Is boiled water like a chronic poison after cooling down? Can I drink it? CCTV experiment tells you the truth
Experts advocate that we drink more water to meet the water needs of the human body, and at the same time promote metabolism in the body, which is more beneficial to human health, especially boiled water, which is a healthy drink recommended by many experts.
However, it was previously reported on the Internet that boiled water is comparable to chronic poison after being cooled, and boiled water is also poisonous. Is it true or false? Take a look at the CCTV experiment, what exactly is it saying!
1. Can repeated boiling of plain water cause cancer?
It is said on the Internet that "nitrate in water will form nitrite after repeated boiling, and drinking it may cause cancer in the body." Does the boiled water that is repeatedly boiled really cause cancer?
The Guangdong Provincial Food Inspection Institute once conducted a thousand-boiling water experiment. The researchers repeatedly boiled tap water and purified water for drinking, and carried out regular monitoring. The results found that the nitrite content in the water that was boiled several times was far lower. It is lower than the national standard limit , so it is safe to drink without worrying about carcinogenicity.
2. Is boiled water a chronic poison after letting it cool?
There are many rumors about drinking water on the Internet. Is plain boiled water really comparable to chronic poison after cooling down? Is the cold boiled water really undrinkable?
In fact, boiled boiled water is very safe, but if the environment is not clean, some microbial infection may occur after a long time of storage, and the taste will also deteriorate.
However, if the boiled water has been left for two days, the colonies are always significantly exceeded. Therefore, it is recommended not to leave 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 has been left for more than two days, it should be poured out as soon as possible. Don't blindly save, but harm yourself virtually.
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 your health.
1. Special groups should control the amount of drinking water
For patients with hepatic ascites, heart failure, glaucoma and other special groups, try to drink a small amount of water multiple times to avoid drinking too much water at one time, which will lead to aggravation of the condition.
2. Make sure to drink enough water every day
The dietary guidelines for Chinese residents suggest that adults should drink 1500-1700 milliliters of water every day, and try to drink plain water as much as possible, and avoid using beverages instead of water.
3. Avoid binge drinking after strenuous exercise
After strenuous exercise or heavy physical exercise, the amount of sweating increases, which will lead to the loss of salt. Avoid drinking too much water at one time to avoid water intoxication.
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. If it exceeds two days, it must be poured out in time. When drinking water, you must pay attention to drinking water correctly. It is necessary to ensure sufficient drinking water and to distinguish between different situations. Special groups should drink water in small amounts and frequently.
