Fruits and Vegetables High in Potassium

Potassium puts stress on your kidneys, so it must be limited in a kidney disease diet. Many fruits are high in potassium, such as melons, bananas, oranges, prunes and tomatoes, both eaten and in juices. The mineral is also higher in dairy products, avocados, bran, beans, lentils and nuts. You may be surprised to learn that dark-colored sodas are higher in potassium, as are fruit punches and prepared (canned and bottled) iced tea. Lower-potassium foods include apples, grapes, strawberries, cauliflower, white breads, pita, chicken and white rice.
