What Is Nutritional Science?

Nutritional science examines the connections between diet and health, with an emphasis on optimizing eating habits to meet an individual's nutritional needs. Bachelor's programs in nutritional sciences synthesize biology, chemistry, and social science, training students to analyze how food and medicine affect the body. Candidates gain foundational knowledge on concepts like catabolism (how the human body breaks down food) and anabolism (how the body uses derived nutrients to create and repair cells and tissues).

Nutritional science students cultivate communication skills needed for careers in research, fitness coaching, and health education. They also train in public policy and program management, which prepares them for occupations in food service, dietetics, pharmaceutical manufacturing, and global health.

Growing health concerns in the U.S. drive the demand for skilled nutritionists and health educators. In its 2016 report, the Centers for Disease Control and Prevention noted that, between 1988 and 2014, the adult obesity rate grew dramatically, averaging a 5% increase for Grade 1, 2, and 3 obesity. The CDC also reported growing numbers of adults with hypertension, hypercholesterolemia, and heart disease.

How to Choose a Bachelor's in Nutritional Sciences Program

Colleges and universities deliver bachelor's programs in nutritional sciences that fit the needs of diverse students, including working professionals and career changers. When researching schools, you should consider factors like tuition, course structure, and career services. This section examines some attributes of effective academic programs.


Higher education institutions need to maintain regional or national accreditation to confer valid degrees and certificates. Schools become nationally accredited through authorities supported by the Council for Higher Education Accreditation and the U.S. Department of Education. They receive regional accreditation from one of six organizations, depending on location. Bachelor's programs in nutritional sciences can also gain specialized accreditation from the Accreditation Council for Education in Nutrition and Dietetics.

Cost and Financial Aid

To minimize college debt, learners should enroll in schools that feature affordable tuition rates. Online bachelor of nutritional sciences programs routinely provide low per-credit tuition that ignores residency status. Students should clarify their school's tuition pricing, because some institutions charge part-time candidates higher rates than full-time learners. Financial aid should always be a strong consideration. The best colleges and universities offer institutional scholarships, fellowships, and grants.

Program Format

Program format greatly impacts the learning experience. Students should consider how synchronous or asynchronous classes integrate into their daily schedule. Most universities allow degree candidates to individually pace their schedules, while other schools operate a cohort learning format. In this latter structure, students take one or two classes at a time and advance through the degree plan at the same rate as their peers. Cohort learning fosters collaboration but may slow down program completion.

Concentration Options

Although bachelor's programs in nutritional sciences typically consist of similar core classes, students can personalize their curriculum by choosing electives and pursuing concentrations that support their career goals. Options often include dietetics, food science and technology, and community nutrition. Some schools even offer a pre-med track that focuses on prevention and treatment of acute and chronic diseases.

Student Resources

Colleges and universities that deliver academic resources significantly bolster their students' success during attendance and after graduation. Candidates should prioritize schools that offer personalized degree counseling, writing and subject tutoring, and networking opportunities through honor societies and campus groups. Well-funded libraries help students conduct research. Learners should also look for accessible career services, like internship-placement programs and resume-building workshops.

Bachelor's in Nutritional Sciences Program Admissions

This section examines the application requirements you can typically expect of bachelor's programs in nutritional sciences. You also receive an overview of the admissions process, including a general time frame of how long it takes to properly prepare and submit application materials.


Minimum GPA: First-time students can expect a 3.0 minimum GPA requirement, while transfer candidates typically need to satisfy a 2.0 minimum. Competitive bachelor's in nutritional sciences programs may require higher standards. Some schools accept students with inadequate GPAs if they demonstrate strong academic potential through standardized testing and relevant job experience. Prerequisite Coursework: At the bachelor's level, students do not usually need to fulfill prerequisite requirements to qualify for admission. However, dual-degree programs may operate this criteria. Common prerequisite topics for nutritional sciences include microbiology, nutrient metabolism, and social science perspective on food and nutrition. Students who complete prerequisite classes as part of an advanced high school curriculum or associate program can accelerate their bachelor's degree completion. Career Experience: Students with work experience in nutritional sciences can translate their professional achievements and career history into transfer credits. This benefit is particularly useful to distance learners, who can satisfy internship requirements without needing to complete summer residencies on campus. Like prerequisite coursework, career experience is a common entry requirement for five-year dual-degree programs.

How to Apply

Standardized Test Scores

Online bachelor's of nutritional sciences programs increasingly disregard standardized testing, opting for more holistic means of student evaluation. Similarly, colleges and universities typically do not require candidates who graduated from high school more than four years prior to submit ACT/SAT scores. Among institutions that do ask for test results, minimums vary so students should confirm this criteria with admissions counselors.

Personal Statement

Prospective students typically submit a one- to two-page personal statement that details academic preparation, relevant career experience, and professional goals. Also called a letter of intent, this essay allows schools to identify if an applicant's worldview and objectives align with the institutional mission. In lieu of a formal statement, some universities ask candidates to answer a series of short essay questions.

Recommendation Letters

Postsecondary schools typically ask applicants to submit 2-3 recommendation letters from professors, employers, mentors, and other individuals who can attest to their personal qualities and academic potential. Some institutions specify who may or may not write these letters. Certain schools prefer to contact recommenders directly through email or phone.


If your school requires SAT or ACT scores, consider allocating 2-3 months (or about 1,200 hours) to review content and prepare for the exam. You can view SAT scores online 13-15 days after the test date, and it takes an additional 10 day for the results to reach your school. ACT scores usually arrive within two weeks but can take up to eight weeks.

The application timeline greatly depends on your university's deadline. Higher education institutions usually set the early admission deadline in November and the regular admission deadline between January and March. Online bachelor's of nutritional sciences commonly operate rolling admissions, accepting applicants year-round. Once you identify the deadline, it is best to slot 4-6 weeks to prepare and submit the application materials. This window leaves plenty of time for you to write an evocative personal statement and your recommenders to craft complimentary letters. When in doubt, work with an admissions counselor to create a schedule that fits your needs.
