Recent research revealed the importance of potassium intake in reducing blood pressure and risk of heart disease. Study also revealed that sodium-to-potassium in subjects' urine is a better indictor of cardiovascular disease than sodium or potassium alone.

Lead researcher, Dr. Paul Whelton, president and CEO of Loyola University Health System, said: "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."
