What water should we drink?
Mineral water
Mineral water – natural healing water that contains min.1000 mg/dm³ of
soluble components in the form of ions. Besides it can contain natual
gas(carbon dioxide or sulfide). In Poland the most popular water that can be
found in shops is confined ground water which received mineral salts from
natural rocks or minerals it was passing by. The first definition of mineral water
was created during the International Balneological Congress in Bad Nauheim
in 1911.
Water selection
How to choose water? The answer is not easy. Despite the fact that water in
bottles looks similar, not every bottled water is for everyone and sometimes
it is necessary to behave like two specialists – a dietician and a detective –
to make a good choice. What information can we find on bottle labels?
Labels- what does a producer
tell us about his product?
Labels on bottles with mineral water should have basic information
necessary for all food products: name of the product, name of the
producer, place of production , address, the expiry date and storage
conditions.
Labels on mineral water bottles should also inform about the level of water
mineralization, the amount of characteristic mineral ingredients and in
case of sparkling mineral water – saturation level with CO2.
Mineral ingredients – healthy
elements to drink
Mineral ingredients of water are well digested by our body. They can
supplement our every day diet. Bottled mineral water contains four times
more of calcium and magnesium than tap water. By drinking mineral water
rich in magnesium people with high blood pressure are able to lower it.
Magnesium helps to lower stress in stressful situations. It is helpful if you
suffer from allergies. Our magnesium needs equal to 300 mg a day. There
are other sources of magnesium, too. Brown rice, almonds or spinach are
good sources of magnesium. Another important ingredient is calcium which
is the essential component of our bones or teeth. Our needs amount to
1000 mg a day.
Drinking water can definitely contribute to intake a lot of minerals such as
calcium or magnesium but it can’t be the only source of minerals.
What is more, mineral water will not supply our body with such important
elements as proteins, amino acids, carbohydrates, vitamins, fats as well as
some important minerals, for example iron, phosphorus or iodine.

Mineralization or how many
minerals in water?
Depending on the general number of minerals in the liter of mineral water
the following classification is used:
-not higher than 50 mg/l – very low mineralized
-not higher than 500 mg/l – low mineralized
-
-from 500 to 1500 mg/l – medium mineralized
-
- over1500 mg/l – high mineralized

Toxic ingredients-what should
we avoid?
Nitrites and nitrates. They indicate impurities that come from plant protection substance and
organic substances. Nitrates are not very harmful but they can change into toxic nitrites. They
can also block or even damage vitamins.
Fluorine. Although fluorine is the essential component of bones, in large amounts can be
toxic. Low amounts of fluorine causes teeth decay and osteoporosis.
Uranium. It is a radioactive metal. Its occurrence in drinking water is not connected with its
radioactive features but with its chemical features. If we drink water with high level of uranium
for a long time, it can damage our kidneys.
