Water is the source of life. Now there is a saying that weak alkaline water is more beneficial to health. In the end, can the PH value of drinking water really affect the pH value of body fluids, or is it the gimmick and hype of merchants?
Everyone knows that the PH value of the water we usually drink is between 6 and 8. In other words, the concentration of hydrogen ions is between tens of thousands and millions of times that of gastric acid. As we all know, our stomach is a strong acid environment. When the water reaches the stomach, there is no suspense, and it will turn into acid without exception; That's the point! ! ! ! Therefore, the subtle differences in the pH of the water we drink are meaningless in front of powerful human machines.
? "The closer the pH value of drinking water is to the human body's pH value (7.35-7.45), the better. A healthy life needs natural weak alkaline water. " The propaganda language of these businesses seems to be "scientific", but it is actually only the propaganda means of businesses or enterprises, misleading and deceiving consumers, rather than the result of scientific experiments.
We usually say that the pH value of human body is 7.35-7.45, which refers to the pH value in human blood, but cannot be understood as the pH value of human body. The human body is a very precise system, which completely relies on its own regulating function to realize the dynamic balance of acid and alkali in the body. And this balance will not be easily changed by substances ingested by the outside world. And drinking water won't change it.
Wang Tao, director of the Department of Nephrology, Peking University Third Hospital, Peking University Changjiang scholar, professor and doctoral supervisor, said that there is no such thing as acidic constitution in medicine. Some diseases, especially chronic diseases, may form more acidic waste accumulation in the body for a long time, but it is not the accumulation of acidic waste that causes diseases, and this causal relationship is irreversible. Even if the body is easily turned alkaline by the water ingested by the outside world, it is harmful to the human body.
Because there is no evidence that pH has a direct impact on human health, the new national standard for drinking natural mineral water, which was implemented on June 65438+1 October1day, 2009, no longer requires mandatory labeling of pH, so as to avoid unscrupulous manufacturers using it for speculation and deliberately misleading consumers. A person in charge of the National Food Quality Supervision and Inspection Center once said, "As long as it is within the scope allowed by the state, the pH value has no specific meaning."
The biggest function of water is combination, which is the transportation of human nutrients and the excretion of waste, and it is an important carrier or participating substance of cell life metabolism. Water is just H2O. As suggested by experts, anything that meets the national drinking water standards is good water and can be safely drunk. There is no saying that acidic water is harmful to human body and alkaline water is beneficial to human body. The statement that alkaline water or weakly alkaline water is good for health is only a marketing tool, so consumers should not take it seriously.
