However, your title is exaggerated.

the water in poland does not have fluoride in it. Children in this country have black teeth because parents put juice in bottles causing "bottle rot" in the teeth. In Canada it is recommended not to give juice until 1 year old and out of a cup- in Poland they have juice from day one.

Also, there is an iodine deficency in the soil. What this means is that vegetables and fruits and other products such as beef that are raised using soil/ grass have less iodine than other parts of the world- I have to take iodine supplements.

People don't typically drink tap water here anyway, unless it is boiled in coffee or tea.
