You may have heard that you need to cut back on potassium because you have kidney disease. That’s probably why you are looking for a high potassium food list.

The truth is that not everybody needs to cut back on potassium just because they have kidney disease. In fact, it is one of the biggest perpetuated myths in the kidney world.  However, maybe your potassium was recently high on your blood work and you’re needing to figure out how to bring it down. If so, then let’s dig into the basics of potassium.

Potassium Element Sign on a Periodic Table

What is potassium?

Potassium is an essential mineral and electrolyte involved in many bodily functions, including:

  • Muscle contractions
  • Nerve transmissions
  • Blood pressure control

Potassium and kidney disease

Kidneys play a crucial role in regulating potassium levels in the body. When kidney function is compromised, the kidneys may struggle to remove excess potassium from the blood. As a result, there may be a buildup of potassium in the blood.

High potassium doesn’t actually hurt your kidneys, but for the individuals who have higher levels it can cause some problems. High levels of potassium may lead to complications such as irregular heartbeat, muscle weakness, and even emergency hospitalizations.

Good news!

You CAN manage high potassium through food. That is, by choosing mainly low potassium foods and reducing intake of high potassium foods.

Please note: potassium restriction is NOT for everybody. Many people with kidney disease may actually benefit from more potassium intake. Unsure if you should limit your potassium? Book a call with your KNI dietitian and clarify your nutrition strategies today!

Non-dietary causes of high potassium

Contrary to common beliefs, your dietary potassium intake is NOT the only cause of high potassium levels. Beyond food intake, there are many other causes of high potassium in the blood, including:

  • Some medications
  • Metabolic acidosis
  • High blood glucose
  • Hydration status
  • Gut problems including vomiting, diarrhea, or bleeding
  • Constipation

When addressing high potassium, it is crucial to consider all these potential causes in addition to restricting potassium from your food intake.

Please make sure to always work with your healthcare team to determine the best approach to address your potassium levels.
