Understanding the heart-healthy
benefits of potassium
Foods that are rich in potassium are important in managing high blood pressure (HBP or hypertension) because potassium lessens the effects of sodium. The more potassium you eat, the more sodium you lose through urine. Potassium also helps to ease tension in your blood vessel walls, which helps further lower blood pressure.
Increasing potassium through diet is recommended in adults with blood pressure above 120/80 who are otherwise healthy. Potassium can be harmful in patients with kidney disease, any condition that affects how the body handles potassium, or those who take certain medications. The decision of whether to take excess potassium should be discussed with your doctor.
Potassium and your diet
The recommended potassium intake for an average adult is 4,700 milligrams (mg) per day.
