Soft water increases cardiac morbidity because water is the most important source of calcium and in the deficiency of vegetables, nuts etc. of magnesium as well

Thanks a lot for your answer Olga. In my country the total hardness of the water to supply the population is > 200 mg/L with low concentration of magnesium. How can you explain that? The population usually consume food poor in energy. is not a risk for the population with low concentration of magnesium in drinking water?

The dietary and water magnesium intake is to be 300 -700 mg total per day. The hot climate moves this to the higher estimate. Women need more magnesium. Perhaps Haiti people like they in Spanish America do not consume cocoa without sugar, raw bananas, green vegetables, leaves, fish etc. Food poor in energy means food poor in magnesium as well usually. Stress because of such a food and stress in general cause magnesium deficiency. Sugar causes/increases the deficiency of magnesium. We will have the master's program in "Occupational heath, safety and environment engineering management" suitable to train your country engineers responsible for water supply as well next year. Please send me your e-mail address to deliver details to you.

...or the kidneys!!!???

Thank you very much Olga. This is my e-mail: [email protected]

what do you mean Fonseca? I am not so clear.

For the kidney question, kidney stones can develop due to low fluid intake, diets rich in calcium, magnesium and hard water concentrate in the kidney, calcifies into crystals called kidney stones, bladder stones are not left out.

Thank you Chinyere for your answer. Can you explain to me the physiopathology please? I know there is relationship between water hardness and urolithiasis. I would like to have more details. How urolithiasis can be developed by water hardness?
