About Potassium

Nearly all foods contain some potassium, including healthy ones like fruits, vegetables, and dairy. If you have kidney disease, you need to control your intake of these foods. That could mean avoiding some fruits and vegetables altogether, or it may just mean reducing the amount of high potassium foods you eat. If your blood test showed that the potassium level in your blood was too high, this could be dangerous to your heart. Choosing foods low in potassium will help reduce the potassium in your blood. Foods that are high in potassium should not be eaten when your blood level is high.
