Magnesium-Rich Foods to Prevent Sudden Death

Most men and women who succumb to heart disease die suddenly without any known history of heart problems. As I note in my 3-min. video How Do Nuts Prevent Sudden Cardiac Death?, up to 55% of men and 68% of women have no clinically recognized heart disease before sudden death. They obviously had rampant heart disease, it just wasn’t recognized until they were lying in the morgue. So if there was ever a case to be made for primary prevention—starting to eat healthier right now, tonight—before symptoms arise, sudden cardiac death is it. Especially since our first symptom is often our last. OK, so how do we do it?

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. Why the decades-long delay in testing a potentially cheap simple way to help prevent our number one killer? That’s exactly the problem: cheap. Where’s magnesium found? Whole grains, greens, beans, nuts, and seeds. Who’s going to fund the study? The pumpkin seed lobby? Big spinach? If magnesium was found to be protective, who’s going to profit? Who’s going to benefit? Other than, of course, the hundreds of thousands of Americans that keel over dead every year without even being able to say goodbye to their families.

Watch my video Mineral of the Year–Magnesium to see what the new studies discovered.
