A nutritionist is a person who advises on matters of food and nutrition impacts on health. Different professional terms are used in different countries, employment settings and contexts — some examples include: nutrition scientist, public health nutritionist, dietitian-nutritionist, clinical nutritionist, and sports nutritionist.

Some use the terms "dietitian" and "nutritionist" as basically interchangeable.[1] However in many countries and jurisdictions, the title "nutritionist" is not subject to professional regulation; any person may call themselves a nutrition expert even if they are wholly self-taught.[2] In most US states, parts of Canada, Australia, and the United Kingdom, the term nutritionist is not legally protected, whereas the title of dietitian can be used only by those who have met specified professional requirements. One career counselor attempting to describe the difference between the two professions to Canadian students suggested "all dietitians are nutritionists, but not all nutritionists are dietitians."[3]


Regulation of the title "nutritionist"


The title "nutritionist" is protected by provincial law in Quebec, Alberta, Nova Scotia and British Columbia. The term “Registered Dietitian/Nutritionist” is protected by law in New Brunswick.[4]

For example, the Nova Scotia Dietetic Association is the regulatory body for professional dietitians and nutritionists in that province, authorized by legislation, the Professional Dietitians Act, "to engage in registration, quality assurance, and when necessary, the discipline of dietitians in Nova Scotia to ensure safe, ethical and competent dietetic practice." Professional requirements include a Bachelor's Degree in Dietetics/Nutrition from an accredited university, a program of practical training, and successful completion of a registration examination (the "Canadian Dietetic Registration Examination" or CDRE).[5]

South Africa

In South Africa, nutritionists must be registered with the Health Professions Council of South Africa.[6] The Council regulates the professional titles of "Nutritionist", "Student Nutritionist", and "Supplementary Nutritionist", along with "Dietitian, "Student Dietitian", and Supplementary Dietitian". Requirements for eligibility for registration include a recognised Bachelors degree from an accredited educational institution. The undergraduate training should include the three practice areas of therapeutic nutrition, community nutrition, and food service management.

United Kingdom

Nutritionist is not a protected term in the UK, unlike dietitians, who must be registered with the Health Professions Council.[7] Different organizations use their own criteria to define a nutritionist. According to one of these, the Nutrition Society,[8] “the function of a nutritionist is to elicit, integrate, disseminate and apply scientific knowledge drawn from the relevant sciences, to promote an understanding of the effects of nutrition, and to enhance the impact of food on health and well-being of animals and/or people”.[9] They accredit nutritionists, conferring the titles Associate Nutritionist (ANutr) and Associate Public Health Nutritionist (APHNutr). For these they consider an undergraduate training [10] sufficient for associate membership. Full registration as a Registered Nutritionist (R Nutr.), or Registered Public Health Nutritionist (RPHNutr) requires at least three years work experience and the fulfilment of key competencies required to operate safely and effectively. They must also agree to abide by a code of ethics and maintain their standards for working with the public.[11]

Although there are many undergraduate and postgraduate degrees in nutrition in the UK, anyone can refer to him- or herself as a nutritionist without any qualifications. A person can legally describe themselves as a nutritionist and obtain qualifications such as a degree by mail from a non-accredited institution. The Association For Nutrition is the new professional body for the regulation and registration of nutritionists (including public health nutritionists, exercise nutritionists, and animal nutritionists). The AfN aims to protect the public, and promote wellbeing, by admitting to the UK Voluntary Register of Nutritionists only those who demonstrate high ethical and quality standards, founded on evidence-based science. The Association sets proficiency and competency criteria, promotes continuing professional development and safe conduct, and accredits university undergraduate and postgraduate courses.[citation needed]

Since 2002 the growth in the number of jobs for nutritionists has reportedly grown faster in the National Health Service (NHS) than in any other sector.[12] Despite it being recognized that nutritionists have an increasingly important role to play in health care in the UK, the NHS employs fewer dietitians each year and the profession itself is shrinking[13], with nutritionists being seen as 'non-essential' support staff.[citation needed]
