Top 10 Foods Lowest in Potassium For People with Kidney Disease

Top 10 Foods Lowest in Potassium For People with Kidney Disease

The kidneys regulate potassium (and all electrolyte) levels in your body. For those diagnosed with chronic kidney disease (CKD) you may have to limit consumption of potassium and other electrolytes. (2)

The list below serves as a suggestion of low potassium foods for your diet and is for informational purposes only. Please work with your primary care provider to establish a proper diet.

Generally people with CKD should watch their protein intake, as well as intake of other electrolytes. Since other electrolytes should also be watched, the amounts of sodium, phosphorus, magnesium, and calcium are also listed below each food in this list.

Foods low in potassium include most refined fats and oils, grains like cornmeal, white rice, and pasta, cheeses like soft goat cheese, and blueberries, eggs, leeks, Napa cabbage, and chia seeds. Boiling vegetables in water and discarding the water can help reduce their potassium and electrolyte content. Further, you can also leech more minerals out by soaking vegetables in water before consumption.

For more information on a CKD diet see the article from Medline Plus and Kidney.org. For more low potassium food ideas see the nutrient ranking tool, nutrient ratio tool, and the list of low potassium vegetables.

About Nutrient Targets

Setting targets can provide a guide to healthy eating.

Some of the most popular targets include:
  • Daily Value (%DV) - The %DV is a general guideline for everyone and accounts for absorption factors. It is the most common target in the U.S. and is the target on the nutrition labels of most products. It is set by the U.S. FDA.
  • Reference Dietary Intake (%RDI) - The Reference Dietary Intake (RDI) is a customized target accounting for age and gender. It is set by the U.S. Institute of Medicine. The RDI for amino acids is set by the U.N. World Health Organization. The daily value (%DV) builds on the reference dietary intake to create a number for everyone.
  • Adequate Intake (%AI) - Sets a target for Omega 3 and Omega 6 fats. The Adequate Intake is also set by the U.S. Institute of Medicine. It represents a number to ensure adequacy but lacks the same level of evidence as the Reference Dietary Intake. In short, the number is less accurate than the RDI.
  • See the Guide to Recommended Daily Intakes for more information.
