A bachelor of science in nutrition online equips you with the skills needed for professional success. By earning an online nutrition degree, graduates can pursue many different careers, including nutritionist, health worker, and fitness instructor. The U.S. Bureau of Labor Statistics (BLS) projects that job growth in dieting and nutrition fields will grow by 15% between 2016 and 2026. Factors like obesity and the aging baby boomer population increase the need for nutritional services.

Earning a bachelor’s degree in nutrition science places you at the forefront of an evolving field. Many programs offer experiential learning opportunities to help you gain hands-on experience before graduating. Curriculum requirements such as capstone courses allow students to develop research projects that fit their career interests. Interacting with established professionals as part of an internship can help students refine their professional interests and goals. Some programs use a cohort format, requiring you to complete courses along with a group of peers. Other programs follow an asynchronous format that may allow more flexibility.

The following list includes examples of common courses students may encounter throughout their online nutrition degree.

Curriculum for an Online Bachelor’s in Nutritional Science

  • Food Science: In this foundational nutrition course, students explore the scientific properties of food, including the handling and preparation of those foods, often in a lab-like setting. Course activities may include planning and making recipes that reveal the chemical interactions of nutrients and examining the latest food technology.
  • Fundamentals of Microbiology: Students learn the properties and principles of microorganisms, such as bacteria, viruses, and fungi. They use this knowledge to form a deeper understanding of application in ecology, health, and related fields. Students may also study how microorganisms affect food safety and sanitation in the context of food production and distribution.
  • Nutrition Education: With a focus on different types of audiences, students learn how to develop and deliver an effective nutrition education curriculum. Course content addresses current issues and trends in nutrition and the potential behavioral barriers that dieticians might face with individual clients, community members, or other groups.

How Long Does It Take to Get an Online Bachelor’s in Nutritional Science?

An online bachelor's in nutritional science requires an average of at least 120 credit hours and takes between three and four years to complete. However, a variety of program characteristics impact the amount of time needed to complete an online degree, including the number of required credit hours, full- and part-time enrollment options, and whether courses may be taken in a self-paced or cohort-based format.

Students in cohort-based programs typically attend virtual class sessions during the evenings or on the weekend and complete courses within the same time frame as other students in their cohort. Some online programs may also require students to come to campus to complete lab-based science courses like microbiology, which can also extend degree completion time.

School accreditation by a national or regional agency typically indicates a high level of quality in terms of curriculum, instruction, and student outcomes. Some schools earn both national and regional accreditation, while others have earned only one or the other. Regional accrediting agencies usually review state or nonprofit universities. Technical and vocational programs, religious institutions, and for-profit organizations tend to hold national accreditation. Both types of accrediting agencies assess higher education institutions based on a set of quality standards. However, many schools only accept transfer credits from schools with regional accreditation.

Students can also look for accredited online nutrition degrees recognized for meeting professional-level standards at a program level. Search for nutritional science programs with recognition from the Accreditation Council for Education in Nutrition and Dietetics Academy of Nutrition and Dietetics (ACEND), one of the foremost accrediting agencies for related programs in the country.

The U.S. Department of Education (the ED) oversees a variety of federal agencies that provide various functions, including managing federal student aid and promoting anti-discrimination policies. The ED also approves organizations to assess schools and programs for quality standards through accreditation. The Council for Higher Education Accreditation (CHEA), a membership organization, also approves accrediting agencies. Both the ED and CHEA maintain lists of accredited schools on their respective websites.
