Potassium-rich foods may reduce the risk of stroke
Plant foods are rich in the mineral potassium, which has a number of important functions in the body, including keeping blood pressure down. The Standard American Diet is low in potassium; less than 3 percent of the women in this study were meeting recommendations for adequate potassium intake. The study found that older women who consumed the most potassium had a 16 percent lower risk of ischemic stroke (the most common type of stroke) than those who consumed the least.
