The Bachelor of Science degree in Nutrition and Dietetics prepares graduates for rewarding careers as nutritionists, dietitians, wellness experts, food service managers, and community counselors. The four-year, 120-credit program provides students with a basic liberal arts and strong science education, and the knowledge required to understand nutrition. Students take courses in biology, chemistry and statistics and master such subjects as normal nutrition, medical nutrition therapy, community nutrition, institutional food service management, cultural and social aspects of food, energy and exercise, and food technology. The program also prepares students to apply their knowledge of nutrition to promote healthy eating and lifestyle choices among individuals and groups as well as those with special nutritional needs. The goal of the program is to develop a graduate who meets the foundation knowledge and skills required by the Academy of Nutrition and Dietetics.

The B.S. degree includes the Didactic Program in Dietetics (DPD). The DPD at LIU Post is currently granted full accreditation by the Accreditation Council for Education in Nutrition and Dietetics (ACEND) of the Academy of Nutrition and Dietetics. Upon successful completion of the program, students are eligible to apply to an accredited supervised practice program such as the Dietetic Internship (DI) or to obtain an entry-level position that does not require the Registered Dietitian Nutritionist (RDN) credential. Students must complete both the B.S. degree and an ACEND- accredited DI to be eligible to sit for the national examination for Registered Dietitian Nutritionists.

The undergraduate nutrition program at LIU Post meets the academic requirements to be a Certified Dietitian/Nutritionist (CDN) in New York State. Successful completion of a DI and the RDN examination qualifies individuals to be a New York State CDN.
