How much water we should drink ?

The human body is known, two-thirds consists of water. Particularly rich in water young body tissue. With age, its size gradually decreases: for example, the body of the fetus in three – 95 percent of water, five months – 85 new-born child – 70 and older – about 65 percent. In this regard, one of the reasons scientists believe aging, reducing the ability of colloidal substances in the body, especially proteins, to bind large amounts of water. It is no secret that without food one person can live more than a week without water die within a few days. It has long been known that doctors’ recommendations that people should drink a day for at least two liters of fluid. However, in the early twentieth century, when this information, it is more about water. Currently, those who prefer to quench their thirst with water becomes less. Most people drink sodas and juices. But recently scientists from the University of North Carolina have made a surprising discovery. As experts say, calories are not easily absorbed by the body of solids, namely of drinks.

Moreover, high-calorie drinks, there is one side effect: they make us eat more.
Should we drink water during meals – this is none of perspective. Some believe it is advisable to drink cold water, almost every meal, while others say it is not necessary because the water dilutes digestive juices and significantly impairs digestion. Drinking water is recommended only before meals, in the case of thirst. In an empty stomach water is retained and does not distort the processes of digestion. Packaging, on the contrary, it is late, diluting its content slows digestion. The daily need for water is determined by environmental conditions, nature of work, number of meals. Excessive consumption of water also has undeniable harm as it encourages excessive load on the heart and to accelerate the disintegration of the protein.
