Choosing to become a dietician or a nutritionist is a big step. Both careers can be very rewarding. Not only can you earn a nice living, but you can also help others.

Understanding the difference between a dietician and a nutritionist can help you make this decision. While they might seem interchangeable, they are not. These are two different professionals with some similarities.

Before you decide which career is right for you, it’s important to understand both. Let’s look at what both are and the differences between a dietician and a nutritionist.

Dietician vs Nutritionist

What is a Dietician?

A dietician is a board-certified food and nutrition expert. They have the necessary education to provide advice about food, nutrition, and human health.

As a dietician, you will provide evidence-based medical nutrition therapy. It’s also common to provide nutritional counseling specific for each individual client you see.

There are several types of dieticians including:

Each of these careers is a bit different and may work in a different setting.

What is a Nutritionist?

While in many states anybody can be a nutritionist, regardless of education, other states require you to become a Certified Nutrition Specialist (CNS). With certification, you may have the ability to practice medical nutrition therapy, depending on your state.

You might also become a Licensed Dietician Nutritionist (LDN) in states, such as Florida, Illinois, Pennsylvania, Massachusetts, Maryland, and Alaska. This is a similar license as the CNS, but with a different name.

There is also such a thing as an uncredentialed nutritionist. This type of title is found in states that don’t require a certification. They may lack the training and expertise necessary to provide nutrition counseling. It’s best to become certified to ensure clients can see you have the training necessary to help them.

Dietician vs Nutritionist: The Differences

One of the main differences between a dietician and a nutritionist is found in the legal restrictions. You cannot call yourself a dietician without becoming registered with the Commission on Dietetic Registration (CDR). Technically, this makes you a registered dietician (RD).

Dieticians have more protection under the law. However, nutritionists are free from government regulation. In some states, you may need a license from the Board of Nutrition, but in other states, anybody can call themselves a nutritionist.

Along with the legal difference, there are a few other differences between a dietician and a nutritionist including:

While there are some differences between a dietician and a nutritionist, they are very similar careers.

Dietician vs Nutritionist: Choosing the Right Career

If you want to counsel people when it comes to a diet plan, you want to become a registered dietician. Those looking to diagnose and treat medical conditions or provide medical nutrition therapy should become a registered dietician.

In most states, a registered dietician is the only one of the two that can provide these services for individuals. While you can become a certified nutrition specialist, as a registered dietician, you will be able to do more for your clients. Even a CNS cannot prescribe nutrition therapy. Instead, they commonly teach the public about healthy diets and organize health programs.

Both careers are very rewarding options, but one may be better for you than the other. If you want to help individuals, become a registered dietician. If you prefer to design health programs for the public, become a certified nutrition specialist.
