The effects of potassium, magnesium, calcium, and fiber on risk of stroke

Stroke mortality represents the third leading cause of death worldwide, aft er coronary artery disease and cancer. High blood pressure is a major risk factor for stroke. A recent study has identified potassium, magnesium, and fiber as significant modulators of stroke risk in men. The protective effec ts were particularly pronounced in hypertensive subjects. The observed prot ection may be due to direct and indirect effects of these nutrients on bloo d pressure and regulatory functions, such as endothelial function. A high i ntake of these nutrients, singularly or in combination, is associated with a more healthful overall lifestyle. The best strategy to achieve a high int ake of these nutrients is a diet rich in fruits and vegetables.
