You may be asking what constitutes actual nutrition competence.
Maybe you’ve heard the phrases “nutritionist” and “dietitian” and aren’t sure what they imply.
The distinctions between dietitians and nutritionists, what they do, and the education necessary are discussed in this article.
It focuses on definitions and rules in the United States and only briefly touches on foreign ones.
What a dietitian does
A dietitian is a board-certified food and nutrition specialist in the United States and many other countries. They have a strong background in nutrition and dietetics – the science of food, nutrition, and its influence on human health.
Dietitians get considerable training to provide evidence-based medical nutrition treatment and nutritional advice suited to an individual’s requirements.
They are qualified to work in a variety of settings, such as hospitals, outpatient clinics, research institutes, and local communities, to mention a few.
Degrees and credentials required.
A Registered Dietitian (RD) or Registered Dietitian Nutritionist (RDN) must meet the standards established by regulating bodies such as the Academy of Nutrition and Dietetics (AND) in the United States or the Dietitians Association of Australia (1, 2).
Furthermore, in some countries, individuals can get the designation of “registered nutritionist,” which is synonymous with “registered dietitian” and needs certification from a regulatory authority.
These are professional bodies in each country that supervise the discipline of dietetics.
To be clear, the titles RD and RDN are interchangeable. RDN, on the other hand, is a relatively recent designation. Dietitians have the option of using either credential.
To obtain these certifications, aspiring dietitians must first get a bachelor’s degree or equivalent credits from a recognized institution or college program.
An undergraduate science degree is often required, including courses in biology, microbiology, organic and inorganic chemistry, biochemistry, anatomy, and physiology, as well as a more specific nutrition curriculum.
To be eligible for their RD board exams in the United States as of January 1, 2024, all dietetics students must also have a master’s degree (3).
All dietetics students in the United States must apply for and be matched with a competitive internship program certified by the Accreditation Council for Coursework in Nutrition and Dietetics in addition to formal education (ACEND).
Internships of a similar nature may be required in other countries.
Internships often expose students to 900–1,200 unpaid supervised practice hours throughout the four domains of practice, with strict adherence to competencies or specialized areas of study, and are supplemented by in-depth projects and case studies outside those hours.
Furthermore, before finishing the internship, the student must typically pass an exit test that mirrors the topic of the board exam. Completing these prerequisites qualifies them to take a board examination.
Finally, a dietetics student who passes their country’s board test can seek to become a registered dietitian.
Licensure
National board certification is required to get dietitian qualifications.
Furthermore, 13 states, including Rhode Island, Alabama, and Nebraska, require licensed dietitians to practice. The remaining states do not regulate this occupation or offer state certification or optional licensure (4).
Additional criteria, such as completing a jurisprudence test, may be part of the licensing procedure. This is intended to ensure dietitians follow a code of behavior to preserve public safety.
Dietitians must also maintain their professional growth by earning continuing education credits, which allows them to stay current in an ever-changing area.
Types of dietitians
Dietitians practice in four areas: clinical, food service management, community, and research.
Clinical dietitians work in the inpatient hospital environment. Outpatient dietitians may work at a hospital or clinic, although they often work with clients who are not admitted to inpatient care and are less unwell.
Inpatient and outpatient dietitians work with the medical team to address a variety of acute and chronic disorders. Dietitians in long-term care institutions may also oversee the diet of persons with serious illnesses who require continuing care.
They adhere to best practices and provide information on a person’s medical history and current state, including blood work and weight history. This enables them to identify urgent requirements and prioritize life-threatening illnesses.
Inpatient and outpatient dietitians also educate persons with unique requirements, such as those recovering from surgery, undergoing cancer treatment, or suffering from chronic conditions such as diabetes or renal disease.
They provide more in-depth nutritional counseling to achieve a nutrition-related goal in the outpatient environment.
Dietitians might also work in research hospitals, universities, or in food service management.
They can advocate for public policy and give knowledge in community settings such as schools or public health agencies such as Women, Infants, and Children (WIC).
Dietitians in food service managers oversee the provision of nutritionally appropriate food that complies with food safety rules within a big institution, such as a school district or military post.
A community dietitian can assist in designing and implementing population-based programs such as community cooking projects or diabetes preventive treatments. They can also campaign for public policy concerning nutrition, food, and health.
Dietitians who work at research hospitals, institutions, or universities are known as research dietitians. They work as part of a research team led by a principal investigator to implement nutrition-focused treatments.
After earning their qualifications and working in the industry, dietitians might choose to specialize in a specific area, such as pediatrics or sports dietetics.
Finally, dietitians may have private offices that provide services such as dietary advice.
They may also lecture in an academic or research setting or publish on nutrition-related issues. Others may work as health and nutrition experts or public speakers in the media.
Conditions dietitians treat
Dietitians are trained to provide nutrition treatment for various acute and chronic diseases. The location of their practice primarily determines the conditions they treat.
This means they may manage dietary issues caused by cancer or its treatment and work with a client to avoid the formation of diabetes.
Hospitals treat a broad spectrum of patients, including those who are clinically malnourished and those who require nutrition through feeding tubes.
Dietitians also care for clients who have bariatric (weight reduction) surgery or who have renal problems, as these people may have various dietary limitations and would benefit from specialized treatment to fulfill their bodies’ demands.
Eating disorder dietitians typically have additional training or education to handle this demographic. They collaborate with a group of psychotherapists and physicians to assist people in recovering from these conditions (5).
Chronic starvation (anorexia nervosa) or binge and purging (bulimia) are examples of eating disorders (5, 6).
Sports dietitians specialize in improving athletes’ nutrition for peak performance. Dietitians in this field may work in gyms or physical therapy clinics and with a sports team or dancing group (7).
What a nutritionist does
Although their educational background is similar to that of a dietitian, individuals in certain countries may interpret their title as “nutritionist” rather than “dietitian.”
In the United States, the term “nutritionist” can refer to someone with a wide range of nutrition qualifications and training.
Before a person may call oneself a nutritionist in more than a dozen states, specific standards must be satisfied. Furthermore, approved qualifications provide titles such as Certified Nutrition Specialist (CNS) (8).
Those who earn these qualifications are authorized to perform medical nutrition therapy and other elements of nutrition care in most states.
Many states, including Alaska, Florida, Illinois, Maryland, Massachusetts, and Pennsylvania, provide RDs and CNSs with the same state license, a Licensed Dietitian Nutritionist (LDN).
Anyone interested in diet or nutrition may call oneself a nutritionist in states where the word is not regulated. These folks might use their nutrition knowledge to create a food blog or work with clients.
However, because uncredentialed nutritionists often lack the skills and training required for medical nutrition treatment and nutrition counseling, trusting their advice may be hazardous (9).
Before contacting a nutritionist, you should check to see whether your state has restrictions on who may use this term.
Degrees and credentials required
No degrees or certifications are necessary to be a nutritionist in places where the world is not regulated. All you need is an interest in the subject.
The CNS or RD certificate may be necessary for states that require licensure.
CNS credential holders are advanced-degreed health professionals such as nurses or doctors who have pursued extra coursework, completed supervised practice hours, and passed an exam administered by the Board for Certification of Nutrition Specialists.
Conditions that CNSs and other nutritionists treat
CNSs have legal standing to treat health concerns in most states in the United States.
A dozen states also have laws governing the title “Licensed Nutritionist” or the more general “nutritionist.”
CNSs and licensed nutritionists can assist in treating any ailment that an RD would.
CNSs, like RDs, provide nutrition therapy, a specialized treatment used to manage or treat diseases or other ailments. CNSs may be in charge of community nutrition education initiatives as well.
Those without qualifications or licensing, however, may explore dietary practices that are outside the boundaries of orthodox medicine. Some of these techniques may have a solid scientific foundation, while others may not.
Giving dietary advice without the right expertise and training may be dangerous, especially when counseling those with health problems.
As a result, if you’re considering hiring a nutritionist, find out if they’re a CNS, have a state license or certification, or have another accreditation.
The bottom line
Dietitians and CNSs are board-certified food and nutrition professionals with considerable training and study.
Dietitians and nutritionists, such as CNSs, may need to satisfy extra qualifications to practice depending on where they live.
Dietitians and CNSs can use their knowledge in various contexts, such as hospitals, academic institutions, and food service management. Some work with specialized demographics, such as youngsters, athletes, or individuals suffering from cancer or eating problems.
Meanwhile, in the United States, several states regulate the term “nutritionist” but not others. As a result, anybody can claim to be a nutritionist in many places.
Though these designations might be confusing, keep in mind that experts with the titles “RD” or “CNS” have advanced degrees in nutrition.
