Purified water is prepared through processes such as reverse osmosis, ion exchange, and distillation, removing the vast majority of impurities. This water is clean enough and very safe for drinking. But it is often said that pure water lacks trace elements, and long-term consumption can lead to nutritional deficiencies and harm health. Really?
Drinking water, just to replenish the water
Some people say that pure water removes impurities and minerals that the human body needs!
That's right, pure water has almost no minerals. However, drinking water is to meet the body's water needs. The three meals we eat a day are the main way to obtain these nutrients. You should know that the mineral content in drinking water is very low, and it is not as divine as advertised in mineral water advertisements.
You can take a look at the indicators of mineral water sold on the market, such as the calcium content. If you calculate the calcium content of a bottle of water, it's not as much as the calcium in a sip of milk. The true meaning of wanting to supplement minerals by drinking water is not significant.
If someone tries to deceive people with the phrase 'pure water leads to nutritional deficiency' in the future, do you just give them the answer: there is no vitamin C in rice, so eating rice can also harm health?
The rumors about pure water
There are too many "black pots" on pure water, so choose a few that are the most widely circulated to come out and face it.
1. Pure water is acidic and the source of all diseases?
The saying 'acid-base constitution' is simply the biggest health rumor of the 21st century, which has been destroying people tirelessly for so many years. Both weakly acidic and weakly alkaline water is acidic in the stomach (due to gastric acid), and weakly alkaline in the intestine. The pH value of human blood and body fluid is controlled by a set of Dynamic equilibrium metabolic mechanism to keep the pH value in blood at a stable value. Can a bottle of water affect it?
2. Will pure water take away useful minerals from the body?
This rumor is that pure water removes substances from the water, but water has memory. Therefore, water enters the human body and discovers that all trace elements deprived of it are present in your body. Therefore, water metabolizes minerals such as calcium, zinc, and magnesium in your body. That is to say, drinking purified water leads to a decrease in calcium intake.
Our emotions were shocked to see such a divine copy. In the production of pure water, heavy metals and harmful substances are also filtered out. According to this logic, can drinking pure water also detoxify and treat diseases?
In fact, the human body is constantly undergoing metabolism, excreting metabolic waste, and absorbing new nutrients. And among these metabolic waste, there are many trace elements. So, whether you drink pure water or not, the trace elements in our bodies are constantly metabolized, which is not a scary thing. The body has its own ion balance mechanism. As long as you have a Healthy diet, the trace elements metabolized can also be supplemented by food.
3. Do developed countries not drink purified water?
The rumors nowadays are so daring to say anything. You can go to the website of Wal Mart in the United States to search for "purified water", and there are more than 30000 results! The fact is that Europe and America have been drinking purified water for decades, and no correlation has been found between purified water and any diseases.
Behind these rumors, there is likely to be a commercial purpose. Those who deceive you that pure water is not good often hope that you buy mineral water, weakly alkaline water, or other water related products.
What water should we drink?
For drinking water, the most important thing is safety. So, there is no problem with qualified purified water, mineral water, or plain water. What is convenient (cheap) to choose.
As for the high-end water that is often priced at tens of yuan or tens of yuan on the market now, such as "glacier water", "plasma water", "ecological water", and "deep ocean water", it is basically "form outweighs content", and the content of trace elements may be slightly higher, but it is far from comparable to daily diet.
