People often use the titles “dietitian” and “nutritionist” interchangeably.
In fact, in the last 10+ years that I have worked in the field of dietetics, I have been called a dietitian, dietician, nutritionist, nutritionalist (this is not even a word)… and even doctor (which I am not). Dietitians and nutritionists both help people make healthier food choices to improve their health but their qualifications and credentials vary greatly.
Simply stated, “all dietitians are nutritionists but not all nutritionists are dietitians”. What does that mean?
- A Registered Dietitian or Registered Dietitian Nutritionist are licensed and credentialed professionals who treat and manage medical conditions such as obesity, heart disease, diabetes, cancer, etc.
- Nutritionists are not always certified and regulations can vary from state to state Nutritionists may include anyone who calls themselves a nutritionist with no formal training to those who obtain advanced degrees. Those with advanced degrees may obtain a Certified Nutrition Specialist (CNS) or Integrative Functional Nutrition Certified Practitioner (IFNCP) credential.
