How to Make the BEST Low Potassium Potatoes

This garlicky mashed potato recipe is kidney-friendly and perfect for those looking to lower their potassium intake! Kidney or renal nutrition recommendations can differ depending on your Chronic Kidney Disease (CKD) stage and can make planning a kidney-friendly diet feel baffling. Since potassium is so widespread in food, it is important to be extra careful with foods that are traditionally high in potassium. We want to ensure that you have a kidney-friendly recipe that will work for you at mealtimes and holidays in the future. Keep on reading to learn more about a kidney-friendly diet and our low potassium potatoes.

There are four vital components to consider when following a kidney-friendly diet:

  1. Potassium
  2. Phosphorus
  3. Sodium
  4. Protein

With CKD, your kidneys have a hard time filtering waste and minerals from your blood. That is why the above minerals (and protein) are of concern. When we eat food, our body breaks it down and some of the broken down particles enter our blood. Eventually, the blood will go to our kidneys to be filtered. We want to limit how much potassium, phosphorus, sodium, and protein we are eating to prevent overloading and overworking our kidneys.

So, why are low potassium potatoes important for kidney disease? Potatoes are high in potassium (also know as “K”) which is a nutrient that must be limited when following a diet to manage kidney disease. People following a kidney-friendly diet can cut up and soak their potatoes in water to reduce their potassium content. In fact, an average medium-sized potato with the skin contains 926 milligrams of potassium. Cutting, soaking, and boiling your potatoes can reduce the potassium content by at least half of the original amount! Keep in mind, it is still important to watch your portion sizes as many others foods on your plate may be high in potassium such as avocados, bananas, and Brussel sprouts.

While boiling can be great for potatoes, we do not recommend soaking and boiling all foods. Vegetables, which can be high in potassium, also have important water-soluble vitamins, like vitamin C, which can be lost in the process of soaking or boiling.
