Career Pathway Listen to this section
Becoming a dietitian or nutritionist usually requires at least a bachelor's degree in dietetics, foods and nutrition, food service systems management, or a related area. A master's degree can help some workers to advance their careers, particularly in career paths related to research, advanced clinical positions, or public health.
Requirements differ by location, but many states require dietitians and nutritionists to be licensed. Additionally, although not required by law, many employers prefer to hire dietitians and nutritionists who have been certified as Registered Dietitians by the American Dietetic Association. To maintain a Registered Dietitian status, workers must complete at least 75 credit hours in approved continuing education classes every 5 years.

high school credential
Typical degree for an entry-level position: Bachelor's degree ?
High school students interested in becoming a dietitian or nutritionist should take courses in biology, chemistry, mathematics, health, and communications. Following high school, students will need to enter into a bachelor's degree in dietetics, foods and nutrition, food service systems management, or a related area. College students in these majors take courses in foods, nutrition, institution management, chemistry, biochemistry, biology, microbiology, and physiology. Other suggested courses include business, mathematics, statistics, computer science, psychology, sociology, and economics.
Dietitians and nutritionists interested in advancing to positions related to research, some clinical specialties, or public health oversight will have better employment prospects if they obtain a master's degree. Nutritionists interested in research should also take a heavier concentration of courses that emphasize chemistry and biochemistry laboratory techniques.

On the Job
Role Models
Nature of the Work
Dietitians and nutritionists plan food and nutrition programs, and supervise the preparation and serving of meals. They help prevent and treat illnesses by promoting healthy eating habits and suggesting diet modifications, such as less salt for those with high blood pressure or reduced fat and sugar intake for those who are overweight.
Dietitians run food-service systems for institutions such as hospitals and schools, promote sound eating habits through education, and conduct research. Major areas of practice include: clinical, community, management, and consultant dietetics, and nutritional research.
- Clinical dietitians provide nutritional services for patients in institutions such as hospitals and nursing homes. They assess patients' nutritional needs, develop and implement nutrition programs, and evaluate and report the results. They also confer with doctors and other healthcare professionals in order to coordinate medical and nutritional needs. Some clinical dietitians specialize in the management of overweight patients, care of the critically ill, or of renal (kidney) and diabetic patients. In addition, clinical dietitians in nursing homes, small hospitals, or correctional facilities also may manage the food-service department.
- Community dietitians counsel individuals and groups on nutritional practices designed to prevent disease and promote good health. Working in places such as public health clinics, home health agencies, and health maintenance organizations, they evaluate individual needs, develop nutritional care plans, and instruct individuals and their families. Dietitians working in home health agencies provide instruction on grocery shopping and food preparation to the elderly, individuals with special needs, and children.
- Management dietitians oversee large-scale meal planning and preparation in healthcare facilities, company cafeterias, prisons, and schools. They hire, train, and direct other dietitians and food service workers; budget for and purchase food, equipment, and supplies; enforce sanitary and safety regulations; and prepare records and reports.
- Consultant dietitians work under contract with healthcare facilities or in their own private practice. They perform nutrition screenings for their clients, and offer advice on diet-related concerns such as weight loss or cholesterol reduction. Some work for wellness programs, sports teams, supermarkets, and other nutrition-related businesses. They may consult with food-service managers, providing expertise in sanitation, safety procedures, menu development, budgeting, and planning.
- Nutritional researchers work in research settings. They investigate how the nutritional makeup of food is altered by various cooking and storing methods. Nutritional researchers may also run experiments to learn more about how people react to different nutrients and how their nutritional requirements change under unusual circumstances, like prolonged time in zero gravity on board the international space station.
Increased interest in nutrition has led to additional opportunities in food manufacturing, advertising, and marketing, in which dietitians analyze foods, prepare literature for distribution, or report on issues such as the nutritional content of recipes, dietary fiber, or vitamin supplements.
Work Environment
Dietitians and nutritionists usually work in clean, well-lighted, and well-ventilated areas. However, those who directly oversee meal services may spend significant amounts of time in hot, congested kitchens. Many dietitians and nutritionists are on their feet for much of the workday.
Most full-time dietitians and nutritionists work a regular 40-hour week, although some work weekends. Part time work schedules are also common for dietitians and nutritionists; in 2006 approximately one in three worked part time.
Nutritionists involved in research may spend a large portion of their time in laboratories or analyzing data in front of a computer.
