Your body's 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. (1) 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.
