Navigating the Noise: Who Can You *Really* Trust for Nutrition Advice?
We’re bombarded with dietary advice. From Instagram influencers to TikTok trends, everyone seems to have an opinion on what you should eat. But with so much information, how do you determine who’s qualified to guide you toward healthier habits, weight management, or managing a health condition through diet? The answer isn’t always who has the biggest following.
What Does it Mean to be a Registered Dietitian-Nutritionist (RDN)?
Registered Dietitian-Nutritionist (RDN) is a protected professional credential. To earn the RDN title, an individual needs a bachelor’s degree and must complete coursework accredited by the Accreditation Council for Education in Nutrition and Dietetics. This represents followed by a 6-to-12-month accredited supervised practice program and passing a national exam administered by the Commission on Dietetic Registration, according to the Academy of Nutrition and Dietetics. Maintaining this credential requires ongoing continuing education.
RDN vs. Registered Dietitian: Is There a Difference?
No. According to Jennifer Bruning, RDN, a spokesperson for the Academy of Nutrition and Dietetics, the terms RDN and Registered Dietitian (RD) are interchangeable.
Nutritionist: A Term Without Boundaries
Unlike RDN, anyone can call themselves a “nutritionist.” It’s an unregulated term. The “N” was added to the RDN credential to clarify this distinction – all dietitians are nutritionists, but not all nutritionists are dietitians.
State Credentialing: Adding Another Layer
You may encounter additional letters after an RD or RDN’s name, such as LD (Licensed Dietitian), LDN (Licensed Dietitian-Nutritionist), or CDN (Certified Dietitian-Nutritionist). These are state-level licenses, varying by location. While RDN/RD is a national registration, state credentials confirm the practitioner is licensed to practice within that specific state.
What Can a Registered Dietitian-Nutritionist Actually Do For You?
RDNs are uniquely qualified to provide expert advice on a wide range of nutrition and health topics. They are the only accredited healthcare providers who can offer medical nutrition therapy. They can help with:
- Understanding the basics of healthy eating
- Developing plans for weight gain or loss
- Managing chronic diseases like heart disease, diabetes, or cancer
- Navigating food allergies or intolerances
- Recovering from eating disorders
Health Coaches: Where Do They Fit In?
Certified health coaches focus on behavioral changes to help you reach your health goals. They “partner with clients seeking to enhance their well-being through self-directed, lasting changes, aligned with their values,” according to the National Board for Health and Wellness Coaching. Some health coaches are similarly RDNs, holding a Certificate of Training from the Academy of Nutrition and Dietetics. The type of accreditation a health coach has determines the scope of diet and nutrition advice they can provide.
Specialized Dietary Approaches: What About Sports Nutrition, Culinary, or Holistic Medicine?
The Commission on Dietetic Registration offers seven specialty board certifications, identified by a “CS” prefix. These include certifications in gerontological, oncology, pediatric, renal, sports dietetics, and obesity and weight management (e.g., CSSD for sports dietetics, CSOWM for obesity and weight management). For other specialized areas like culinary nutrition or functional medicine, there isn’t a standardized credential, but RDNs often pursue additional training in these areas.

Popular Diets: Keto, Intermittent Fasting, and More
RDNs stay current on diet trends, including keto and intermittent fasting, to provide informed guidance on safety and nutritional considerations. They can help individuals explore these approaches healthfully.
Nutrition Credentials for Specific Health Concerns
If you have a medical condition, a properly trained and credentialed nutrition practitioner is essential. Here’s what to look for:
- Diabetes: Certified Diabetes Care and Education Specialist (CDCES)
- Chronic Kidney Disease: Board Certified Specialist in Renal Nutrition (CSR)
- Cancer: Board Certified Specialist in Oncology Nutrition (CSO)
- Heart Disease/High Blood Pressure: Dietitian specializing in CV-WELL (cardiovascular health and well-being)
- Pregnancy: RDN who is also a Certified Lactation Counselor (CLC)
- Eating Disorder: RDN who is a Certified Eating Disorders Specialist (CEDS)
Pro Tip
Don’t hesitate to inquire any nutrition professional about their education, training, and experience. A qualified professional will be happy to share this information and refer you to someone else if they aren’t the best fit for your needs.
