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.

The Associate of Science degree in nutrition gives students a basic overview of the discipline, as well as hands-on training that prepares them to work in the field. Although students cannot become licensed nutritionists by earning this degree alone, they can obtain employment as dietetic technicians, working under the supervision of a registered nutritionist or dietitian. In addition, this degree lays the foundation for students who eventually decide to continue their education with an eye toward becoming licensed.
Students in this program complete a well-rounded curriculum, including general studies courses in topics such as mathematics, writing and public speaking. Core nutrition courses in this program include weight management theory, herbal sciences, community nutrition, sports nutrition, sustainable food systems and cultural foods.
These degrees typically take two years to complete, and depending on the program, students may be able to receive on-the-job training through an internship. Following are examples of courses offered at this level:

By the time they graduate, they will be able to design studies and carry out evidence-based research, as well as present their findings to the scientific community. 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.
