@bdade59, yes, fish is included on many renal diets. But I am a vegan so consume no animal products at all, meaning no dairy, no eggs, no meat of any kind, not even jello made with gelatin since that's an animal product. Doing better this spring than past winter although foot swelling increased and when neph put me on metolazone and I had a very bad tummy reaction to it and stopped it. You've had quite a time if you've had cancer and have only one kidney now.. Sounds like you're battling several issues. I send you positive vibes and healing thoughts!
