The path to becoming a nutritionist depends on education, experience and location. Regarding the latter, many states have formal licensing and certification requirements in order to work in the field. Even in states that do not have specific requirements, employers and clients may give preference in hiring to people with these credentials.
This page is designed to help aspiring nutritionists better understand the key issues and questions that arise during the educational process, including: What’s the difference between an RDN and a CNS credential? Do I need a degree? What types of science classes will I need to take? Find answers to these questions below, as well as the primary steps people take when looking to become a nutritionist.
Nutritionists are experts in food and nutrition. They can help patients choose the right things to eat, help them plan menus, and advise them on the health effects of certain foods. Nutritionists assess a patient’s current dietary habits and needs, educate them on healthy eating habits, follow up to ensure the menus are working, and write reports that document a patient’s progress.
They might also speak to groups, such as schools or businesses, about good nutrition and preventing health problems through proper foods. Nutritionists frequently work closely with individuals who have medical issues, such as those with diabetes or those undergoing chemotherapy, to help them find the right foods to eat for their best possible health.
Nutritionists help their clients stay focused on their goals by providing regular encouragement and motivation. They discuss the pros and cons of specific diets and food trends, and what impact those have on health. Depending on education level or licensure, a nutritionist may test for specific food allergies or autoimmune disorders such as celiac disease (gluten intolerance).
Educating people on health is an important job in today’s society, especially in the United States, where obesity has reached an all-time high. Nutritionists can work as self-employed entrepreneurs, as well as in hospital settings, schools and a variety of holistic and alternative medicine environments. Depending on their level of education, nutritionists can be in high demand in food and health-related businesses.
According to the U.S. Bureau of Labor Statistics, nutritionists earned a median annual wage of $56,950 in 2014, while the top ten percent of the profession made $79,840 or more. The agency also found that on average, nutritionists earned an hourly rate of $27.38. The states with the highest average salaries for nutritionists in 2014 are as follows:
The map below shows details of the 10th, 50th, and 90th percentile earners for each state.
According to the U.S. Bureau of Labor Statistics, the job opportunities for nutritionists are expected to increase by 21 percent between 2012 and 2022. That growth, the agency reports, is much higher than the average for all occupations. This increase has been attributed to the nationwide concern about rising obesity rates and the illnesses that can be exacerbated by obesity—such as diabetes and heart disease. In addition, as people live longer, there is a need for nutritionists to work with geriatric patients in facilities such as nursing homes. Trends toward eating locally grown, organic and non-genetically modified foods have also opened up opportunities for nutritionists who specialize in those areas.

In addition, these programs give students an understanding of research ethics, an issue that is especially important when dealing with human subjects.
In order to provide care to patients, nutritionists must be able to make dietary assessments. Doctoral degree programs provide in-depth knowledge of how to assess a patient’s existing dietary behaviors and habits, as well as identify current and future needs.
Nutritionists must make informed decisions about the treatment their patients should receive. This may involve several factors, including not only their patients’ physical health but also their mental attitudes. They use their understanding of nutrients, physiology and disease to craft an appropriate diet and implement an overall nutrition plan, as well as make adjustments as a patient’s condition changes.
It’s important for nutritionists to hone their verbal and written communication skills, since they may find themselves in roles where they are called on to educate the public about the importance of good nutrition. This entails taking complicated concepts and making them understandable and relevant to the general public, using a combination of scientific information and persuasion to convince a community of the importance of eating right.
