What is a good diet to keep potassium low.

@lizzy4 Welcome to Mayo Clinic Connect! You have had some great responses already here!

I am a dialysis patient, doing peritoneal dialysis everyday. For many years before dialysis, my renal diet included watching my potassium level. That to me meant no potatoes, no oranges [except Mandarin], no tomatoes, no bananas. Following a printed list of high and low potassium foods, my diet was modified. Fast forward to now, and I take furosemide which helps my system expell excess fluids. It also can play havoc with healthy potassium levels, needed a for healthy heart. So, I take prescription potassium supplements, in addition to being free to eat all those foods I couldn't before. Can I tell you how good my first taste of hand squeezed orange juice was?!

Our diets can be a complicated thing, always a balancing act, given our individual health situation. I hope your husband can team up with his care team and include a renal nutritionist https://www.renalnutrition.org/home to get the best eating plan for him. Oftentimes we are dealing with multiple heath concerns and need to incorporate different eating plans together. It's not easy, is it?
