It shouldn’t tax a working kidney so much that you can’t practically have it. Even the breakdown of existing protein needs to go out your kidneys, regardless of ever bringing in more, for what is not redistributed elsewhere in the body (and I think even redistributed protein/amino acids still flow into, and are routed out of, the kidneys, if deemed needed).
For me, it was an easy transition to plant and fish proteins. The trick is to not rely on carbs as a replacement. Lost 20 pounds since my CKD diagnosis but the payoff is feeling much younger.
If I can stay healthy at age 82, with no diabetes, no heart issues, no prostate issues, no kidney issues, no signs of dementia, and enough stamina to mow my lawn with push mower during Florida summers, I think I must be doing something right.
Very briefly, lots of fruits & vegetables, less refined grains, less red meat, more fish & chicken, 1 multi-vit pill daily, and moderate aerobic exercise 5 days every week.
Should all kidney patients limit all types of protein ?
