MooseMom, my renal dietician doesn't know much about the vegetarian diet at all. She hasn't been of much help.
Sam, I've been a vegetarian most of my life as well. I never had to alter my diet for ESRD because no matter what, my labs stayed in range. Then again, I did not really eat, so if you have a small enough portion of anything, it will not really affect your labs. They say that phosphorous from vegetarian sources is not absorbed as fully as from meat sources, perhaps that contributed as well? I think my potassium was once at the border of high, but that was the worst it ever got. Eggs are of course a good source of protein if you eat those. How about tempeh, tofu, seitan? Do you like those? Quorn if you are not vegan and don't mind the meat imitators? There are carbs that are also decent sources of protein - quinoa, spelt, etc. I loathe milk, so I could not drink those protein drinks myself. I have discovered Oat Milk and I love it for cereals, but I think that is actually high in potassium and phos.There should be no need to eat meat, and I strongly believe you would get very sick if you tried. You lose the ability to digest it, and I have been quite ill from this. I was once trapped at my job, absolutely starving (and was expecting, so more pressure to eat). I knew I could not get out of there for another 8 hours or so, and all I had was a frozen entree to chuck into the micro. It was a Wolfgang Puck pasta or something, I heated it and could immediately taste chicken. I had not read the ingredients because it sounded vegetarian, but they had used chicken broth. I choked it down out of desperation and upchucked violently once I got home. Do not do this to yourself.Just as an aside, I am a vegetarian because the thought of eating meat grosses me out. My family eats meat while I'm at the table with them almost every day - I have no desire to influence others to join me in vegetarianism. So, I am not trying to convince you to fulfill my political agenda. Aren't most meats reasonably high in potassium as well? The nutritionists with whom I spoke were all quite excited when I kept going on about my longstanding love of tofu. That has also been shown to improve kidney function. I think you'll be ok with that sort of protein source.
Oh, there's a surprise...
