Nutrition Licensure and Certifications

Private nutritionists in many states do not have to meet specific licensure requirements, but becoming a registered dietitian or nutritionist requires licensure in most parts of the United States. Individuals without a license cannot promote themselves as a nutritional professional.

To become a registered dietitian, students need a bachelor's degree in nutrition, dietetics, or a related field from a program approved by the Accreditation Council for Education in Nutrition and Dietetics. These accredited programs integrate relevant coursework, practical experience, and research to prepare graduates for nutrition careers.

To work as a registered dietitian, candidates must meet requirements established by the Academy of Nutrition and Dietetics Commission on Dietetics Registration (CDR). CDR offers credentials for registered dietitians, registered dietitian nutritionists, dietetics technicians, and nutritionist technicians.

However, even with a certification through CDR, nutrition professionals may need to meet additional state requirements.

Nutrition professionals can earn voluntary certifications to indicate expertise in subfields. For example, professionals can obtain a certification as a clinical nutritionist through the Clinical Nutrition Certification Board, become a certified nutrition coach from the National Academy of Sports Medicine, or earn a certification as a nutrition consultant from the American Association of Nutritional Consultants.

Additionally, the National Association of Nutrition Professionals offers two credentials for nutritionists. Holistic nutritionists can earn a board certification or become a certified nutrition professional.

Interview With a Nutrition Major

Registered Dietitian, Instructor of Biomedical Sciences Missouri State University

Portrait of Daniela Novotny

Daniela Novotny

Daniela Novotny is a registered dietitian and instructor of biomedical sciences at Missouri State University. She also works at MSU's Health and Wellness Center as a dietitian and an employee wellness consultant. She has worked in many realms of dietetics, including clinical nutrition and nutritional counseling. She has a BS in dietetics and an MS in health promotion and wellness management. She is currently working on her doctorate in health sciences from A.T. Still University.

What skills are essential in this occupation?

Key skills in the nutrition/dietetics profession include communication, being up to date in the research related to your particular area, and having a true passion for improving the health of individuals and communities. Of the three, passion is probably the most important. With passion comes a desire to communicate effectively.

What advice would you give recent graduates seeking a job in this field?

Be open to any and all experiences. While you may not get the "dream" job right out of your internship, you will gain valuable experiences no matter where you work. Learn what you can from each situation and position.

Another piece of advice I would give is to think outside of the box. While jobs are often posted for dietitians, there may be other positions that are options for you as well — health educators, wellness trainers, etc. Keep your eyes and ears open for positions that involve the healthcare field.

Do you have any interview tips for job seekers?

The main tip I have for interviews is to thoroughly research the position and the company. By showing the interviewers that you have done your research on the company, you will stand out from those who did not prepare as well.

Other tips: ask a few good questions — by good, I mean ones that are not answered on their website — and send a thank-you note. It's old-fashioned, but it can get you remembered. Who doesn't like a thank-you card?

How much time do you spend working with other health professionals?

I spend a lot of time working with other health professionals. I work at an outpatient clinic — the Health and Wellness Center at Missouri State University — and I am the only dietitian there. As a result, I communicate with nurses, nurse practitioners, and physicians each time I work at the clinic.

What types of patients do you most commonly work with?

Working for a university health and wellness center, I am able to see a wide array of patients. I work with both employees and students, and each week is a new experience. Recently, I have seen patients for weight loss, weight gain, IBS, celiac disease, iron deficiency anemia, hypertension, hyperlipidemia, and eating disorders.

How important is an advanced degree for a nutritionist?

Due to the profession moving toward requiring a master's degree for eligibility to sit for the RD exam, it is becoming more important. Also, research suggests that dietitians/nutritionists who have advanced degrees earn about $5,000 more per year.

Having an advanced degree can also help with being a more competitive applicant for a position. Finally, there are some areas in dietetics that likely benefit from a dietitian/nutritionist having more education.

How has this field evolved since you started — especially with the recent nationwide shift of focus on school nutrition and childhood obesity?

I have seen more and more employee wellness programs pop up over the last 10 years. Positions like health educators and wellness coaches were not common until the past decade or so.

Additionally, I believe that more consumers are aware of dietitians/nutritionists and our unique roles and education. The job outlook is strong, yet our work is cut out for us as the health of the nation continues to decline.

How do you keep updated on recent research and technology? What does continuing education look like to you?

I am a member of the Academy of Nutrition and Dietetics and I regularly check the Evidence-Analysis Library for the information. The journal published by the Academy and quarterly newsletters are great sources of information. I am also a member of several dietetic practice groups that send out monthly or quarterly newsletters.

I try to read as much as I can, but I will be honest in saying there aren't enough hours in the day to stay up to date on everything. My main continuing education experiences include graduate courses (I am working on my doctorate), conference participation, and attendance at local dietetic association meetings and workshops.
