I hear a lot about the importance of a kidney-friendly diet for kidney patients.
But what I don't quite understand is if this diet actually helps the kidneys function better.
Ok, so we have less protein and potassium and other substances (depending on our body needs), we stay hydrated, and so on.
The eGFR (Glomerular "filtration" rate) raises and it makes us feel happy! But isn't it just because we are having less of those things? We have less protein, we'll have less creatinine in our blood.
The increase in "filtration" rate as a result of having less protein doesn't really sound like the filtration rate is increasing. It seems more like deceiving ourselves because there's less to get filtered anyway!
Or maybe I don't really understand the way it works. I don't know. Maybe, it is because the kidneys don't have to work as hard to remove waste products and excess fluid from the body, and the less hard they work the longer they can stay in shape! and as a result, the progression slows down?
But still, to me it doesn't sound like the filtration rate is improving!
Does anyone know anything about this?
