Dietitians vs Nutritionists: The New RDN Credential

The line between “Dietitian” and “Nutritionist” often becomes blurred. Many people use these terms interchangeably, unaware that they represent different qualifications, scopes of practice, and standards. Just when you thought you had it all figured out, the Academy of Nutrition and Dietetics introduced a new term—Registered Dietitian Nutritionist (RDN).

What does this mean for the profession? Does it make things clearer or more confusing? Let’s make sense of it all.

What’s the Difference Between the Two?

To understand where the new RDN credential fits in, we first need to clarify the difference between a Dietitian and a Nutritionist. This distinction has been a topic of confusion for years. So, let’s break it down simply:

Criteria Dietitian (Registered Dietitian – RD) Nutritionist
Education Requirements Bachelor’s degree in nutrition, dietetics, or related field Varies widely; no formal requirements in many states
Supervised Practice Hours 1,200 hours through an accredited program Not required
Certification Exam Must pass a registration exam by the Commission on Dietetic Registration (CDR) Not required
Continuing Education Required to maintain credentials Not required
Regulation Regulated and credentialed by national and state bodies Often unregulated; anyone can use the title in many states
Scope of Practice Broad, including medical nutrition therapy (MNT) and clinical roles Varies, often limited by lack of formal credentials
Trustworthiness Generally high due to strict education and certification standards Hard to assess due to variability in qualifications

In short: All Dietitians are Nutritionists, but not all Nutritionists are Dietitians. One comes with strict qualifications, while the other can be much more variable.

The Introduction of the RDN Credential

As if things weren’t confusing enough, the Academy of Nutrition and Dietetics has thrown another term into the mix: Registered Dietitian Nutritionist (RDN). Effective immediately, RDs can now opt to identify themselves as RDNs.

The key word here is “optional”—there is no functional difference between an RD and an RDN. The Academy claims this new title is simply a way to reinforce that Dietitians are, indeed, also Nutritionists.

But why this change? The Academy of Nutrition and Dietetics felt the title of “Registered Dietitian” might be too limiting in the public’s understanding. They wanted to emphasize the broad range of nutritional knowledge and expertise that Dietitians have. Hence, the “Nutritionist” portion of the title was added to increase public awareness.

It’s important to note that there is no difference in practice, experience, or skill set between an RD and an RDN. It’s the same role, same qualifications—just a slightly longer title.

Licensure

Now, let’s complicate things further with the topic of licensure. Licensure is state-regulated, and it adds another level of qualification for Dietitians. When a Dietitian becomes licensed, they earn the title Licensed Dietitian (LD) or Licensed Dietitian Nutritionist (LDN).

Whether they’re called LD or LDN depends on the state—Texas uses LD, Massachusetts uses LDN, but the meaning is identical. Licensure matters because it identifies Dietitians as state-regulated nutrition professionals.

For example, a Dietitian with an RD or RDN credential may be required by their employer to obtain state licensure, as it makes them eligible for provider recognition by insurance companies. Licensed Dietitians can also offer Medical Nutrition Therapy (MNT), a key service that allows them to counsel patients with specific medical conditions like diabetes, hypertension, and kidney disease.

Here’s where it gets even more interesting: only licensed Dietitians are legally allowed to provide nutrition counseling in states that require licensure. This means that unlicensed Nutritionists cannot offer the same scope of services.

In states where licensure exists, it is a safeguard ensuring that the person providing medical nutrition advice has met a minimum standard of education and experience.

The Controversy Around Licensure

But wait—there’s controversy! Not everyone is on board with the idea of licensure. Some view it as a protectionist tool that limits competition for Dietitians, preventing others from entering the field.

In fact, a recent legal case brought this issue into the spotlight. A blogger without licensure was targeted for offering nutrition counseling, sparking a debate about the purpose and fairness of licensure.

Critics argue that licensure is simply a way for organizations like the Academy of Nutrition and Dietetics to monopolize the field and stifle competition. They claim that licensure prevents knowledgeable individuals—who may not have the formal credentials of a Dietitian but still possess valuable insights—from offering their services.

On the other hand, the Academy sees licensure as a necessary measure to protect public health. Just like doctors and dentists are licensed to ensure they’ve met a rigorous set of standards, the Academy argues that Dietitians should be held to similar criteria. After all, nutrition advice can have a profound impact on someone’s health, especially when it involves managing chronic diseases.

This debate highlights the tension between professional regulation and open competition. Should we prioritize public safety through licensure, or allow a broader range of voices to contribute to the nutrition space? It’s a tough question, and both sides have valid points.

How Does the RDN Fit Into This Puzzle?

So, where does the new RDN title fit into this already complex landscape? It’s important to remember that whether you’re an RD or RDN, the credentials and qualifications are exactly the same. The difference between these titles and a generic “Nutritionist” remains vast, especially in terms of education, experience, and scope of practice.

Licensure doesn’t change with the addition of the “Nutritionist” title to the RD credential. Whether someone is an RD or RDN, they still need to obtain licensure in states where it’s required.

The RDN title may help bridge some of the public’s confusion, as it emphasizes that Dietitians are also Nutritionists—but it doesn’t alter the underlying qualifications or responsibilities of the profession.

What Does This Mean for You?

If you’re a consumer, this information is crucial for understanding who you can trust with your nutrition advice. Here’s a quick takeaway:

  • If you want to ensure you’re working with a highly qualified professional, look for someone who holds the RD or RDN credential. Both titles indicate that the person has gone through rigorous education, training, and certification.
  • If licensure is required in your state, make sure your provider also holds the LD or LDN title. This means they’re legally recognized by the state as a qualified nutrition professional and are able to provide services like Medical Nutrition Therapy.
  • Be cautious when seeking advice from a “Nutritionist” without checking their qualifications. In many states, anyone can call themselves a Nutritionist, so it’s important to verify their education and credentials before taking their advice to heart.

The Bottom Line

At the end of the day, what really matters is not the letters after someone’s name, but their knowledge, experience, and ability to help you meet your health goals. Whether you’re working with an RD, RDN, or LD, make sure they have the credentials and expertise necessary to guide you in your nutritional journey.
