Dietitians who specialize in kidney diseases are called renal dietitians.  Renal dietitians are the specialist on the impact of food on chronic kidney disease (CKD).  Renal dietitians typically have clinical experience working in hospitals, dialysis centers, or clinics that treat patients with kidney disease.  These RDs will also partake in continuing education to stay current with the latest research, treatment guidelines, and best practices in renal nutrition.
