If you’ve ever searched “nutrition help near me,” you’ve probably been overwhelmed by options — influencers, coaches, clinicians, and everything in between. It’s very common to hear the terms dietitian (or dietician) and nutritionist used interchangeably.
But there is an important difference.
The distinction comes down to training, credentials, scope of practice, and legal responsibility — especially when medical conditions are involved.
Differences in Training and Credentials
Registered Dietitian Nutritionists (RDNs) are licensed healthcare professionals who must complete rigorous training, including:
- A bachelor’s (and now often a master’s) degree in nutrition or a related field
- Supervised clinical training (a dietetic internship)
- Passing a national licensing exam
- Ongoing continuing education
Dietitians are licensed in many states, including Massachusetts, which means we’re legally held to a high standard of care. We work in hospitals, clinics, community health settings, and private practices — both in Boston and via telehealth.
And just to be clear: We do not promote or advocate for cardboard meals.
We believe food should be nourishing and enjoyable.
What About Nutritionists?
The title “nutritionist” is not regulated in many states. That means people can have widely varying backgrounds — from advanced degrees to weekend certifications (or none at all).
This doesn’t mean nutritionists are bad or unhelpful. It simply means it’s important to ask about:
- Education
- Credentials
- Scope of practice
Nutritionists cannot provide medical nutrition therapy or treat medical conditions unless they also hold licensed credentials.
Does Insurance Cover Dietitians or Nutritionists?
Insurance covers nutrition care only when provided by a licensed Registered Dietitian Nutritionist.
Thanks to the Affordable Care Act, many insurance plans now cover medical nutrition therapy for the prevention and management of chronic disease.
Insurance does not cover:
- Nutrition coaching
- Non-licensed nutritionists
At Boston Nutritionist, we are in-network with most major insurance plans. Coverage varies by plan, so we’re happy to help verify benefits and explain your options.
Should You See a Dietitian or a Nutritionist?
You should see a Registered Dietitian Nutritionist if you:
- Have (or suspect) a medical condition
- Are managing diabetes, heart disease, GI issues, autoimmune conditions, food intolerances and allergies, or eating disorders
- Need evidence-based, individualized nutrition therapy
Dietitians are trained and licensed to provide medical nutrition therapy. Nutritionists and coaches are not.
At Boston Nutritionist, all clinicians are Registered Dietitian Nutritionists. We provide inclusive, compassionate care — both in Boston and through secure online nutrition therapy across Massachusetts and beyond.
