NutritionFacts.org – Magnesium-Rich Foods to Prevent Sudden Death.
Our story begins 43 years ago with a fascinating paper in the New England Journal of Medicine entitled, “Sudden Death and Ischemic Heart Disease: Correlation With Hardness of the Local Water Supply.” There appeared to be “an increased susceptibility to lethal arrhythmias [fatal heart rhythms] among residents of soft-water areas.” So maybe one of the minerals found in hard water is protective, but which one? Well, researchers decided to cut some hearts open and find out.
On autopsy the hearts of sudden cardiac death victims had significantly lower magnesium concentrations compared to people that just got hit by a bus or something. They thought there might be a connection, but it wasn’t put to the test until recently.
