Wahoo! Go hug or say thanks to an RDN you know today! Set up an appointment to work on a nutrition goal and you’ll really make their day!

Have you ever wondered what the difference is between a dietitian and a nutritionist? Most people think they’re one and the same and then wonder why dietitians tend to be picky about what they’re called. Seems silly, I know, but here’s why …

To become a registered dietitian nutritionist you have to go to an accredited four year bachelor of science program and get a degree in dietetics. The classes are very science heavy (I was one class away from a Chemistry minor). After graduation, we have to complete an approved dietetic internship for 9-24 months that can be compared to a medical residency. We follow registered dietitians and gain experience, all while paying for the experience and likely not having time to hold a job. Then we have to take a very difficult national exam to finally earn the RDN (Registered Dietitian Nutritionist) after our name. It’s a lot of work! On top of that, many dietitians go on to get a Masters degree. I chose to get one and I’m so happy I did! Oh, but it doesn’t end there. We are required to take continuing education hours and pay fees to keep our credentials up to date. The point is, it’s a lot of time, effort, and sacrifice to become an RDN! But it is SO worth it to have the background I need to truly help my patients and clients. Nutrition is a very complex field and I’m grateful that I have the education to help me analyze all the varying research out there to help my patients make the most progress possible and create a nutrition plan that is individualized to their particular body, genetics, lifestyle, strengths and weaknesses. RDNs truly are the nutrition experts.

On the other hand, to become a nutritionist you need no special education, tests, or credentialing. In most states, nothing is required, meaning absolutely anyone can call themselves a “nutritionist!” Scary, isn’t it? To sum up, all registered dietitians are nutritionists, but not all nutritionists are registered dietitians. Kind of like all apples are fruit, but not all fruits are apples. See!

So, anytime you have a nutrition question or need some nutritional guidance, please go to the experts in nutrition and see your local, friendly RDN! You can find an RDN near you here: Find an Expert
