Xinhuanet Harbin March 22 (Reporter Cheng Zilong) “Although everyone is drinking water every day, not everyone has the knowledge of safe drinking water. A considerable number of people have misunderstandings about safe drinking water. & rdquo; Liu Wei, director of the Food Safety Division of the Heilongjiang Provincial Bureau of Quality and Technical Supervision, said that safe drinking water has great knowledge.
Liu Wei introduced that there are three kinds of water that people often drink: tap water, mineral water and pure water, but people have misunderstandings when drinking these three kinds of water.
One of the misunderstandings: tap water is getting better and better.
Almost all people know that tap water boils and drinks best, but it doesn’t burn as well. When burning tap water, it is generally not too boiling. If it is too boiling, it is easy to produce some harmful substances such as chloride. Sometimes when boiling water, first open the lid and then turn off the flame, it is easy to make some harmful substances with water vapor.
Misunderstanding 2: Pure water can be used as long-term drinking water for households
Because pure water is very clean, long-term drinking will take away some trace elements in the human body, especially calcium in the human body. The loss, not to mention the addition of trace elements. Therefore, pure water should not be used as a household water for a long time. In particular, children should not drink pure water for a long time.
Misunderstanding 3: The more minerals in mineral water, the better.
The current public recognition of mineral water is very high, but some people think that “the more minerals in mineral water, the better.” . ” This view is not scientific. In fact, the excessive content of individual minerals in the water is also unfavorable to the human body. In addition, not all mineral water can be used as drinking water, and some mineral water must be scientifically treated to drink.
