Pure water, mineral water, distilled water and straight drinking water, each claiming to be good for health, which one is better to drink?
1. Distilled water
It is made by distillation or other multi-layer filtration process, which removes harmful substances and microorganisms, but also removes potassium, calcium, magnesium, and other minerals that the human body needs.
Additionally, there are risks involved in this seemingly rigorous production process. Tap water contains cyanide and volatile phenols, which are easily volatilized, and production by distillation concentrates the content of these two substances. In the process of distillation, if the method is not careful, there may be risks.
For people with kidney stones, mineral-free distilled water is a good choice, but for healthy people, drinking too much distilled water is not recommended.
Summary in one sentence:
No minerals, but possibly cyanide and volatile phenols.
2. Drinking water
Drinking water, that is, drinking water or water that meets the health standards for drinking water as a source of water, after the initial filtration, fine filtration, as well as reverse osmosis filtration, sterilization, and other purification of purified water available for direct consumption.
Through the direct drinking water equipment filtration, the water of toxic and harmful heavy metals, most of the organic pollution will be removed, but impurities are removed at the same time, about 90% of the trace elements in the water will be filtered out.
There are several levels of pre-filters installed at the front end of various water purifiers, commonly PP cotton filters, activated carbon filters and so on. Water filtered through the home water purifier is generally very good for the first few weeks of water purification, but the worse the water quality of the place of secondary pollution is more serious, if three months before the change, it really becomes a dirty water, it is recommended that 1 ~ 3 months to replace the pp cotton and activated carbon.
Summary in one sentence:
Can be drunk directly, but the filtration process is easily polluted.
3. Pure water
Pure water is made from water that meets the hygienic standards for drinking water, and is made through ion exchange, reverse osmosis and other production processes. On the one hand, it filters out the harmful substances in the water, and on the other hand, it also filters out the minerals and trace elements that are beneficial to the human body.
Low ion content, low water hardness, almost no minerals, with which to boil water will not form scale, but long-term drinking may cause a lack of trace elements, reduce the body's immunity, increase the risk of cardiovascular disease.
It is important to note that people who exercise a lot and sweat a lot, such as athletes and steelmakers, should not drink a lot of pure water because they can't consume many trace elements from it.
Summary:
Clean but lack of nutrients, not recommended for long-term drinking.
4. Mineral water
From the depths of the ground naturally gushing or drilling collection, by the bottom of the perennial filtration, purification and activation, rich in minerals, the human body absorption rate is high.
Because mineral water contains more minerals, excessive drinking will make these mineral salts stimulate the kidneys and bladder, increasing the burden on the kidneys and bladder. So patients suffering from chronic nephritis, high blood pressure, heart disease and patients with swelling should not drink mineral water for a long time.
Summary in one sentence:
Mineral rich, but some people should not drink.
5. Boiled water
From a health point of view, boiled water is currently considered the most human needs of drinking water, clean and sterile, boiled, water quality and water hardness is improved, preserving the right amount of minerals, is the most economical health drinks. It does not contain calories and can be directly absorbed and utilized by the body without digestion.
Summary in one sentence:
The safest and most secure, five-star recommendation!
Summary
1. Normal people are better off drinking plain water and mineral water on a daily basis.
Mineral water contains minerals that the human body needs to replenish the body's needs, more suitable for normal people than pure water. The white water is easy to enter the cells through the cell membrane, promote the body's metabolism, enhance the body's immune function, improve the body's ability to resist disease, is the most in line with the needs of the human body drinking water.
2. Do not drink the same type of water for a long time, especially pure water.
People of different ages should drink water with different mineral contents. For example, water containing metasilicic acid is better for the cardiovascular of the elderly, while it is not suitable for children. Kidney stone patients, on the other hand, are advised to choose mineral-free purified or distilled water as well.
Tips on drinking water
1. Don't replace water with beverages
Especially for children, obesity, and people with underlying medical conditions, it's not good for your health. Natural beverages such as tea and coffee can replace water to a certain extent, but it depends on the person.
2. Let the chlorine evaporate first after the water is boiled
Tap water is chlorinated and disinfected, in which chlorine is combined with residual organic matter in the water to produce halogenated hydrocarbons, chloroform, and many other compounds. After the water boils, you can open the lid, turn off the small fire to continue to burn 2 to 3 minutes, which can promote the tap water in the "residual chlorine" and some harmful substances evaporate.
3. Drinking fountains should be cleaned and disinfected regularly
Drinking bottled water should pay attention to the problem of secondary pollution, drinking fountains need to be cleaned and disinfected regularly, if you think it's troublesome to clean, you can buy a pressure pump, directly to the bucket of water pressure out to drink, and as soon as possible to drink the water after the opening.
4. The water in the pipe in the morning do not burn directly to drink
Morning, the water in the pipe to put a period of time before you can boil water to drink. When choosing a faucet, pay attention to the problem of excessive lead. Copper faucet lead exceeding the standard is more likely to some, the best choice of stainless steel.
