Are low level kidney diseases and high protein diets connected?

See below. I am unclear about your question, but if you mean does high protein diet cause quicker deterioration of kidney function, then the answer is potentially yes.
Protein. Dietary protein can stress kidneys. Animal research shows that high protein intake accelerates progressive kidney disease. Limiting protein intake can slow the progress of kidney disease. This is difficult to demonstrate in humans, but human studies have shown renal stress from high protein intake. I share the concern that high protein diets strain human kidneys and can harm chronic kid dz.
