Can you drink water that has been boiled many times, and can you still drink boiling water after boi

Can you drink water that has been reheated repeatedly? This is a question that exists in the minds of many people, many people think that if the water is heated repeatedly to drink, it is easy to cause the nitrite content in the water to rise, or drinking the water after repeated heating, there is a possibility of poisoning? Is this true?

Why is nitrite found after drinking water is repeatedly boiled?

Many people think that if the water is boiled repeatedly, it cannot be drunk. This is because drinking water contains a certain amount of nitrate, and if it is cooked for a long time, the nitrate in the water may slowly convert to nitrite due to high temperatures. Nitrite is a carcinogen, and eating too much of it can easily cause great harm to your own health.

If it is said that excessive nitrite content is ingested at one time. It can easily lead to acute poisoning and even death. In this regard, we need to do something to stop drinking water that contains a lot of nitrites.

How much nitrite is in boiled water?

After measurement studies, it was found that if the bottled drinking water was heated 200 times, the nitrite content in the water was basically between 3-4 micrograms per liter. I believe you must be very unfamiliar with this concept, I don't know what this concept is? Basically, the nitrite content in China, the limit value in China is 100 micrograms per liter, and the nitrite value in repeatedly heated water is far lower than the standard value defined in China.

In this regard, if we reheat drinking water repeatedly, it will not cause us nitrite poisoning.

Many people will ask, this is all about bottled drinking water, if it is said that tap water is repeatedly heated, can it still be drunk? This question is also confusing. In fact, there is no need to worry too much, the water that has been heated repeatedly can also be drunk.

It doesn't have any impact on our health, and if we like to heat the tap water repeatedly, it's not too much of a problem.

Is it OK to drink water after a long time apart while it is heated?

If boiled water has been left in the kettle for a long time, we don't need to heat it for drinking. This is because, if you say, the water has been sitting there for a long time. There may be a lot of bacteria and microorganisms in the water.

At this time, we are heating, and these vitamins have been killed even though we have already killed them.

However, there may also be some odors that may cause us to have difficulty swallowing, causing us to have diarrhea and abdominal pain. It's a very bad thing for health.

Can you drink water that has been boiled multiple times? Professional thinks to answer for you!

OK. After repeated heating of boiling water, it was found that the nitrite content did increase with the increase of heating times, and after 52 repeated heating, the nitrite content in the water was micrograms. After heating to 181 times, the nitrite ion content in the water is micrograms per liter, and the hand is 5 times as late as at the beginning.

Seeing this "increase to 5 times", Da Huaidou does not need to panic. Although this figure exceeds the sanitary standards for drinking water in our country, it is still safe. Many people like to eat ham sausages with much higher nitrite content than this:

The allowable amount of nitrite in qualified ham sausage is 30,000 mcg (30 mg) per kg.

The ham is still safe, and there is no need to worry about the nitrite in the water. Generally speaking, the ordinary electric kettle at home does not hold much water, and it has been drunk long before it has been heated a few times, so the boiling water that has been boiled many times is also safe.

Water that has been boiled twice can be drunk, but it is not recommended to drink water that has been boiled repeatedly. Not good for the body.

Water is a very important part of the human body, 80% of the human body is water, so drinking water is particularly important in people's daily life, so what is about thousands of boiling water? What are the disadvantages of drinking thousands of boiling water? Let's take a look!

Bad habit 1: The water dispenser is never washed.

Bottled water and water dispensers are no longer common in homes, offices, and public places, and the water dispensers used have never been cleaned since they were placed there. The water dispenser seems to make people drink good quality water, but in fact, the "secondary pollution" is very serious. Whenever you turn on the tap of the water dispenser, you hear a "grunting" sound, and a string of bubbles turns out of the bucket, which means that air enters, and dust and microorganisms will be brought in.

According to the test data of the national environmental health monitoring department, the cold and hot water bile in the bottled water dispenser will multiply a large number of bacteria, such as Escherichia coli and staphylococcus, if not washed for 3 months. So, it's best to clean it once a month and every two weeks in the summer. The water dispenser in the office needs to be cleaned frequently because of its frequent use.

Bad habit 2: Drink tap water as soon as it boils.

It is a good habit to drink boiled water, but the water cannot be drunk as soon as it is boiled, because the tap water is chlorinated and disinfected, in which chlorine combines with the residual organic matter in the water to produce halogenated hydrocarbons, chloroform and other carcinogenic compounds.

When boiling water, you may wish to take three steps: first, take the tap water out and leave it for a while before boiling; When the water is about to boil, open the lid of the kettle; Finally, if the water is boiled and then turned off after 3 minutes, the chlorine content in the water will be reduced to the safe drinking standard, which is truly "boiling water". The polyester bottles used in bottled water often contain substances that may cause chronic poisoning in the human body, especially when the bottle is in a high temperature environment, or if it is not drunk in time after opening, harmful substances will seep into the water and endanger health.

Nowadays, there are more and more households using electric kettles, and many people can't drink the water boiled at one time, and then boil it again after a while. Bring the water to a boil and drink it as soon as possible, and do not reheat it repeatedly. Many people are worried about whether the water in the water dispenser is a thousand boiling water, due to material limitations, the maximum temperature of the water in the water dispenser is generally about 90 degrees Celsius, which cannot reach the state of boiling, and it is not a thousand boiling water.

However, the best drinking time for bottled water is 1-15 days after leaving the factory, once it exceeds 15 days, there are too many bacteria in the water, and it is not suitable to drink again.

It is drinkable to boil the water on both sides, Yan Xun because the water is Hongxiangwide in a short period of time without any problems, of course, it is not recommended to boil it many times, otherwise there will be nitrate precipitation.

OK. From a health point of view, boiling water can be boiled for the second time, usually said can not drink a thousand boiling water, not the second boiling water, but repeatedly boiled water, water will be vaporized when boiling, repeated and many times to boil will lead to a large number of mineral components remaining in the remaining water, the concentration is very high, after drinking will increase the risk of liver, kidney, stomach, intestinal stones, and the mineral concentration in the water boiled twice can not reach the pathogenic concentration at all, you can drink.

Repeatedly boiled water can be drunk.

In 2011, Harbin Institute of Technology conducted relevant experiments on this. The researchers took six beakers, raw water and water that had been boiled 1 to 5 times, and determined nitrite, nitrate and other substances. The results showed that the presence of nitrite was not detected after repeated boiling of tap water that met the national standard, and even if a certain amount of nitrite was artificially added, its content did not change during the boiling process.

Others have repeatedly heated the bottled water 20 times and found that the nitrite content in the water exceeded the standard, reaching micrograms, exceeding the standard micrograms. What if the heating is more frequent? The results of the study showed that after heating the bottled water 181 times, the nitrite ion content was five times higher than that of micrograms per litre.

Although this figure exceeds the sanitary standards for bottled water in our country, it is still safe.

Boiling water boils and boils again to drink. Boiling water is boiled and boiled twice, as long as the water itself is not contaminated, it can be drunk. However, it is not recommended to boil the water repeatedly or boil it for too long to drink, because the water may be contaminated and will have an impact on human health.

Repeatedly boiling water, may have a greater risk of bacteria in the water, bacteria and dust in the water may affect the human body, and it is difficult to ensure that the boil to 1, bacteria can not be guaranteed to be destroyed, if the drinker has weak gastrointestinal function, may have diarrhea, bloating and other uncomfortable symptoms. In addition, if the water boiled a few days ago is boiled a second time, there is a greater possibility of unclean substances, and it is not recommended to continue drinking.

It is recommended to drink the boiled water on the same day, if the boiled water is not drunk on the same day, special attention should be paid to the storage environment and method, such as covering the lid to avoid foreign objects falling into the water and preventing contamination by bacteria in the air.

Boiling water is drinkable after boiling it twice. At present, there is no scientific evidence to prove that water that has been boiled twice cannot be drunk, and medical studies have also stated that the composition of water that has been boiled repeatedly is basically the same as that of the water that has been boiled for the first time, so it is safe to drink boiled water after boiling twice.

Hello Boiling water can be boiled twiceFrom a healthy point of view, boiling water can be boiled a second time.

Repeatedly boiled water, the water will vaporize part of the water when boiled, repeated boiling will cause a large number of mineral components to remain in the remaining water, the concentration is very high, after drinking will increase the risk of liver, kidney, stomach, intestinal stones, and the mineral concentration in the water boiled twice can not reach the pathogenic concentration at all, you can drink.

Overnight water or boiled water stored for a long time should not be boiled a second time.

Question: Can I drink cold water with boiling water?

If it's raw water, that is, tap water, don't drink it like this Question: What is the harm to the body of drinking such water?

Boiling water twice is drinkable, and the so-called boiling water refers to the water that has been boiled repeatedly, because the nitrite content in the water is not up to standard, and it will not pose much threat to our health. However, boiling water that has been boiled many times will produce a large number of minerals, and the concentration of these minerals is very high, which will increase the load on the liver, stomach and intestines and kidneys, so don't drink too much of this water. For the sake of your health, drink new water.

The water that is boiled twice is not a thousand boils, it is drinkable, and the minerals in it are not harmful to the body. If you boil water for the second time, it is the day before, or a few days ago, it is recommended not to boil it for drinking. It is best to drink it on the same day, and then boil it in the afternoon, which is okay and will not hurt the body.

It is okay to boil water twice to drink, but it is best not to boil it too often.

If you burn it today, you will burn it again tomorrow, and it is better not to drink such boiling water, because it takes too long.

Drinkable, no problem.

You can drink it, of course you can drink it, what can't you drink, will you be poisoned to death?
