Once a year, a special day is dedicated to registered dietitian nutritionists. The Academy of Nutrition and Dietetics (1) celebrates Registered Dietitian Nutritionist Day each year on the second Wednesday in March. This year it falls on March 13th. While we need to celebrate what a registered dietitian does every day, this commemoration is a welcome step. First celebrated in 2008, it was created to increase the awareness of registered dietitian nutritionists as indispensable providers of timely, scientifically validated food & nutrition information and services.
Pretty cool, right?! A whole day dedicated just to registered dietitian nutritionists! But you might be wondering, what is a registered dietitian? What do they do? Why should you see one? And what can they help you with?

What is a Registered Dietitian?
A registered dietitian is a nutrition professional who has been trained to meet the strict educational and experiential standards set by the Commission on Dietetic Registration (CDR) of the Academy of Nutrition and Dietetics.
In forty-seven states, Puerto Rico and the District of Columbia, dietitians are the only nutrition professionals to be regulated by licensing laws. It is these laws that help the public identify and access qualified practitioners. Licensing laws also provide health insurance companies and state & federal governments with the assurance that these practitioners meet standards of professional competence in order to be reimbursed for providing nutrition care services.
You may find dietitians in a variety of settings, including (but not limited to) hospitals, long term care facilities, schools, community health facilities, corporate nutrition programs, the food and nutrition industry, business, sports nutrition and research.
What does a Registered Dietitian do?
Registered dietitians are health professionals qualified to assess, diagnose and treat nutritional concerns at an individual and wider public health level. This means they are the ones you can head to when you are in need of nutritional expertise that is scientifically proven to help you reach your wellness goals.
A dietitian’s job description and what they do varies depending on the setting in which they work. In general, dietitians advise and counsel others on food and nutrition. Typically, they may assess the dietary and health needs of clients, explain nutrition issues to clients, develop meal plans and gauge the effectiveness of these meal plans, promote nutrition through public speaking and community outreach, and keep up to date with the latest food and nutrition research.
Since they cover such a wide range of nutrition-based subjects, in practice, you find dietitians working in various settings with a wide range of roles:
In hospitals
- Assess and plan nutrition care for patients with a variety of ailments

Why should I see a Registered Dietitian?
Michael Phelps already knows how to swim. George Clooney already knows how to act. Tom Brady already knows how to play football. Do you think they still hire coaches? Of course, they do! The tricky bit with nutrition is that we all eat…often several times a day, so we are all “experienced” at eating, and automatically have strong opinions on eating. Most of us also have a lot of experience driving cars, sometimes multiple times per day, yet we’re not as eager to hand out advice on cars.
The point here is that experience does not necessarily mean expertise. Registered Dietitians have that expertise! They have completed a university degree in foods and nutrition from an accredited institution, and they have worked 900+ hours in supervised practical training. They have passed an exam to become a registered health professional and are required to complete ongoing professional development. They are also held to a rigorous professional code of ethics! If that doesn’t scream expertise in the realm of food and nutrition, what does?

What can a Registered Dietitian help me with?
Dietitians are valuable members of your health care team and can be there to support you throughout your life. Here are just a few things that a dietitian can help you with:

What questions should you ask a Registered Dietitian?
Finding a great dietitian can feel like a big task. Here are some questions to ask that can help you in the process.
- What’s your specialty and approach? Once you find a dietitian, you want to make sure that their specialties and philosophies jive with yours. Some dietitians have additional certifications in nutrition for diabetes (CNE) or are board-certified sports dietitians (CSSD). Some will write meal plans for you, while others focus on behavioral strategies rather than calorie counting.
- How much do sessions cost – and do you take insurance? Costs will vary by location, the dietitian’s experience, and their specialty. How often and how long you work with your dietitian is up to the two of you. Another factor that can make a difference in your bottom line is whether or not the dietitian accepts insurance.
- Do you offer any group programs? Some dietitians offer both in-person sessions as well as online support groups. While they may not be right for everyone, groups can be especially helpful for people who find strength in numbers. It can help to have support from people who are experiencing similar things.
Remember, at the end of the day, the most important thing is that you are comfortable with the person you are working with. Your health is a priority, so it’s important to find someone you trust to help guide you on your journey.
