The main difference between a Registered Dietitian and a Nutritionist is that RDs have standardized credentials, including a degree, supervised practice, and passing a national exam, making them qualified for clinical and healthcare roles. Nutritionists may have similar knowledge but lack standardized certification, which can affect their scope of practice and recognition in healthcare settings.
