This statement is related to nitrites, in fact, there is no scientific reason. If reaching nitrite is harmful to our body, reaching a toxic dose, or combining with ammonia in our body to produce a carcinogen, this water should be boiled at least 300 times or more.
Experiments have proved that the water that is boiled four times repeatedly, the nitrite content is not much different from the tap water, and it is far from the amount harmful to health.
Therefore, under normal circumstances, drinking water that is boiled three or five times repeatedly will not cause cancer. However, if the storage conditions are not good, it may fall to ashes, or breed other bacteria, it is best to store it in a closed way, or drink it and burn it now. According to the analysis of the Jianding Officer of "Medical Zheng Audio-Visual", repeated boiling water will cause cancer, which is a rumor!
