Dietary fiber and protein: nutritional therapy in chronic kidney disease and beyond.Kidney Int. 2012 Feb; 81(3):227-9.KI
The health benefits of dietary fiber in the general population are increasingly recognized. Krishnamurthy et al. provide compelling evidence that chronic kidney disease (CKD) further augments these benefits. CKD, besides a microinflammatory state, is a state of increased proteolytic fermentation. Both these harmful conditions are exacerbated by dietary protein and reversed by dietary fiber. Future nutrition guidelines should consider recommending a higher consumption of dietary fiber or potassium-free alternatives such as prebiotics in CKD patients.
