1, on the definition of WHO healthy water.
There are many definitions of healthy water on the Internet, most of which are rumors about the definition of healthy water by the World Health Organization (WHO). So far, we haven't seen an exact source from WHO's explanation. However, in the book Nutrients in Drinking Water published by the World Health Organization, more than 80 studies have been conducted in the past 50 years, and it is concluded that drinking hard water, that is, water containing calcium and magnesium ions, may reduce cardiovascular and cerebrovascular diseases, especially magnesium ions. This scientific conclusion directly proves that pure water without calcium and magnesium ions is dangerous to human health; "... removing minerals from water may have certain health risks"; In Martin Fox's Healthy Water, it is stated that after 30 years of research, we still get Schroeder's initial conclusion that drinking soft water is easier to get cardiovascular diseases than drinking hard water.
The above two discussions show that healthy water must contain a certain amount of calcium and magnesium ions and other beneficial minerals, and pure water is definitely not healthy water.
2. The concept of healthy water put forward by Professor Li Fuxing and others.
Professor Li Fuxing is a famous water nutrition expert in China. 1994 puts forward seven standards of healthy water (water and nutrition, the source of life, published by Beijing Normal University Press in July 2007, P2 10);
Does not contain toxic, harmful or odorous substances;
The hardness of water (calculated by CaCO _ 3) is moderate (30-200mg/L);
The mineral content required by human body is moderate (including calcium content ≥ 8 mg/L);
The pH value is neutral or slightly alkaline;
The content of dissolved oxygen and carbon dioxide in water is moderate (dissolved oxygen in water ≥6mg/L, carbon dioxide10-30 mg/L);
The water mass is small, and the half width is ≤ 100Hz (one of the indicators of water activity);
Water has strong physiological functions (permeability, solubility, metabolism, etc.). ).
3. Dr. Batman's discussion on healthy water.
Batman is a famous doctor of medicine in water research in America. He published three books about how to drink water and treat diseases, such as Water is the Best Medicine, Drinking Water in this way can cure diseases, and Water is the Best Medicine III. These books sell well all over the world. In these three books, he described in detail how water cures diseases from the medical and cytological principles. Treat depression, obesity, cancer, etc. He described in detail the "key role of minerals" in "Water is the best medicine III", and elaborated the role of minerals in water, such as potassium, calcium, magnesium, zinc, selenium, molybdenum, copper, manganese, strontium, vanadium and silicon.
4. Is mineral water healthy?
With the improvement of people's living standards, people began to change from eating well to eating healthily, and then people paid more and more attention to the health of food and drinking water. It is generally believed that mineral water, especially high-quality mineral water, such as glacier water and mineral water in Changshou area, should be healthy water. If they are not healthy water, what water can be defined as healthy water? Some experts introduced the "Alashan" strange spring, the water in Changshou village and the glacier spring. The facts and examples of countless people's longevity prove that high-quality mineral water is not only healthy water, but also can make people live longer.
1) is nontoxic, sterile, harmless, colorless and tasteless, and harmless to human body;
2) The pH value of general mineral water is ≥7.0-7.8, which is weakly alkaline;
3) The water mass of mineral water is small, and the half width is ≤ 100Hz (one of the indicators of water activity).
4) minerals and trace elements beneficial to human body.
Conclusion: The definition and characteristics of healthy water are given.
After summarizing the above definition standards of healthy water, we give the definition of healthy water: healthy water refers to water that is harmless to human body, can improve and enhance human physiological efficacy, enhance human health and improve the quality of life on the basis of satisfying human basic physiological functions and life maintenance. We think it is impossible to generalize the various quantitative indicators of healthy water. Different mineral content, activity, permeability, oxygen content and pH value have different beneficial effects on human body in different water, just as different pharmaceutical ingredients form different drugs, there is no panacea in the world, so there is no water in the world that can improve all physiological functions and health care functions of human body. For another example, there are many kinds of healthy food, as long as there are no toxic and harmful ingredients that are harmful to the human body and help the human body to produce some physiological functions, it is healthy food, so there are many kinds of healthy food, and their functions and functions are also different. By analogy, as long as a certain kind of water can meet the basic physiological functions of human body and the needs of life maintenance, it is harmless to human body for a long time, and can improve and enhance some physiological functions of human body and enhance human health, such water is healthy water.
From the above analysis, we can draw a conclusion that healthy water is a collective concept, not a single concept, that is to say, there are many different types of healthy water in healthy water, and each kind of healthy water has different functions in improving and enhancing human physiological efficacy; At the same time, we can also understand that as long as a kind of water is suitable for long-term drinking, harmless to human body, can improve and enhance some physiological effects of human body and enhance human health, it is a kind of healthy water. There is no need to force it, and a healthy water cannot improve and enhance all the physiological functions of the human body. The so-called "all-round" healthy water does not exist.
Summarizing the connotations of five concepts of healthy water, we can conclude that healthy water has the following characteristics:
1) is non-toxic, sterile, harmless, colorless and tasteless, suitable for long-term drinking and harmless to human body;
2) contains some minerals (medium) or trace elements;
3) Strong activity, half width ≤ 100Hz.
So we should drink more safe water, which is good for our health. Healthy water is also safe water! ! ! ! !
