A recent analysis of scientific research suggests that a diet rich in potassium may be linked to a lower risk of stroke. Potassium is found in various foods, including bananas, potatoes, tomatoes, plums and beans.
The researchers analyzed 11 studies that followed more than 247,000 adults for up to 19 years. In most of the studies, the participants completed food questionnaires. Other trials took urine samples to determine potassium intake.
The researchers found that for every 1,640-milligram increase in potassium consumption, stroke risk reduced by 21 percent. No such link was found between potassium and heart disease risk.
However, the study does not prove a cause-and-effect relationship. More research is needed to confirm these findings.
