I've gleaned that eating a lot of protein puts extra stress on your kidneys, but it was not my neph who told me that. The only doctor who has ever said anything to me about the protein issue was the transplant surgeon I met at my first eval back in 2004. It was the day before T-giving, and he flippantly told me not to eat too much turkey.
I restrict myself on the Pre-D diet because it makes me feel like I have some sort of control over my situation. It's psychologically comforting to me to be able to skip the bananas and eat berries instead. It's something I can do to keep myself healthy because Lord knows there's not much else I can do. FSGS has control over my life.
