Kidney Patients With High Blood Potassium Can Still Eat Vegetables: Nutritionist Teaches 3 Methods to Remove Potassium

For individuals with chronic kidney disease or those on dialysis, managing high blood potassium levels often means restricting vegetable intake. However, a nutritionist from Daye Clinic suggests this is not the only solution. Chen Yi-ching emphasizes that severe hyperkalemia can lead to fatal heart arrhythmias, but complete avoidance of vegetables can cause insufficient dietary fiber and constipation.

Severe hyperkalemia can cause arrhythmias, even endangering life. Patients should adjust their diet based on blood potassium levels and kidney function.

Chen Yi-ching shared a "cut, boil, drain" method to significantly lower the potassium content in vegetables. First, cut vegetables into small pieces or thin shreds to increase surface area for potassium release. Second, boil the vegetables in plenty of water for three to five minutes, avoiding methods that use minimal water, which are less effective. Finally, drain the water thoroughly before seasoning.

Cutting vegetables into small pieces, boiling them in ample water for 3-5 minutes, and draining the water are the three steps to reduce potassium.

She stressed that the boiling water, which contains the leached potassium, should not be consumed or used for soups or thickening agents. Seasoning with moderate oil, garlic, or spices can make the kidney-friendly diet palatable. Chen Yi-ching advises that the degree of potassium restriction varies among patients, and those with normal potassium levels may not need to limit fruits and vegetables excessively. Adjustments should be based on blood test results and individual recommendations from doctors and nutritionists.

The boiled water should not be drunk or used for soups or thickening agents, as the leached potassium is in the water.
