A low-sodium diet may work as well as medicine to lower blood pressure and improve heart function in people with heart failure. People with high blood pressure and heart failure who went on a 21-day diet containing no more than 1,150 milligrams of sodium per day saw the same level of improvements that medication provides. Participants followed the DASH (Dietary Approaches to Stop Hypertension) diet, which is high in potassium, magnesium, calcium and antioxidants. Americans typically take in 3,000 to 4,000 milligrams of sodium each day.
