Now we have entered the era of diversified drinking water, from natural mineral water, mineral water, pure water, distilled water, spring water, and then to the weak alkaline water, oxygen-enriched water, magnetized water, ion-exchanged water, activated water, small molecule group of water and so on abound in the market, so that the consumer is full of doubts and difficulties in choosing. Therefore, in order to standardize the drinking water market, a new national standard – “National Standard for Food Safety Packaged Drinking Water” (GBl9298-2014) requirements, in addition to natural mineral water has a separate national standard, after the market packaged water is only divided into drinking water and other drinking water, that is, not purified water is attributed to Other drinking water. So in the market, we will only see natural mineral water, pure water, other drinking water, three kinds of packaged drinking water name, the other a lot of “concept of water” name will no longer exist. Here we talk about natural mineral water, pure water and tap water. What is natural mineral water Natural mineral water is rich in trace elements beneficial to the human body of natural drinking water. It is in fact a mineral resource of the country, the mining needs to obtain the “mining license” issued by the Department of Land and Resources. High-quality mineral water is usually characterized by low sodium, moderate mineral content, containing one or several characteristic trace elements. For example: 1, strontium has the prevention and treatment of osteoporosis, the role of strong bones; 2, zinc can regulate human hematopoietic function, promote growth and development, enhance immunity; 3, selenium can prevent cancer, prevention of cardiovascular disease, diabetes, Keshan disease, effective protection of young people’s eyesight; 4, metasilicicic acid can enhance the elasticity of the skin to reduce the production of wrinkles, delay aging. Minerals in water are beneficial to cardiovascular A scientific research team based on the New Zealand rabbit and young male population study results confirm that drinking low mineral water has a relatively high risk of cardiovascular disease. The study demonstrated in both animals and humans that drinking two types of bottled water with very low mineral content (artificially mineralized water and purified water) increased blood levels of several independent indicators of cardiovascular risk – homocysteine, ultrasensitive C-responsive protein, and arginase – predicting a relatively high risk of cardiovascular disease. risk. This suggests that minerals in drinking water are essential for good health, especially for the cardiovascular system. Pure water is clear and transparent, without any minerals. Its water purification measures include: precipitation, filtration or reverse osmosis, activated carbon filtration, distillation, etc. Although it achieves the purpose of removing bacteria, it also removes trace elements and minerals essential to the human body. Short-term citation of pure water can help the body detoxification, but a large number of long-term citation of pure water, is not conducive to the absorption of various nutrients needed by the body and metabolism. Water has a “hard and soft” points in nine countries have conducted more than 50 studies show that: the hardness of drinking water characteristics and cardiovascular disease (heart disease, hypertension and stroke) and a few other diseases have a statistically significant link between. Cardiovascular disease is inversely correlated with the hardness content of drinking water, or positively correlated with the degree of water softening. Studies in the United States and Canada have demonstrated that the age-corrected mortality rate for cardiovascular disease is 15% to 20% higher in populations drinking very soft water than in populations drinking hard water. This difference may be as high as 40% as reported in the UK. There is no clear distinction between hard water and soft water, and it is generally believed that water with CaCO3 less than 75mg/ L belongs to soft water, and more than this concentration is hard water. What is tap water Tap water is water extracted from rivers, lakes and groundwater to the water plant, and then after a number of processes to enter the user’s home. In terms of composition, tap water also contains minerals. However, China is one of the countries with the most polluted water resources in the world. This is mainly due to the secondary discharge of water pollution from daily use and industrial production. So tap water may not be as pure as you think, it may contain heavy metals, compounds, etc., and even some old water pipes often burst, which makes it easy for secondary pollution to occur. Tap water contains some impurities on the taste also has a certain impact. Algae content is high, there are some earthy; chlorine agent with high dosage, there is bleach flavor. Some volatile pollutants by boiling, with the steam evaporated, but some organic matter, especially chlorine by-products will increase with the increase in boiling time. So for now tap water is safe water, but not healthy water. How can you drink healthy water Nutritionists believe that if you have a regular diet in your daily life, you do not need to drink mineral water purposely to replenish nutrients. However, if you are in a disease area, it is advisable to drink mineral water with high selenium and iodine content; in a disease area with large bones and Keshan disease, it is advisable to drink mineral water with high selenium content; and in a high fluoride water area, it is necessary to drink low-fluoride mineral water. We can also purchase home water purifier, tap water filter to purify tap water, and then according to personal conditions, local environment, etc., moderate drinking natural mineral water and pure water, so as to achieve the goal of healthy drinking water.
