Low Potassium Vegetables

Low Potassium Vegetables

For those diagnosed with chronic kidney disease (CKD) the shock of being diagnosed is often accompanied by dietary guidelines restricting the intake of potassium and other electrolytes. The next realization is that almost all vegetables contain some amount of potassium.

While this is true, there are a few vegetables that are lower in potassium, and the amount of potassium in vegetables can be further reduced by soaking the vegetables in water before cooking, in a process called leaching. This works well for vegetables that will be eaten raw. Cooked vegetables should be boiled, and the water they are boiled in should be discarded.

While the daily value (DV) for potassium is 4700 milligrams (mg), a vegetable can be considered to be "low potassium" if it has less than 200mg of potassium per serving (please watch portion sizes). (2) The list of vegetables below serves as a suggestion of low potassium vegetables for your diet and is for informational purposes only. Please work with your primary care provider to establish a proper diet.

The amount of potassium in vegetables may vary based on the soil and conditions in which they are grown. The numbers below can be considered averages across the U.S. To be safe, incorporate new vegetables into your diet slowly and in small quantities.

Low potassium vegetables include cilantro, alfalfa sprouts, lettuce, arugula, kale, Napa cabbage, leeks, spaghetti squash, sweet onions, eggplant, and more. For more low potassium vegetable ideas, see the complete ranking of over 200 vegetables low in potassium.

Most vegetables are low in calories, and so should be eaten with other low potassium foods.

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.
