Too much salt in your diet can cause your body to retain fluid and raise your blood pressure. Limit your total salt intake in your food to no more than 1500 mg per day. Your health care provider may recommend the D.A.S.H. (Dietary Approaches to Stop Hypertension) eating plan if you have high blood pressure. The DASH eating plan includes fruits, vegetables, whole grains, and other foods that are heart healthy and low in fat, cholesterol, and salt (sodium).
