Chinese green food development center said: "safe, high quality, nutritious" embodies the quality characteristics of green food. The first characteristic is its safety, that is to say, in a reasonable way of consumption and normal consumption of food will not cause harm to the body's characteristics. As we all know, an adult needs to drink about 2000 milliliters of water every day to maintain the balance of water income and expenditure, if an adult drinks about 2000 milliliters of pure water every day, will it cause harm to the body in the long run? Beijing University of Chemical Technology Water Resources Research Center, Professor Jin Riguang said: "Pure water water molecules are extremely tandem and linear structure, not easy to pass through the cell membrane, which will lead to the loss of beneficial life-related elements in the body to the outside of the body, some sensitive people drink the more the more the thirst is not quenched, the more the more you drink the more you want to drink, lowering the body's immunity, and even cause some kind of disease." China's cardiovascular disease experts, the Chinese Academy of Sciences courtyard soil Professor Wang Shiwen pointed out that: "long-term consumption of soft water with few minerals is one of the causes of atherosclerosis." The Naval Medical Research Institute provided a clinical response: "Zhoushan island warriors generally feel weak after drinking rainwater for six months." The rainwater was tested for lack of minerals and its water quality was similar to pure water. This is an example of the harm caused to the body in a reasonable drinking style and normal drinking volume, which can say that pure water is safe food? China has hundreds of millions of adults drink every day with the same amount of pure water (about 2000 ml) of tap water, natural water or mineral water, drinking for more than ten years, decades have not heard of and did not see a case of reports about harm to the body, compared to the regular drinking tap water, natural water and mineral water is safe, often drinking pure water is not safe.
Two, pure water without nutrition
China Green Food Development Center said: "In addition to safety, high quality, nutrition is also an important feature of green food, green food product standards have a specific embodiment of the requirements of its excellent sensory characteristics, quality and nutritional value." In other words, green food not only requires excellent sensory characteristics and quality, but also requires excellent nutritional value. Pure water has no good nutritional value? Can be answered with certainty: no! As we all know, pure water processing, in the removal of pollutants in the water at the same time also removed from the water essential trace elements and macroelements. Water is an important way for the human body to obtain minerals, under special circumstances or the main source. Tsinghua University, Department of Environment, Professor Wang Zhansheng emphasized: "at the very least, China's residents of the existing dietary structure is relatively single, and can not be comprehensive and natural supplementation of all kinds of elements, so the nutritional benefits of drinking water still can not be ignored." Water nutrition expert, director of the China Medical Promotion Association Healthy Drinking Water Professional Committee, Professor Li Fuxing said: "It has been confirmed that there are nearly 10 kinds of trace elements in the water is essential to the body. China's current dietary structure, many trace elements are difficult to ingest from food, mainly from water. The absorption rate of calcium in water can reach more than 90%, while the absorption rate of calcium in food is only 30%." National Drinking Water Hygiene Team Leader, Professor Zhu Huigang of Shanghai Medical University highlighted: "For drinking water, it is not the purer the better, the inorganic elements in water are in the form of dissolved ions, which can be easily absorbed by the body, so drinking water is an important way for people to take in minerals. Pure water contains little or no minerals, in the past, mainly used in thermal power plant boilers, electronic industry washing, integrated circuit boards. Drinking pure water should be done with caution, especially for children, the elderly and pregnant women is not suitable." Healthy drinking water proposed by the World Health Organization must meet six conditions, namely: free of harmful substances, contain the right amount of minerals, moderate hardness, rich in oxygen, small water molecule group, ph value for weak alkaline. Pure water basically does not contain minerals, hardness is close to 0, containing very little oxygen (distilled water is 0), water molecule group (> 100hz), ph value of 6.0 or so, for the weak acidic. Canada and Russia's drinking water quality standards for hardness shall not be less than 50mg / l (caco3), European **** body and the United States drinking water quality standards to maintain the hardness of more than 60. Obviously pure water does not meet the conditions of healthy water, no nutrition, not to mention the excellent nutritional value, how can we say green food?
Three, long-term consumption of pure water affects health
Water is the most important of the six nutrients on which mankind relies for survival, minerals and trace elements in water is essential to human health. Beijing University of Chemical Technology Life Dynamics and Water Resources Research Center Professor Jin Riguang pointed out that: "water for the origin of life and the continuation of life plays a very important role in the process, in this sense, we can not say that water is used to quench thirst, the far-reaching significance of water is to maintain the continuation of human health life." People in the choice of drinking water, should pay more attention to whether it is conducive to health, pure water is conducive to health? National Development and Reform Commission Public Nutrition and Development Center, Dr. Chai Wei in the "2005 China Drinking Water Industry Forum" at the meeting emphasized that "pure water has a strong ability to dissolve minerals, trace elements, people drink large amounts of pure water, the body's original trace elements, nutrients and nutrients, will rapidly dissolve. Nutrients, will be rapidly dissolved in pure water, and then excluded from the body, so that the nutrients in the body out of balance, a health deficit, is not conducive to good health. Many European countries now stipulate that pure water cannot be used directly as drinking water." The famous American water expert Martin Fox, M.D., in the book "Healthy Water" emphasizes: "Drinking contaminated water and desalinated water (i.e., pure water) will cause harm to our health." China's Naval Medical Research Institute water supply department Ding Nanhu researcher and others, from 1987 to 1994 on the mice for seven years of testing, so that its long-term drinking of distilled water, the results found that the mice grow slower, weight loss, osteoporosis, muscle atrophy, the pituitary gland and renal gland system function is destroyed. Dalian, an island garrison, had been drinking homemade distilled water (pure water), over time, officers and soldiers suffered from a variety of mineral deficiency diseases. Chen Mengxiong, a senior academician of the Chinese Academy of Sciences, believes that: "long-term consumption of pure water will reduce the body's intake of minerals and beneficial elements. From the relationship to health, natural water is better than pure water, mineral water is better than natural water." A large number of animal testing and clinical responses at home and abroad have proved that long-term consumption of pure water is harmful to health. For this reason, the Shanghai Municipal Education Commission has issued a notice: in principle, since the beginning of the 1997 school year, the primary and secondary schools, kindergartens should no longer use pure water as students, young children's drinking water. Shanghai Administration for Industry and Commerce has also issued a notice: pure water advertisements should not publicize "long-term drinking" and pure water with milk powder, cooking, etc. In March 2003, some primary and secondary school students in Hangzhou City, said goodbye to the pure water, there are more than 100,000 primary and secondary school students have been drinking mineral water. Recently, China Consumers' Association has issued a formal warning: teenagers, children and the elderly should not drink pure water for a long time. Green food to health as the basic goal, and long-term consumption of pure water, not only can not play a role in promoting health, but will cause harm to the body, how can we say 鈥縁 color food?
Since drinking pure water into the market, the drink what water has been the majority of consumers are very concerned about the topic, after several years of intense debate, the conclusion is clear, long-term drinking pure water is not conducive to health, mineral water is the ideal drinking water. National drinking water health team leader, Shanghai Medical and University Professor, doctoral supervisor Zhu Huigang said: "mineral water and general drinking water is different, it contains lithium, strontium, zinc, iodine, selenium, and other trace elements, and some are also rich in macronutrients, so it can replenish the human body needs of the trace elements and macronutrients, regulating the body's acid-base balance, these features are general These characteristics are not available in general drinking water. Mineral water is the crown of healthy drinking water." China medical control center environment institute health senior expert Xu Fang researcher pointed out: "mineral water to contain a certain amount of beneficial to human health minerals, trace elements or carbon dioxide gas and different from ordinary groundwater. Since this kind of water is not contaminated by foreign man-made pollution and does not contain calories, it is an ideal health drink for human beings. We have conducted animal tests on more than a dozen kinds of mineral water representative of our country, and found that these mineral waters have different degrees of tumor suppression effect, and some epidemiological survey data also indicate that mineral water does have a great effect on promoting muscle health and prolonging life." Drinking natural mineral water that meets the medical mineral water quality standards has a preventive, therapeutic and symptom-reducing effect on certain diseases. Water is the fountain of health. Each person should drink at least six to eight glasses of water a day, which is the healthy perception of water.
Drinking clean, unpolluted mineral water has become a trend; some people insist on drinking plain water. In recent years, more people believe that through the drinking water filter, in order to drink pure and healthy water.
What kind of water is healthy to drink?
Drinking eight glasses of water a day is a recognized standard of health. The average adult weighing about 60 kilograms needs to consume 2.5 liters of water per day. It is thought that this water can be consumed from a variety of diets.
Mineral water is a high blood pressure "killer"
Water is an integral part of the body's cells. When cells lose water, they lose their function. Water helps the body to absorb and digest food, and also helps to regulate body temperature, and also plays a wetting and sliding role in the joints.
People are encouraged to drink more plain water because some mineral waters are high in sodium, which is one of the main culprits of high blood pressure. In addition, consuming too much sodium can take a toll on the kidneys.
Pure water can effectively promote the body's metabolism. Concentrated beverages, such as coffee, tea and sodas, not only fail to hydrate the body, but also take water from the cells, leading to dehydration, and should not be consumed in excess.
Bottled water sold locally includes mineral water, purified water and distilled water. A spokesman for the Agri-Food and Veterinary Authority (AVA) said:
"Bottled water is either locally produced or imported from outside the country. Manufacturers and importers must ensure the safety of this water. Local manufacturers of bottled water are licensed by AVA. The AVA regularly inspects these manufacturers to ensure that production meets health standards."As for imported bottled water, the AVA requires manufacturers to prove that the product is safe for drinking by having a license and product health certificate issued by the local government.
Bottled water sold in the local market has to be approved by AVA before it can be put on the shelves. Samples of the products are also taken for testing at regular intervals.
When drinking bottled water, people should avoid drinking the same bottle with two or more people*** to avoid spreading germs.
Knowing the three main types of drinking water
Tap water
Tap water does not contain as many minerals as mineral water, however, it does contain chlorine and fluoride. Chlorine is used to kill bacteria and fluoride prevents tooth decay. Singapore has one of the safest waters in the world, made according to standards provided by the World Health Organization, which include microbial content and dozens of minerals.
Distilled water
Distilled water is also available on the market today, but there are not many options. It is also packaged in such a way that many people confuse it with mineral water because it is not different from regular mineral water.
Distilled water is artificially purified water, purity of 99.9%, but the mineral content of the water has been insignificant. The role of this "pure water" in the body is simply to serve as transportation, such as the cellular tissues rejected out of the body.
Mineral water
There are no less than 20 types of mineral water on the market. Mineral water is a natural source of water that originates underground, gushes naturally or is artificially extracted, and contains an abundance of iron, calcium, sodium and magnesium. In the process of treatment, mineral water does not add minerals, carbon dioxide, etc.. No chlorination or other treatment of the water is allowed, except for physical sterilization. In addition, it must be filled and sealed with automatic equipment to avoid contamination.
Generally speaking, purely from the ground, without artificial processing, filtered water can be called "natural mineral water", such as artificially extracting clean water from the ground, after a moderate sterilization process, that is, known as "general mineral water".
International standards for mineral water
Mineral water, such as international standards, the regulations are very strict.
One, height: 50 to 2500 meters above sea level for spring water, 2500 meters above the mountain spring water.
Second, the source of water: within a radius of 10 kilometers can not have the existence of the cause of water pollution.
Three, the spring water must be naturally gushing, filtered through other rock formations, and tested to be rich in natural minerals.
Four, must be in the origin of direct packaging, the best sealing cans also be completed within 24 hours to ensure that the cans are sterile, no pollution.
Fifth, the water quality must be about 10 years of continuous testing to determine the amount of minerals, and access to the International Water Quality Association logo, in order to confirm its stability.
There are many different kinds of bottled water on sale in the market, with different brands and names of water, consumers should pay more attention to distinguish. For example, natural spring water (natural spring water), natural mineral water (natural mineral water), sparkling mineral water (sparkling mineral water) Some are drinking water (drinking water) or distilled water (distilled water).
Rolling and rolling leads to illness
Raw water
"Raw water" means tap water. Local tap water meets the standards provided by the World Health Organization. If you go abroad, try to avoid drinking tap water, because the health standard is different, some tap water contains a variety of harmful bacteria, viruses and human and animal **** parasites. Drinking it can easily cause acute gastroenteritis, viral hepatitis, typhoid, dysentery and parasitic infections.
Aging water
Commonly known as "dead water", that is, a long time to store the water. Drinking this water, for minors, the cell metabolism will slow down significantly, affecting the body's growth and development; middle-aged and elderly people will accelerate aging; according to medical research, esophageal cancer, gastric cancer incidence increased, may be related to long-term drinking aging water.
Thousand rolls of water
Thousand rolls of water is boiling on the stove overnight or for a long time of water, and in the electric kettle repeatedly boiled water. This water is boiled for too long, the water does not play a material, such as calcium, magnesium and other heavy metal components and nitrite content is very high. Often drink this water, will affect the gastrointestinal function, temporary diarrhea, bloating, etc.; toxic nitrite, will cause hypoxia of the organism, the serious will be coma and convulsions, and even death.
Re-boiled water
Some people are accustomed to the hot water bottle in the remaining warm water, re-boil and then drink, the purpose is to save water, gas, electricity and time. But this practice should not be encouraged. Because the water boiled and boiled, so that the water evaporates again, nitrite will rise, often drink this water, nitrite will accumulate in the body, causing poisoning.
Bottled water can damage teeth?
New Zealand medical report pointed out, "Drinking bottled water often, causing insufficient fluoride, will damage your teeth" is not necessarily true, because people can get fluoride from sources other than drinking water.
The report said that children and adolescents who drink bottled water and filtered water inadvertently reduce their intake of fluoride because these waters contain less fluoride than tap water.
So what's the best way to get enough fluoride? Toothpaste, which is rich in fluoride, is good for dental health, said local dentist Wong Jee-ying. Instead, you should pay more attention to drinking highly acidic beverages and sports drinks, as the acidity of these drinks can erode teeth.
He said that besides water and toothpaste, tea also contains fluoride. However, excessive fluoride intake can damage tooth enamel and have a negative effect on bones
