The WHO in 1980 prescribed a limit value of 50 mg / l per day for ingesting nitrate. Nitrate is ingested through food or drinking water and harmless for adults without any intestinal intolerances, when observing the recommended level.
Function & Details
Nitrates are formed in the ground and in waters. Vegetable organisms use nitrate as a source of nitrogen, and the surplus which is not absorbed accumulates in the ground and is flushed out again with the rain or snowmelt into the lower soil layers and groundwater.
The reason for health risks lies in the danger of the nitrate being reduced to nitrogen and the formation of carcinogenic nitrosamines. Such a transformation is generated by corresponding bacteria in the gut on the one hand, on the other hand the salivary glands can also reduce the washed-up nitrate through the blood. Low-nitrate mineral water is recommended for preparing baby and infant food, as otherwise they may suffer from poor oxygen supply in the body and cyanosis.
As opposed to this, though, nitrates are also used in medicine, such as for producing a drug for vascular dilation, as nitrate is an efficient oxygen provider.
Compared to tap water which, as mentioned above, must not exceed a recommended value of 50 mg / l, mineral water boasts very low nitrate values which are well below the limit for tap water. In addition, mineral water is protected from environmental influences such as fertilisers and light, as the springs are all located deep below the soil and are subject to regular testing.
We recommend mineral water which can be declared as baby mineral water thanks to its low nitrate content for preparing baby food. According to the Austrian Beverage Institute A-1180 Vienna, Frankenmarkter mineral water in particular meets all requirements for preparing infant food thanks to its balanced minerals and particularly low nitrate levels.
