More Potassium Reduces Risk of Stroke

Diet may play a role in stroke prevention. A new analysis of 11 studies found that the more potassium people get from their diet, the lower their risk of suffering a stroke. There were nearly 250,000 participants in the various trials, which followed some people for up to 19 years. Potassium is important for heart rhythm regulation. It also helps keep blood pressure under control and is essential for normal muscle and nerve function. Foods high in potassium include dark green leafy vegetables, broccoli, cauliflower, Brussels sprouts, potatoes, beets and tomatoes. Beans and nuts are also high in potassium along with many types of fish and low-fat dairy products. The scientists found that for each increase of 1,640 mg of potassium, the risk of stroke dropped by roughly one fifth.
