Careers in Nutrition

University of Hawai‘i at Mānoa Food Science and Human Nutrition Program and Human Nutrition Program

If you are considering a career in nutrition, it is important to understand the opportunities that may be available to you. Both registered dietitians (RD) and nutritionists provide nutrition-related services to people in the private and public sectors. A RD is a healthcare professional who has credentials from the Commission on Dietetic Registration and can provide nutritional care in the areas of health and wellness for both individuals and groups. A nutritionist is an unregistered professional who may have acquired the knowledge via other avenues. RDs are nutrition professionals who work to apply nutritional science, using evidence-based best practices, to help people nourish their bodies and improve their lives.

Becoming a RD requires a Bachelor’s or Master’s degree in dietetics from an accredited program, including courses in biology, chemistry, biochemistry, microbiology, anatomy and physiology, nutrition, and food-service management. Other suggested courses include economics, business, statistics, computer science, psychology, and sociology. In addition, people who pursue this path must complete a dietetic internship and pass a national exam. Also, some states have licensure that requires additional forms and documentation. To become a dietetic technician registered you must complete an undergraduate dietetic program and pass a national exam. Forty-seven states have licensure requirements for RDs and nutritionists. A few remaining states do not have laws that regulate this profession.[1] Go to https://www.cdrnet.org/certifications to learn more.

Working in Nutrition

Registered dietitians (RDs)/registered dietitians nutritionist (RDNs) and nutritionists plan food and nutrition programs, promote healthy eating habits, and recommend dietary modifications based on the needs of individuals or groups. For example, an RD/RDN might teach a patient with hypertension how to follow the DASH diet and reduce their sodium intake. Nutrition-related careers can be extremely varied. Some individuals work in the government, while others are solely in the private sectors (i.e., private practice, worksite wellness, hospitals, outpatient clinics, etc). Some jobs in nutrition focus on working with elite athletes, while others provide guidance to patients with long-term, life-threatening diseases. But no matter the circumstance or the clientele, working in the field of diet and nutrition focuses on helping people improve their dietary habits by translating nutritional science and evidence-based recommendations into food choices.

In the public sector, careers in nutrition span from government work to community outreach. RDs who work for the government may become involved with federal food programs, federal agencies, communication campaigns, or creating and analyzing public policy. On the local level, clinical careers include working in hospitals and nursing-care facilities. This requires creating meal plans and providing nutritional guidance to help patients restore their health or manage chronic conditions. Clinical dietitians also confer with doctors and other health-care professionals to coordinate dietary recommendations with medical needs. Nutrition jobs in the community often involve working in public health clinics, cooperative extension offices, and HMOs to prevent disease and promote the health of the local community. Nutrition jobs in the nonprofit world involve anti-hunger organizations, public health organizations, and activist groups.

Nutritionists and dietitians can also find work in the private sector. Increased public awareness of food, diet, and nutrition has led to employment opportunities in advertising, marketing, and food manufacturing. Dietitians working in these areas analyze foods, prepare marketing materials, or report on issues such as the impact of vitamins and herbal supplements. Consultant careers can include working in wellness programs, supermarkets, physicians’ offices, gyms, and weight-loss clinics. Consultants in private practice perform nutrition screenings for clients and use their findings to provide guidance on diet-related issues, such as weight reduction. Nutrition careers in the corporate world include designing wellness strategies and nutrition components for companies, working as representatives for food or supplement companies, designing marketing and educational campaigns, and becoming lobbyists. Others in the private sector work in food-service management at health-care facilities or at company and school cafeterias. Sustainable agricultural practices are also providing interesting private sector careers on farms and in food systems. There are employment opportunities in farm management, marketing and sales, compliance, finance, and land surveying and appraisal.
