The foundational courses help students understand how the body works and processes food at biological and chemical levels.

Nutrition programs may have concentrations in nutrition science or dietetics. Alternatively, they may be under the title of health sciences degrees with a nutrition or health and wellness specialization. Some programs may include research into diseases, environmental effects on food, and utilizing technology for treating patients. A bachelor's degree in nutrition is the minimum requirement to begin a career as a nutrition consultant, nutrition educator, or dietitian. Earning this degree helps prepare students for pursuing an advanced nutrition program in graduate school or a master's degree in related fields, such as nursing and biology.

Admission Requirements

Admission requirements depend on the school, but in general, applicants need a high school diploma or GED. They will need to submit these transcripts alongside their SAT or ACT scores. Some schools also require particular prerequisite courses and/or minimum GPAs.


Accreditation is a term used to describe the process by which schools are evaluated for their quality and their ability to provide students with a valuable education. Independent regional and national agencies evaluate institutions of higher education based on a variety of factors and determine whether to grant them accreditation. Legitimate accrediting agencies should always be recognized by the U.S. Department of Education or the Council for Higher Education Accreditation.

Accreditation helps ensure that online students receive a high quality education and meet eligibility requirements for federal financial aid. In addition, for students who decide to transfer credits to another school or pursue an advanced degree, it will be important to have attended an accredited school or program.

What Is ACEND Accreditation?

Many schools seek accreditation from professional organizations for individual programs within the school. For nutrition degree programs, the preferred programmatic accreditation comes from the Accreditation Council for Education in Nutrition and Dietetics (ACEND). Accreditation by this industry-recognized agency helps ensure that a program meets national standards of excellence and prepares students for many industry certifications.

Most schools indicate whether the nutrition program is ACEND-accredited on their website, or prospective students can check the ACEND directory.

Online Nutrition Classes

Students enrolled in online nutrition bachelor's programs typically complete a mix of science-based courses that aim to cover nutrition's effect on the human body, skills courses that help prepare students to assess and guide patients, and management courses that generally cover how to lead food service operations. Programs may also require an internship and are usually designed to prepare graduates for the Registered Dietitian exam.

The following are some examples of classes typically found in an online nutrition degree program.

Anatomy and Physiology

This course aims to cover the essential terms and concepts describing the human body's structure and function. Students may also gain an understanding of various diseases, organ systems, digestion, metabolism, and changing nutritional needs throughout the typical human life cycle. With some online programs, this course may include applications-oriented lab work, which may be conducted at home or virtually.

Food Service Management

This business management course is designed to provide students with the administrative knowledge and professional skills needed to lead a food service operation. Key topics in the course typically include organizational structure, food preparation, institutional equipment, menu planning, budgeting, marketing, and human resource management. Professional ethics in management is woven throughout the course's content.

Medical Assessment

Students in this course focus on learning practical skills related to assessing patients from the perspective of a nutrition consultant. Specific health indicators explained in the course generally include blood pressure, height and weight, body mass index, and body composition analysis. Additional coursework may include developing recommendations and plans for patients.


Typically requiring lab work, students in a microbiology course study nutrition at the cellular level. Students learn the basic types of microorganisms — viruses, bacteria, algae, fungi, and protozoa — and discover how they affect health, ecology, and related fields. To complete the hands-on lab requirements, online students may be asked to conduct experiments virtually or at home, using common household items or kits delivered by the school.

Nutrition Science

This introductory science course focuses on the relationship between nutrients and the human body. Students may learn about internal food systems and how the body processes food on a chemical level. Additional topics covered in the course may include allergies and intolerances, healthy dietary habits and patterns, energy balance, and the availability and presentation of nutrition information.

Optimal Health and Performance

A companion to the medical assessment course, this class typically covers how to work with patients to help them adopt useful dietary changes into their lifestyles and enhance their health through physical activity. Students study to gain practical knowledge regarding concepts, attitudes, and strategies for effectively coaching patients.

Resource Production and Allocation

Nutritionists should have a basic understanding of economics as it relates to the food industry. Topics in this course often include agricultural production, food safety, government regulation, property rights, and natural resources.

Nutrition Degree Concentrations

Concentrations help students customize their degrees to specialize in an area of interest. Specialization may be helpful in careers that require specific expertise, such as working with particular populations in unique environments.

There are several concentrations to choose from when pursuing an online nutrition degree program:

  • Dietetics takes a science-heavy approach to nutrition that involves studying medical nutrition therapy and diagnosing eating disorders.
  • Food Safety and Nutrition focuses on healthy eating habits and food safety and how both can impact health.
  • Food Service Administration concentrates on providing food and nutrition in institutional environments, such as schools, hospitals, and prisons.
  • Nutrition and Fitness explores the mind-body connection and the interplay between body mechanics, physiology, and food.
  • Public Health Nutrition integrates nutrition with public health principles into the design of programs focused on maintaining or improving the health of communities and targeted populations.

Certification and Licensing Requirements for Nutritionists

After completing a nutrition or dietitian degree, many graduates choose to become certified or registered as a nutritionist or dietitian. Some states allow graduates to practice as nutritionists without licensure, but because the requirements vary from state to state, aspiring nutritionists and dietitians should verify their state's regulations before taking any major steps. The following is a general overview of some commonly accepted certifications in the nutrition profession.

Differences in Educational Requirements: CCN, CNS, and RD

Individuals hoping to earn CCN, CNS, and Registered Dietician (RD) credentials must meet different educational requirements before they take the certification exams.

The CCN is open to individuals with a range of academic backgrounds, from individuals with associate degrees in nursing to medical and naturopathic doctors. However, to take the CCN exam, individuals who don't have a graduate degree must show they have fulfilled all CNCB academic requirements and take the PGSCN intensive course offered by CNCB. To earn the CNS, individuals must hold a qualifying graduate or medical degree. CNS applicants don't need to take a pre-qualifier intensive course before they register for the CNS exam. An RD is a food and dietary professional with a bachelor's degree in nutrition or a qualifying field. RDs also complete a 900-1,200 hour internship and pass a dietetics registration exam.

What Can You Do with an Online Bachelor's Degree in Nutrition

Graduates of online nutrition degree programs have the opportunity to enter a variety of professional roles, depending on their experience.

Is an Online Nutrition Degree Worth It?

Nutrition may be a worthwhile degree if you have a desire to use your knowledge to help others and you're interested in science, anatomy, health, and food. Earning a degree in this field could yield a high return on your investment. However, enrolling in school takes time and money that may put a strain on your personal life and budget. When determining a nutrition degree's worth, it may be helpful to not only consider your unique circumstances — such as your finances, professional goals, and the time you're willing to commit — but also some of the following advantages and disadvantages.

Potential Benefits:

Nutrition is a diverse field that could lead to several career options. Students can use the skills gained through an online bachelor's degree in nutrition for many occupations that aim to keep people healthy.

The demand for skilled nutritionists is expected to grow over the next decade. More and more people need trained professionals to help them manage their health through dietary choices. In fact, experts project 5,900 job openings for nutritionists each year through 2030.

Potential Drawbacks:

A graduate degree may be required to achieve certain careers in the field. In order to achieve certification as a nutrition specialist or be hired by some employers, aspiring dietitians may need to pursue a master's degree, which is an additional commitment of time and money.

Becoming a nutritionist can be expensive, even beyond tuition costs. You may have to budget for other expenses, such as certification and licensure fees, exam fees, and continuing education courses. You may also have to pay for annual membership to organizations, such as the Academy of Nutrition and Dietetics, to keep abreast of the latest nutrition and science news.

Dietitians report experiencing lower-than-average job satisfaction, according to CareerExplorer. Survey respondents rate 2.9 overall job satisfaction out of 5, placing dietitians at the bottom 26% of all careers.

Is Becoming a Registered Dietitian Worth It?

Whether becoming an RD is worth it depends on your career goals. In addition to earning a bachelor's in nutrition — or a master's degree as of 2024 — you'll need to fulfill the following requirements: complete a supervised practice program, pass the Registered Examination for Dietitians, and engage in continuing education to maintain your certification.

RD certification helps prepare you to assume management positions in hospitals, government agencies, and other healthcare facilities. However, earning certification requires a significant investment of time, money, and effort in education that may not be worth the slight increase in salary compared to a nutritionist. A 2019 survey from the Academy of Nutrition and Dietetics, a secondary source from the BLS, shows that full-time RDs make approximately $68,600 per year, which is only about $5,000 more than the median salary for nutritionists. Ultimately, the choice to become an RD may depend on where you'd like to work, your job's earning potential, and your educational goals.

RD certification helps prepare you to assume management positions in hospitals, government agencies, and other healthcare facilities.

It's also important to note that some states allow you to practice as an unlicensed nutritionist, performing many of the same functions as an RD. You may want to check your state's regulations before choosing your career path so you can make an informed decision.
