The following five kinds of water will form nitrite and other toxic and harmful substances to a certain extent, which will cause certain harm to the human body. Do not drink five kinds of water Aging water: commonly known as 'deadwater', that is, long-term storage of immobile water. Often drinking this kind of water, the minor will cause the cell metabolism to slow down significantly, affecting physical development; middle-aged and old people will accelerate aging; many places esophageal cancer, gastric cancer incidence is increasing, may be related to long-term consumption of aging water. Toxic substances in aged water also increase as the water storage time increases. Thousands of boiling water: Thousands of boiling water is boiling water on the stove for one night or for a long time, and the water boiled repeatedly in an electric water heater. This water is boiled for too long, the non-volatile substances in water, such as calcium, magnesium and other heavy metal components and nitrite content is high. If you drink this water for a long time, it will interfere with people's gastrointestinal function, temporary diarrhea, abdominal distension; toxic nitrite will also cause the body to hypoxia, severe cases will be coma convulsions, and even death. Steamer water: The steamer is steamed, steamed, steamed, etc. The nitrite concentration in the steamer is high. Regular consumption of this water, or the use of this kind of glutinous rice porridge, can cause nitrite poisoning; scale often enters the body with water, but also causes digestive, nervous, urinary and hematopoietic system lesions, and even cause premature aging. Not open water: People drinking tap water are sterilized and sterilized. Thirteen kinds of harmful substances can be separated from chlorine-treated water, among which halogenated hydrocarbons and chloroform also have carcinogenic and teratogenic effects. When the water temperature reached 90°C, the content of halogenated hydrocarbons rose from 53 micrograms per kilogram to 177 micrograms, which exceeded the national drinking water hygiene standard by 2 times. Experts pointed out that drinking unboiled water increases the risk of bladder cancer and rectal cancer by 21%-38%. When the water temperature reaches 100°C, these two kinds of harmful substances will be greatly reduced as the vapor evaporates. If it continues to boil for 3 minutes, it is safe to drink. Re-boiled water: Some people are accustomed to re-boil the remaining warm boiled water in the hot water bottle, aiming to save water, save coal (gas), and save time. However, this 'saving' is not sufficient. Because the water burns and burns, the water evaporates again, and the nitrite rises. This water is often consumed. Nitrite accumulates in the body. What kind of water is good? Do you drink hard water or soft water? To understand whether it is good to drink hard water or soft water, first understand the relationship between calcium and magnesium ions and human health. Calcium and magnesium ions are essential daily human body nutrients, if the water has a certain hardness, by drinking water can be added to a certain amount of calcium and magnesium ions. If you are someone who takes soft water for a long time, you need to supplement it by other means. However, water hardness is too high and too low is not good, because the hardness of water is closely related to some diseases. In regions with high water hardness, the incidence of cardiovascular disease in the population is low, but the incidence of kidney stones increases with the hardness of water. Most of southern China is soft water, and northern areas are mostly hard water. China's drinking water regulations do not exceed 25 degrees, and the most suitable drinking water has a hardness of 8-18 degrees, which is mild or moderate hard water. The softness and hardness of the water are also related to the taste. Hard water is refreshing. Most mineral waters have high hardness, which makes people feel refreshing and delicious. Soft water appears to be light and tasteless. However, using hard water to make tea and brewing coffee will affect the taste. Some food processing water is more stressful, hydraulic will affect food processing, easy to cause protein precipitation, inorganic salt precipitation or more difficult to cook, and drink water and soft water is better. Boiler water should generally be hardened by hard water, otherwise accidents may occur due to too much scale. Do you drink pure water or drink tap water? At present, the opinions of experts are inconsistent as to whether drinking pure water or drinking tap water is good. Some experts believe that drinking water is a supplement of water and there is no need to consider nutritional issues. Other experts believe that there are many trace elements and inorganic salts in tap water that are beneficial to humans. So what nutritious water in the end? 1000 ml of water, zinc, iron content of less than 0.2 mg, adults need to add zinc daily 10 mg -15 mg, iron 12 mg -18 mg. The daily intake of less than 1 milligram of trace elements from the water is insignificant compared to the trace elements required by the human body. However, the higher calcium and magnesium content in the water can still benefit the human body. The real pure water is filtered through layers, and generally removes impurities, trace elements, inorganic salts and pathogenic bacteria in the water. It is safe, non-toxic, non-polluting, and is good for the human body. The missing elements can be Ingested from food. Therefore, if economic conditions permit, what is purchased is pure water, which is human progress. However, due to the fact that the production of purified water is not standardized at the moment, there is a lot of confusion. If you purchase unqualified products, it will be harmful to your health. So what's the problem with drinking tap water? Tap water is produced under strict control of the quality of the tap water plant. Drinking tap water can be assured. However, it is worth noting that some high-rise building water tanks contain pollution. As for the scale of tap water, it is caused by calcium and magnesium ions in the water. It has no adverse effects on the body. The tap water is economical and the ordinary working-class people are not necessarily catching up with the new trend of the market. In short, there is no need to think too much about the issue of drinking water. Drinking water means supplementing water and there is no need to worry about nutrition. As for what kind of water to drink, it should depend on economic conditions and whether it is true pure water.
