Increasing potassium intake to reduce blood pressure and risk of cardiovascular diseases in adults

An estimated 17.3 million people died from cardiovascular disease in 2008, representing 30% of all deaths worldwide. High blood pressure (hypertension) is a major risk for cardiovascular disease, especially heart attack and stroke.

Evidence shows that increasing potassium intake significantly reduces blood pressure in adults. Potassium is found in a variety of unrefined foods, including beans and peas, nuts, vegetables such as spinach, cabbage and parsley and fruits such as bananas, papayas and dates. Food processing reduces the amount of potassium in many food products, and a diet high in processed foods and low in fresh fruits and vegetables is often lacking in potassium.

WHO recommends an increase in potassium intake from food to reduce blood pressure and risk of cardiovascular disease, stroke and coronary heart disease in adults. WHO suggests a potassium intake of at least 90 mmol/day (3510 mg/day) for adults.

These recommendations complement the WHO guideline on sodium consumption and should not be interpreted to replace or supersede that guideline. Public health interventions should aim to reduce sodium intake and simultaneously increase potassium intake through foods.
