30+ Healthy Low Potassium Farmer’s Market Food Finds for Kidney Diets

Whether you’re avoiding high-potassium foods or adding potassium-rich foods, the farmer’s market offers some good foods to eat for kidney health. Farmer’s market foods are also eco-friendly and typically less expensive.

While you’re at the farmer’s market (search Local Harvest to find one near you), remember the following information about potassium so you can make the best choices for your diet.

Low potassium selections

The low potassium fruits and vegetables in this list (below 200 mg/serving) are healthy choices, especially for people on hemodialysis who need to avoid high potassium levels. Patients with chronic kidney disease (CKD) but not on dialysis may have normal or low potassium levels and don’t require potassium restriction if their lab values are normal on an unrestricted potassium diet.

High-potassium fruits and vegetables

The high potassium fruits and vegetables (over 200 mg/serving) in the list below may need to be limited if you are on a low-potassium diet. However, it’s possible to plan small amounts of some of these foods and still stay within your daily target for potassium. Portion size and frequency are important considerations.

 If you’re on peritoneal dialysis (PD you may need to add high potassium foods to avoid potassium depletion. If you’re on home hemodialysis (HHD) or nocturnal dialysis you may find your kidney diet is more liberal in potassium since the treatment provides more dialysis than traditional in-center hemodialysis. People in early stages of CKD usually don’t require a potassium restriction unless blood levels are above normal.

Some vegetables, like potatoes, can be double-boiled or soaked to reduce potassium. The above food lists don’t include high-potassium fruits like banana, kiwi or mango or high-potassium vegetables like bitter melon, bamboo shoots or taro, as these are  imported from other countries. Ask your renal dietitian for additional information on potassium sources in the kidney diet.
