Is Egg Good for Proteinuria?
Egg consumption's effect on proteinuria is complex and depends on several factors, including the type of egg (whole egg vs. egg white), the underlying cause of proteinuria, and the overall dietary intake.
Studies have shown that whole egg consumption may have a nephroprotective effect, meaning it might help protect the kidneys. One study found that whole egg consumption attenuated (reduced) polyuria (excess urination), proteinuria, and renal hypertrophy (enlarged kidneys) in rats with type 1 diabetes. Whole egg consumption attenuated polyuria, proteinuria, and renal hypertrophy in T1D rats. 18-Jan-2018 This suggests a potential benefit in specific contexts.
Egg Whites and Proteinuria: A Different Perspective
While whole eggs show promise in some studies, the impact of egg whites on proteinuria is less clear. Egg whites are a good source of protein, but their effect on proteinuria in individuals with kidney disease needs further research.

Considerations for Kidney Disease and Proteinuria
For individuals with chronic kidney disease (CKD), dietary protein intake, including from eggs, needs careful management. Eggs contain phosphorus, a mineral that can accumulate in the body when kidney function is impaired. Therefore, egg consumption should be moderated and ideally discussed with a healthcare professional.

Egg whites have less phosphorus than whole eggs 10 Foods to Eat or Avoid If You Have Kidney Disease - Durham Nephrology and can be a better choice in some cases.
Conclusion
The relationship between egg consumption and proteinuria is nuanced. While whole eggs might offer some renal protection in certain situations, like type 1 diabetes, the impact of eggs on proteinuria in individuals with kidney disease requires careful consideration and personalized management by a healthcare professional. Egg white's impact needs more study.
