Can you drink repeatedly heated boiled water? netizens have been cheated for so many years.
After the water is boiled repeatedly, the content of nitrite will increase, and nitrite may cause cancer and be harmful to the body. So can this kind of "boiling water" which is boiled repeatedly be drunk or not?
The researchers did such an experiment to determine the content of nitrite in raw water, boiled water once and boiled five times respectively. The results showed that no nitrite was detected after the standard tap water was boiled repeatedly.
The content of nitrite ion in the water was detected to increase to 3.52 micrograms / liter after repeated heating with the water cooler for more than 180 times. the content of nitrite in qualified ham sausage was no more than 30000 micrograms / kg. In comparison, this nitrite in "Thousand boiling Water" is negligible.
It is worth reminding that after the boiled water has been preserved in the thermos for a long time for 5 days, the content of nitrite will indeed increase due to the action of bacteria, so after boiling the boiled water, drink it as soon as possible, do not keep it for a long time! In short, "thousands of boiling water" can be drunk, but do not drink boiled water that has been stored for too long.
