Salt, Potassium and BP Control

Potassium helps the kidneys remove excess sodium and relaxes blood vessels, while limiting salt reduces fluid retention and high blood pressure. The World Health Organization recommends that adults consume no more than 5 grams of salt a day. A scientific review suggests that reducing sodium while increasing potassium may support heart health: a study of more than 10,000 people found that higher urinary sodium was associated with an increased risk of heart disease, while higher potassium was associated with a lower risk. Sources of potassium include bananas, oranges, potatoes, sweet potatoes, spinach, broccoli, beans, lentils, milk, yogurt, nuts, and seeds. However, people with kidney disease and those taking medications that affect potassium levels should consult a doctor before using potassium supplements or potassium-containing salt substitutes.
