Drink More Tap Water!

Tap water may taste different from region to region, but it does not necessarily have anything to do with its quality. Differences in taste occur if the water has been specially treated, for example with chlorine. Stadtwerke Düsseldorf, for example, disinfected its water with chlorine dioxide until two years ago. Among other things, this counteracted faecal germs, but the fine chlorine note could also be tasted.

The so-called water hardness can influence the taste, especially of hot drinks. The aromas of tea and coffee are said to emerge better if they have been prepared with soft water. Hard water is water that is particularly rich in magnesium and calcium. When it rains, the substances are washed out of the rock and get into the groundwater. Depending on the type and composition of the rock layers, sometimes more, sometimes less.

Distilled water does not kill

Hard water leaves the well-known lime residues on tiles and fittings. Household appliances such as dishwashers or washing machines can be damaged by the deposits. However, hard water is not harmful to health at all: magnesium and calcium are important trace elements that are responsible for healthy nervous performance. Magnesium also plays an important role in several metabolic processes, calcium helps build bones and teeth and contributes to blood clotting. Other ingredients in water that are important for the body are sodium, potassium, iron and zinc.

However, humans do not consume these elements mainly through drinks, but obtain them mainly from solid food. Mineral-poor water therefore does not usually lead to deficiencies. Some people even drink only distilled water and cope with it. That this is supposed to be deadly is a legend. Nevertheless, the electrolyte balance can get confused if you drink only water without minerals. Therefore it is advisable to drink mineral or tap water.

Which of the two waters contains more minerals cannot be said in general. A study by Stiftung Warentest has shown that even natural mineral water can sometimes be poor in these substances.

Table water is not mineral water

For a water to be called mineral water, it must be bottled directly at a spring that is fed from underground water sources. Anyone who wants to drink natural mineral water does not have to resort to varieties from the French Alps or the northern Italian provinces. There are numerous springs in Germany. The Federal Office for Consumer Protection and Food Safety has compiled a detailed list.

The decisive factor for the title “natural mineral water” is that its ingredients may hardly be changed. In contrast to table water, which is actually only tap water, from which all minerals have first been removed and then certain quantities of substances have been added again. This means that table water can be bottled anywhere and still always tastes the same.
