In the U.S. and many other countries, a board-certified food and nutrition specialist is called a dietitian. These practitioners have a strong background in nutrition and dietetics—the science of food and its impact on human health. They are qualified to work in various settings, such as hospitals, outpatient clinics, research institutions, and local communities.
A dietitian's duties vary depending on their role and practice setting. However, their scope of work typically involves the following:
- Identifying patients' nutritional requirements
- Making food plans and modifying them as needed
- Giving nutritional advice to individuals and groups
- Maintaining a record of each patient's progress
Types of dietitians
There are several types of dietitians in the U.S., and knowing their types will help you choose the best one near you.
- Community dietitians: Dietitians in the community teach people about nutrition. They could work for community centers, corporate wellness initiatives, gyms, or a health maintenance organization (HMO). These experts strive to educate the public on how to avoid illness or disease through adequate eating.
- Clinical dietitians: Clinical dietitians develop and maintain dietary programs for hospital patients or nursing home residents. These experts may also operate in inpatient or outpatient clinics. They collaborate with doctors and nurses to provide individualized nutrition plans.
- Consultant dietitians: Some dietitians may be consultants. They may have a private practice or operate as an independent contractor for a healthcare facility. They develop individual dietary plans. They may assist customers with weight loss or build nutrition regimens for people with chronic conditions such as diabetes.
- Management dietitians: A management dietitian is typically required to oversee food selection and preparation in extensive healthcare facilities, schools, and prisons. These specialists may also ensure adherence to hygienic requirements and review the nutritional values of every meal provided.
- Research dietitians: A research dietitian analyzes the dietary needs of various groups of people. These experts also research the biological and chemical reactions of the body to different foods and diets. They could work for a university, a medical research facility, or a food processing factory.
Education, licensure, and certification for dietitians in the United States
A registered dietitian (RD) or registered dietitian nutritionist (RDN) needs to fulfill the requirements set forth by regulatory organizations like the Academy of Nutrition and Dietetics (AND) in the United States or the Dietitians Association of Australia.
Furthermore, in some countries, individuals can obtain the designation of a registered nutritionist, which is synonymous with a registered dietitian and needs certification from a regulatory authority.
Aspiring dietitians must first get a bachelor's degree or equivalent credits from a recognized institution or college program. An undergraduate science degree is typically required, which includes courses in microbiology, organic and inorganic chemistry, biochemistry, anatomy, biology, and physiology, as well as more specific nutrition coursework.
All dietetics students must also have a master's degree to be eligible for their RD board exams in the United States after January 1, 2024.
In the United States, all dietetics students must apply for a competitive internship program certified by the Accreditation Council for Courses in Nutrition and Dietetics (ACEND) and formal coursework. Furthermore, before completing the internship, the student must generally pass an exit exam 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.
What are the different subspecialties of dietitians?
A registered dietitian near you may specialize in nutrition and planning for a specific community or health need. They may concentrate on nutrition for youngsters, seniors, athletes, or persons with unique health concerns that alter their dietary needs. A registered dietitian can pursue additional credentials in a variety of fields, including:

They give medical nutrition therapy, which is essential to healing these children.

They create nutrition regimens that cover children's general growth and development needs and particular needs and circumstances.

A licensed dietitian can obtain this certification from the Certification Board for Diabetes Care and Education (CBDCE) in the United States.
What is the primary difference between a dietitian and a nutritionist?
The key difference is in their education and training. Dietitians are certified healthcare professionals who must complete specific educational and licensing requirements. They are experts in personalized eating plans and using food to support health. Visits to a dietitian are often covered by insurance, as they are recognized as medical providers.
A dietitian near you can be found working in various settings, such as:
- Hospitals and clinics
- Nursing homes
- Community health centers, gyms, and recreation centers
- Foodservice and beverage companies
- Pharmaceutical companies
- Government agencies
On the other hand, nutritionist is a general title with no formal requirements. Since anyone can call themselves a nutritionist, insurance doesn't typically recognize them. While some nutritionists may have education or experience in diet and food science, others might only be interested in healthy eating.
Where you go for nutrition advice matters, especially if you have specific health needs. A dietitian is generally the best choice for reliable, evidence-based advice.
That said, some nutritionists may still provide valuable insights. If you decide to consult a nutritionist, it's wise to ask about their education and experience first to better understand their background. Don't hesitate to inquire, as your health is important, and placing it in knowledgeable hands is essential.

Examining dietary habits in San Francisco
The Occupational Employment and Wage Statistics report by the U.S. Bureau of Labor Statistics indicates that as of May 2022, about 1,040 licensed dietitians and nutritionists were legally practicing in the metropolitan area of San Francisco-Oakland-Hayward in California.
The San Francisco Health Improvement Partnership published a report on the dietary habits and health status of San Francisco residents. According to this report, in 2017, nearly 70% of low-income pregnant women enrolled in the San Francisco Women Infants and Children (WIC) Eat SF program acknowledged consuming fruits and vegetables less than five times daily, as the SFDPH (San Francisco Department of Public Health) nutrition services director reported.
Furthermore, a concerning statistic revealed that at least one in ten San Franciscans failed to meet the recommended water intake during meals, resulting in about 614 preventable hospitalizations for dehydration in 2016 alone.
The issue of excessive consumption also surfaced, with over 40% of San Franciscans admitting to eating fast food weekly over the past five years. Demographic variations indicate that younger adults and males are twice as likely to indulge in fast food, and the trend is particularly prominent among those aged 25 to 44. The data from 2014 to 2016 suggested that while 54% of people between 25 and 44 consumed fast foods at least once weekly, the numbers were comparatively lower among adults over 65 (19%). Men in the state (50%) were more inclined to lean towards fast foods than women (37%).
