[Hongjie Water] Tell me about your misunderstandings about scale over the years

Scale, scientific name "calcium carbonate/magnesium carbonate". It originates from the water of rivers and lakes in nature, and whenever water containing calcium or magnesium ions is boiled, scale is formed. The main components of scale are calcium carbonate and magnesium carbonate. In the provisions of China's "Sanitary Standards for Drinking Water", a certain amount of calcium carbonate (magnesium) is allowed, which does not exceed 450 milligrams per liter (calculated as calcium carbonate). The value specified in the "Drinking Water Quality Standard" is 300 milligrams per liter (calculated as calcium carbonate).

Everyone feels very disgusted when they see scale, mistaking it for having a negative impact on their health. Actually, scale is harmless. Calcium and magnesium, as minerals, have certain benefits for our bodies. For example, mineral water also contains certain amounts of calcium and magnesium. Some of the calcium and magnesium ions we drink into the body will be excreted from the body with urine, and some will combine with enzymes and proteins in the body to produce calcium containing proteins, which are beneficial for our bone growth and strong teeth.

The presence of scale in water indicates that the water quality is relatively hard, indicating that it is natural water, containing mineral nutrients, and indicating that it is alkaline water. If there is no appearance of scale, it indicates that it is highly likely to be pure water, acidic water, and "bone scraping water" that will take away bone calcium and blood calcium from the human body. So, for water with a hardness within the national range, there is no need to specifically remove calcium and magnesium ions. On the contrary, for people who drink pure water for a long time or use a pure water machine, pure water that does not contain any minerals is very unhealthy.

Is drinking water with scale harmful to the stomach? Experiments have shown that even when scale enters people's stomachs as a solid deposit, it is decomposed into calcium and magnesium particles under the action of gastric acid. So, as long as it meets national standards, even if the boiled water has some scale, it can be safely consumed. It has nothing to do with stone disease. The generation of scale is a physical phenomenon after water boils, while stone disease is a physiological phenomenon in the human body.

Some water contains minerals, so the phenomenon of calcium carbonate crystallization occurs after heating, just like bottled mineral water is labeled with "white precipitation is a normal phenomenon".
