Proteinuria (excess protein in the urine) is an important medical sign—not a disease itself, but often a signal that the kidneys need extra care. It may be linked to conditions such as high blood pressure, diabetes, or inflammation.
While no food can “stop proteinuria overnight,” a balanced, kidney-friendly diet may support overall kidney function, reduce inflammation, and help protect blood vessels over time.
Below are 10 gentle, nutrient-rich foods often included in supportive eating patterns for kidney health.
