The main components of scale (commonly known as "water alkali") are calcium carbonate and magnesium carbonate, and one of the main drugs that doctors give calcium to patients is calcium carbonate. A certain amount of calcium carbonate (magnesium) is allowed in the provisions of China's "Standards for Drinking Water Hygiene".
Calcium and magnesium ions in water are called protective elements of the human body by the medical community, and they can resist the invasion of related elements that damage health. For example, the formation of fluorosis in high-fluorine water sources is related to calcium and magnesium ions. People in areas with less calcium and magnesium ions are prone to fluorosis, while those with more calcium and magnesium ions are less prone to fluorosis. The causes of Keshan disease and Kashin-Beck disease are very complicated, but the lack of calcium and magnesium ions in water is also one of the important reasons. One of the measures to prevent these diseases is to increase the hardness of water (increased calcium and magnesium ion content). There are also many reports at home and abroad: cardiovascular disease patients in soft water areas (less calcium and magnesium ions in water) are significantly higher than those in hard water areas.
At present, many countries in the world have found that drinking water in the tropics is surface water, and the water is relatively soft (less calcium and magnesium ions in the water). Therefore, the growth and development of people in the tropics is relatively short, and the immune system is vulnerable to attack. In areas with relatively high drinking water hardness (more calcium and magnesium ions in water), people are more robust and have stronger immunity to disease. Moreover, if people on the island drink rain for a long time, they will cause muscle atrophy and their immunity will decline.
Scale (water alkali) is an important substance in water. It is a relative value. On the contrary, for people who drink pure water and use RO pure water machine, pure water that does not contain any minerals is very unhealthy water. The absorption and exchange of nutrients by cells requires trace elements and minerals to assist. However, there is no mineral in pure water, and because pure water is the viscous water and acidic water of the macromolecular group, it also takes away the minerals and trace elements of the human body. However, the human body needs minerals and trace elements, so these minerals and trace elements have to be supplemented from food, which will cause the body to eat a lot, the body's metabolism of liquid (water) is much easier than food metabolism. Therefore, people who regularly drink pure water may eventually cause obesity or other chronic diseases. And people eat only three times a day, but the number of drinking water is about 10 times. If too much supplement is pure water, it will destroy the normal physiological balance of the human body itself. After a lot of exercise, drinking pure water can cause water poisoning. In developed countries, the minimum hardness of water is mandatory, and the water must carry minerals (salts).
Even many health experts say that pure water is not as good as tap water. The health of most purified water is indeed not as good as tap water. Of course, in some areas, the pollution of tap water is more serious. Pure water can be used as short-term drinking water. The World Health Organization stipulates that mineral water should be used in disaster relief areas, and pure water is prohibited. Therefore, water with scale (inorganic salt) is harmless. If you feel too much scale, you can use the household mineral water system with ultrafiltration to change the calcium and magnesium compounds into calcium and magnesium ions that are easily absorbed by the human body.
There is also some common sense knowledge, because when I talk to the average person, I usually find people wrong.
Surprising. Many people also call scale "water alkali", so they think that "water alkali" is alkali. But when I told them that "water alkali" is a salt, not a base, they don't believe it. Scale is usually made up of calcium carbonate (CaCo3) and magnesium carbonate (MgCo3), which was learned in middle school chemistry. It is a salt. The acid is a molecule composed of H+ ions, such as HCL (hydrochloric acid) or HCO3 (carbonic acid), and the base is composed of OH- ions such as NaHO (sodium hydroxide) and MgHO (magnesium hydroxide).
So what is the cause of calcified gallstones in the human body? Medical research is that cholesterol causes calcified stones instead of scale. And as the body's cholesterol rises, it causes stones. Some people who sell pure water machines instill in people a very wrong message that scale or "water alkali" causes gallstones or kidney stones, which is a misleading behavior. Usually, even when the water with higher water hardness is opened, most of the salt in the water will be deposited in the container, that is, we usually see the scale in the kettle. There is also a high salt content in the water, which is only 1 to 5% of the salt content in the food. The salt in the food is the culprit that actually causes the rise of human cholesterol. And if people drink low-salt water (pure water) for a long time, the body will take more salt from the food, which is why the chances of drinking pure water instead of gallstones are higher.
