Certain fresh fruits and vegetables that are common in ordinary diets are also very high in potassium. Spinach, tomatoes and tomato juices, bananas, fresh avocado, oranges and figs are all examples of high potassium fruits and vegetables. Better choices include apples, apricots, berries like strawberries and blueberries, green beans, cabbage and eggplant. Instead of removing certain dishes from the dinner table, use menu replacements. For example, potatoes are high potassium, so instead of serving mashed potatoes, try steaming and mashing cauliflower instead which is a vegetable lower in potassium.
