kamama94, I want to say Welcome to Connect. I am happy that you have joined in this discussion, and I am pleased to see that your dietary changes are having positive effects. I am a liver/kidney recipient, and I feel it is necessary to tell you that i do not have any kidney experience, because my kidney failure was acute and related to my liver condition. It was just never on my health radar.
I have located some discussions where other members have shared some dietary suggestions and changes that they have made. I invite you to have a look, and to join in anywhere.
