Careers in nutrition and dietetics

Nutritionist or dietitian. What's the difference?


Nutritionists are qualified to provide evidence-based advice on matters relating to food and its impact on human health. Nutritionists mostly work in group or community settings and often have a focus on community and population health. They're able to provide expert advice and services across a range of sectors such as the food industry, public and community health, media, government and education.

Many current healthcare professionals including fitness professionals, nurses and psychologists choose to study nutrition to complement their area of expertise, broaden their knowledge and acquire the skills to provide further advice to their patients and clients. Fitness professionals study nutrition to gain an understanding of food sciences to complement their exercise expertise, whereas psychologists may see the benefit in studying nutrition to gain in depth knowledge about how our diet can affect our mental health.


Dietitians may work in any of the same settings and roles as nutritionists, however, they have additional accredited qualifications that allow them to work one-on-one with patients in a clinical context, including in hospitals, private clinics and residential care centres. Dietitians are able to provide individuals with medical advice and medical nutrition therapy, and are able to prescribe treatments for many conditions such as diabetes, allergies, cancer and obesity.



To practise as a dietitian in Australia, you must become accredited by Dietitians Australia (as an Accredited Practising Dietitian).

Nutritionists can register with the Nutrition Society of Australia.
