What water is the healthiest to drink at ordinary times?

Drinking back running water is the healthiest. At present, the drinking water of many urban residents is mainly boiled water (tap water) and pure water. Let's talk about why drinking boiled water is not good for your health. Boiling water can only play the role of sterilization. In the past, it was ok when there was no chemical pollution in tap water. Now tap water is seriously polluted. After boiling water, harmful substances such as heavy metal ions, carcinogens and organic pollution cannot be removed (three main ways of tap water pollution in China: 1. Water pollution: according to the statistics of the national environmental protection department, 82% of rivers in China are polluted to varying degrees; 78% of the river reaches in urban waters are not suitable as drinking water sources. The industrial pollution and chemical pollution of urban sewage are becoming more and more serious. 2. Secondary pollution: After the tap water leaves the factory, it passes through a long water pipe network, water tower and water tank and comes into contact with many pollutants. According to the detection of Institute of Environmental Health Monitoring of Chinese Academy of Preventive Medicine, the compliance rate of drinking water in 35 big cities in China is only 23%. 3. Potential hazards caused by disinfection methods: At present, most water plants generally adopt traditional treatment processes of sedimentation, filtration and chlorination. Chlorine is the main killer of cancer and heart disease, which is harmful to human health. Then you may say, I have been drinking tap water for decades, why can't I get cancer? In fact, the occurrence of cancer is related to many factors, mainly our diet, living habits, living environment and mental health. Among them, water is an important part of diet, and water is often an important nutrient that is forgotten. According to the World Health Organization, 80% of diseases and 50% of children's deaths in the world are related to poor drinking water quality. Tap water is safe at best, which is far from healthy water. Drinking for a long time is not good for people's health. Why is pure water unhealthy? Pure water is made by filtering tap water and other water with reverse osmosis membrane (RO membrane). The filtration accuracy of RO membrane is 0.00 1 micron, which filters all substances in tap water, without minerals and trace elements, which will cause great side effects to growing children and osteoporosis and various diseases to middle-aged and elderly people due to lack of trace elements. As early as 1997, the Shanghai Municipal Education Commission issued a document: students in primary and secondary schools and kindergartens are prohibited from drinking pure water, so as not to endanger the growth of seedlings in the motherland. In addition, the biggest problem of pure water is not that it contains no minerals and trace elements, but that the PH value is lower than 7.0. , weakly acidic. Long-term drinking is tantamount to creating an environment for cancer survival. (Normal people's blood PH is 7.35-7.45, and most cancer patients' blood PH is below 7.2) Because cancer patients first acidify their constitution and then induce cancer. So what kind of water is healthy water suitable for human consumption? Healthy water refers to water that can improve and enhance human physiological efficacy, enhance human health and improve the quality of life on the basis of satisfying basic physiological functions and life maintenance. According to the drinking water quality standard published by the World Health Organization, healthy water is summarized as follows: 1. Does not contain substances that are toxic, harmful or have peculiar smell to human body; 2. The hardness of water is moderate; 3. The content of minerals needed by human body is moderate; 4. Dissolved oxygen and carbon dioxide in water are moderate; 5. The water mass is small (<100Hz); 6. Water has strong nutritional and physiological functions (solubility, permeability, emulsification); 7. number seven. The PH value is weakly alkaline. Returning water is a brand-new "water species". It adopts the fourth generation of high-tech "washing water" technology to filter all harmful substances most thoroughly and retain trace elements and minerals necessary for human body. It's really close to natural mountain springs. Wuhan Guanglian Trading Co., Ltd. is a professional company specializing in the research, development and sales of water appliances.
