Here's what researchers found after analyzing 10 international studies involving more than 200,000 people:
Across the board, stroke risk dipped as potassium intake went up.
For each 1,000 milligram increase in daily potassium the odds of suffering a stroke declined by 11 percent.
The findings do not prove potassium itself produces the positive effect. But this study in the journal Stroke strengthens existing evidence that it might.
Potassium-rich foods include beans, and a variety of fruits and vegetables, and low-fat dairy.
