What Is Nutrition Science?

Nutrition science examines nutrition processes, the various chemical compounds found in foods, and how components like protein, energy, and vitamins affect human health and disease. Learners in a bachelor's in nutrition science program study multidisciplinary topics related to social and life sciences, including behavioral psychology, mental health, and physiology.

What Is a Bachelor's in Nutrition Science Degree?

Prospective nutrition science students can choose between an associate or a bachelor's program in nutrition science. While an associate degree qualifies graduates for some entry-level support roles, it does not qualify graduates for industry credentials. Graduates with a bachelor's degree qualify for more roles as well as industry licenses and certifications.

Bachelor's students can often specialize in specific areas of nutrition science to prepare for niche roles working in nutrition and fitness, nutrition and food safety, nutrition management, or agricultural food science.

Choosing an Online Nutrition Degree Program

Prospective students should consider several factors before selecting an online nutritionist degree, such as a program's cost, size, and type. Typically, in-state public schools cost less than private schools and out-of-state public schools. However, some programs allow all online students to pay in-state tuition rates regardless of residency.

Prospective students should consider several factors before selecting an online nutritionist degree, such as a program's cost, size, and type.

Additionally, students should consider the size of a school and program. Some students may prefer the more individualized attention a smaller school provides, while learners looking to specialize in an area of nutrition science may prefer the larger variety of specializations and programs that bigger schools often offer.

Distance learners should also research whether a program is fully online or has some on-campus requirements. Students who don't live near their prospective schools should ensure that they can meet all on-campus requirements.

Accreditation for Online Nutrition Degree Programs

Accreditation indicates that a school meets high standards with respect to faculty qualifications, student learning outcomes, and academic rigor. Accreditation benefits students in several ways. For instance, only students attending an accredited program qualify for federal financial aid, and many schools only accept and recognize credits and degrees from regionally accredited institutions. Additionally, many employers prefer to hire candidates with accredited degrees.

Students can verify a school's accreditation status through the U.S. Department of Education and the Council for Higher Education Accreditation.

Schools may receive regional or national accreditation, with regional accreditation generally considered the more prestigious of the two. Students can verify a school's accreditation status through the U.S. Department of Education and the Council for Higher Education Accreditation.

Programs within a school may also receive accreditation. Nutrition science degree programs may receive accreditation through the Accreditation Council for Education in Nutrition and Dietetics. Students may need to hold a degree from an accredited program to qualify for licensure or certification.
