We all could probably eat a little better—whether that be cutting back on sugar and sodium or simply eating less processed foods. For the millions of Americans living with conditions such as hypertension or diabetes, having a healthy diet is paramount. However, one of the biggest barriers to this is a lack of knowledge. That’s where nutritionists come in. 

Nutritionists are experts in food and healthy eating habits, but learning these skills can be complicated.

Methodology for Fortune’s ranking of the best nutritionist certifications

There’s great news for those interested in the world of nutrition: the field is in high demand. In fact, according to the U.S. Bureau of Labor Statistics, demand for dietitians and nutritionists is growing at a rate of 7% over the next decade, and the median annual salary is just shy of $70,000. It is also important to keep in mind that to achieve this career status, individuals oftentimes need at least a bachelor’s degree as well as advanced training; each state also has different requirements for official licensure.

Even though the nutritionist industry is continuing to grow, there is no perfect pathway toward success. However, learning more about the nutritionist world through certification is a great place to start, especially if you aren’t certain if it’s the right career for you or if you just need a refresher on the basics. 

We reviewed 25 nutritionist certification programs and have included 10 of our top choices.

While a variety of factors were used in considering each category, these data points were used to overall judge the programs:

  • Price: 40%
  • Financing options: 10%
  • Lending partnerships: 10%
  • Scholarship opportunities: 10%
  • Military discounts and funding: 5%
  • Continuing education credit acceptance: 5%
  • Career coaching/mentorship/instructor support: 10%
  • Average annual search volume: 10%
    • We looked at the average number of times during a month that people search for each business school on Google, then converted it into a yearly metric to measure public perception and interest in a school and how it affected what school they were interested in attending.

Our expert panel 

We sought out those with thorough expertise in the nutritionist world for the creation of our ranking: 

By asking questions about the importance of nutritionist education, different types of educational pathways, and the skills needed to succeed, we hoped to better understand how to effectively guide those pursuing a career in the field. It’s noteworthy that neither expert was directly involved in ranking any programs.

Anyone can call themselves a nutritionist

Similar to the world of health coaching and other certificate programs, anyone can truly call themselves a nutritionist. However, as Painter notes, the nutritionist title is often correlated with both registered dietitians and certified nutritionist specialists.

“The nutrition professional is going to have advanced education, benchmark education, through bachelor’s degrees, through master’s degrees with standardized and structured information that provides safety but also efficacy in their recommendations to working one-on-one with clients,” Painter says. 

She adds that once one obtains the official licensure, which depends on the state, only then should they be suited to give personalized nutrition recommendations to clients in a clinical setting.

“Nutrition is a very nuanced space,” Painter says. “One right condition does not fit every patient. Having the ability to have critical thinking skills, the tactical knowledge of nutrition science, and also the understanding of mainstream and gold standard approaches to care, it’s very important for the safety and the health of the patient.”

In terms of skills, Painter says anyone looking to get into nutrition should have:

  • Excellent communication and listening skills
  • An ability to relate to people from different backgrounds
  • Interpersonal skills, such as empathy, compassion, and patience 
  • Problem-solving capabilities 
  • A deep interest in scientific knowledge, like nutrition science, biochemistry, and pathophysiology

Fighting nutrition misinformation

Routhenstein emphasizes that broad nutrition certifications focus more on holistic health like body, mind, and spirit. People with the training can be great at helping others take accountability when it comes to losing weight or learning how to eat healthy—when they do not have a past medical history.

On the other hand, clients on medication or with medical history should instead be seen by licensed dietitian nutritionists or others with a relevant academic background and clinical expertise.

“It’s important that when you have a medical diagnosis—you’re not just being seen by anyone, because they might not understand nutrition, they may just give you a bunch of supplements that counteract with your medications and can drive your kidney function down,” she says.

Both Routhensin and Painter say one of the most important things to the world of nutrition is curiosity and asking questions—not only about yourself but also about biology. Some questions to consider include:

  • What do you want to do with your career? 
  • Why do you want to help others? 
  • Why do certain foods affect human bodily functions differently from a biological standpoint? 
  • Why should someone eat more of something versus another thing?

Nutrition misinformation is running rampant in an era of social media dominance. In fact, a recent analysis of TikTok videos relating to diet and nutrition trends found that only 2% of the content was accurate. Because of this, Routhensin says it is more important than ever that experts are credentialed by a top governing body, such as the Academy of Nutrition and Dietetics Commission on Dietetic Registration.

Frequently asked questions

What exactly does a nutritionist do?

Nutritionists help individuals understand how eating affects everything they do—physically, mentally, and emotionally. They may provide advice on healthy eating habits by creating catered meal plans as well as setting short- and long-term goals. Nutritionists with simple certifications may provide generalized recommendations.

What is the difference between a nutritionist and a dietitian?

While anyone can call themselves a nutritionist (hence being able to get a nutritionist certification), not just anyone can claim to be a dietitian. The fields of study are similar—focused on food science and healthy eating—there are much more state regulations when it comes to dietitians. 

Do nutritionists make money?

Dietitians and nutritionists earn median annual salaries of about $70,000, according to the U.S. Bureau of Labor Statistics. Exact pay can vary dramatically depending on your role and educational experience.

What is the best qualification for a nutritionist?

While there is truly no best qualification for a nutritionist, registered dietitians and nutritionists typically have at least a bachelor’s degree—paired oftentimes with a master’s or PhD. Checking out your state’s educational and clinical hour requirements is a great place to start.
