Can water be boiled repeatedly, and is it good for water to be boiled repeatedly?

The answer is as follows: Can water be boiled repeatedly No matter who it is, there will be a theory that will tell us that water cannot be boiled repeatedly, and if it is boiled repeatedly, then this water cannot be used to drink. Because in the water we drink in our lives, it contains a small amount of substances called nitrate, in our chemical research this substance has been repeatedly boiled for a long time, nitrate this substance may slowly become another substance called nitrite, and such a substance has been studied to be a carcinogenic substance, if we drink repeatedly boiled water for a long time, then our body may be threatened by it, and it is possible to suffer from cancer for a long time. And this substance is very threatening, if you take a large amount of nitrite at one time, then it is equivalent to eating poison, and it may die in serious cases, so the water that is boiled repeatedly cannot be drunk for a long time.

In the past, researchers in our country have also done some experimental studies, that is, after heating the water repeatedly for 200 times, the nitrite value in the water is between three and four micrograms. In fact, this is more professional, I believe many people can't understand, is it more or less? Then our country has also set a standard for the content of this water, that is, the content of 100 micrograms in a liter of water is normal, so it means that the water that has been boiled repeatedly is in fact very small, and it can almost be ignored, so in most cases, it will not cause us to be poisoned, but it must be boiled repeatedly in a small amount, and such water cannot be drunk for a long time.

Many people here also know that what we experimented with and mentioned is basically bottled drinking water, so our domestic tap water has been repeatedly boiled, can we still drink it, which is also what everyone is more concerned about, because the kettle is almost all to boil tap water to drink, which in fact, there are researchers who have shown that there is no problem, the nitrite content is very small, negligible, so please put a hundred hearts to drink boiled water, However, if you drink this for a long time, you may still get sick, so drink less and try to boil it once and drink it all. The above is the explanation of the question of can water be boiled repeatedly, in fact, water is indispensable in our lives, we can't go because it contains some bad substances to give it up, no one can do it, water is the source of life, as long as we drink normally, there will be no problems, and we can't waste water, this is what we can do!

The nitrite content of repeatedly boiled water is still within the normal range and will not cause harm to the human body.

If you are used to drink, it is better not to burn it repeatedly. If it's used for something else, it doesn't matter.

No, it's not good for your health.

So that's why water can't be boiled repeatedly.

Can you drink water that has been boiled repeatedly?

It is not good to boil water repeatedly. Repeatedly boiled water has very little dissolved oxygen. Such water has no nutrients.

The solubility of oxygen in water is inherently small, and some of the oxygen is lost when it is boiled. If the water is boiled again, the oxygen dissolved in the water will decrease again, and it is better not to boil it repeatedly.

1. Fresh boiled water, boiled and drunk, is not only sterile, but also contains a variety of minerals required by the body. Do not drink water that has been left out for too long, do not drink boiled water that has been reboiled overnight in an automatic water heater, do not drink boiled water that has been boiled many times, and do not drink water that has been stored in a thermos flask that is no longer the same day, or water from a steamer that has been steamed. Although these "stale waters" are sterile, they cook out the minerals that the body needs, and may also contain some harmful substances, such as nitrites.

Nitrite is toxic to the body.

2. Boiling water contains a certain amount of nitrite, and if it is boiled repeatedly, the nitrite in the water will increase. Nitrite is a strong blood poison, which can oxidize the divalent iron in hemoglobin into trivalent iron after entering the human body in large quantities, so that the blood loses its oxygen-carrying function, resulting in hypoxic suffocation in the human body. Another dangerous potential toxicity of nitrite is that it can be combined with amines in the stomach to form nitrosamines, which are strong carcinogens.

Therefore, the water boiled for the second time should not be drunk.

3. If you often drink repetitive boiling water, it may cause tissue hypoxia, shortness of breath, chest dullness, purple lips and nails, or easy sleepiness. If it is more severe, nitrite enters the body and is likely to be converted into carcinogens nitrosamines after the action of stomach acid. Therefore, it is recommended to eat less water that is repeatedly boiled.

1. It is recommended not to boil repeatedly.

2. When boiling water is boiled repeatedly, calcium ions in the water are easy to precipitate out to form calcium carbonate. In addition, the water also contains a small amount of heavy metal ions such as copper, magnesium, and lead, and these heavy metal ions are precipitated and deposited after repeated boiling. It is recommended to drink boiled water all at once, or re-boil the water to drink.

Do not stop heating after the water boils, open the lid of the pot and continue to heat it for 1 2 minutes, which can remove chloroform, so that the water is filial to the calcium precipitation, and the taste of boiled water will be better. Fill the cup with boiling water to stop heating, pour boiling water into the cup, and wait until the water temperature reaches about 50 degrees, it is a cup of nutritious boiled water, it is recommended to drink 800ml a day.

2. When boiling water is boiled repeatedly, calcium ions in the water are easy to precipitate out to form calcium carbonate. In addition, the water also contains a small amount of heavy metal ions such as copper, magnesium, lead, etc., which are precipitated into silver and accumulated in the water after repeated boiling. It is recommended to drink boiled water all at once, or re-boil the water to drink.

Do not stop heating after the water boils, open the lid of the pot and continue to heat for 1 2 minutes, which can remove chloroform, make the water calcium precipitate, and the taste of boiled water will be better.

Boiled water can not be boiled repeatedly, because boiled water contains a certain amount of nitrite, if repeatedly boiled, the nitrite in the water will increase, nitrite is a toxic substance, long-term intake of nitrite will have adverse effects on the human body.

Boiling water, also known as boiled water, cool boiled water, frozen boiling water, light and tasteless, is the most drunk edible water in ordinary life.

Boiling water is a colorless and transparent liquid, because there is no addition of anything else to the mold, so it is also called boiled water, and it is called cool boiled water after cooling.

Boiled water that has been reboiled overnight in an automatic water heater, or boiled water left over from steamed meals and other foods that have been boiled repeatedly and repeatedly cannot be consumed.
