Dietary fiber and protein: nutritional therapy in chronic kidney disease and beyond.

Summary: Your kidneys do more than just filter waste; they are closely connected to your gut health. In people with Chronic Kidney Disease (CKD), eating protein—while necessary—can have a downside: it feeds harmful bacteria in the gut, leading to inflammation and a buildup of toxins. However, new research highlights a powerful solution: dietary fiber. Fiber acts as a buffer, reversing these harmful effects and improving gut health. Experts now suggest that CKD patients should increase fiber intake, or use potassium-free prebiotics, to protect their kidneys and reduce inflammation.
