Nutritionist (Dietician)

The classic adage “you are what you eat” is easy to understand, yet the state of nutritional health in the United States indicates that the message has not gotten through to the majority of the population. The most recent data available from the Centers for Disease Control (CDC) as of 2022 shows that 42.4 percent are obese and lack adequate sources of healthy nutrition in their diets (CDC).

Fewer than one in ten children and adults consume the recommended daily amount of vegetables, and poor nutrition is a leading cause of two of the deadliest and most preventable diseases in adults: obesity and heart disease (CDC 2021).

In an attempt to be proactive about their health, the Boston Medical Center estimates that 45 million Americans annually turn to diets, of which over 50 percent are fad diets that promise dramatic results in weight loss but are statistically shown to be ineffective in sustaining long-term healthy habits. With the weight loss industry netting a record profit of around $71 billion dollars per year (CNBC 2021), it is clear that many people struggle to understand what kind of food to eat to reach their optimum level of health. 

Oversaturated with so much conflicting information about how to live a healthy lifestyle, who can people trust to learn how to eat well and live healthier, happier, and longer lives? The answer is nutritionists and dietitians. 

While medical science provides information on what nutrients are needed for general health, nutritionists decipher and tailor this information for an individual’s unique health needs. Nutritionists teach people how to care for their health by empowering them with diagnostic health assessments, individualized meal plans, and dietary counseling.

Considering the stats on U.S. obesity rates, it’s not surprising that nutrition is one of the fastest-growing careers in the United States. The Bureau of Labor Statistics estimates the demand for this profession to increase 11 percent nationally, leading to the creation of approximately 7,800 new positions between 2020 and 2030 (BLS 2021). 

Requiring a bachelor’s degree, supervised training, and licensure in most states, a career as a nutritionist can be rewarding for those with an interest in the concept of “food as medicine” and who enjoy helping people live healthier lives.

Nutritionist Specializations & Degree Types

A licensed nutritionist typically holds a bachelor’s degree in dietetics (the study of the practical applications of nutrition) or a field such as nutritional science. Related disciplines include clinical nutrition, foods and nutrition, and public health nutrition. These involve studies in biology, chemistry, nutrition, and psychology. Clinical internships are frequently part of nutrition program curriculums and require several hours of supervised training. 

Nutritionists with advanced degrees or specializations can position themselves to work in a specific area of the field, be an integral part of dietetic academic research, hold more leadership roles in healthcare, and possibly earn higher salaries. 

The following is a list of specializations offered by the Commission on Dietetic Registration, a leading credentialing organization in the field of dietetics: 

  • Gerontological nutrition
  • Oncology nutrition
  • Obesity and weight management
  • Pediatric nutrition
  • Pediatric critical care nutrition

Nutritionist Program Accreditation

Accreditation organizations measure and verify the educational quality of academic programs. An accredited institution has proven itself to meet high academic standards for educational rigor and quality. Without accreditation, students, staff, faculty, and employers seeking to employ nutritionists cannot be certain of the level of academic rigor and professionalism a program offers. Students applying for federal aid in the United States can only attend colleges or universities with regional or national accreditation.

Specific programs or entire institutions can be accredited by programmatic, regional, or national accreditation organizations. Programmatic accreditation in the field of dietetics is given by four organizations: the Accreditation Council for Education in Nutrition and Dietetics (ACEND), which is part of the Academy of Nutrition and Dietetics (AND) and overseen by the Association of Specialized and Professional Accreditors (ASPA). 

Public health degree programs may hold programmatic accreditation through the Council on Education for Public Health (CEPH). As previously mentioned, the Commission on Dietetic Registration is a leading credentialing organization for the field of dietetics and verifies specialization certifications for nutritionists. 

There are several reputable regional accreditation agencies that are all approved by the Council for Higher Education Accreditation (CHEA).

How Long Does it Take to Become a Nutritionist?

Education and experience are major factors to consider when calculating the time to become a nutritionist. Pursuing qualifications at a full- or part-time pace is another factor that can affect the time it takes to become a nutritionist. 

Nutritionist positions require a bachelor’s degree in nutrition science or a related field which can take four to five years and 1,200 hours of supervised practice (approximately 30 weeks). Coordinated bachelor’s degree programs in nutrition shorten the completion timelines by allowing students to earn credit and supervised hours concurrently.

A would-be nutritionist with a high school diploma needs four to five years to earn a bachelor’s degree in nutrition science or dietetics and gain the required 1,200 supervised hours of experience through an internship for RDN certification. A person with an associate’s degree or a bachelor’s in a non-science-related field may require two to three years to complete the coursework and internship experience to become qualified as a certified RDN.

Pursuing advanced degrees in nutrition can take anywhere from two to three years for a master’s degree and up to seven years for a doctoral degree for bachelor’s degree holders.

How To Become a Nutritionist – Step-by-Step Guide

Step 1: Graduate from High School or Earn a GED

Earning a high school diploma is a basic requirement for many rewarding careers and is an admissions requirement for two- and four-year degree programs at colleges and universities. Taking courses in anatomy and physiology, biology, and chemistry can help high school students prepare for college-level work in nutrition science.  

Step 2: Earn a Bachelor’s Degree in Nutrition or a Related Field (Four Years)

Entry-level positions in nutrition require bachelor’s degrees in nutrition science, dietetics, or a related field of science. Coordinated bachelor’s degree programs allow students to double-dip by participating in internships that earn them college credit and hours that count towards the 1,200 hours of supervised experience for the RDN credential. 

Step 3: Gain Work Experience in the Field (One Year or More)

Depending on state licensure requirements, professionals can begin their careers through unpaid or paid, supervised experience with entry-level positions in nutrition.

Step 4: Pursue Certification or Specialization (Less Than One Year)

If not already completed, the next logical step is to apply and take the exams to become an RDN. Other specializations and licensure certifications are available for those already in possession of an RDN such as licensed dietitian nutritionist (LDN), and certified diabetes educator (CDE).

Step 5: Earn a Master’s or Doctoral Degree (Optional, Two to Five Years)

Advanced levels of education allow nutrition professionals to immerse themselves in specialized knowledge and gain experience and notoriety as leading experts in the field. Starting January 1, 2024, a master’s degree will be required in order to earn an RDN credential.

What Do Nutritionists Do?

Nutritionists require specific skills and qualifications to help people eat healthfully, prevent disease, and manage medical conditions. Job responsibilities and skills include: 

  • Identifying nutritional risk factors
  • Designing tailored plans for individual health goals including weight loss, weight gain, and blood sugar management
  • Staying informed of state, federal, and tribal regulations and health initiatives
  • Helping patients set and maintain short- and long-term health goals and form healthy habits
  • Informing nutrition policy-making for public institutions (e.g. schools, hospitals, long-term care facilities) and businesses 
  • Developing educational materials for at-risk populations
  • Demonstrating cultural competence for persons of all socioeconomic backgrounds
  • Working with patients in a variety of healthcare settings: hospitals, schools, long-term care facilities, and private practices

Nutritionist Certifications & Licensure

Certification and licensure requirements for nutritionists vary by state and several states require a license in order to practice. Many nutritionists opt to pursue the registered dietitian nutritionist (RDN) credential since the qualifications required for state licensure are often the same. 

RDN is a nationally-recognized credential that is administered by the Commission on Dietetic Registration, the credentialing agency for the Academy of Nutrition and Dietetics (AND). RDNs are required to complete a bachelor’s degree and a dietetic internship of 1,200 hours of supervised experience. Coordinated programs accredited by ACEND offer both a bachelor’s degree and supervised experience through internships. Graduates of these programs can streamline the process by earning RDN certification. 

It should be noted that starting on January 1, 2024, candidates for an RDN credential will need to have a master’s degree. 

Licensed nutritionists are also distinguished by the following certification credentials: 

  • RDN: Registered Dietician Nutritionist
  • LDN: Licensed Dietician Nutritionist
  • CDE: Certified Diabetes Educator

Certified RDN credential holders must recertify every five years by earning 75 continuing education credits. 

Master’s or doctoral degree-holders in nutrition or dietetics with 1,000 hours of supervised experience can apply to take the Certified Nutrition Specialist (CNS) exam in order to distinguish their advanced levels of expertise. This credential is given by the Board for Certification of Nutrition Specialists. CNS holders have advanced degrees and must be able to prove 1,000 hours of supervised clinical experience.

How Much Do Nutritionists Make?

Bachelor’s degree holders in nutritional science or dietetics holding RDN certification are qualified for entry-level positions in nutrition or dietetics. Aspiring nutritionists must complete 1,200 hours of supervisory experience if a state requires RDN or similar proof of professional competence requirements for state licensure. 

The average annual salary for the 66,330 dietitians and nutritionists in the US is $64,150 per year (BLS May 2020). The percentiles for wages are:

  • 10th percentile: $39,840
  • 25th percentile: $51,700
  • 50th percentile (median): $63,090
  • 75th percentile: $77,180
  • 90th percentile: $90,000

Nutritionists Career Alternatives

Here are a few alternatives to a career as a nutritionist. 

Become a Genetic Counselor

Genetic counselors have a combination of counseling and science training that makes them uniquely suited to support and advise patients through the genetic testing process. In addition to explaining complicated testing to clients in layman’s terms, they must also help clients navigate the results and determine the next steps required. 

  • Typical Education: Master’s degree 
  • Licensing or Certifying Organization: American Board of Genetic Counseling (ABCG)

Become an Athletic Trainer

Athletic trainers can evaluate athletic injuries, apply supportive devices or tape, provide emergency care during a sports event, and write and implement rehabilitation plans. They work for sports teams, hospitals, clinics, rehabilitation centers, or anywhere you would find athletes. 

  • Typical Education: Bachelor’s degree (required for certification)
  • Licensing or Certifying Organization: Board of Certification for the Athletic Trainer (BOC)

Become a Health Educator

Health educators implement comprehensive education plans within targeted communities with the objective of improving health outcomes. These plans can be on a variety of topics including obesity, nutrition, vaccines, and fitness. In order to craft these plans, health educators survey communities through interviews or questionnaires. Upon completion of the program, participants are surveyed again to measure outcomes. 

  • Typical Education: Bachelor’s degree
  • Licensing or Certifying Organization: National Commission for Health Education Credentialing (NCHEC)
