Tap water is an excellent thirst quencher - even without filter systems

Drinking water quality in Germany is excellent even without filter systems

Water is vital for the human body - those who drink too little endanger their health. Mineral water is one of the Germans' favorite drinks, but tap water is usually just as good in this country. You can safely do without water filter systems. According to experts, this cannot improve drinking water quality at all.

Insufficient fluid intake is unhealthy

If a person drinks too little, the fluid balance becomes unbalanced. That endangers health. It is known, for example, that fluid loss can lead to physical and mental complaints. "If you drink too little, you can get a headache or circulatory problems," explains Theresia Weimar-Ehl, nutrition expert at the Saarland consumer center, in a message. In addition, complaints such as difficulty concentrating, dry mouth, tiredness or constipation appear in those affected. So there is no question that the human body needs enough fluid to stay healthy. But how much water should you drink every day? And which one?

Tap water is as good as mineral water

According to Weimar-Ehl, drinking one and a half liters evenly throughout the day is usually sufficient under normal conditions.

Other experts prefer two to three liters a day.

And especially in high heat, experts should drink at least an additional liter of water.

Tap water is a very good thirst quench because it is checked regularly and is inexpensive to buy almost everywhere. In many regions it is as good as mineral water.

This was also confirmed in an older test by the Stiftung Warentest. At that time, the testers examined still mineral water.

The mineral content is often not higher

According to the consumer center of the Saarland, there are a number of mineral waters, medicinal waters and spring and table waters in Germany, all of which are suitable as thirst quenchers except for a few medicinal waters.

According to the experts, natural mineral water is the only food that has to be officially recognized and approved for distribution. The requirements for spring water are therefore somewhat lower than for natural mineral water.

Table water sounds noble, but is mixed together from tap, mineral water and various ingredients.

“Which water you choose to quench your thirst is up to your personal taste,” says Weimar-Ehl.

“Mineral water often has no higher mineral and trace element content than drinking water. A varied diet provides you with all the nutrients you need, ”explains the nutrition expert.

"The price is not an indication of the quality of mineral water, but depends on the marketing strategy of the provider. Drinking water from the tap is cheaper, more convenient and safer. ”

No improvement in quality

If you rely on tap water, you can confidently do without filter systems that are often advertised by suppliers as pure and healthy drinking water.

In reality, such systems can even deteriorate the quality of tap water if used incorrectly, the consumer center in Schleswig-Holstein writes in a message.

The Kiel Health Department confirmed this on request.

The improvement of drinking water quality by water filters and filter systems for the household could not be proven.

Rather, some filter systems run the risk of germs multiplying in them if used incorrectly.

False claims by providers

According to consumer advocates, some supporters of filter systems reinterpret valuable minerals such as magnesium or calcium as polluting substances.

"Such claims are wrong," says Gudrun Köster, food and nutrition expert at the consumer advice center.

"The minerals from the drinking water can be easily used by the body and are important for health, since they have important functions in bone building and energy metabolism," said the expert.

"Anyone who only drinks extra filtered water without minerals in the long term risks an undersupply and deficiency symptoms." (Ad)
