What is good and healthy water? Take a look

　　Traditional nutrition confirms that humans need seven nutrients: water, carbohydrates, lipids, proteins, vitamins, minerals, and dietary fiber. Among them, water is the first of the seven nutrients that sustain life. It is not only a nutrient necessary for maintaining life, but also a carrier of other nutrients.

　　Water acts as a medium for structural nutrients, regulating nutrients, and a carrier for metabolites in the human body's metabolism, maintaining the "navigation" of nutrients required for life on their respective metabolic pathways. Without water, all other nutrients are like dried mud and sand on a dry riverbed. Therefore, water is one of the most necessary and important nutrients for humans, which is a conclusion in medicine and nutrition.

　　Zhao Lin, the chief health education expert of the Central Civilization Office and the Ministry of Health, said earnestly in an interview with CCTV: "Don't ever forget that water is the most important nutrition. So children should drink more water. Only by drinking good water can they detoxify and promote metabolism."

　　Healthy and safe water can enhance the body's immune ability and promote cell metabolism. The diseased cells in the body will lose the conditions for malignant transformation and toxin diffusion, and the chance of getting sick will naturally decrease; therefore, while paying attention to seeking medical treatment, we must replenish the body with healthy water and strive to create a healthy living environment for cells. So, cherish your health and pay attention to healthy drinking water first! However, many people do not know what healthy water is and are at a loss about what water to drink. Now, according to the works of Dr. Martin Fox, a famous American healthy drinking water expert, "Healthy Water", Dr. Batman of the United States, "Water is the Best Medicine", "Drinking Water Like This Can Cure Diseases", Dr. Lin Xiuguang of Japan, "Death by Water", and other works, as well as relevant national standards, it is concluded that good water is the first choice of natural water.

　　Natural water includes both surface water and groundwater. Natural mineral water, based on its water quality, belongs to natural water.

　　What is natural mineral water?
　　1. Natural mineral water is natural groundwater.
　　2. Natural mineral water is highly safe and pollution-free.
　　3. Natural mineral water is small in quantity and high in quality.
　　4. The method to distinguish natural mineral water is the types of minerals and trace elements in the water.
　　The limit index of natural mineral water is an important parameter for judgment. One (or more than one) of the eight indicators in the table must meet the requirements.

　　Can all natural mineral water be drunk?
　　All natural mineral waters are drinkable, the key is how much to drink.
　　The natural mineral water produced in my country is mainly metasilicic acid type and strontium type.
　　For example, selenium is an essential trace element for the human body.
　　Selenium deficiency will reduce immunity and increase the incidence of cancer.
　　But excessive intake of selenium will cause selenium poisoning.
　　Selenium-containing water must be marked with the natural mineral water logo on the bottle, provided that the selenium ion content exceeds 0.01mg/L. 　　However, the World Health Organization's drinking water quality guidelines and China's tap water standards both stipulate that the selenium ion content in water should be less than 0.01mg/L.

　　Why is it different?
　　The main reason is that the standards are different. The standard for tap water is that an adult weighing 60 kg drinks 2L a day, which is safe for 70 years. The standard for natural mineral water is that an adult weighing 60 kg drinks 0.5L a day, which is safe for 70 years.

　　Natural water (surface water~shallow groundwater, mountain spring water, river water, lake water, etc.)
　　Most tap water is natural water. Be sure to boil it before drinking! Boiled tap water is stronger than purified water. However, boiled water can only kill viruses and bacteria, but is ineffective against stubborn organic pollutants and heavy metal pollutants. Therefore, when choosing long-term drinking water, purify the water first, and then decide whether to boil it.

　　The lower the TDS concentration, the better!
　　What is TDS?
　　TDS refers to the total amount of dissolved components in water, including the total amount of various ions, molecules, and compounds dissolved in water. It is the abbreviation of total dissolved solids.
　　Our country's drinking water standard GB5749 stipulates 106 indicators. Note that there are no beneficial indicators in these 106 indicators. They are all limited indicators, which are related to the WHO drinking water quality guidelines. These 106 indicators comprehensively evaluate water quality. It is very unscientific to evaluate water quality only by TDS.
　　Note: TDS test sticks can only detect conductive substances in water, and cannot detect bacteria and viruses.
　　After 30 years of research, Dr. Martin Fox (PH, D) of the United States proposed that the standard for healthy water is: containing a certain amount of hardness (the sum of calcium and magnesium ions in water), ideally about 170mg/L; containing a certain amount of total dissolved solids (the sum of minerals in water), ideally about 300mg/L; pH value (above 7.0).

　　Purified water is not recommended for long-term drinking
　　Purified water is pure water produced by manufacturers through reverse osmosis equipment. Pure water contains almost no minerals and trace elements.
　　Whether the water contains minerals is significant in that natural water or natural mineral water rich in minerals can avoid the health risks brought by low-mineral water or pure water.
　　In summary, natural mineral water that is rich in minerals and meets drinking standards is better than natural water, and natural water is better than purified water.
