2. Pure water has lost its positive physiological function because of its purity (except trace elements and minerals beneficial to human health) and has become "stagnant water" with degraded functions.
Long-term drinking can easily lead to sub-health problems such as weakness of limbs and listlessness, which is especially unfavorable to the development of fetuses and children.
A senior doctor studying water in the United States pointed out with a large number of detailed data that the ideal soluble total solid content of drinking water is 300mg/l, the total hardness is about 170mg/l, and its pH value should be alkaline, which is quite beneficial to the prevention and treatment of cardiovascular and cerebrovascular diseases. Many developed countries stipulate that the hardness of drinking water is not less than 60 mg/L.
3. Pure water is weakly acidic water (pH value is 5? 7) Long-term drinking will destroy the normal acid-base balance of human body and lead to acidification of human body. Leon, an American medical scientist and Nobel Prize winner, believes that acidic constitution is the source of all diseases.
4. Pure water has strong solubility. After drinking a lot, the original trace elements and nutrients in the body will be quickly dissolved in pure water and then excreted, which will make the nutrients in the human body lose balance, leading to malnutrition and decreased immunity.
At present, there are few positive reports about pure water to human health. On the contrary, many biomedical experiments and epidemiological investigations show that drinking pure water for a long time will have a negative impact on human health.
6. The United States, Western Europe, Japan and other developed countries have not included pure water in the category of drinking water, nor have they seen any national standards for drinking pure water in any developed country. The China Consumers Association has also officially issued a consumer warning that young children and the elderly should not drink pure water for a long time.
