What is a Nutritionist?

A nutritionist is not a dietitian. Today’s terminology may be a bit confusing, but Registered Dietitian Nutritionists (RDNs), which are credentialed by the Academy of Nutrition and Dietetics, are not nutritionists. All dietitians are nutritionists, but all nutritionists are not dietitians. This article will further elaborate upon what makes a nutritionist a nutritionist.

Nutritionist Job Description

Nutritionists may be certified by the Board for Certification of Nutrition Specialists or the Clinical Nutrition Certification Board. Training requirements for nutritionists vary from one state to the next, and most states do not require nutritionists to be licensed nor certified. A nutritionist generally provides advice to clients on how to:

• Eat healthily
• Lose weight
• Reduce fatigue and tiredness through changing what they eat

Job Duties of a Nutritionist

Nutritionists may treat a variety of health conditions, depending upon the laws of their state. Because nutritionists need not have certification or licensure, some states will not allow them to perform nutritional counseling or to diagnose and treat certain health conditions. Other states will allow nutritionists to perform nutrition counseling, but will not allow them to bill health insurance for their services.

States that do require certifications or licensure for nutritionists include: Maryland, Illinois, Ohio, Georgia, Alabama, Mississippi, Tennessee, Missouri, Iowa, Kansas, Nebraska, South Dakota, North Dakota, Montana, Wyoming.

If a Certified Nutrition Specialist (CNS) (certified by the Board for Certification for Nutrition Specialists) has state licensure, they are legally authorized to treat any health conditions an RD can treat. Some of their duties include:

• Providing nutrition therapy to manage illnesses/health conditions
• Overseeing community education programs
