Hard Water

Q. Does the body appropriate for bones and teeth the lime or calcium carbonate from ordinary hard water?

A. We know of no evidence that the mineral constituents of hard water can serve as food or nutriment to the body. In the foodstuffs the lime exists in an organized form in which it is prepared for assimilation. The lime found in hard water is an ordinary inorganic mineral compound. The best sources of lime are oat­meal, graham bread, bran, milk and vegetables, especially "greens." Potatoes, sugar, rice, fine flour bread, meats, butter, lard and other fats, contain practically no lime. Milk and bran are very rich in lime, also turnip "greens" and spin­ach. These same foods are rich in iron. Lime and iron are usually associated in foodstuffs.
