Current situation in Hong Kong
There is no statutory registration or licensing board for dietitians and nutritionists in Hong Kong.
Since the titles of dietitian and nutritionist are not protected in Hong Kong, it is not against the law that someone, without relevant academic background, to call himself or herself to practise as a dietitian or a nutritionist in the community.
However, the Department of Health of the HKSAR Government and the Hospital Authority, the two major dietitian employers in Hong Kong, only recognize holders of the Postgraduate Diploma or MSc in Human Nutrition and Dietetics of Hong Kong University SPACE, or its equivalent qualifications, namely, Registered Dietitian on Commission of Dietetic Registration, Academy of Nutrition and Dietetics (USA); or Registered Dietitian of Health and Care Professions Council (UK); or Registered Dietitian of Provincial Registration, Dietitians of Canada; or Accredited Practising Dietitians of Dietitians Association of Australia.
Neither the Department of Health nor Hospital Authority has post for a nutritionist.
To help the public to identify qualified dietitians, HKDA full members are given the title "Accredited Dietitian". To maintain the Accredited/Full Membership status, a HKDA full member has to fulfill the requirements for continuing dietetic education program.
