Since 1980, the EU overturned the requirement that a mineral water 1.000 milligrams of dissolved minerals per liter, even waters that contain only slightly more minerals than the cool water from the tap can be called natural mineral water.
If you consciously pay attention to the mineral content, athletes in particular can compensate for minerals lost through sweating, lactose-intolerant people who drink this water can secure their calcium supply, and varieties with a high sulfate content can relieve constipation.
Depending on how much carbon dioxide has been added, mineral water is labeled "still," "medium" or "sparkling," or "carbonated" or "non-carbonated. By the way, how the mineral water tastes depends on the composition of the mineral substances.
Natural mineral water
Natural mineral water is so called because it is not allowed to be treated by the well companies.

In addition, water activates circulation and metabolism. In a study of normal-weight people, drinking half a liter of room-temperature liquid before breakfast increased caloric expenditure by about 50 calories. Calories were burned to heat the water and boost the body's own heat production. Even on the blood sugar-lowering hormone insulin -. and thus on the risk of diabetes – regular water drinking could have a positive effect. However, this has not yet been scientifically proven.
But drinking water could benefit the skin and blood circulation. Because our largest organ consists for the most part of the liquid element. Stores almost one third of the liquid present in the human body. Drinking water increases blood flow to the skin, red blood cells flow faster. In addition, sufficient hydration improves the oxygen supply to the skin.
Drinking water: How much per day is enough?
Drinking plenty of water is therefore healthy in several respects. How much water per day is sufficient depends on age as well as physical activity. Athletes should drink a little more water because of the sweaty additional movement, seniors are usually less thirsty.
