Purified water: Drink or does not drink

Purified water: Drink, or does not drink
Recently, an enterprise declares in the advertisement: The purified water is useless to the health, will stop producing the purified water in the future. Much citizens who drink purified water can't help stunned. But a lot of experts say, up till now, we are not enough to study and understanding of health influence of water, supply water and draw a conclusion now, it is early. It is that a kind of helpless choice experts generally acknowledge to drink the purified water, the maximum advantage of the purified water is to remove the bacterium, virus, heavy metal in the original water, especially organic pollution, this running water punish craft to be unattainable conventionally. The expert studies and is thought, if remains the organic pollution, can produce the by-product that chloroform, tetrachloromethane,etc. may constitute a threat to health in the running water after chlorine is sterilized, and drinking the purified water can avoid this hidden danger. But the biggest shortcoming of the purified water is to remove mineral and microelement essential for human body such as calcium, magnesium, Fluorine, iodine, selenium. There are materials that reveal, the intaking amount of calcium, magnesium while drinking the water should account for 5%- 20% of the total intaking amount, lack normal development that absorption of this part may influence teenagers. There are anxious experts, drinking the purified water for a long time not merely reduces the absorption which benefits the element, the purified water may also be regarded as one at the same time" Water of hunger " ,It benefits the discharge of the element in the body to promote. Danish scholar has said too, have a certain influence on emergence of children's decayed tooth to drink the purified water for a long time. Chen ChangJie is our country's famous environmental medical and health expert, often someone consults him: "This water, that water are multifarious on the market now, what water do you drink after all best? " He always answers like this: "It is best, substantial safely and whether I think or drink the boiled running water. " He says to reporters, if the local running water has reached the national sanitary standard, then, except special occasion, it is unnecessary to regard purified water of several hundred times higher price as the daily drinking water. The experiment that the purified water plants flower has no convincingness in order to prove the purified water is useless to the health, have arranged one group in some television advertising with the purified water separately specially and it is not that the purified water train the contrast lens of the daffodil. The reporter has inquired several experts at this point: Is this convincing? They have shaken the head simultaneously: It is totally two different matters that people drink water and plant and absorb the moisture, do not have comparativity. If use water a little dirtier, perhaps the plant will grow better! The person objecting to drinking the purified water does not hesitate to tell all sorts of purified water and is unfavorable to healthy reason, but the analysis of staying in theory more, has not nearly all put forward convincing epidemiology to investigate the animal experimental result. China prevent the intersection of medicine and the intersection of institute and the intersection of Hubei Province and gift, Assistant Researcher of Ins of Environmental Hyg Monitoring, learn to tell reporters: Transparent and clean that water of the spring runs that Chinese all know the tiger of Hangzhou, the mouthfeel is fresh and comfortable and sweet to slip, it is the in nature good water. Where fortunately on earth? I carried on on-the-spot investigation on a special trip in 1996, measured it in water Total solubility solid (TDS value) It is only 10 milligrams liter, close to drinking the purified water standard. Guangxi Wuming county has places that is known as " Light spring " Groundwater,too it is every one typical purified waters natural, there are 5-6 milligrams liter only value on TDS. The local drinks this kind of water from generation to generation, there is no phenomenon of impairing one's health. U.S.A. water quality association scientific consultative committee points out while drinking the report in a purified water, the report of American Space General Administration, the drinking water TDS value in the space of the astronaut is about 0.05 milligrams liter, and the time that the astronaut stayed in the space has already been as long as more than 1 year at present, any bad reaction did not appear, USN has already had a history of 40 years to drink for the soldier with the sea water distilled, have not found either that diminish the health. The important form of nutrient while drinking the water is from the view point of absorbing the nutrient, China prevent from the intersection of medicine and the intersection of institute and the intersection of Ins of Nutrition Food Hygiene and the intersection of you and researcher Shi Chen say, it is unimportant to drink running water or purified water, the food obtained various nutrition main channels, " Chinese resident's meal guide " that China nutrition learns to be made has not considered the nutrient that people absorbed in water either, because it does without ignoring. So long as rational meal, drink water of the safe hygiene, would not present the alimentary deficiency. Someone has calculated such account: If people take in 1600 grams of running water each day, can get 3.2 milligrams of potassium, 48 milligrams of calcium, 12.8 milligrams of magnesium, 0.22 milligrams of zinc, 0.14 milligrams of irons, copper from it
