Hydration optimization: How to identify and choose the most health-beneficial water before routine consumption

We should drink at least 1.5 liters of fluid every day to prevent dangerous dehydration, especially on hot days. It is best to drink water, but not everyone likes its taste. So we often choose flavored water, which is filled with a number of preservatives instead of mineral ingredients. In a glass of flavoured water we can find as many as 2 teaspoons of sugar! In addition to this sodium benzoate (E211), which keeps water in the body, it can also cause allergic reactions and problems with the food system, and when added to water with C salt can be a carcinogen.
