According to a new review, approximately 30 million Americans—about 15% of adults—have chronic kidney disease (CKD), a number that is expected to increase in the next 20 years due to rising obesity rates and longer life spans, but the majority of CKD patients aren’t receiving potentially lifesaving treatment.

“Medical Nutrition Therapy for Patients with Non-Dialysis-Dependent Chronic Kidney Disease: Barriers and Solutions” was compiled by a multidisciplinary team that included registered dietitian nutritionists, patient advocates, and physicians from the Academy of Nutrition and Dietetics, the National Kidney Foundation, Loyola University Chicago, and the University of New Mexico. It will be published in the October issue of the Journal of the Academy of Nutrition and Dietetics and is available online.

Nearly 90% of patients with CKD never meet with a registered dietitian nutritionist, according to the review. Some physicians may lack confidence in MNT’s effectiveness; others may be unaware that MNT is covered by Medicare Part B for patients who are not on dialysis. Patients may be reluctant to invest the time and money in the therapy if it is not covered by their insurance.

“Most patients don’t understand how big a role their diet plays in the management of their kidney disease,” said coauthor Marsha Schofield, a registered dietitian and the Academy’s senior director of governance. “Medical nutrition therapy helps patients with chronic kidney disease improve their blood sugar and blood pressure, which will slow the progression of the disease and even delay or prevent them from needing to have dialysis or a transplant.”

“The Academy and the National Kidney Foundation have a long history of collaborating to advance the science and clinical practice around kidney disease,” Schofield said. “Both of our organizations recommend MNT for all people with CKD.”
