How can I prevent hyperkalemia (high potassium)?

If you’ve had hyperkalemia or are at risk for it, a low-potassium diet is the best way to protect your health. You may need to cut back on, or completely cut out, certain high-potassium foods, such as:

  • Asparagus.
  • Avocados.
  • Bananas.
  • Citrus fruits and juices, such as oranges and grapefruit.
  • Cooked spinach.
  • Melons like honeydew and cantaloupe.
  • Nectarines.
  • Potatoes.
  • Prunes, raisins and other dried fruits.
  • Pumpkin and winter squash.
  • Salt substitutes that contain potassium.
  • Tomatoes and tomato-based products like sauces and ketchup.
