To eat or not to eat?

Are you interested in eating healthy, keeping fit, and staying well? Whether you have a specific objective like losing weight, reducing high cholesterol, or you're looking for overall ways to stay fit and healthy, a Registered Dietitian can help you find your way through health and nutrition claims and design a personalized nutrition program.

Registered Dietitian vs. Nutritionist

Registered dietitian

Dietitians are experts in food and nutrition that must have at least a bachelors degree, while some have a masters degree. Dietitians give dietary advice, help promote healthy eating habits, develop specific diets for people, and participate in nutrition research. They are regulated by the Academy of Nutrition and Dietetics (AND). They must meet strict educational and professional prerequisites and pass a national exam before functioning as a Registered Dietitian. Every dietitian is a nutritionist, but not every nutritionist is a dietitian.


Nutritionists are health specialists who are interested in food and nutritional science, preventative nutrition, diseases related to nutrient deficiencies and the use of food and nutrients to cure disease and ailments. Nutritionist are not regulated. They have varying degrees of education in nutrition - some have very little and some may have a masters or PhD. Since the term "nutritionist" isn't regulated, anyone can call themselves a nutritionist and dispense nutritional information without having any education whatsoever.
