What Does a Dietitian Do


Registered dietitians are health care professionals who are trained to provide advice and counselling about diet, food and nutrition. They use the best available evidence coupled with good judgment about the client’s or communities’ unique values and circumstances to determine guidance and recommendations.

Dietitians help people make healthy food choices, separating fact from fiction and distinguishing healthy eating plans from those that don’t provide optimal nourishment. Dietitians play a major role in health care, industry, government and education. They influence policy development, direct nutrition programs, manage quality food services and conduct nutrition research.

Dietitians are regulated health professionals. To use the title Registered Dietitian (RD), dietitians must be registered with the dietetic regulatory body in the province in which they practice.
