Honestly I can't find any fault here. Giving up the drinking and smoking has probably been monumentally difficult, and it's amazing that he's been able to do that. That alone tells me he is committed to getting healthier.

The diet stuff... honestly, nutrition "science" is full of contradictions. Sure, too much of anything is probably bad for you, but I don't think diet concerns should be a blocker for receiving a transplant.

At any rate, sorry you and your family has to go through this, and best wishes for your uncle's recovery.
