Nutrition Emphasis

The Nutrition emphasis gives you lots of options. It combines medicine, food chemistry, cell biology and biochemistry with a focus on nutrition and foods. It also prepares you to enter careers in the food and health industries or pursue graduate studies and research.

Course topics include nutritional biology and metabolism, food science and safety, nutrition assessment, and therapeutic diets. Graduates may also work as nutritional advisers in schools, wellness centers, the U.S. military or nonprofit organizations. Some of these jobs may require an advanced degree or certification, but with a bachelor’s degree in Nutritional Sciences, you’ll have plenty of paths toward your goals.

Dietetics Emphasis

The Dietetics emphasis provides the first step toward becoming a registered dietitian nutritionist (RDNs), nutrition and dietetics technician, registered (NDTR) or nutrition professional. You’ll gain a strong foundation in the sciences and take a wide variety of food and nutrition courses, preparing you to work in disease prevention and management, community health and wellness, counseling, food science, and the food industry. Many of these careers require or prefer the RDN or NDTR credential.

To become an NDTR, gradutates must sit for the NDTR Credentialing Exam. Completing the Dietetics emphasis qualifies students to sit for the exam.

To become an RDN, graduates must complete an accredited dietetic internship. These competitive programs can be started after graduation. A national exam is then required as the final step to earn the RDN credential.
