Editor's note

Was said to weave his magic in the market feature water, magnetic devices, infrared therapy equipment, Massager, oxygen makers, and so on, can achieve its promotional efficacy? The "proof" section combined with the life, times, the times of health conducted a series of investigations.

"XX high energy healthy water drinking machine, water health theory development ... ... High energy healthy, alkaline water is pollution-free, small molecules of water, is longevity village drinks ' longevity ' ... ... "this is described on the official website of a certain brand of water filter. Press enter in search engines "household multi-purpose water making machine", that is, more than 110,000 results.

In recent years, as people's concern about drinking water safety, a variety of water purification equipment came into being, besides Purifier,, also claimed responsibility for many products, such as diabetes, high blood pressure is effective, even cancer. Water purification system the function of water? Health and cure diseases, "magic water" exist? This reporter interviewed a number of medical specialists and expert on water.

Alkaline water health benefits?

"In response to" national drinking water standard pH value is due to pipeline transportation concerns, not health related

Eco-weak alkaline water machine, alkaline water machine, alkaline ionized water making machine ... ... These water purification devices are main concepts: product preparation of weak alkaline water feature. Manufacturers claim that weak alkaline water is most suited to the human body needs healthy water, nutrition and health care function, not only to promote human development, and to prevent the occurrence of some chronic diseases.

Alkaline water is healthier? Head of health protection association professional Committee of healthy drinking water of Beijing Zhao Feihong introducing, there is at present no evidence to prove that the pH value of the water and health. Experts said the index does have a pH value of drinking, range is 6.5-8.5, but it's not health indicators, primarily for preventing lower pH values of liquid metal pipe corrosion considerations.

Small molecules of water, alkaline water machine water rationing to most attached, the resellers such forms easier for water to be absorbed. Experts said that some water such as water molecules are smaller, but nor is there any evidence that it is directly related to health, much less a cure.

In order to prove the "weak alkaline water, small numerator Regiment water is healthy" businesses, "says health drinking water quality standards by the World Health Organization noted that high quality health water was alkaline pH values; small molecules, penetration, and solubility.

But journalists have access to the information found, currently GM's third edition of the World Health Organization drinking water standards there are five indicators. Only reference is the fifth-largest chapter of the pH value "from inorganic portions of" the 10th, as their standards and our current standards, is 6.5-8.5, reason as: water with low pH value has certain corrosive, high pH value of the water will have a slippery feel and smell. The World Health Organization drinking water standards, and no mention of "weak alkaline water for health" and "small numerator Regiment water" concept.

Feature "magic water" cures diseases?

"In response to" experts say I have never heard of water treatment efficacy may not promote Ford products

In addition to the alkaline water machine water rationing, home water softener, magnetic Water Purifier, home of ozone water, and so is also the best-selling products. Soft water machine claimed "soft water containing oxygen volume high, hardness low, can prevent stones disease, reduce heart kidney burden, also has beauty of effect"; magnetized water machine claimed "can cough to sputum, and prevention constipation, wash foot foot not stink, wash hand smooth"; ozone water machine is said can "makes water in the of oxygen content increased, water became activity water, not only dissolved sex, and penetration force enhanced, also can activated aging of cells, accelerated metabolism, thereby increase people of immunity".

Apart from weak alkaline water, water, ozone water, and "household multifunctional water making machine" manufacturers claim that the preparation of "functional water" can cure many diseases, such as diabetes, high blood pressure, gout, liver disease, migraine, physical illness, backache, stones and even cancer.

Features the magic water has such a big effect?

"I never heard of such a thing, I don't think it's possible. "Professional Committee of Chinese Association of the integration of Chinese and Western medicine diabetes Vice Chairman Wang Xuemei said.

Chinese Academy of medical sciences fuwai cardiovascular disease hospital, cardiology chief physician Zhang Jian says, "magic water" cures diseases extremely unscientific, are wide of the mark. "Water is mainly composed of hydrogen and oxygen, having special effect no matter how impossible, unless you add other substances. After you add other material, it is not pure water, should drink the drink, how to vary. ”

Zhao Feihong stressed that even some water making machine counts and activates water molecules, enhanced solubility, but there is no test can prove the effect.

In addition, some foreign technology banner promoting a product more outrageous. As a known as coming from Japan, "water conditioner water," says its "system on diabetes, allergies, high blood pressure, skin diseases, respiratory diseases, diseases of the digestive system, nervous system disease, AIDS, cancer, and various viruses have very good effect. ”

Reporters in Japan found that this "water conditioner water" in the local dispute, not water purification products in the mainstream. Japan selling water purifiers to antibacterial and filtering, all products can be sold as dietary supplement product, though not curable, "magic water". Manufacturers in sales, said that water can cure diseases, are exaggerated propaganda, will be subject to punishment.

"Functional water internationally also controversy, even the birthplace of the concept of functional water Japan, focusing only on the electrolysis of water. In China, water is a concept not recognized, electrolysis of water separate from the ' water ', its preparation equipment is ' medical health ', required by the State food and Drug Administration approval. "Zhao Fei Hong said.

Reporters on the SFDA website found very few approved water system is defined as "electrolytic water generating device", which notes: "generated with the disinfecting effect of electrolyzed strong acid water supplies to health institutions within each Department".

Beijing municipal health authority told reporters at a crisis centre official Wei Xiangdong, including many household water rationing, the Water Purifier are wading, above the provincial level health supervision Department.

It is understood that the State Health Commission to develop effective October 1, 2013, the drinking water safety instruction management norms provided for in the sixth of the product label, wading in the product labeling and instructions shall not be of note:

(A) express or hinted has control disease role of content; (ii) false, and exaggerated, and makes consumers misunderstanding or cheat sexual of text, and graphics and and life drinking water has nothing to do of content; (three) "acid water", and "alkaline water", and "activation water", and "small molecular mission water", and "features water", and "energy water", and "rich oxygen water", content; (four) legal regulations and the standard specification prohibited callout of content.

Hard to the body harmful?

"In response to" metal cations, such as calcium and magnesium are not pollutants, scale does not affect health

The calcium and magnesium ions in tap water and fouling in the body harmful? Zhao Fei Rainbow view, should not blindly pursue reducing metal cations, such as calcium and magnesium concentrations, they are not pollutants, produce scale that do not affect health.

Provisions of the drinking water standard in force in the country, water hardness should not exceed 450 mg/l; World Health Organization drinking water standards existing in the absence of water hardness values based on health criteria. But Zhao Feihong reminder, within 6 months of the baby's kidney development is not yet complete, consider using a water purification equipment to reduce water hardness.

What kind of water is healthy water? Experts say that for the average family, running water to boil is sufficient; pollution the more serious or a downstream area, recommend the use of water purification equipment.

Water purification equipment on the market a wide range, which in the end a good effect? Huazhong University Tongji Medical College Professor Wu Zhigang believes that from the water purification effect, reverse osmosis is better than UF. Feihong Chao also said that people living in the lower reaches of the River in reverse osmosis water purifiers as well, can effectively filter out impurities, organic and pesticide residues, etc.

Zhao Feihong reminded, ozone water machine with caution, because ozone is strong oxidizing agents, long-term drinking this water is likely to cause injury to the oral cavity and gastrointestinal mucosa.

　　编者的话

　　市场上被说得神乎其神的功能水、磁疗设备、红外治疗设备、制氧机、按摩仪等，能否实现其所宣传的疗效？“求证”栏目联合《生命时报》、《健康时报》进行了系列调查。

　　“××高能健康水直饮机，以健康水理论为基础研发……高能健康水是无污染、弱碱性、小分子团水，是长寿村人喝的‘长寿水’……”这是某品牌净水器官方网站上的介绍。记者在搜索引擎中输入“家用多功能制水机”，即获得超过11万个结果。

　　近年来，随着人们对饮水安全的关注，五花八门的净水设备应运而生，除净化过滤外，不少产品还声称对糖尿病、高血压等有疗效，甚至可以抗癌。净水器能制出这些功能水吗？保健治病的“神水”是否存在？记者就此采访了多位医学专家及水研究专家。

　　弱碱性水有利健康？

　　【回应】 国家制定饮用水pH值标准是出于管道运输考虑，与健康无关

　　碱性生态水机、弱碱性能量制水机、碱性离子水机……这些净水设备都主打一个概念：产品具有制备弱碱性水的功能。厂家声称，弱碱性水是最符合人体需求的健康水，有营养保健作用，不仅能促进人体发育，还可以防止一些慢性疾病的发生。

　　弱碱性水更有利于健康吗？北京保护健康协会健康饮用水专业委员会负责人赵飞虹介绍，目前并没证据证明水的pH值与健康有关。专家表示，我国生活饮用水指标中确实有pH值一项，范围是6.5—8.5，但这并不是健康指标，而主要是出于防止金属管道被pH值较低液体腐蚀的考虑。

　　小分子团水，大多依附碱性水制水机存在，商家宣称这样形态的水更易被吸收。专家表示，有些水比如矿泉水的分子团确实较小，但目前也没有任何证据可以证明它与健康有直接关系，更不用说治病了。

　　为了证明“弱碱性水、小分子团水有益健康”，有商家称，“世界卫生组织提出的优质健康饮水标准指出，优质健康水应pH值呈弱碱性；小分子团，渗透力强，溶解性好。

　　但记者查阅资料发现，目前通用的《世界卫生组织饮用水标准》第三版共有五大项检测指标。其中唯一提到pH值的是第五大项第二章“无机部分”第10条，其标准与我国现行标准一样，为6.5—8.5，原因表述为：低pH值的水具有一定腐蚀性，而高pH值的水会有滑腻感和异味。《世界卫生组织饮用水标准》并没提到“弱碱性水有利于身体健康”及“小分子团水”的概念。

　　功能“神水”能治病？

　　【回应】 专家表示从未听说水能治病，涉水产品不得宣传功效

　　除了碱性水制水机外，家用软水机、磁化净水机、家用臭氧水机等也是畅销产品。软水机宣称“软水含氧量高，硬度低，可防止结石病，减轻心肾负担，还有美容之效”；磁化水机宣称“可以止咳去痰、预防便秘，洗脚脚不臭，洗手手光滑”；臭氧水机则称能“使水中的氧气含量增加，水成为活性水，不仅溶解性、渗透力增强，还能激活老化的细胞，加速新陈代谢，从而提高人的免疫力”。

　　除了弱碱性水、磁化水、臭氧水，还有“家用多功能制水机”厂家声称，其制备的“功能水”能治疗多种疾病，如糖尿病、高血压、痛风、肝病、偏头痛、生理病、腰酸背痛、结石，甚至抗癌。

　　功能神水有这么大作用？

　　“我没听说过这种事，我觉得不太可能。”中国中西医结合学会糖尿病专业委员会副主任委员王学美说。

　　中国医学科学院阜外心血管病医院心内科主任医师张健认为，“神水”能治病的说法极不科学，很不靠谱。“水主要由氢和氧构成，不论怎么处理都不可能具有特殊疗效，除非添加其他物质。而添加了其他物质后，也就不是单纯的水了，该不该喝、怎么喝都要因人而异。”

　　赵飞虹强调，即便是一些制水机能够起到活化水分子、增强溶解性的作用，但现在没有任何试验可以证明其效果。

　　另外，一些打着国外新技术旗号的产品宣传得更为离谱。比如一种号称来自日本的“水素水”称，其“对糖尿病、过敏、高血压、皮肤系统疾病、呼吸系统疾病、消化系统疾病、神经系统疾病、艾滋病、癌症，及各种病毒都有很好的疗效。”

　　记者在日本调查发现，这种“水素水”在当地就存在争议，并非净水产品的主流。日本销售的净水器以除菌和过滤为主，所有产品可作为健康辅助商品进行销售，但并非可以治病的“神水”。厂家如果在销售时说这种水可以治疗疾病，就属于夸大宣传，会被处罚。

　　“功能水在国际上也存在争议，就连功能水概念的发源地日本，也只将研究重点集中在电解水上。而在我国，功能水是一个没有被认可的概念，电解水独立于‘功能水’之外，其制备设备属‘医疗保健器械’，需由国家食品药品监督管理总局审批。”赵飞虹说。

　　记者在国家药监局网站查询发现，极少数通过审批的制水机均定义为“电解水生成装置”，其功能备注为：“生成具有消毒杀菌作用的强酸性电解水，可向医疗卫生机构各科室内供应”。

　　北京市卫生监督所应急中心相关负责人魏向东告诉记者，包括净水器在内的多种生活用制水机都属于涉水产品，归省级以上卫生监督部门管理。

　　据了解，国家卫生计生委制定于2013年10月1日起施行的《涉及饮用水卫生安全产品标签说明书管理规范》第六条规定，涉水产品标签和说明书中不得标注：

　　(一)明示或暗示具有防治疾病作用的内容；(二)虚假、夸大、使消费者误解或者欺骗性的文字、图形以及与生活饮用水无关的内容；(三)“酸性水”、“碱性水”、“活化水”、“小分子团水”、“功能水”、“能量水”、“富氧水”等内容；(四)法律法规及标准规范禁止标注的内容。

　　硬水对身体有害吗？

　　【回应】 钙镁等金属阳离子不是污染物，水垢不影响健康

　　自来水中的钙、镁离子和水垢对人体有害吗？赵飞虹认为，不应盲目追求降低钙、镁等金属阳离子的浓度，它们不是污染物，形成的水垢也不影响健康。

　　国家现行的《生活饮用水标准》规定，自来水硬度不得超过450毫克/升；世界卫生组织现行的饮用水标准中，没有提出水质硬度基于健康的准则值。不过赵飞虹提醒，6个月以内的婴儿肾脏发育尚不完全，可考虑用净水设备降低水质硬度。

　　什么样的水才是健康水？专家表示，对一般家庭来说，自来水烧开就足够；在污染较严重或河流下游地区，建议使用净水设备。

　　市场上净水设备种类繁多，到底哪一种效果好？华中科技大学同济医学院教授吴志刚认为，从净水效果比较，超滤不如反渗透。赵飞虹也表示，生活在江河下游的人以反渗透净水器为好，能更有效地滤掉杂质、有机物及农药残留等。

　　赵飞虹特别提醒，臭氧水机要慎用，因为臭氧属于强氧化物，长期饮用这种水有可能对口腔及胃肠黏膜造成损伤。
