High intakes of magnesium and potassium are linked to a lower risk for stroke in women, according to a study from Brigham and Women’s Hospital in Boston. Dietary intakes of magnesium, potassium, and calcium were compared to subsequent stroke risk in 86,149 women in the Nurses’ Health Study. At the 30-year follow-up, a total of 3,780 strokes were documented. Women with the highest intakes of magnesium had a reduced risk for stroke of 13%, and an 11% reduced risk with high potassium intakes compared to women who consumed the least amount of these minerals. Calcium intakes did not show any benefit.
