Kidney Disease: Eating a Safe Amount of Potassium
Potassium is a mineral found in many foods. The body needs some potassium to keep the heart, muscles, and nerves working normally. But if your kidneys don’t work well, potassium can build up in your blood. It can be serious and even deadly if the levels go up too high. By controlling the amount of potassium you eat, you can keep a safe level in your blood.
Using this guide
Use this serving guide along with the food list below. Always follow your dietitian’s instructions on the number and size of servings to eat. You can leach some of the potassium out of some high potassium foods by soaking and cooking them in large amounts of water. Ask your dietitian about how to do this. Also talk with your dietitian before eating foods that aren’t on this list. Consider bringing your spouse or partner to your meetings with the dietitian. That way you'll additional support managing your diet.
