Someone left a message asking:
It is said that pure water lacks trace elements. Long-term drinking will lead to nutritional deficiency and damage health. Is this really the case?
It seems that pure water has to be said.
Drink water just to replenish water.
Pure water is prepared by reverse osmosis, ion exchange, distillation and other processes to remove most impurities. This kind of water is clean enough and is very safe drinking water.
Some people say:
Pure water removes impurities and minerals needed by human body.
Yes, there are almost no minerals in pure water.
However, drinking water is to meet the body’s demand for water. The three meals we eat a day are the main way to obtain these nutrients.
You know, the mineral content in drinking water is very small, which is really not as fantastic as the mineral water advertisement says.
For example:
The author has a bottle of mineral water from a well-known brand:
Calcium content: ≥ 400 ug/100 mL (4 mg/L)
If you drink 2L of water (about 4 bottles) per day, you will only drink 4 mg/L * 2L = 8 mg of calcium, accounting for 1% of the recommended daily calcium intake (800 mg), which is not as much as the calcium in a mouthful of milk.
It is really meaningless to drink water to supplement minerals.
In the future, if anyone deceives people with [pure water leads to lack of nutrition], you will give it back to him like this:
There is no vitamin C in rice, so eating rice can also harm your health?
Rumors of pure water
There are too many [blames] on purified water, so choose some of the most widely circulated ones to hit the face.
1. Pure water is acidic and is the source of all diseases?
Pure water is acidic, drinking too much will make the constitution sour, and acidic constitution is the source of all diseases.
[Acid and Alkali Constitution] It is simply the biggest health rumor in the 21st century. It has been ruining people for so many years.
Whether it is weak acid or weak alkaline water, it is acidic in the stomach (thanks to gastric acid) and weak alkaline in the intestine.
The pH values of human blood and body fluids are controlled by a set of dynamic and balanced metabolic mechanisms to keep the pH values in blood at a stable value.
Is it a bottle of water that can affect it?
2. Pure water will take away useful minerals from the body?
Pure water removes substances from the water, but water has a memory, so water comes to the human body and finds that all the trace elements deprived are in your body, so water metabolizes minerals such as calcium, zinc and magnesium in your body. In other words, the more you drink pure water, the less calcium you lack.
The author was shocked to see such a divine copy.
In the production of purified water, heavy metals and harmful substances are also filtered out. According to this logic, wouldn’t drinking purified water also detoxify and cure diseases?
In fact, the human body is carrying out metabolism all the time, discharging metabolic waste and absorbing new nutrients. There are many trace elements in these metabolic wastes.
Therefore, whether you drink pure water or not, the trace elements in our body are constantly metabolized, which is not a terrible thing in what. The body has its own ion balance mechanism. As long as you eat a balanced diet, the metabolized trace elements can also be supplemented by food.
3. Developed countries do not drink pure water?
Now the rumor is really what dare to say.
Looking at the data from Wal-Mart’s website in the United States, searching for [purified water] has more than 30,000 results:
The fact is that Europe and the United States have been drinking purified water for decades and have not found any correlation between purified water and what.
Behind these rumors, there is likely to be a commercial purpose. Those who fool you into bad pure water often want you to buy mineral water, alkalescent water, or other water-related products.
Should we drink what water?
For drinking water, the most important thing is safety.
Therefore, qualified purified water, mineral water and plain boiled water are no problem. What is convenient (cheap) which one to choose.
As for the high-end water on the market, such as [glacier water] [plasma water] [ecological water] [deep ocean water], which costs more than ten yuan and tens of yuan at every turn, it is basically [form is greater than content], and the content of trace elements may be slightly higher, but it is far from being compared with daily diet.
Of course, these high-end water packages are beautiful, taste is not bad, and they are also hard to hold in your hands. If your wallet does not feel distressed, of course you can buy them. It is good for you to be happy ~
