Rumor has it that water that has been boiled several times or for a long time produces harmful substances.
According to internet sources, nitrate, fluoride, or even arsenic can form in water that has been boiled twice.
Dr. Didier Perret, CEO of Chimiscope at the University of Geneva, called these arguments ridiculous, writes Migros .
On the contrary, he even advises boiling water twice to make it suitable for drinking.
Perret stated that boiling water for 1-2 minutes destroys all microorganisms present.
The doctor added that boiling the liquid one or more times will lead to the same result - the composition of the water will not change.
Perret added that there is no risk to a person when drinking water that has been brought to a boil several times.
He also reminded that a well-maintained, scale-free kettle guarantees optimal quality of tea and coffee.
