drops to room temperature, the microorganisms will continue to enter the boiled water and multiply in the water. Therefore, the longer the boiled water is exposed to the air, the greater the number of microorganisms and the worse the natural water quality.

That is to say, boiled water does have a "shelf life", but it may not be accurate to 16 hours. All in all, just boiled open and cool boiled water will have better water quality than boiled water overnight or every few hours or days.

Drinking tea properly has many benefits for the body.

Drinking tea can increase the amount of water you drink, and the active substances such as tea polyphenols and chlorophyll in tea can help the body to strengthen its resistance. And because tea is rich in caffeine, drinking tea in moderation can be refreshing and diuretic. In addition, it also helps to supplement nutrients such as vitamins and minerals to a certain extent.

However, drinking tea can not completely replace drinking water , especially in the case of excess, it will make the benefits worse.

Excessive consumption of tea may cause gastrointestinal discomfort, cause rapid heartbeat, irregular heartbeat, insomnia, headache, frequent urination and other problems.

2. The more water you drink, the more serious the kidney damage?

First look at the relationship between water and the kidneys.

The water needs to enter the stomach through the esophagus after the entrance, and then enter the blood through the absorption of the digestive system. After the water reaches the blood, it will be filtered in the kidneys to form original urine, and the original urine will also be absorbed in the kidneys. During this process, nutrients will be absorbed into the blood, while ammonia-containing metabolites and salt-containing aqueous solutions are It will be excreted along the urethra.

Is drinking too much water bad for the kidneys?

For people with abnormal renal function, drinking more water may lead to changes in the body’s urination habits, causing problems such as polyuria, frequent urination, increased urine foam, hematuria, and even edema and other symptoms in severe cases.

Chen Zuhui, director of the Infection Control Department of the First Affiliated Hospital of Jinan University, once said that under normal circumstances, if there is not a lot of exercise or perspiration, drinking a lot of water at this time will put a burden on the kidneys and cardiovascular system.

Generally speaking, on the premise of drinking adequate and hygienic water, there is no problem for normal people to drink more water. The drinking habits that really hurt the kidneys are these two

• Drink water after thirst

When the feeling of thirst occurs, the body cells are often dehydrated. At this time, the central nervous system sends out a distress signal. If you drink water after being thirsty for a long time, the detoxification ability of the kidneys will be reduced, and the incidence of kidney disease will increase.

• Drink as water

Drinking beverages as water often will promote the excretion of calcium in the body due to the phosphates and sugars in the beverages, which will increase the calcium content in the urine and increase the risk of kidney stones.

3. Drinking three kinds of tea often may damage the kidneys and cause cancer

Tea can be said to be the favorite drink of Chinese people, but there are many kinds of tea leaves, and there are three kinds of tea, and drinking it often is actually not good for the body.

1. Strong tea damages the kidneys and hurts the body

The content of fluorine in strong tea is high, and fluorine is mainly excreted in the kidneys. If you often drink strong tea, once it exceeds the excretion of the kidneys, fluorine will continue to be in the body or cause "tea-type fluorosis". In addition, strong tea contains a lot of caffeine and theophylline, which are highly irritating to the stomach. The caffeine in strong tea can inhibit the absorption of calcium in the duodenum, and also accelerate the excretion of calcium in the urine, which may cause osteoporosis.

Generally speaking, from the sensory point of view, the taste of strong tea is too bitter, the color is strong, and even a little turbid. When the strong tea is cooled, a layer of tea oil will form on the surface. Can be regarded as strong tea.

2. Burnt tea may have carcinogens

If the tea is over-baked during production, it will produce a burnt taste, some of the effective nutrients will be destroyed, and it may even contain carcinogens. Therefore, whether from a nutritional or health perspective, it is best not to drink Jiaowei tea.

3. Too hot tea has the risk of cancer

Drinking tea when it is too hot may burn the mucous membranes of the mouth and esophagus, form ulcers, and increase the risk of cancer over time.

A study published in the International Journal of Cancer pointed out that compared with people who hardly drink tea and who like to drink herbal tea, people who drink more than two cups of hot tea at a temperature of 60°C a day have a higher risk of developing esophageal cancer 90%.

The "Dietary Guidelines for Chinese Residents (2022)" recommends drinking enough water, and a small amount of water frequently. In mild climates, adult men are advised to drink 1700ml of water per day in low physical activity conditions, and 1500ml for adult women. In addition, it is recommended to drink boiled water or tea in moderation, and drink less or no sugary beverages, and cannot replace boiled water with beverages.

Drinking water is actually a very basic health behavior. When people drink insufficient or unsafe water, the body is easily troubled by various health problems. Of course, drinking tea is also a good habit, but you should pay attention not to drink too much tea, and pay attention to avoid drinking strong tea, burnt tea and tea that is too hot.
