Not all nutritionists are dietitians - anybody can call themselves a nutritionist in BC, Canada. The titles "Dietitian", "Registered Dietitian" and the initials "RD" are protected by law in BC.   Dietitians are regulated under the Health Professions Act, Dietitians Regulation and the CDBC Bylaws.  Under the Health Professions Act, the mandate of the College of Dietitians of BC is to protect the BC public by regulating Dietitians to practice safely, ethically and competently. Dietitians are regulated the same way "nurses", "pharmacists", "doctors" are.  Only people who are registered with the College of Dietitians of British Columbia, may use the title and practice as Dietitians in BC.
