New research examined the association between magnesium, which has antiarrhythmic properties, and your risk of sudden cardiac death (SCD). The study looked at more than 88,000 women, who were followed for 26 years.
The results showed that the relative risk of sudden cardiac death was significantly lower in women in the highest quartile of dietary magnesium consumption. In fact, women with the highest blood levels of magnesium had a 41 percent lower risk of sudden cardiac death.
According to the study, in the American Journal of Clinical Nutrition:
"In this prospective cohort of women, higher plasma concentrations and dietary magnesium intakes were associated with lower risks of SCD. If the observed association is causal, interventions directed at increasing dietary or plasma magnesium might lower the risk of SCD."
