10 Foods That Heal Kidney Disease: A Nutritional Guide
Kidneys play a pivotal role in maintaining overall health by filtering waste products and excess fluids from the blood, regulating blood pressure, and balancing electrolytes. When kidney function is compromised, it can lead to serious health complications. While medical intervention is often necessary, dietary choices can significantly impact kidney health. Certain foods are known to support kidney function and may even contribute to the healing process. These foods are rich in nutrients that help reduce inflammation, lower blood pressure, and prevent the buildup of harmful substances in the body.
