The Hard link between Drinking water & cardiovascular disease

Bottled Water Contaminants

He concluded "some factor either present in hard water, or missing or entering in soft water is associated with higher death rates from degenerative cardiovascular disease." In 1979 after reviewing fifty studies, Corn stock concluded, "there can be little doubt that the associations of water hardness with cardiovascular mortality are not spurious. Too many studies have reported statistically significant correlations to make chance or sampling errors a likely explanation." He suggests that the reason for this association is due to a "deficiency of an essential element or an excess of a toxic one." Certainly a combination of both is also possible.

Today after thirty years of research we are left with Schroeder's initial conclusion-drinking hard water results in less cardiovascular disease than drinking soft water. Yet over the years there have been several published reports analyzing specific elements in drinking water and their possible relationship to heart disease. One researcher studies zinc, another copper; another selenium, and so on. And as you read this material, you find an inconsistent and confusing picture. But, if you look at the broader picture, if you look at the studies on hardness, you will find very consistent results: namely, the harder the water the less heart disease deaths.

Before highlighting some of the major studies let's discuss TDS, total dissolved solids. TDS is a measurement of all the minerals in drinking water TDS not only includes calcium and magnesium (the hardness factors), but also zinc, copper chromium, selenium and so on. Sauer analyzed 23 drinking water characteristics in 92 cities ("Relationship of Water to the Risk of Dying") and found people who drank water higher in TDS had lower death rates from heart disease, cancer and chronic diseases than people who drank water with low amounts of TDS. Frequently, where the water is hard the water is also high in TDS.

Although most studies on heart disease have not looked at TDS but at hardness, this factor has been ever present and may be playing a very significant role. The more we try to isolate and study the effects of individual minerals the more we can lose sight of the unifying, comprehensive, beneficial factors present in water like hardness, TDS, and pH. Perhaps one of the main reasons there are inconsistencies in the water story is simply because we are obsessed to locate a specific isolated element that is responsible for the beneficial effects of healthy drinking water. Lets look at some of the major studies. In Great Britain, the British Regional Heat Study analyzed 253 towns from 1969 to 1973. They found 10% to 15% more cardiovascular deaths in soft water areas than in hard water areas. They suggest that the ideal amount of hardness is approximately 170 mg/L (or ppm-parts per million).
