Water is the source of all things, whether it is people, animals or plants, can grow rapidly under the moisture of water. Due to the industrial development in recent years, water has become a substance that people are worried about, such as the rumor that "drinking pure water for a long time is easy to lack trace elements and damage health" for decades.
Some people think that this is a simple commercial demeaning, and some people think that it is the truth, which statement is true?
Can pure water still be drunk now?
In fact, the people are also worried about the truth, with the improvement of material life, more and more people began to pay attention to physical health, coupled with a variety of uneven water resources, but also to face heavy metals, toxins, bacteria and other pollution, may cause water pollution.
Even if the tap water is treated with residual chlorine, that is, it is shipped out of the factory in accordance with national standards, that is, the residual chlorine content is greater than or equal to 0.3mg/L.
After the disinfection treatment, in order to add a layer of insurance, it also needs to be completely boiled, so that it can be said to be safe. For pure water, compared with other waters, that is, through distillation, reverse osmosis, ion exchange, etc., the finally produced water is also safe enough to be removed from a large number of impurities.
But some people have grasped this handle, thinking that pure water removes impurities and does not have the minerals needed by the human body, indicating that the loss of the substances needed by the body will be malnourished for a long time, but drinking mineral water is the healthiest.
There are more exaggerated claims, many people also think that people who regularly drink pure water will metabolize calcium, magnesium, phosphorus, iron and so on more quickly.
All in all, these claims are unfounded, but in fact, people do not need to obtain nutrients from water, and even if they have these ingredients, they are far from meeting the needs of the body, let alone the best source of nutritional supplementation.
A more direct way than water is food, such as fresh fruits and vegetables, whole grains, nuts, eggs, milk, etc., which can avoid malnutrition on the basis of a balanced diet.
In addition, like many families want to filter according to the water purifier, in fact, they are similar to pure water, in order to remove harmful substances, it is also easy to filter out residual nutrients. Moreover, people in Europe and the United States like to drink pure water and there is no malnutrition, so everyone can correctly look at it. In terms of nutritional value, it is not worse than the role of boiled water, and it can meet the needs of the body.
According to the physiological structure, the human body has 60 to 70% of the water, according to the needs of the new version of the "Dietary Guidelines for Chinese Residents", the amount of water per person per day should reach 1500 ~ 1700ml, almost 7 to 8 cups of water, so as to ensure the moisture of the skin. For what kind of water to choose, pure water, boiled water, mineral water, tea are healthy water resources, and it is enough to drink in moderation.
