After the boiled water is cooled, it is comparable to a chronic poison? Can you drink it? CCTV experiment tells you the truth
Experts advocate that we should drink more water to meet the water needs of the human body, and at the same time promote the metabolism in the body, which is more conducive to the health of the human body, especially boiled water, which is a healthy drink recommended by many experts.
However, it was previously reported on the Internet that after the boiled water is cooled, it is comparable to a chronic poison, and the boiled water is actually poisonous. Is it true or false? Take a look at what the CCTV experiment has to say!
1. Repeatedly boiling boiled water will cause cancer?
It is reported on the Internet that "repeatedly boiled nitrates in water will form nitrites, which may cause cancer in the body". Does boiled water that is repeatedly boiled really cause cancer?
The Guangdong Provincial Food Inspection Institute once conducted an experiment with thousands of boiling water. The researchers repeatedly boiled tap water and drinking pure water, and monitored them regularly. The results found that the nitrite content in the water that was boiled several times was much lower. It is within the national standard limit , so it is safe to drink without worrying about cancer.
2. Is boiled water a chronic poison after cooling down?
There are many rumors about drinking water on the Internet. Is boiled water really comparable to chronic poison after cooling down? Is it really impossible to drink the cold boiled water?
In fact, boiled boiled water is very safe, but if the environment is not clean, it may be infected by some microorganisms after a long time, and the taste will become worse.
However, after two days of boiled water, the colony is always obviously exceeding the standard. Therefore, it is recommended not to store the boiled water for a long time, so as not to affect the health of the body.
It is recommended that if the boiled water is stored for more than two days, it should be drained as soon as possible.
Three, drink water, pay attention
Drinking water seems to be a small thing, but it is actually very particular. Healthy drinking water is the most beneficial to health.
1. Special populations should control the amount of water they drink
For special groups such as patients with liver ascites, heart failure, and glaucoma, it is recommended to drink a small amount of water several times as much as possible to avoid drinking too much water at one time, which may lead to aggravation of the disease.
2. Make sure to drink enough water every day
The dietary guidelines for Chinese residents suggest that adults should drink enough 1500-1700 ml of water every day, and try to drink boiled water and avoid replacing water with beverages.
3. Avoid binge drinking after strenuous exercise
After strenuous exercise or engaging in heavy physical exercise, the increase in sweating will lead to the loss of salt. It is necessary to avoid drinking too much water at one time to avoid water poisoning.
Studies have found that thousands of boiling water does not actually cause cancer. If the boiled water is left to cool for a short time, it will not affect drinking. When drinking water, you must pay attention to drinking water correctly. It is necessary to ensure sufficient drinking water and distinguish between different situations. Special groups should drink a small amount of water several times.
