Experts say water purification equipment "functional water" is not beneficial to health is not reliable

Can the water purifier produce these functional water? Is there a "

These water purification equipment are mainly a concept: the product has the function of preparing weak alkaline water. Manufacturers claim that weak alkaline water is the most in line with the needs of the human body of healthy water, nutrition and health care, not only to promote human development, but also to prevent the occurrence of some chronic diseases.it better for your health to use weak alkaline water? Zhao Feihong, head of the Beijing Association for the Protection of Healthy Drinking Water, said there was no evidence that the
pH
of water was related to health. Experts said that China's drinking water indicators do have a
pH
value, the range is
6.5-8.5
, but this is not a health indicator, but mainly to prevent metal pipes by
pH
low liquid corrosion considerations.small molecules of water, mostly dependent on alkaline water machines exist, merchants claim that such a form of water is easier to absorb. Experts say some water, such as mineral water, does have smaller molecular groups, but there is no evidence that it is directly related to health, let alone cures.In order to prove that

weak alkaline water, small molecular group water is beneficial to health
"
, some businesses said,
"
The World Health Organization proposed high-quality healthy drinking water standards pointed out that high-quality healthy water should be
pH
value is weak alkaline;but the reporter consulted the data found that the current general World Health Organization drinking water standards, the third edition of a total of five test indicators. The only reference to the
pH
value is the fifth item, chapterinorderable partarticle
10
, the standard is the same as china's current standards, for
6.5-8.5
, the reason is expressed as: low
pH
value of water has a certain corrosive, and high
pH
value of water will have a slippery and odor. The World Health Organization Drinking Water Standards do not mention the concept of

can cure diseases?"Response" experts said that never heard of water can cure diseases, wading products should not promote the efficacy in addition to alkaline water machines, household soft water machines, magnetized water purifiers, household ozone water machines are also best-selling products. Soft water machine claims
"
soft water oxygen content is high, low hardness, can prevent stone disease, reduce the burden of heart and kidney, and beauty effect

; Odor, hand washing smooth
"
, ozone water machine is said to be
"
to increase the oxygen content of the water, water becomes active water, not only solubility, permeability, but also activate aging cells, accelerate metabolism, thereby improving human immunity
"
.In addition to weak alkaline water, magnetized water, ozone water, there are
"
household multi-functional water machine manufacturers claim that its prepared

function water
"
can treat a variety of diseases, such as diabetes, hypertension, gout, liver disease, migraines, physiological diseases, back pain, stones, and even anti-cancer. the function of Shenshui have such a big effect? "I
't heard of anything like this, and I think it's unlikely."
,"
Xuemei, vice chairman of the Diabetes Professional Committee of the Chinese Association for the Integration of Chinese and Western Medicine, said. Jian, chief physician of cardiology at the Hospital for Cardiovascular Diseases outside the Chinese Academy of Medical Sciences, believes that the notion that shot water can cure diseases is highly unscientific and unconscionable.
"
water is mainly composed of hydrogen and oxygen, no matter what treatment can not have a special effect, unless other substances are added. And after adding other substances, it is not simply water, should not drink, how to drink all have to vary from person to person.
” Zhao Feihong stressed that even if some water machines can play a role in resifying water molecules and enhancing solubility, but there are no tests to prove its effect. , some products under the banner of new foreign technology are even more outrageous. For example, a

aquatic water from Japan said that its

for diabetes, allergies, hypertension, skin diseases, respiratory diseases, digestive diseases, neurological diseases, AIDS, cancer, and various viruses have a very good effect.
” Reporters in Japan found that
"
water"
"
in the local dispute, not the mainstream of water purification products. Water purifiers sold in Japan are mainly sterilization and filtration, and all products can be sold as health-aided goods, but not as

Sothe water
"
. If manufacturers say that this water can treat diseases, it is exaggerated propaganda, will be punished. "
water is also controversial internationally, and even Japan, the origin of the concept of functional water, has focused only its research on electrolyte water. In China, functional water is an unac approved concept, electrolyte water is independent of functional water
'
, its preparation equipment is
'
health care equipment
'
, to be approved by the State Food and Drug Administration.
"
Zhao Feihong said. reporters in the State Drug Administration website query found that a very small number of approved water machines are defined as

electrolytic water generation device
"
, its functional note is:
"
to generate strong acidic electrolytic water with disinfection and sterilization effect, can be supplied to the medical and health institutions in various departments
"
. Wei Todong, head of the emergency center of the Beijing Municipal Health Supervision Institute, told reporters that a variety of water-making machines, including water purifiers, are wading products and are managed by health supervision departments at or above the provincial level. It is understood that the National Health and Family Planning Commission formulated in
2013

water is harmful to your health? : Calcium and magnesium and other metal cations are not pollutants, scale does not affect health Zhao Feihong believes that should not blindly pursue the reduction of calcium, magnesium and other metal cation concentrations, they are not pollutants, the formation of scale does not affect health. the current National Drinking Water Standards stipulate that tap water hardness should not exceed
450
mg
/
liters; However, Zhao Feihong reminded that
6
months of infant kidney development is not complete, may consider using water purification equipment to reduce water quality hardness. kind of water is healthy water? Experts say tap water is sufficient for the average household, and water purification equipment is recommended in areas with more pollution or downstream rivers. a wide variety of water purification equipment on the market, which effect is good? Wu Zhigang, a professor at Tongji School of Medicine at Huahua University of Science and Technology, believes that ultrafiltration is not as good as reverse osmosis when compared with water purification effects. Zhao Feihong also said that people living in the lower reaches of the river to reverse osmosis water purifier as a good, can more effectively filter out impurities, organic matter and pesticide residues. Zhao Feihong specifically reminded that ozone water machine to be used with caution, because ozone is a strong oxide, long-term drinking of this water may cause damage to the oral cavity and gastrointestinal mucosa.
