What does a registered nutritionist do?

Our understanding of foods and the role of diet in overall health changes in response to research and technological advancement, so registered nutritionists must keep up to date with advances in food science and nutrition in order to provide current advice to their clients. A registered nutritionist consults with a client on their eating behaviours, performing an assessment of their current diet, their health and fitness goals and works with them to structure a diet plan specific to their needs. In many cases, clients will seek the advise of a nutritionist for a specific reason, such as losing weight, improving fertility or addressing allergies. Nutritionists also carry out work in a research setting, looking at technological innovations or clinical studies of diet in groups of people.

There are multiple career options open to those who study nutrition science. Nutritionists may chose to undertake further qualifications, pursue research positions, devise public health programs or specialise their practice to target specific health conditions.

Exercise Scientist

Athletes have strict dietary requirements that align with their high level of physical exertion and activity. An exercise scientist can structure a diet plan to complement an associated exercise plan ensuring optimal physical health and performance in an athlete.

Environmental health officer

Environmental health officers assess environmental implications on human health. Negative impacts of pollution or asbestos can adversely affect human health. Environmental health officers monitor and analyse health and actions that can be put in place to counteract this.


To become a dietician, a nutritionist must undergo further study of clinical nutrition and dietetics. As dietetics is a highly specialised field, dieticians are qualified to give medical advice and detailed insight that nutritionists cannot.
