Our Editorial Process

We know there is so much information available online when it comes to a renal diet. We take the information we share on Plant-Powered Kidneys very seriously.

All blog articles are written and/or reviewed by registered dietitians, who have completed a minimum of 1,200 supervised hours through an accredited internship program, and passed a national registration exam.

Our board-certified renal dietitians (CSR) complete an additional 2,000 hours of nutrition counseling and teaching with kidney patients, as well as pass an additional national certification exam.

As dietitians, we are required to complete 75 hours of continuing education units every 5 years to keep abreast of current nutrition topics and to maintain our credentials. CSR dietitians must re-take their exam and provide evidence of 2,000 hours of nutrition counseling and patient teaching every 5 years to maintain their specialist certification.

Articles on our blog include references from sources such as the National Kidney Foundation, the National Institute for Diabetes and Digestive and Kidney Diseases (NIDDK), as well as peer-reviewed articles and research on The National Institute of Health PubMed.

Additionally, articles are reviewed and updated annually to reflect any new research or information pertinent to the information we provide.
