Water only pure is not enough, pure water is not equal to healthy water, healthy water conditions are many.
At the beginning of the large-scale listing of pure water, expert opinion on each end, some people believe that the human body needs more than ten kinds of trace elements intake from
water, air and food, some of these elements are only present in the water, such as selenium, once the lack of people are susceptible to myocarditis. If long-term drinking
with pure water means giving up should be obtained from the water part of the human body needs trace elements, and even a large number of the loss of the body's original mineral
quality, over time will feel weak or early cardiovascular diseases of the elderly. Some experts believe that long-term consumption of contaminated water
will have a negative impact on the human body. Although city tap water has been sterilized, but it is difficult to avoid secondary pollution, long-term drinking is bound to have
harm. Although pure water contains no or few trace elements, and does not harm human health. So, what is the concept of healthy drinking water?
With the development of drinking water science, experts in many countries more and more recognized by Dr. Martin of the United States on the world's scientific research report on drinking water and health
analysis, he believes that healthy drinking water should be: water quality is not polluted, PH value is greater than 7.0 slightly alkaline, hardness of 170 milligrams per liter,
Total dissolved solids in the water about 300 milligrams per liter. PH value refers to the acidity and alkalinity, hardness refers to the total amount of calcium and magnesium, total dissolved solids is
used to measure all the minerals in the drinking water,
including not only calcium and magnesium, but also zinc, copper, selenium and so on. The right amount of hardness and total dissolved solids in the water are two beneficial factors,
both of which have been linked to lower mortality from cardiovascular disease.
Professor of the IDM Institute of Biotechnology in Beijing put forward seven criteria for healthy water: no toxic, harmful and odoriferous substances; moderate hardness
moderate; moderate content of minerals needed by the human body; slightly alkaline pH; moderate content of dissolved oxygen and carbon dioxide in the water; small molecular clusters in the water; and strong physiological function of the water.
Water has a strong physiological function, he said. He believes that modern people should not only focus on the purity of water and ignore the physiological role of water.
Water only pure is not enough, pure water is not equal to healthy water.
Experts caution: pure water is suitable as a supplement to drinking water, not suitable for long-term drinking, especially for children in the process of growth and development.
Professor Jin Riguang said, pure water, space water, ultra-pure water is essentially pure water, pure water and human traditional drinking water has the principle of the difference
difference, its advantage lies in the absence of bacteria, no viruses, clean and sanitary, but pure water water molecules are extremely tandem condensation of water molecules like twine
long chain, the human body's traditional drinking water habits caused by the human body of this form of The human body's traditional drinking habits cause the human body to this form of unfamiliar, not easy to pass through the cell membrane, will lead to the body's beneficial life
relevant elements of the loss of the body, a large number of drinking will be drenched away the body's useful trace elements, thereby reducing the human immune system, prone to disease
. A large number of scientific studies at home and abroad found that: long-term consumption of water containing fluoride is too low, the rate of dental caries in children in the region increased; long-term consumption of water containing iodine
too low, will cause the human body goiter, visible trace elements on the human body is important. Some sensitive people feel that the more they drink pure water, the more they drink
Not thirst quenching, drink a long time to feel weak. Therefore, the pure water as a living water for the growth and development of young people have
more prominent side effects, is not conducive to the vital activities of the body organs.
Some people believe that the trace elements needed by the human body can be taken from food, and that water only needs to be sterile. Prof. Jin believes that this statement is not scientific
Scientific
Research shows that every 50 years, plants contain trace elements will be reduced by 30% -60%, that is to say, vegetables now contain
there are trace elements than 50 years ago to be a lot less, so drink more water containing more minerals is still very necessary for the human body. . Some manufacturers began
to produce ecological water, adding more than a dozen kinds of power elements and more than 20 kinds of life elements in pure water, so that it contains strontium, zinc and other trace
elements that are beneficial to the human body.
For areas where the water quality is not ideal, people should pay attention to the protection of drinking water sources, improve the water quality treatment process in water plants, and strengthen the deep treatment of water
Treatment. Scientific selection of water purifiers, every five or six months, to achieve effective water purification, the user should be timely replacement of the cartridge, never pay attention, do not let the children
children only drink pure water.
