Health News: Do you know the acidity and alkalinity of water?
Water is water, it quenches thirst, and there is no other use......"Ten years ago, or even five years ago, someone might have said that. Now, the importance of drinking water to the human body has been recognized by more and more Chinese people, however, in the current disturbed drinking water market, how to choose a safe and healthy drinking water has become a real priority.
With the improvement of modern people's requirements for quality of life, more and more people have joined the fixed consumer group of packaged drinking water. Indeed, bottled water and bottled water on the market often give people a sense of trust: water that people put so much effort into bottles and sell hundreds of times more expensive than tap water should always be a good thing.
What's more, the water looks crystal clear, without a trace of impurities.
You might say with a little pride: I drink packaged water at home. But if you are asked whether you drink acidic or alkaline water, do you know the answer?
In fact, the things you take for granted in life may be the ones you don't know the most. Two bottles of water that look exactly the same, the difference between them can be as many as 108,000 miles. Before choosing to buy packaged drinking water, it's a good idea to have a little understanding of the "sex" of water
Anyone with a little knowledge of chemistry knows the concept of pH. The pH value is commonly known as pH, which is divided into 14 grades from 1 to 14, 1-7 is acidic, 7-14 is alkaline, and 7 is neutral. One of the fundamental factors that determine the "nature" of water is the pH value of water.
According to the size of the pH value, the drinking water on the market can be divided into two types: weakly acidic water and weakly alkaline water. The pH of the former is generally in between, and the pH of the latter is generally in between.
When choosing daily drinking water, we should also choose weakly alkaline water. For water, whether the water contains minerals and trace elements is the key to determining its acidity and alkalinity. Water in nature, such as spring water, lake water, etc., is generally weakly alkaline because nature has endowed it with abundant minerals and trace elements.
Whereas, pure water, as the name suggests, has nothing but water molecules in it, and the water nature is naturally acidic. The artificial mineral water that is now popular on the market has destroyed the acid-base balance of the water due to the artificial addition of minerals, and is even more acidic than pure water.

The human body is a relatively stable and weak internal environment. The pH (acidity) of normal people's blood should be around the same level. The same is true for water, most of the original natural good water is weak.
But tests on mineral water have found that its pH is below and even more acidic than purified water. In recent years, many experts and authoritative institutions have suggested that the human body should not drink pure water for a long time, because it does not contain banquet minerals at all. Therefore, this summer, mineral water is particularly popular with the people.
However, nutrition experts remind that mineral water is artificially added minerals on the basis of pure water, and the pH value of this artificial mineral water is mostly acidic, which cannot restore the water to a weak and healthy state.
Modern medicine has proved that the human body is a relatively stable and weak internal environment. The pH (acidity) of normal people's blood should be around the same level.
The same is true for water, most of the original natural good water is weak, containing potassium, calcium, sodium, magnesium and metasilicic acid and other natural minerals that are beneficial to the human body, pure auspicious, and can match the needs of the human body. But tests on mineral water have found that its pH is below and even more acidic than purified water.
The acidity of water is determined by the ions contained in the water, and pure water removes all mineral cations, so it is more acidic. At present, the production process of mineral water is to artificially add acidic mineralized liquid containing potassium chloride and magnesium sulfate to pure water, and these acidic artificial mineralized liquids are decomposed in water to produce a large number of chloride ions and sulfate ions, which makes it less acidic. In addition, the properties of potassium and magnesium ions that are artificially decomposed are not stable, so they cannot be absorbed by the body's cells as effectively as the natural minerals in water.

Mineral water is unpolluted underground mineral water that springs naturally from deep underground or is artificially exposed; Contains a certain amount of mineral salts, trace elements or carbon dioxide gas; Under normal circumstances, its chemical composition, flow rate, water temperature and other dynamics are relatively stable within the natural fluctuation range. Mineral water is formed by circulation in the deep stratum and contains minerals and limited indicators specified in national standards. According to the difference in physical condition and regional drinking water, choosing the right mineral water to drink can play a role in replenishing minerals, especially trace elements. >>>More
Minerals have a great impact on plants, plants need about 25 kinds of elements, c h o n p s na mg al b mo ca fe zn and so on, minerals mostly have these elements, they are absorbed by the roots in the soil, transported to different parts of the plant, and act, many plants lack minerals and leaves will turn yellow, For example, if there is no mg, you can't carry out photosynthesis normally, because mg is a necessary element for the synthesis of chlorophyll, etc., if you want to understand more deeply, You can look up every element.

Minerals are a class of micronutrients that are essential for the human body, including macroelements and trace elements. Minerals are found in almost every part of the body and play a variety of roles.
Lack of minerals in the body can lead to weakness, vision loss, poor sleep, cognitive decline, and low body resistance. >>>More
