Some people believe that drinking pure water for a long time is harmful to the body, and mineral water is better than pure water.
In fact, this is a complete rumor, and there is no scientific basis for the claim that "drinking pure water is harmful to the body."
Drinking pure water will cause the loss of calcium and other elements in the body, resulting in imbalance of electrolytes in the body, or breaking the body's acid-base balance. These remarks are all nonsense. At present, there is no evidence to prove that pure water is harmful to the human body.
The difference between pure water and mineral water is mainly because mineral water is rich in a variety of minerals, and there is no difference between the two.
Some people think that we need to supplement these trace elements through mineral-rich water. In fact, the human body mainly replenishes minerals or trace elements through diet. Drinking water mainly aims to replenish water, and there are not many minerals rich in water at all.
The six major nutrients required by the human body include water, inorganic salts (inorganic salts are minerals), protein , sugars, vitamins and lipids. In daily life, these nutrients can be supplemented by staple foods such as grains, meat, milk, eggs, fruits and vegetables. Even if there is no mineral in the water, it will not have much impact, because this is not the main way for us to obtain minerals.
As long as we are not picky about food and keep it rich in nutrients, our body will usually not lack minerals. Why bother to replenish it by drinking water. There is no shortage of nutrition, there is no need to over-replenish it! This nutritional anxiety is largely due to the manufacturer's overwhelming publicity, which has subtly misled many people, making people think that they are very short of minerals and need to drink mineral water for additional supplements.
Some of the salts sold on the market that are added with various minerals are also used in this routine. I dare to ask how much salt you can eat every day. Can you really replenish minerals? Of course, for the trace minerals that people generally lack, you can replenish them in this way.
Some people also think mountain spring water is good because it is rich in various minerals. However, some mountain spring water contains heavy metals and other harmful substances that are invisible to the naked eye, which is far less than purified water after filtering.
For the purity of water, we usually measure it by the TDS value, which represents the total amount of soluble solids in water (including inorganic and organic matter) in milligrams/liter (mg/L). Generally, the higher the TDS value, the more dissolved substances are contained in the water, and the more scale it produces when boiling water.
filters water not only to remove harmful substances such as bacteria and heavy metals in the water, but also to reduce the hardness of water , that is, to remove excessive minerals and other solid dissolved substances in the water.
The drinking water filters currently sold on the market only have nano-level filtration functions that can reduce the TDS value of water.
However, no matter how good the filter is, it is impossible to change the TDS value of water to 0. Even the water filtered by the RO reverse osmosis membrane water purifier, or the bottled water sold on the market, or the distilled water in the laboratory, cannot reach 100% pure.
Usually water with a TDS value of less than 50 can be consumed directly. This kind of water does not need to boil it! The reason why we have to boil and drink in traditional life is that there was no reverse osmosis filtration technology before, and water needs to be sterilized.
There is no problem that the filtered water will boil repeatedly, which will produce harmful substances (such as nitrite ). In fact, it is nonsense to talk about dosage and toxicity. thousand boiling water you dare not drink it. How dare you drink it after boiling the soup for several hours?
We call water with a higher TDS value, such as 300 mg per liter, we call it hard water . This water contains a lot of minerals, such as calcium, magnesium, etc. However, this harder water is not good to drink and is not suitable for drinking.
The mineral water sold on the market is not as high-end. It is said that the water source is directly filled, but it is actually filtered, and some minerals are also added later. If you directly fill the natural water in nature, no matter whether you are Changbai Mountain or where you are, the filtration rate will exceed the standard and the quality inspection will not be passed, so you will have been removed from the shelves long ago.
After all, drinking pure water for a long time is not harmful, and drinking mineral water is not very beneficial. There is no difference between mineral water and pure water.
