Are you passionate about food and its impact on health? Do you dream of empowering communities to make positive dietary choices? A career as a public health nutritionist could be your perfect fit!

What is a public health nutritionist?

A public health nutritionist is a food and nutrition expert who works to improve the overall health and well-being of populations. These professionals bridge the gap between science and practice as they translate complex nutritional information into actionable strategies for a wide range of groups and communities.  

Public health nutritionists and nutritionists differ in the ways they help people lead healthier lives through better nutrition. “Public health nutrition focuses on the health of populations and communities rather than on the health of individuals.

There is less direct service to individuals in public health nutrition than there is in other aspects of nutrition services,” says Jamie Stang, PhD, MPH, RDN, immediate Past President of the Association of State Public Health Nutritionists (ASPHN) and Professor and Chair of the Public Health Nutrition Program at the University of Minnesota, School of Public Health.

Public health nutritionists work to prevent nutrition-based problems from happening or recurring. With consideration for food equity, quality and accessibility, they apply foundational principles of nutrition to the ever-changing needs and dynamics of groups and communities. “People in public health nutrition work through policy, systems and environmental change strategies to create environments where people can make healthy choices, such as those prescribed by physicians or suggested by registered dietitians/nutritionists (RDNs),” says Stang.

A public health nutritionist can influence plans and policies to affect long-term and far-reaching change.

Why public health nutrition?

Public health nutritionists play a crucial role in promoting healthy eating habits, preventing chronic diseases like obesity and diabetes, and ensuring access to nutritious food for all. Working in public health nutrition is a chance to contribute to the creation, implementation and maintenance of public health policies and programs that achieve these goals.

“The process of changing food systems and environments can be a slow process but it affects huge numbers of people, so it makes a very big impact on the health of our communities and our country. Another rewarding aspect is being able to work across disciplines on a regular basis. Public health nutritionists work with urban planners, city council members, state and federal legislators, health program administrators, local and national nonprofits and social service providers on a regular basis,” says Stang.

A public health nutritionist can influence plans and policies to affect long-term and far-reaching change. As advocates for better nutrition, public health nutritionists can ultimately contribute to the correction of societal problems such as food insecurity and preventable chronic diseases.  


What does a public health nutritionist do?

The specific responsibilities of a public health nutritionist vary based on your position and employer but are likely to differ from those of a general nutritionist. While a nutritionist deals with individuals on a one-on-one basis, a public health nutritionist addresses nutrition based on the needs of a specific group. Depending on your role, these groups can be confined and specific like schools and hospitals or broad and heterogeneous like a city or region.

Succeeding as a public health nutritionist often requires a combination of office-based and onsite duties. Before making recommendations, a public health nutritionist must work to understand the needs, resources and challenges unique to a specific group. Achieving that knowledge often requires observation and interaction with group members, leaders and others who provide different types of support and services for the targeted group.

Typical daily tasks 

Working as a public health nutritionist offers a career in which every day can be slightly different. One day, you may be presenting a class at a hospital to educate people with diabetes on the role of nutrition in disease management. The next day, you may be meeting with a local or state legislator to discuss how budget cuts can impact people who rely on social services for healthy nutrition.

A public health nutritionist may be responsible for the following daily tasks:

  • Conduct nutritional assessments to evaluate individual and community needs.
  • Develop and deliver culturally sensitive nutrition education programs.
  • Create and promote healthy meal plans and recipes tailored to diverse populations.
  • Advocate for food policies that promote access to affordable, nutritious food.
  • Collaborate with healthcare professionals, community organizations and policymakers to address food insecurity and public health concerns.
  • Analyze data and research to monitor and evaluate the effectiveness of nutrition interventions.
  • Recommend and provide specific training in workshops, seminars, classes and programs to meet identified nutrition needs.
  • Identify or assist in the development of accurate, up-to-date nutrition education materials.
  • Participate in evidence-based nutrition research, demonstration and evaluation projects for targeted groups.
  • Remain updated about new scientific information about diet and health and make it available to those who can benefit from it.

Diverse roles and settings 

Public health nutritionists are employed in a variety of exciting settings in public, business, and non-profit sectors. You may find employment as a public health nutritionist in the following work environments:

  • Public health departments
  • Local, state and federal government programs and agencies focused on nutrition and agriculture
  • Non-profit organizations
  • Hospitals and clinics
  • Nursing homes
  • Outpatient facilities
  • Schools and universities
  • Corporate wellness programs
  • Charitable foundations
  • Food banks and community kitchens
  • Hunger relief agencies

Your education, experience and interests can impact your options for employment as a public health nutritionist. “Public health nutritionists with an MPH [Master of Public Health] degree often work in non-nutrition related programs because the MPH skills are so broad that you can work in many different areas of public health such as epidemiological surveillance, non-nutrition program administration and general health promotion or health education programs. Some work at the federal level as program analysts,” says Stang.


Skills needed to become a public health nutritionist

Public health nutritionists need advanced knowledge and experience in the principles and practices of nutrition and public health. They also need the competencies necessary to apply their expertise in the assessment, planning, organization, management, direction, coordination and evaluation of the nutritional needs of the groups they serve. Depending on your role and work environment, you may use some of these skills more often than others.

“In addition to knowing about nutrient needs, metabolism, dietary assessment methods and nutrient content of foods and beverages, public health nutrition requires that professionals understand policies such as food ordinances, land use/zoning/transportation policy and federal food assistance program regulations. Most of the work is done within community coalitions and state or local government committees, or through program planning and evaluation activities. Some public health nutritionists work primarily at the federal level, evaluating and developing policies related to federal food and nutrition standards, regulations and legislation,” says Stang.

To succeed as a public health nutritionist, it is helpful to have a combination of the following hard and soft skills:

Hard skills


Hard skills are the practical abilities, capabilities and skill sets related to the technical knowledge and training you need to work as a public health nutritionist. They include:

  • Strong foundation in food science, nutrition and public health principles
  • Ability to assess dietary intake and interpret nutritional data
  • Excellent communication and interpersonal skills to effectively educate and motivate individuals and communities
  • Public speaking skills
  • Proficiency in research methods and data analysis
  • Strong understanding of cultural competency in relation to food and dietary practices
  • Grant writing skills
  • Knowledge of policies and regulations related to food ordinances, land use and federal food assistance programs

Soft skills


Soft skills include interpersonal and personality skills that affect the ways you work and interact with other people in your role as a public health nutritionist. They include:

  • Strong leadership and collaboration skills
  • Ability to work independently and as part of a team
  • Excellent written and verbal communication skills.

“Marketing, plain language communication, social media and brief technical writing are critical skills for public health nutritionists to have.  Finally, public health nutritionists must stay abreast of the continually changing regulations related to nutrition and food policies at the federal, state and local levels,” says Stang.


5 steps to become a public health nutritionist

Becoming a public health nutritionist can be a rewarding career pathway with diverse opportunities. “Public health nutrition is an extremely dynamic field that can lead to future positions that may not even exist right now. The skill set makes you highly marketable in areas outside of nutrition, too which is nice for people who have a variety of interests,” says Stang.

  1. Research your state’s licensure requirements.

    Licensure requirements for public health nutritionists vary by state. Some states have no regulations regarding the profession. Research the licensing laws in your state to find out the type and level of education you need to work as a public health nutritionist there. In some cases, requirements may differ based on the type of position or work environment you seek. Knowing this information can help you select the appropriate educational pathway to reach your goals.

  2. Earn your bachelor’s degree.

    A bachelor’s degree in nutrition, public health nutrition, dietetics or a closely related field is the minimum educational requirement to become a public health nutritionist. Look for programs that include work experiences such as internships that can help you apply what you learn and consider your career options.

  3. Consider earning a master’s degree.

    Many public health nutritionists have a master’s degree in public health. This may be a requirement for jobs in certain work environments. Some states require it for licensure. A master’s degree, along with appropriate work experience, is also necessary to qualify for some professional certifications.

  4. Pass a licensing and or certification exam if required.

    If your state has licensure requirements for public health nutritionists, you must earn your license before pursuing employment. Research the process and apply for your license as soon as possible to avoid delays or gaps in employment. Pursue professional certifications, such as a Certification in Public Health (CPH) that can help you qualify for the positions you desire.

  5. Keep up with continuing education.

    Continuing education may be a requirement for renewal of licensure or professional certification. Even if you don’t need it for these credentials, continuing education is a good way to keep up with new research, policy changes and advancements in the practice of public health nutrition.


Education and certifications

Minimum requirements

The minimum educational requirement to become a public health nutritionist is a bachelor’s degree in nutrition, public health nutrition, dietetics or a closely related field. However, this educational requirement can vary based on the type of role you seek, employment criteria and the requirements for state licensure if you need a license in your state.

Stang advises that students look for an educational program that provides a focus on population health strategies and requires experiential learning in a public health agency. “Public health nutrition requires that people understand not just the nutrition aspects of health but also the social and economic factors such environmental health, health behavior change and intervention strategies, program planning and evaluation, policy development and evaluation, community assessment and basic epidemiology. Community nutrition or public health programs will provide these skills.”

Courses related to public health nutrition can vary based on the specific degree you pursue. Many programs require a practice experience or internship. These experiences are valuable opportunities to test the waters in the field of public nutrition and refine your interests and career goals.

Some degrees require a capstone project. This involves research and writing projects that demonstrate the skills and knowledge you learned during your studies. At the graduate level, a research-based master’s thesis may be required.

The types of subjects you will study in these degrees include:

  • Introduction to Psychology
  • Introduction to Modern Chemistry
  • Principles of Organic and Biological Chemistry
  • Introduction to Human Physiology
  • Introduction to Foods and Food Science
  • Food Production and Management
  • Foundations of Public Health
  • U.S. Food Systems Policy
  • Theories and Techniques of Nutrition Education and Counseling
  • Global Issues in Social and Behavioral Health
  • Cultural and Community Nutrition

“Many public health nutritionists have a degree in nutrition with a master’s degree in public health. Some have a degree in nutrition with extensive experience working in nonprofits or on local/state legislative or policy committees,” says Stang.

Accreditation

When choosing an educational program, verify that you will be attending an accredited institution and program. An accredited school has met industry standards for quality of education, criteria that are necessary if you wish to apply for federal financial aid, state licensure and/or certain certifications. In addition, credits from an accredited school can often be transferred to another school or used to meet requirements for a higher-level degree.

You can check school accreditation on the U.S. Department of Education’s Database of Accredited Postsecondary Institutions and Programs or the Council for Higher Education Accreditation (CHEA) Database.


Licensure or certification

In some states, becoming a licensed Registered Dietitian (RD) may be necessary for certain practice settings. It’s important to understand the requirements for licensure and/or certification of public health nutritionists in your state. Without the proper credentials, you may not qualify for the types of jobs you desire. Here are how these credentials differ:

A license is a credential legally required by the government to work in a specific occupation. Earning a license typically requires meeting predetermined criteria such as having a specific degree and/or passing a state-administered exam and passing state-issued criteria.

Certification is a professional credential that proves you have mastered the knowledge and skills necessary to work in a specific role. It is awarded by a professional organization to candidates who meet specified criteria for education, experience and examination.

Certification differs from a certificate. A certificate is awarded by an educational institution as proof that a student has satisfactorily completed a given curriculum. Certificate programs can help students prepare for licensure or certification exams.

Rules for licensure of public health nutritionists vary widely across U.S. states. While most U.S. states regulate registered dietitians, more than half have no educational or experience requirements for nutritionists. Some states require licensing or certification for nutritionists specifically, others award a dual dietitian/nutritionist credential that allows you to use either title in those states.

Check on your state licensure requirements by using this handy tool. Follow up with your state licensure board to confirm the requirements to ensure your chosen educational pathway will provide the requirements you need to qualify for licensure in your state.

Certifications

Professional certification proves that you have mastered the knowledge and skills necessary to work in a specific role. Requirements for specific certifications can vary based on requirements by state licensure boards and/or employers.

“Many public health nutritionists are registered dietitians (have taken the Commission on Dietetic Registration examination), but that credential is not always required. There is a Certification in Public Health (CPH) credential that is required by some health departments or grant funding sources. Eligibility for this credential is through an MPH degree and examination,” says Stang.

The benefits of professional certification can include improved opportunities for employment and advancement. It may also qualify you for higher salaries. Professional certification can also help you convey your commitment to professional development and lifelong learning in your profession.

The most common professional certifications for public health nutritionists include:

Certification: Registered Dietitian (RD)
Certifying Body: Commission on Dietetic Registration
Recertification: Every five years with continuing education requirement and fee

Certification: Registered Dietitian/Nutritionist (RDN)
Certifying Body: Commission on Dietetic Registration
Recertification: Every five years with continuing education requirement and fee

Certification: Certification in Public Health (CPH)
Certifying Body: National Board of Public Health Examiners (NBPHE) 
Recertification: Every two years with continuing education requirement and fee

Continuing education

Ongoing professional development and staying current with the latest research in nutrition is essential to succeed as a public health nutritionist. Continuing education helps you accomplish this goal in the form of seminars, conferences, courses, research and other types of professional development and career enhancement. It may also be required to prove your dedication to remaining current as a condition of licensure or professional certification renewal.

Whether by requirement or choice, pursuing continuing education in public health nutrition can help you remain current with best practices and emerging research. It can also provide opportunities to explore new interests and advance existing expertise as you expand your knowledge and skills.
