A Doctor of Clinical Nutrition (DCN) is someone who is great at clinical nutrition practice and research, and who likes grad school!

To become a DCN, you have to complete a lot of graduate course work (50-credits past an MS degree), a residency, and publish outcomes research.

Because it takes foreverrrr to complete, only a couple percent of all registered dietitians (RDs) finish. When you are finished, yes, you get to call yourself a Doctor!

Our nutritionist extraordinaire here at Dietitian Doc is a DCN, and yes, we do call her Doctor!

A Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN) is a credentialed  nutrition expert. You can choose to call yourself an RD or an RDN.  

To become an RD you need a graduate degree in dietetics, sail through a 900-1200-hour internship, and pass a board exam.

As of 2021, there are 108K RDs in the US!

Some places where RDs work are hospitals and universities, and some are lucky enough to have their own practice. 

Our nutritionist extraordinaire here at Dietitian Doc is an RD! Her RD badge is proudly displayed in the footer! 

A cancer nutritionist is credentialed via something called Board-Certified Specialist in Oncology Nutrition (CSO).

To become a CSO, you must have been an RD for two years, have a lot of field experience (2K hours), and pass a board exam.

As of 2021, just over 800 RDs in the US have a CSO credential, which allows them to call themselves cancer nutritionists or cancer dietitians!

CSOs mainly work in cancer centers and private practice. They manage nutrition care, reduce malnutrition, and treat side effects of cancer treatment.

Our nutritionist extraordinaire here at Dietitian Doc is a CSO! Check out the footer to see her CSO-credential badge. 

Nutrition support is giving food and water via a tube to people that can’t eat normally because of a disease, recent operation, or trauma.

It’s managed by Board-Certified Nutrition Support Clinicians (CNSCs), and as of 2021, there are 5K in the US.

CNSCs mainly work in hospital intensive care units (ICUs) and nursing homes.

To be awarded a CNSC you need to have worked in the field for two years and, of course, pass a board exam.

Our nutritionist extraordinaire here at Dietitian Doc held a CNSC for 10 years while working in different trauma center ICUs.

She also wrote a chapter in the American Society for Parenteral and Enteral Nutrition (ASPEN) Core Curriculum that clinicians use to pass the board exam. 

Licensure was created to help the general public find qualified nutrition practitioners.

It’s governed at the state level, and it’s up to every state to decide whether or not to license practitioners in their state.

Most states require a license, while others license nutritionists without any credentials.

At Dietitian Doc, we’re licensed in dietetics/nutrition in the state of Alabama.

This means that we can provide medical nutrition therapy to people living in Alabama. 

Evidence-Based Practice (EBP) is a systematic approach to solving a problem. It’s a process for evaluating research to arrive at the best possible solution to that problem.

Evidence ranks from a type of research called systematic reviews and meta-analyses at the top, to educated opinions at the bottom. The goal is to present the highest evidence available.   

Evidence-based practice is considered the GOLD-STANDARD in nutrition practice and assures that practitioners’ advice is based on research and not taken out of thin air.

Evidence-based practitioners must understand research and remain unbiased by weak facts, popular beliefs, and personal opinions.

Our nutritionist extraordinaire here at Dietitian Doc is an expert in evidence-based practice.

She has doctorate-level expertise, has been the principal investigator of multiple large research studies, and is published in multiple peer-reviewed journals.

At Dietitian Doc, we review each piece of content through an evidence-based lens. To be up-to-date, we also review our content on an annual basis. 

Please note that any content on this site is for general information only and not a meal plan or medical advice.

We suggest you work with your healthcare provider to come up with a plan that best promotes your health.
