Clean and hygienic mineral water
Traditionally, mineral water is collected from deep underground, rich in mineral salts and trace elements, and is a nutrient needed by human body. However, health experts pointed out that pure water is not suitable for drinking.
Mineral water is also called mineral water. It refers to unpolluted groundwater that gushes from deep underground or is artificially exploited. It comes from deep circulation and has some special physical and chemical characteristics, so it is beneficial to human health and can be used for drinking or medical treatment. Drinking mineral water is characterized by containing a certain concentration of natural mineral salts, trace elements or carbon dioxide gas, which can be directly drunk or used as a water base for preparing beverages.
Because people's physical conditions are different, the types and quantities of trace elements are different, so trace elements and ions in mineral water are not beneficial to everyone. Specifically, the elderly are prone to calcium deficiency due to aging, so they can choose mineral water with higher hardness and delaying aging. Suitable for drinking heavy calcium carbonate mineral water, heavy calcium carbonate magnesium mineral water, metasilicic acid, strontium mineral water and radon-containing mineral water.
Children are in the stage of growth and development, and are prone to calcium and zinc deficiency. They can choose mineral water with higher hardness, such as heavy calcium carbonate mineral water, heavy calcium carbonate magnesium mineral water, strontium metasilicate mineral water, zinc mineral water and iodine mineral water. Pregnant women should drink more magnesium bicarbonate mineral water, strontium metasilicate mineral water, zinc mineral water, lithium mineral water, etc., which is helpful for fetal development and maternal health.
Surface water becomes mineral water after being treated by mineral water equipment, but it is seriously polluted by acid rain and acid snow caused by air pollution, so it is doubtful how much polluted surface water is purified in the process of making mineral water. Because at present, there are only four indicators about pollutants in China's mineral water testing standards. In 1994, the pollutant index of bottled water (including pure water and mineral water) formulated by the FDA of the United States was nearly 50.
In other words, the pollutant index of pure water and mineral water in the United States is the same. Therefore, there is a great possibility that mineral water contains a lot of inorganic minerals and heavy metals harmful to human body. Therefore, whether mineral water is pollution-free depends entirely on the cleanliness of the raw water itself. Only mineral water really taken from deep underground is beneficial to human health.
Friends of health-pure water
Pure water is water that meets the quality standard of drinking water. After being treated by appropriate treatment methods such as ion exchange method and distillation method, it can be directly drunk without adding any additives.
The advantages of pure water purification equipment are: high solubility, the strongest affinity with human cells, and the role of promoting metabolism; It can eliminate greasy in human digestive system, eliminate blood lipid on blood vessels and reduce cholesterol; Drinking pure water can help drugs to be fully dissolved and absorbed, thus improving the curative effect and discharging drug residues in time; It can moisten the skin, is beneficial to beauty, can delay the absorption of ethanol, and has the effect of relieving alcoholism. Make tea with pure water, there will be no tea dirt; Boiling soup and cooking with pure water, its taste is incomparable to tap water; Washing hands with pure water can promote metabolism, and ironing clothes and boiling water will not be bothered by scale.
Some experts pointed out that pure water is drinking water separated and filtered by pure water disinfection equipment. On the one hand, it filters out harmful substances in water, on the other hand, it also filters out minerals and trace elements beneficial to human body. 30% of the calcium needs of children and the elderly come from water. If you drink pure water for a long time, the source of this part of calcium will be gone; In addition, calcium absorption in food is slow, much lower than that in water. Drinking purified water for a long time can not only supplement trace elements such as calcium and zinc, but also absorb minerals in the body and excrete them.
With the improvement of living standards, ultra-pure water, distilled water and space water have entered the homes of ordinary people. Experts believe that drinking pure water for a long time will bring irreversible negative effects on the health of the elderly and children. Young people who grow up drinking pure water may feel weak all over, or suffer from cardiovascular and other senile diseases in advance. Therefore, experts remind: beware of falling into the misunderstanding of drinking pure water.
Dr. Gao from Jilin Provincial Hospital of Integrated Traditional Chinese and Western Medicine said that the purified water on the market is mainly purified by distillation and reverse osmosis technology. These technologies were originally used in industry, and some elements beneficial to human body were removed. Such as magnesium, zinc, iron, iodine and other minerals and inorganic salts. Healthy drinking water must contain certain minerals. Drinking water is one of the main sources of 10 trace elements needed by human body. Therefore, people who drink pure water for a long time must adjust their food structure, but some trace elements are difficult to obtain from food.
Electrolytic water can't scavenge free radicals.
Electrolyzed water deliberately prevents ion exchange when water is electrolyzed, so that the pH value of water changes, thus producing so-called acidic water or alkaline water. Some people think that drinking acidic electrolyzed water or alkaline water can adjust the pH of the human body, but this is wrong, because the human body will automatically maintain the acid-base balance, and food will not change the acid-base concentration in the blood; So is drinking water, of course.
Can electrolytic water scavenge free radicals? Although the free radicals in water may be destroyed during electrolysis, there are not many free radicals in ordinary drinking water, so there is no need to make water without free radicals.
In addition, it is even more debatable to say that drinking electrolyzed water is enough to eliminate all free radicals produced in the process of human metabolism. Because to really prevent free radicals from harming normal cells, it is necessary to rely on antioxidant enzymes and vitamins in the body to play a role between cells; Although some experiments have found that if electrolyzed water is injected into the blood in the test tube, free radicals will indeed disappear, but whether the results of the test tube experiment can also play a role in the human body is still lacking scientific evidence.
Mineral water-supplement minerals needed by human body
Natural water contains many minerals and trace elements needed by human body, but it has the same problem as concentrated mineralized solution, that is, it is impossible to confirm that all trace elements are beneficial to human body.
It is also impossible to completely remove harmful pollutants. The water source must be strictly protected and needs long-distance transportation, so safe and affordable mineral water has become the first choice for consumers.
The slogan of "more and healthier" not only makes ordinary consumers know about mineral water, a new bottled drinking water, but also makes the mineral water brand represented by Master Kong stand out in the fierce bottled water market.
Drinking raw water with high hygienic standards directly will not lose calcium, but if you drink raw water with diarrhea, it is still not suitable for drinking directly. The country should try to make more and more people drink tap water that meets the hygienic standard, and everyone should also pay attention to choosing direct drinking water with higher hygienic standard.
According to the physical condition and the difference of drinking water in different areas, choosing suitable mineral water to drink can supplement minerals, especially trace elements. What water to drink in midsummer is a big problem to supplement the minerals lost by sweating.
