Chinese green food development center said: "safe, high quality, nutritious" embodies the quality characteristics of green food. The first characteristic is its safety, that is to say, in a reasonable way of consumption and normal consumption of food will not cause harm to the body's characteristics. As we all know, an adult needs to drink about 2000 milliliters of water every day to maintain the balance of water income and expenditure. If an adult drinks about 2000 milliliters of pure water every day, will it cause harm to the body in the long run? Beijing University of Chemical Technology Water Resources Research Center, Professor Jin Riguang said: "Pure water water molecules are extremely tandem and linear grouping structure, not easy to pass through the cell membrane, which will lead to the loss of beneficial life-related elements in the body to the outside of the body, some sensitive people drink the more the more the thirst is not quenched, the more they drink the more they want to drink, lowering the body's immunity, and even cause some kind of disease." China's cardiovascular disease experts, the Chinese Academy of Sciences courtyard soil Professor Wang Shiwen pointed out that "long-term consumption of soft water with few minerals is one of the causes of atherosclerosis." The Naval Medical Research Institute provided a clinical response, "Zhoushan island warriors generally felt weak after drinking rainwater for six months." The rainwater was tested for lack of minerals and its water quality was similar to pure water. This is an example of the harm caused to the body in the case of reasonable drinking methods and normal drinking volume, which can say that pure water is a safe food? China's hundreds of millions of adults drink every day with the same amount of pure water (2000 milliliters or so) of tap water, natural water or mineral water, drinking more than ten years, decades have not heard of and did not see a case of harm to the body reports, compared to the regular drinking tap water, natural water and mineral water is safe, often drinking pure water is not safe.

Two, pure water has no nutrition

China Green Food Development Center said: "In addition to safety, high quality, nutrition is also an important feature of green food, green food product standards have a specific embodiment of the requirements of its excellent sensory characteristics, quality quality and nutritional value." In other words, green food not only requires excellent sensory characteristics and quality, but also requires excellent nutritional value. Pure water has no good nutritional value? Can be answered with certainty: no! As we all know, pure water processing, in the removal of pollutants in the water at the same time also removed from the water essential trace elements and macronutrients. Water is an important way for the human body to obtain minerals, under special circumstances or the main source. Tsinghua University, Department of Environment, Professor Wang Zhansheng emphasized: "At the very least, the existing dietary structure of China's residents is relatively homogeneous, and can not be comprehensive and natural supplementation of all kinds of elements, so the nutritional benefits of drinking water still can not be ignored." Professor Li Fuxing, water nutrition expert and director of China Medical Promotion Association Healthy Drinking Water Professional Committee, said, "It has been proved that there are nearly 10 kinds of trace elements in water that are essential to the body. China's current dietary structure, many trace elements are difficult to ingest from food, mainly from water. The absorption rate of calcium in water can reach more than 90%, while the absorption rate of calcium in food is only 30%." Professor Zhu Huigang, head of the National Drinking Water Hygiene Group and a professor at Shanghai Medical University, highlighted, "For drinking water, it is not the purer the better, the inorganic elements in the water are in the form of dissolved ions, which are easy to be absorbed by the organism, so drinking water is an important intake pathway for people to consume minerals. Pure water contains little or no minerals, in the past, mainly used in thermal power plant boilers, electronic industry washing, integrated circuit boards. Drinking pure water should be done with caution, especially for children, the elderly and pregnant women is not suitable." Healthy drinking water proposed by the World Health Organization must meet six conditions, namely: free of harmful substances, contain the right amount of minerals, moderate hardness, rich in oxygen, small water molecule groups, and a weak alkaline pH. Pure water basically does not contain minerals, hardness is close to 0, very little oxygen (distilled water is 0), water molecule group (> 100Hz), pH value of 6.0 or so, is weakly acidic. Canada and Russia's drinking water quality standards stipulate that the hardness shall not be less than 50mg / L (CaCO3), European **** body and the United States drinking water quality standards to maintain the hardness of more than 60. Obviously pure water does not meet the conditions of healthy water, no nutrition, not to mention the excellent nutritional value, how can that be called green food?

Three, long-term consumption of pure water affects health

Water is the most important of the six nutrients on which human survival, minerals and trace elements in the water is essential to human health. Beijing University of Chemical Technology Life Dynamics and Water Resources Research Center Professor Jin Riguang pointed out that: "water for the origin of life and the continuation of life plays a fairly important role in the process, in this sense, we can not say that water is used to quench the thirst of the far-reaching significance of water is to maintain the continuation of human health life." People in the choice of drinking water, should pay more attention to whether it is conducive to health, pure water is conducive to health? National Development and Reform Commission Public Nutrition and Development Center, Dr. Chai Wei in the "2005 China Drinking Water Industry Forum" at the meeting emphasized that "pure water has a strong ability to dissolve minerals, trace elements, people drink large amounts of pure water, the body's original trace elements, nutrients and nutrients, will rapidly dissolve. Nutrients, will be rapidly dissolved in pure water, and then excluded from the body, so that the nutrients in the body out of balance, a health deficit, is not conducive to good health. Many European countries now stipulate that pure water cannot be used directly as drinking water." Martin Fox, M.D., a famous American water expert, emphasized in the book "Healthy Water" that "drinking contaminated water and desalinated water (i.e., pure water) can be harmful to our health." China's Naval Medical Research Institute Water Supply Department Ding Nanhu researcher and others, from 1987 to 1994 on the mice for seven years of testing, so that they drink distilled water for a long period of time, the results found that the mice grow slower, weight loss, osteoporosis, muscle atrophy, pituitary and renal gland system function is destroyed. Dalian, an island garrison, had been drinking homemade distilled water (pure water), over time, officers and soldiers suffered from a variety of mineral deficiency diseases. According to Chen Mengxiong, a senior academician of the Chinese Academy of Sciences, "Long-term consumption of pure water will reduce the body's intake of minerals and beneficial elements. In terms of the relationship to health, natural water is superior to pure water, and mineral water is superior to natural water." A large number of animal tests and clinical responses at home and abroad have proved that long-term consumption of pure water is harmful to health. For this reason, the Shanghai Municipal Education Commission has issued a notice: in principle, since the beginning of the 1997 school year, the primary and secondary schools, kindergartens should no longer use pure water as drinking water for students and young children. The Shanghai Municipal Administration for Industry and Commerce has also issued a notice: advertisements for pure water should not publicize the content of "long-term drinking" and the use of pure water for milk powder, cooking, etc. In March 2003, some primary and secondary school students in Hangzhou bid farewell to pure water, and there are already more than 100,000 primary and secondary school students who have been drinking mineral water. Recently, China Consumers' Association has issued an official warning: teenagers, children and the elderly should not drink pure water for a long time. Green food to health as the basic goal, and long-term consumption of pure water, not only can not play a role in promoting health, but will cause harm to the body, so how can we say 鈥縁 color food?

Since drinking pure water into the market, the drink what water has been the majority of consumers are very concerned about the topic, after several years of intense debate, the conclusion is clear, long-term drinking pure water is not conducive to health, mineral water is the ideal drinking water. National drinking water health team leader, Shanghai Medical and University Professor, doctoral supervisor Zhu Huigang said: "mineral water and general drinking water is different, it contains lithium, strontium, zinc, iodine, selenium, and other trace elements, and some are also rich in macronutrients, so it can replenish the human body needs of the microelements and macronutrients, regulating the body's acid-base balance, these characteristics are general These characteristics are not available in general drinking water. Mineral water is the crown of healthy drinking water." Xu Fang, a senior health expert at the Environmental Institute of the China Medical Control Center, pointed out, "Mineral water is distinguished from ordinary groundwater by the presence of a certain amount of minerals, trace elements or carbon dioxide gas that are beneficial to human health. Since this water is not contaminated by foreign man-made pollution and does not contain calories, it is an ideal health drink for human beings. We have conducted animal tests on more than a dozen kinds of mineral water representative of our country, and found that these mineral waters have different degrees of tumor suppression effect, and some epidemiological survey data also indicate that mineral water does have a great effect on promoting muscle health and prolonging life." In line with the medical mineral water quality standards for drinking natural mineral water on certain diseases have the role of prevention, treatment and alleviation of symptoms.
