What is Alkaline Drinking Water?

Alkaline water is water with pH> 7. The pH value of ordinary water varies greatly from region to region. Generally speaking, drinking water in cities north of the Yellow River is weakly alkaline (about 7.5).

Water (chemical formula: HO) is an inorganic substance composed of hydrogen and oxygen. It is a colorless and odorless transparent liquid at normal temperature and pressure. The general pH of our commonly used tap water is

The CCTV 3.15 party in 2010 broke the lie that the popular "alkaline water" on the market improves the pH of the human body. Experts in the program pointed out that the ideal living environment for bacteria is alkaline. According to the promotion of alkaline water, drinking alkaline water is more conducive to the reproduction of bacteria.

The following is the actual record of the program:

Li Jiaming: Thank you for your continued attention to the 3.15 party. The bottle of water in my hand can be bought in many supermarkets, but because the three words on its label look different from other drinking water, these three words are "weak alkaline", because of these three The word in the advertisement is another look, saying that it can cure disease, can cure disease and strengthen, and even make you smarter. But have you ever thought that you can really buy this kind of effect at the price of a bottle of water? Let's take a look at what alkaline water is.

In Futian District, Shenzhen, Guangdong, eternal alkaline water is actually sold by degrees. The degree refers to the concentration of calcium ions. A bottle of 100-degree water costs 168 yuan. 100-degree alkaline water has the ability to prevent strokes, calcium supplements, and promote children's growth. .

Can prevent cardiovascular disease, regulate cancer, fight cancer, and develop intelligence. In order to convince people that alkaline water can change the pH of the body, these products have also been demonstrated. If the cells are in an alkaline environment, our cells are lively. Strength appeared in the advertisements by accident. The chairman of the eternal alkaline calcium ionized water experimented with a PH test paper.

The salesperson poured alkaline water into the liquor, and the wine quickly turned blue. Is alkaline water really so magical? Professor Gu of the Department of Chemistry of Capital Normal University told us that most of the water in our northern cities is alkaline water, and the pH test paper also shows that it is blue. There is no such thing as an acid system in medicine. It is just that people will have acidosis when they are sick.

People with normal acid disease have it, and normal lung function can be cleared away quickly. The professor of nutrition food at Peking University told us that in fact, the high school textbook stated that the human environment is very stable, and the external acids and alkalis cannot change the body balance. Human acid and base cannot be easily changed in a sophisticated system. If too much acid becomes acidosis, more alkali becomes alkalosis.

In order to explain the internal environment of the human body, Professor Gu made a simulated buffer solution, and the pH value of the buffer solution did not change at all. The buffer volume before adding is pH 7.4, and it is still pH 7.4 after adding it, which indicates that the human body has a buffering effect, that is, foreign alkali cannot change the pH value of the human body. If you can only affect acid and alkali by drinking alkaline water, it will be poisoning.

The environment that these pathogenic microorganisms like is a little alkaline, and if you drink alkaline water, it will help the harmful substances. The basic function of water is combination. As long as it meets the national drinking water function, it is good water.

Water is H2O, which is all the processes of cell life metabolism. It cannot be separated from water, so you must drink water. The second water is very good for nutrient rotation, or it is a carrier, so all water is a meaning.

Li Jiaming: What is there to explain about water is H2O? Experts hope everyone remembers that all water that meets the national drinking water standard is good water, and it is the same. The statement that alkaline water is good for health is just a marketing method. Can't take it seriously.
