I believe that friends who will search this question must face the following situations:
1, the elderly at home want to buy two or three thousand hydrogen-rich water cups and two or three thousand hydrogen-rich water dispensers. What if I can't convince them?
2. Is it effective for a friend to send a hydrogen-rich water cup? Use it when you have it.
I always hear about it on the internet. What is this? Should I buy it? How to buy?
Since the whirlwind of Japanese hydrogen-rich water cup was blown to China, with the continuous occurrence of hydrogen-rich water legendary events, there are more and more domestic hydrogen-rich water products.
Many people have benefited, but many people will still ask, is the hydrogen-rich water cup true or false? First, let's learn about hydrogen medicine.
To answer "Is hydrogen-rich water a scam?" First of all, we must understand the source, function basis and health preservation principle of hydrogen-rich water.
The concept of hydrogen-rich water actually originated from plain water in Japan, that is, hydrogen-containing water in Japan. As soon as this concept spread to China, it was naturally called hydrogen-rich water.
In 2007, Professor Naruto Ota of Japan Medical University published a paper "Oxygen Free Radical Antioxidant Therapy for Decreasing Cytotoxicity through Hydrogen Selectivity" in the world-famous journal Nature Medicine. It is found that hydrogen molecules can scavenge human free radicals and have a good therapeutic effect on aging and various chronic diseases caused by free radicals.
I learned from Shaanxi Science and Technology News: Is healthy "hydrogen" so heavy? If this paper by Professor Naruto Ota of Japan Medical University in 2007 is false, then hydrogen-rich water is a scam, otherwise it is true.
Because hydrogen molecule is the smallest molecule in the world, although its solubility in water is not high, its permeability is very strong.
That is to say, although the solubility of hydrogen is low, there are a lot of hydrogen molecules in hydrogen-rich water. By drinking water rich in hydrogen, hydrogen molecules can be quickly absorbed by the human body, and even hydrogen molecules can directly enter the nucleus.
In fact, since its publication, this article has attracted great attention from international academic circles and has been quoted more than 500 times.
Many scholars in Japan, China, the United States and other countries have conducted extensive research on the evaluation of therapeutic effects of various diseases such as breathing hydrogen, drinking hydrogen water and injecting hydrogen brine. Animal models and clinical studies have proved that hydrogen has an auxiliary therapeutic effect on various diseases and injuries, and a new field of hydrogen medicine has been established.
According to incomplete statistics, there are more than a thousand scholars engaged in hydrogen medical research in China.
Nearly 10 academicians of the two academies participated in hydrogen medical research, including Hou Yunde, Zhong Nanshan and Wang, as well as scientists such as Professor Sun from the Second Military Medical University, Professor Xu Kecheng from Guangzhou Cancer Hospital General Hospital, Professor Yao Dingshan from Shanghai Institute of Technical Physics of Chinese Academy of Sciences and Professor Liu Jian from Jiaotong University.
After 20 13, there were more than 80 national natural science foundation projects related to hydrogen medicine in China, and representative academic institutions were established one after another:
Many laboratories of Naval Medical University 10 have carried out research on the treatment of many important diseases with hydrogen physiological saline;
The Hydrogen Science Research Center of Shanghai Jiaotong University conducts research related to medicine and agriculture;
Research Center of Hydrogen Medicine, School of Life Sciences, Beijing University of Technology conducts research on tumor and wound repair;
Research on medical hydrogen biomaterials in Shenzhen University Medical College;
Nanjing Agricultural University conducts various research on hydrogen agricultural biotechnology;
Huashan Hospital of Fudan University has carried out clinical research on the treatment of skin diseases with hydrogen water.
School of Life Science and Technology of Xi Jiaotong University is engaged in the study of mitochondrial effect of solid hydrogen.
20 17-2020 The National Natural Science Foundation supported 28 hydrogen medical research projects.
At present, more than 2,000 papers in this field have been published internationally, nearly half of which are from China, and 10 many hydrogen medical research centers and trade associations have been established one after another. For example:
Shanghai Wellcome and Medical Research Center
China Senior Health Care Medical Research Association Hydrogen Molecular Biomedical Branch
China-Japan Medical Science and Technology Exchange Association Hydrogen Molecular Biomedical Professional Committee

Wuxi nutrition health care association hydrogen medicine professional Committee
Guangdong province senior health care association hydrogen medicine professional Committee
Hebei province health service industry association hydrogen medicine branch
China health care association hydrogen and health professional Committee
Institute of hydrogen medicine
Yangtze river delta hydrogen energy healthy development research institute
Professor Sun said in an interview with the media:
"From a social point of view, I dare not say that its discovery can be compared with the historical position of penicillin in that year, because penicillin can be immediate and the medicine can get rid of the disease. The role of hydrogen molecules is more to regulate, prevent and alleviate, and it is not excluded that a few patients can achieve the goal of radical cure only with hydrogen water.
Therefore, its future prospects are more inclined to chronic diseases that are difficult to cure, delay aging and promote health, but this is significant enough, and it will affect the whole medical field. "
Then, if hydrogen-rich water is deceptive, why are there so many experts and scholars studying it?
So, in the face of a wide variety of hydrogen-rich water cups, how should we choose? How to buy a hydrogen-rich water cup is the most reliable? Water and hydrogen remind everyone to remember one sentence: no pains, no gains.
How to choose a hydrogen-rich water cup?
The strategy is as follows
For Xiaobai, a hydrogen-rich water cup, he wants to buy a water cup, but in the face of various hydrogen water cup products on the market, he is often at a loss and doesn't know how to choose.
Today, I will share some knowledge about the hydrogen-rich water cups on the market. I suggest you read the hydrogen-rich water cup before buying it to avoid being cheated!
First, the hydrogen-rich water is good, which does not mean that the hydrogen-rich water cup is good!
Many people buy hydrogen cups, which naturally take a fancy to the healthy conditioning effect of hydrogen molecules in hydrogen-rich water prepared by hydrogen cups.
You can't just look at the "face value" of a cup with a sense of technology or a cup!
I want to tell people who want to buy hydrogen-rich water cups that they must remember this sentence: hydrogen-rich water is good, but hydrogen-rich water cups are not necessarily good.
Regardless of the concentration of hydrogen and water prepared by water cups, water quality safety is very important.
After all, even the best hydrogen water contains non-hydrogen derivatives such as ozone and hypochlorite, as well as the precipitation of heavy metals. Dare you drink?
Most cheap hydrogen-rich water cups on the market are based on carrier electrolysis, and even more, two stainless steel sheets are directly used as anode and cathode. The product will be completely oxidized after the anode is not used for many times, which will not only make hydrogen, but also pollute the water source and bring health risks to human body.
The biggest feature of this kind of cups is that the bubbles are smoky or milky. Because the electrolysis efficiency is low and large bubbles are produced, it looks white, and some have unpleasant smell.
This kind of cup usually has a low hydrogen concentration. Many consumers who only know that hydrogen-rich water is good blindly and impulsively go online to find hydrogen-rich water cups. They are also complacent and feel that they have made a fortune, but they may have been cheated.
How to distinguish the quality of a hydrogen water cup? Besides tasting the prepared hydrogen water with or without peculiar smell, here is a very simple method to teach you!
That is, buy a TDS (Total Dissolved Solids) test pen (very cheap, about tens of yuan each, Taobao can buy it), fill a hydrogen cup with water (pure water or mineral water), and measure and record the TDS concentration of raw water.
Do not cover the cup, then press the switch to make hydrogen continuously for 20 times, and then check the TDS concentration. If it is a good hydrogen cup, this value should not increase.
If it increases a lot, it means that there are many solids in the water, which may be heavy metals precipitated in the process of cup electrolysis, which is harmful to human body and is not recommended for long-term use.
Second, the principle of hydrogen production Classification of hydrogen-rich water cups
At present, the hydrogen production principles of hydrogen-rich water cups on the market can be roughly divided into these three types:
1. Entry-level hydrogen-rich water cup: hydrogen is produced by chemical method, and magnesium metal is generally used.
Minerals with magnesium as the main component are made by technology, and the principle that magnesium reacts with water to produce hydrogen is used.
Equation: Mg+2H2O=Mg(OH)2+H2↑ Slow reaction produces hydrogen. If hot water is used, the reaction will be strengthened.
Advantages: The hydrogen-rich water cup made based on this principle has simple process and low cost.
Defect: magnesium will be used up, and the filter element needs to be replaced from time to time.
Moreover, this way of hydrogen production will produce magnesium ions, which are needed by the human body, but the human body absorbs a lot of magnesium ions, which increases the complexity of the problem.
In addition, people need to drink a lot of hydrogen water to make hydrogen in this cup, and the role of hydrogen is only shown.
2. Universal hydrogen-rich water cup: ordinary electrolysis method.
This is adopted by most manufacturers of hydrogen-rich water cups at present. Platinum electrode is put into water at the same time, and hydrogen and oxygen are produced and discharged into water at the same time during electrolysis.
Electrode reaction formula: anode: 4oh-4e-= O2 =+2h2o, cathode: 4h++4e-= 2h2 =
However, the anode still has two side reactions, one of which is ozone generation: 3H2O-6e-=O3+6H+.
Another side reaction is chlorine: 2cl-2e-= = Cl2 =
Among them, the Eda cup in Japan is such a way to produce hydrogen by electrolysis.
Many consumers find that Jiangtian Plain Cup is not suitable for China, and it will have an odor when used in China, that is, ozone and residual chlorine.
In the final analysis, the reason is that tap water in Japan can be directly drunk, without organic pollutants such as heavy metals and residual chlorine.
In China, chlorine is added to tap water for sterilization, and the chlorine content of chlorine-containing tap water will increase by more than 5 times after electrolysis.
There is no way to avoid producing ozone.
Therefore, this universal hydrogen-rich water cup generally contains mineral particles to improve the taste, some of which can partially absorb residual chlorine and ozone.
If pure water is used for electrolysis, residual chlorine and ozone will be reduced accordingly. However, many cups using universal electrolysis method in the market cannot produce hydrogen or their hydrogen production capacity is greatly weakened because of the poor conductivity of pure water. If distilled water or deionized water is used, this cup will not work at all.
Advantages: low cost and easy popularization.
Disadvantages: The problems of residual chlorine and ozone cannot be completely solved. Low threshold, numerous manufacturers and uneven quality.
3. High-end hydrogen-rich water cup: SPE proton membrane, pure water electrolysis, hydrogen and oxygen separation.
Hydrogen-oxygen separation hydrogen cup realizes the complete separation of hydrogen and oxygen by SPE proton membrane electrolysis technology, and the hydrogen production equipment at the lower part is provided with an exhaust hole to exhaust the gas except hydrogen produced in the process of hydrogen production by electrolysis of hydrogen-rich water cup, which improves the hydrogen concentration in water and enhances the performance of hydrogen water to human body.
The specific hydrogen production process is as follows:
Using proton exchange membrane, electrocatalyst particles are directly attached to the membrane to form a membrane electrode group. Membrane-electrode assembly embeds active electrodes (catalytic substances) on both sides of solid polymer electrolyte membrane, allowing only protons and water to pass through.
In hydrogen production, the electrolytic reaction of water is carried out on the membrane electrode, which acts as a diaphragm and an electrode.
Water undergoes an electrolytic reaction at the anode of the power supply to generate hydrogen and oxygen, in which hydrogen will lose electrons at the anode and become hydrogen ions, which will reach the cathode through the proton membrane in the form of hydration, while oxygen cannot pass through and can only be discharged.
After the hydrogen ions reach the cathode of the power supply, the electrons obtained from the cathode recombine to form hydrogen, oxygen is discharged from the bottom, and high-purity hydrogen is injected into the water.
Advantages: no residual chlorine and ozone are generated, and the generated hydrogen has high purity and high hydrogen-water concentration.
Disadvantages: Only a few foreign companies can produce SPE electrolyte membranes, such as DuPont and Dow. Many parts of electrolytic cell are expensive, so the cost is high, and the price of hydrogen-rich water cup is not cheap.
Third, the hydrogen-rich water cup pays attention to distinguish between true and false!
When many people choose hydrogen cups, they give priority to hydrogen cups with high hydrogen production concentration.
Indeed, it is generally believed in the industry that the relationship between hydrogen concentration and action is positively correlated. In other words, the higher the hydrogen concentration, the stronger the effect on human health.
The higher the hydrogen concentration in water, the stronger the effect. The industry follows that hydrogen is relatively safe, and increasing the concentration can maximize the pursuit of ideal results.
However, the amount of hydrogen that everyone can drink at a time is limited, so only by increasing the hydrogen concentration in water can the hydrogen concentration in human blood be effectively increased.
Under normal temperature and pressure, the saturated solubility of hydrogen in the laboratory is 1.58mg/L, which is what we often hear: 1.58ppm= 1580ppb.
In real life, it is difficult to reach saturation.
Of course, through a special process, the hydrogen concentration can be very high, but this requires advanced hardware and technology to achieve.
The more effective measure to improve the concentration of hydrogen in water is "hydrogen-oxygen separation", which separates the gas first, and then uses gas-liquid mixing technology to maximize the dissolved amount of hydrogen in water.
This technology is also the technology used in the high-end hydrogen-rich water cup for hydrogen-oxygen separation mentioned above.
Those cheap hydrogen-rich water cups say that the hydrogen concentration can reach or even exceed 1580ppb, which is not reliable. Please choose carefully.
Ok, that's the end of today's popular science time. Advise everyone, for the sake of health, don't be greedy for cheap things, cheap things are not good, and this is always the truth!
Finally, to repeat, before buying a hydrogen-rich water cup, you must know more about relevant professional knowledge. I believe you can buy a satisfactory hydrogen-rich water cup!
