A recent Spanish study has purportedly revealed that increased intakes of magnesium may decrease mortality rates as much as 34 percent in adults with high cardiovascular risk. Marta Guasch-Ferré, et al., “Dietary Magnesium Intake Is Inversely Associated with Mortality in Adults at High Cardiovascular Risk,” The Journal of Nutrition, November 20, 2013. Using a database of 7,216 men and women ages 55 to 80 from the Prevención con Dieta Mediterránea study, participants at a high risk of cardiovascular disease were randomly assigned to Mediterranean diets supplemented with nuts or olive oil—high in magnesium—or a low-fat control diet. According to data collected during a five-year period, 323 total deaths, 81 cardiovascular deaths and 277 cardio- vascular events such as stroke, heart attack and heart disease, occurred. The data also revealed that the highest average intakes of magnesium (442 mg/ day) were associated with a 59-percent reduction in cardiovascular mortality, a 37-percent reduction in cancer mortality and a 34-percent reduction in all-cause mortality, compared to the lowest average intakes of approximately 312 mg/day.
