Turn off the "high-end water" filter and see what they really look like
2022-07-04
As the saying goes, water is the source of life. Recently, the weather has been extremely hot, and the water loss rate in the human body has accelerated. Therefore, it is necessary to supplement water in time to maintain a normal metabolic state. In addition to our daily mineral water and purified water, there are many expensive water on the market, such as baby water, enzyme bubble water, oxygen enriched water, etc. So, are these "high-end water" really more "high-end" than ordinary water? In response to this problem, the reporter of science and technology daily interviewed relevant experts. Packed with various "magical" effects Some time ago, the media exposed the chaos of alkaline water marketing. The alkaline water scam has been exposed, but all kinds of water packaged with "new concepts" on the market are still emerging in endlessly, with dazzling functions such as weight loss, sleep support, antioxidant... Etc. Let's first take a look at the "magical" effects of these "high-end water" in the mouth of businessmen. In view of the immature immune system and metabolic system of infants and young children, businesses have launched the baby water with the concept of "sterility, low sodium and light mineralization", saying that it is produced by high-temperature sterilization and sterile production line, so it can ensure the safety of drinking water for infants and young children. In addition, the package of the product also indicates that the indicators of heavy metals and other substances harmful to human body in this water are lower than the national standards. The efficacy of oxygen enriched water is more "magical". Some businesses said when promoting oxygen enriched water that when the human body is lack of oxygen, there will be many adverse consequences. Drinking oxygen enriched water can increase the oxygen content in the human body, and then play a certain role in health care, such as anti fatigue, anti-aging, etc. As enzymes are accepted by more and more people, some businesses have launched enzyme bubble water. Many buyers were attracted by the 232 plants in their ingredient list, and said that drinking this bottle of water "is like drinking a whole vegetable market", and some even said that "the periodic table of elements is not complete". Businessmen claim that due to the addition of enzymes, this water has the effects of regulating the intestines, reducing weight, helping sleep and so on. There is a suspicion of "IQ tax" So, are these "high-end water" value for money or "IQ tax"? Chen Yaqin, a doctor of Tianjin Meizhong Yihe Pediatrics, said in an interview with science and Technology Daily that excessive intake of minerals and salt will indeed affect infants' bodies. The World Health Organization recommends drinking water suitable for infant feeding: sodium ≤ 20 mg / L, sulfate ≤ 200 mg / L, magnesium ≤ 40 mg / L. "However, drinking water is not the main way for infants to obtain trace elements. It mainly depends on diet, so even if the water contains some trace elements, it has little impact on their health." Chen Yaqin said. The sterility emphasized in baby water can be easily realized as long as the water is boiled. "Before entering thousands of households, tap water will be strictly purified and sterilized in the waterworks." Chen Yaqin said that if someone is worried that the tap water contains chlorine, they can boil it for another 2 to 3 minutes after the water is boiled, so that the chlorine in the tap water "runs" out. "Baby water is not much higher than tap water. There is no need for treasure mothers to buy it at a high price." Chen Yaqin said. As for oxygen enriched water, Meizhen, a lecturer in the Department of chemistry, School of science, Tianjin University of science and technology, said that it was impossible to replenish oxygen for the human body by drinking water. "Even if the oxygen is dissolved into water by pressurization and sealed, after the water bottle is opened, the oxygen may 'run' away under the action of pressure." Mei Zhen questioned that even if some oxygen is dissolved in the water, it is difficult for oxygen to be absorbed by the human body through the digestive tract mucosa. It is obviously unreliable to supplement oxygen by "drinking" oxygen. "In addition, people in an oxygen-containing environment will produce free radicals, which is also one of the main reasons for human aging. If the human body consumes more oxygen, there will be more free radicals, which will accelerate human aging." Mei Zhen believes that the so-called oxygen enriched water is an "IQ tax". Enzyme is the name of enzyme in Japan. The light industry standard "guidelines for the classification of enzyme products" issued by the Ministry of industry and information technology of China defines enzyme as a product containing specific bioactive ingredients prepared by microbial fermentation with animals, plants, fungi, etc. as raw materials, with or without additives. "Its bioactive components include various nutrients provided by plant raw materials and microorganisms, plant functional chemical components in natural plants, and some active substances produced by fermentation, including amino acids, peptides, vitamins, etc." Tan Guijun, director of the Nutrition Department of Tianjin First Central Hospital, said that enzymes are often advertised to have the effects of weight loss, anti-cancer, anti-aging and so on, but the actual effect may not be completely ideal. The reporter saw an enzyme bubble water on an e-commerce platform. Its enzyme content is not much, and the executive product standard is gb/t 10792, which is the same as that of most carbonated beverages. "Enzyme is just a selling point of this water. Enzyme bubble water is not much different from ordinary water." Tan Guijun said. (outlook new era)
