"Although everyone drinks water every day, not everyone has mastered the knowledge of safe drinking water, and a considerable number of people have misconceptions about it." Liu Wei, Director of the Food Safety Department of the Heilongjiang Provincial Bureau of Quality and Technical Supervision, introduced that there is a great deal to know about safe drinking water.
Liu Wei introduced that the three types of water people often drink are: tap water, mineral water, and purified water, but people have misconceptions when drinking these three types of water. Misconception one: The longer tap water is boiled, the better
Almost everyone knows that it is best to drink boiled tap water, but the longer it is boiled, the better is not true. When boiling tap water, it is generally not advisable to boil it for too long. If it is boiled for too long, it is easy to produce harmful substances such as chlorides. Sometimes, when boiling water, removing the lid before turning off the heat can easily cause some harmful substances to be discharged with the steam. Misconception two: Purified water can be consumed as household drinking water for a long time
Because purified water is very clean, long-term consumption will remove some trace elements from the human body, especially easily causing the loss of calcium in the body, let alone supplementing trace elements. Therefore, purified water is not suitable for long-term consumption as household drinking water. Children in particular should not drink purified water for long periods. Misconception three: The more minerals in mineral water, the better
Currently, the public's acceptance of mineral water is very high, but some people believe that "the more minerals in mineral water, the better." This view is not scientific. In fact, an excessive content of individual minerals in water is also harmful to the human body. In addition, not all mineral water can be used as drinking water; some mineral water needs to be scientifically treated before it can be consumed.
