Potassium-rich diet could lessen stroke risk

A review of 11 studies in the Journal of the American College of Cardiology found that as potassium intake went up the patient's risk of suffering stroke went down.

Scientists say this doesn't prove that potassium itself deserves the credit, but the foods highest in the mineral, including many fruits and vegetables, are considered generally healthy choices.

In theory, a diet with enough potassium could trim a person's risk of heart disease and stroke because the mineral helps lower blood pressure.

Other potassium rich foods include tomatoes, bananas, plums and raisins among the richest sources.
