With the improvement of people's living standards and the enhancement of health awareness, more and more consumers are accustomed to buying bottled water or bottled water in their daily life. Mineral water, natural water, distilled water...... There are many kinds of drinking water on the market, which makes people pick, what is the difference between these different names of water? Wang Bing of the Environmental Sanitation Institute of the Municipal Center for Disease Control and Prevention will introduce it to you.
Drinking water, are you drinking it right?
Both bottled and bottled water on the market belong to packaged drinking water, and the common packaged drinking water can be roughly divided into three categories: purified water, natural water or natural spring water, and mineral water.
Purified water Purified drinking water is made by processing water that meets the sanitary standards of drinking water by distillation, electrodialysis, ion exchange, reverse osmosis or other appropriate water purification processes. Distilled water in the market is also purified water.
In the process of treatment, pure water removes harmful components such as bacteria, viruses, heavy metal elements and organic matter in the water, the hardness is low, the taste is better, it can be drunk directly, and it will not form scale when boiling water. However, during the treatment process, minerals such as potassium, calcium, and zinc, which are beneficial to humans, are also removed.
Natural Water / Natural Spring Water Both drinking natural water and drinking natural spring water are made from water from natural sources that have not passed through the public water supply system, the difference is that the source of natural water can come from wells, mountain springs, reservoirs, lakes or alpine icebergs, etc., while natural spring water can only come from underground springs. These two types of water require minimal treatment (e.g. filtration, ozone or equivalent) to remove impurities and harmful substances from the water while retaining the minerals and trace elements that are present in the water that are beneficial to humans.
Mineral water What we call mineral water in our daily life mainly refers to drinking natural mineral water. Drinking natural mineral water is water that naturally gushes out of the depths of the underground or is collected by drilling, contains a certain amount of minerals, trace elements or other components, is not polluted in a certain area and takes precautions to avoid pollution; under normal circumstances, its chemical composition, flow rate, water temperature and other dynamic indicators are relatively stable within the fluctuation range of the natural cycle.
Mineral water is essentially natural water, but natural water is not necessarily mineral water. Mineral water must be deep groundwater, and its minerals or carbon dioxide and other components must meet one or more of the limits in the national standard. Generally speaking, mineral water has stable water quality, little microbial content, and contains a certain amount of minerals and trace elements required by the human body, such as zinc, selenium, strontium, etc.
The "purer" of daily water is not always better
From a health point of view, the natural trace elements and minerals in water are valuable nutritional and health resources, so the "purer" water is not the better, and the natural elements that are beneficial to the human body should be retained as much as possible, and the harmful components should be removed.
Scientific studies have shown that moderate amounts of calcium and magnesium in water have a protective effect on cardiovascular health. Although water provides only 2%-4% of the body's magnesium needs, it can still play an important role in those who are mildly deficient, such as those who overexcrete magnesium due to diuretic drugs such as high blood pressure and heart disease. In addition, magnesium in the dissolved ionic state in water is more easily absorbed by the body than magnesium in food. According to the World Health Organization, long-term consumption of mineral-free water can directly or indirectly lead to low or no absorption of beneficial minerals by the body. Therefore, purified water should not be drunk as a single daily drinking water for a long time, and can be drunk occasionally or alternately with other types of drinking water.
Although purified water is not suitable for long-term drinking, in some cases, such as when making tea, it has a unique advantage of not being "impurities". Purified water has a low pH and the least mineral content, and when used to make tea, the soup color is bright and the fragrance is pure, which can best reflect the original taste of various teas.
So the higher the mineral content, the more beneficial it is to human health? The trace elements and minerals in the water may have a certain improvement effect on some chronic diseases, such as digestive tract diseases. However, water with too high mineral content is not suitable for everyone, and in some cases, it is necessary to choose according to your own situation.
Plain water is the most economical and healthy
The most economical and healthy daily drinking water for ordinary people is boiled tap water, that is, boiled water. Tap water is currently the most common drinking water in China, which is taken from the surface or underground natural water source, purified and disinfected through a series of treatment processes and delivered to thousands of households.
The mainland has strict requirements for tap water quality, and tap water that meets the "Sanitary Standard for Drinking Water" (GB 5749-2022) is safe and reliable.
After treatment, tap water removes some of the parts that are harmful to the human body and retains minerals that are beneficial to the human body. However, due to the long distance of the municipal pipeline, in order to avoid microbial contamination during transportation, it is recommended to boil it and drink it.
After boiling tap water, it can not only kill the microorganisms in it, but also effectively remove volatile substances such as residual chlorine and halomethane. Drinking plain water is a good habit that has been passed down from generation to generation by our Chinese. Boiled water is inexpensive, simple to make, convenient and fast, and is the most economical and practical first choice for drinking water to meet human health.
Pay attention to the following points when drinking water correctly
Arrange your daily drinking time wisely
In addition to drinking the right water, it is also important to drink enough water, and it is recommended that adults drink 1500-1700ml of water per day. Drink water according to the principle of "small amounts, many times" and do not wait until you are thirsty. If it's bottled or bottled water, be sure to choose a product that is trustworthy with guaranteed quality. It is best to replenish the missing water 8-10 times a day. It is best to drink water on an empty stomach to be more easily absorbed by the body.
Scientifically judge the water shortage of the body
In the case of high temperature or strong physical labor, in addition to increasing the amount of water supplemented, salt should be replenished at the same time. People can judge whether the body is dehydrated by the color of urine, light yellow means that the water is sufficient, and when it is yellow, it is necessary to increase the amount of water intake.
Special groups should not drink a lot of water
Patients with malignant tumors, lung infections, central nervous system, traumatic brain injury, cerebral hemorrhage, renal failure, heart failure and other diseases should not drink a large amount of water at one time, and the amount of water intake should be adjusted according to the doctor's advice. In general, the total daily water intake of patients with heart failure should not exceed 1500 ml, including food and water, and the total daily water intake of dialysis patients with kidney failure should not exceed 800 ml.
