Effect of High Protein Diet on Kidney Function

High protein intake does not have a significant impact on kidney function in individuals with normal kidney function. Hyperfiltration, the increased filtration rate in response to higher protein intake, is an adaptive response and does not pose a risk for kidney disease. For individuals with chronic kidney disease, current recommendations suggest low protein or very low protein diets to slow disease progression and reduce the risk of end-stage kidney disease. However, the evidence supporting these recommendations is not very strong, and the potential benefits of protein restriction need to be weighed against the challenges of adhering to such diets. Overall, there is no strong connection between high protein intake and kidney damage, and other factors such as underlying health conditions and medication usage may have a more significant impact on kidney health.
