The ideal drinking water beneficial to human health must meet seven standards:
These seven criteria are:
1, which does not contain any toxic, harmful or odorous substances;
2. The hardness of water is between 30 and 200 (calculated by calcium carbonate);
3. The mineral content needed by human body is moderate;
4. The 4.PH value is weakly alkaline (7-8);
5. The content of dissolved oxygen and carbon dioxide in water is moderate;
6. The water mass is small; The best drinking water is hexagonal water (water with six molecular groups).
7. Water has powerful nutritional and physiological functions.
Two of them are essential, with moderate mineral content and weak alkaline PH value. Therefore, it can be said that healthy water should meet the above seven standards, or at least drinking water with moderate mineral content and weak PH value required by human body.
The following are detailed standards formulated by the World Health Organization, which are summarized as follows:
1. does not contain any substances that are toxic, harmful and have peculiar smell to human body.
2. The hardness of water is between 30 and 200 (calculated by calcium carbonate).
3. The mineral content needed by human body is moderate.
4. Number four. The PH value is weakly alkaline 7-8.
5. Dissolved oxygen in water is not less than 7 ml per liter, and carbon dioxide is moderate.
6. The half-width of water clusters is less than 100 Hz (energetic small molecular water).
7. The medium nutritional physiological functions of water (solubility, permeability, diffusivity, metabolism, emulsification, cleaning power, etc.). ).
Healthy water with six small molecular groups has a beautiful hexagonal structure and snowflake-like crystals.
