Top 10 Foods Lowest in Potassium For People with Kidney Disease

Essential electrolytes like potassium are typically regulated in your body by your kidneys. For those diagnosed with chronic kidney disease (CKD) you may have to limit consumption of potassium and other electrolytes. The list below serves as a suggestion of low potassium foods for your diet. Since other electrolytes should also be watched, the amounts of sodium, phosphorus, magnesium, and calcium are also listed.

Foods low in potassium include most refined fats and oils, grains like cornmeal, white rice, and white pasta, cheeses like soft goat cheese, and blueberries, leeks, and napa cabbage. Boiling vegetables in water and discarding the water they are cooked in can help reduce their potassium and electrolyte content. Further, you can also leech more minerals out by soaking vegetables in water prior to consumption. Below are the top 10 foods lowest in potassium.
