Life Span Nutrition

Life span nutrition coursework investigates how age affects food and nutrient needs, health, and overall wellness over the course of a human life. Students study nutrition in infants, children, adults, and the elderly. They also look at food patterns across different age groups.

Clinical Nutrition

Clinical nutrition classes focus on nutrients and food as they relate to disease and disease management. Students learn the language and terminology needed to work in the clinical nutrition environment. Students develop nutrition assessment, food counseling, and medical nutrition therapy skills through case studies and class exercises.

Nutrition and Exercise

Nutrition and exercise classes look at the relationship between nutrients and physical exertion. Students study how physical activity and nutrition interact at different levels of exercise, from the ordinary public to the professional athletic community. Nutrition and exercise courses also investigate how to improve overall physical health with food and diet.

Nutrition and Culture

Nutrition and culture coursework focuses on how food plays a role in human daily life. Students study the ethnic histories of food and cooking and the geography of food. They also develop skills for meal planning, food selection, food preparation, and food safety in a professional setting.

How Long Does It Take to Get a Bachelor's in Nutritional Sciences?

Degrees in nutrition science require between 120 and 130 credit hours. In addition to degree-specific classes, students complete a full range of general education coursework. Programs also provide opportunities for nutrition majors to take elective classes and focus on subject areas including fitness, finance, or sports studies.

Full-time students typically finish their bachelor's degrees in four years. Transfer students with prior college credit might complete their degrees more quickly, especially if they receive credits for general education coursework. Part-time students usually take longer to graduate.

How Much Is a Bachelor's in Nutritional Sciences?

Nutritional sciences bachelor's programs can cost between $40,000 and $60,000 per year for full-time students. Tuition per credit hour ranges from $350 to $850 for nutrition science programs, but this varies for in-state, out-of-state, and online students.

On-campus programs benefit in-state, full-time students, who often pay a flat tuition rate per semester. Part-time students usually pay per-credit tuition, instead, and often pay much more in tuition than full-time students do. Moreover, out-of-state students at public universities must usually pay higher tuition rates than in-state residents. On the other hand, some online schools charge the same tuition rates for in-state and out-of-state students, making online degrees more affordable for out-of-state students.

On-campus students often pay additional expenses that online students do not, including residence and facility fees, commuting costs, meal plans, and parking. Online students might be subject to technology and distance-learning charges, as well. Tuition, fees, and other expenses may offset each other depending on where you live and how many classes you can take at one time.

When you apply to a bachelor's program in nutritional sciences, you should submit your Free Application for Federal Student Aid (FAFSA). The FAFSA determines your eligibility for federal loans, scholarships, and grants. It also helps inform state governments and universities about your financial need.
