Patients with high blood pressure have always been told to decrease their salt intake, but according to a new study at Loyola University Health System, Chicago, adding potassium to your diet is a good choice as well. The study, which included 2,974 participants, found that the ratio of sodium-to-potassium in a subject's urine was a much stronger predictor of cardiovascular disease than sodium or potassium alone. "There isn't as much focus on potassium, but potassium seems to be effective in lowering blood pressure and the combination of a higher intake of potassium and lower consumption of sodium seems to be more effective than either on its own in reducing the risk of cardiovascular disease," says Dr. Paul Whelton, senior author of the study. Foods especially high in potassium include fat-free milk and yogurt, orange juice, bananas and tuna.
