Your body needs a little bit of salt every day for the sodium it contains. But too much sodium can boost blood pressure and stress the heart and blood vessels. The low-sodium Dietary Approaches to Stop Hypertension (DASH) diet is high in fruits, vegetables, and whole grains; moderately high in nuts and low-fat dairy products; and low in red and processed meats. Following it can lower blood pressure and reduce the risk of heart disease and stroke.
