Is there any health benefit to hard water, given its higher mineral content?
Years ago it was postulated that hard water did give advantages over soft water in prevention of bone disorders, heart disease, tooth decay and possibly kidney complications, but I know of no large controlled trials or surveys that convincingly show that people in hard-water areas have less illness or survive longer. I’m very willing to be disproved, however. We live in a hard-water area, and have a high heart disease incidence; we used to live in a soft-water area with low levels of heart disease. The reason for that difference almost certainly lies in social and economic circumstances, and in eating habits, rather than in the water. ยท Do you have a question for Dr Smith?
