Many mineral water will mark the contents of calcium, magnesium and potassium on the package, and in the propaganda, it is claimed that "the water contains many natural minerals and trace elements needed by human body such as calcium, magnesium and potassium". It gives people the feeling that this water is an important source of calcium, magnesium and potassium. In fact, compared with food, water has effects on calcium, magnesium and potassium. Not much has been done.
Returning to the actual market, at present 95% of mineral water in China is strontium mineral water or metasilicate mineral water. It has been found that strontium is beneficial to maintaining the health of teeth and bones, while silicon may play a role in growth and bone formation. However, mineral water is not the only source of strontium and silicon. Strontium and silicon can also be obtained from human body through food.
In addition, there are some bottled water labeled "Drinking Natural Water" and "Drinking Natural Spring Water" on the market, which can easily be mistaken for mineral water, but it is not. (Gu Chuanling, Deputy Secretary-General of Capital Society of Health, Nutrition and Food)
