Discharge Instructions: Eating a High-Potassium Diet

Your healthcare provider has told you to eat a high-potassium diet. This may be because you have low levels of potassium in your blood. Or it may be because you have high blood pressure. Potassium is found in many foods. These include dairy products, nuts, seeds, and beans. It’s also found in many fruits and vegetables in high amounts.

Guidelines for a high-potassium diet

  • Eat fruits and vegetables in their fresh or raw form most often.

  • Check labels for ingredients that have potassium. This includes potassium chloride. Add these items to your diet.

  • Try salt substitutes. Many of these have potassium.

  • Avoid licorice. This includes licorice root and teas that have licorice. These can rob your body of potassium.

Eat plenty of the following high-potassium foods:

  • Fruits. Good choices are apricots (canned and fresh), bananas, cantaloupe, honeydew melon, kiwi, nectarines, oranges, orange juice, and pears. Dried fruits include apricots, dates, figs, and prunes. Prune juice also has potassium.

  • Vegetables. Good choices are asparagus, avocado, artichoke, broccoli, bamboo shoots, beets, brussels sprouts, cabbage, celery, chard, okra, potatoes (white and sweet), pumpkin, rutabaga, spinach (cooked), squash, tomatoes. Also good are tomato sauce, tomato juice, and vegetable juice cocktail.

  • Chicken, fish, clams, and crab

  • Milk, chocolate milk, buttermilk, and soy milk

  • Legumes. These include black-eyed peas, chickpeas, lentils, lima beans, navy beans, red kidney beans, soybeans, and split peas.

  • Nuts and seeds. Try almonds, Brazil nuts, cashews, peanuts, peanut butter, pecans, pumpkin seeds, sunflower seeds, and walnuts.

  • Breads and cereals. These include bran and whole-grain products.

  • Others foods include chocolate, cocoa, coconut milk, and molasses
