Original title: Drinking pure water makes people acidic? Lack of sufficient scientific
drinking pure water makes people acidic?
recently, there is a saying that long-term consumption of pure water will lead to more and more acid body fluids. It can also cause calcium loss, muscle weakness and cartilage.
In fact, the human body simply does not have acidic and alkaline physique, because the human body itself has a strong acid-base regulation function, the external impact on it is very small, even if the intake of acidic or alkaline substances, will be this regulation function quickly neutral. For example, our stomach fluid pH is about 2, even if drinking so-called weak alkaline water, to the stomach will be completely acidified. Then to the intestines, no matter what the nature of the water, will become alkaline.
normal pH of human body fluids is between 7.35 and 7.45, although the body is constantly producing and ingesting acid and alkalis, but the pH of body fluids does not change significantly. This is because, on the one hand, the body fluid is a buffer system, the pH value is less affected by the outside world, on the other hand, the regulation of the lungs and kidneys will reduce significant changes in PH value. Therefore, long-term consumption of pure water does not make us acidic.
as for the body's main intake of nutrients, nutritionists say it is diet, and the role of water is very small. Human nutrition loss, and natural conditions, age, exercise, physical fitness, etc. , the main role of water in the human body is to promote human metabolism, rather than to provide nutrition to the human body, not to cause the loss of nutrition.
, the concentration of ions in human body fluids is relatively balanced, and calcium ions are no exception. The main cause of calcium deficiency is insufficient dietary calcium intake, but also with hormone levels, vitamin D levels, sunlight, exercise, etc. , but nothing to do with what water to drink. At present, there is no scientific evidence that pure water will lead to the loss of calcium in the human body, "drinking pure water is harmful to health" is not sufficient scientific basis.
