How To Become a Nutritionist: The Ultimate Guide

A career in nutrition is perfect if you’re interested in the health benefits that can come from thoughtful and informed eating. If you have a passion for healthy food and want to help others improve their wellbeing, you should consider becoming a nutritionist.

In this article, we’ll provide guidance on how to become a nutritionist in Australia, and point you towards the best study pathways to get you to your goals. We’ll also explain what professional nutritionists do, and give you tips for gaining experience in this industry. 

What does a nutritionist do?

The word ‘nutritious’ is frequently used in the discourse of food and healthy diets, but what does it actually mean? Harvard Health defines nutrition as the fuel your body needs ‘to maintain your brain, muscle, bone, nerves, skin, blood circulation, and immune system’. This fuel comes from the food we eat, and it serves as the ‘building blocks for muscles and tissues’. 

Our food intake can have a major impact on our health, with proper nutrition playing an important role in the prevention of non-communicable diseases (NCDs). According to the World Health Organisation, malnutrition – including both undernourishment and obesity – is a serious problem for individuals and communities across the globe.  

The role of a clinical nutritionist is to provide people with evidence-based information about healthy eating habits, and help them work towards their health goals. Nutritionists also provide advice to individuals and organisations about how diet is linked to wellbeing and disease prevention. 

The Nutrition Society of Australia explains that nutritionists essentially work as advisors and educators. Their duties can include:

  • Designing, coordinating, implementing and evaluating health interventions, with the goal of improving wellbeing through food and nutrition
  • Creating and implementing meal plans
  • Monitoring the progress of individual clients against their health goals
  • Adjusting dietary guidelines based on feedback and assessment

What is a registered nutritionist?

In Australia, there isn’t any legal protection over the use of the term ‘nutritionist’, meaning that anyone can use this title regardless of their educational background. 


However, the Nutrition Society of Australia has established a Register of Nutritionists for its members, to recognise those with accredited nutritionist qualifications. This ensures a high standard of professional practice within the industry.

What’s the difference between a nutritionist and a dietician?

Seek defines a nutritionist as someone who provides ‘evidence-based food and diet advice’, and a dietitian as ‘a qualified expert in diet, nutrition and health’. The key difference between the two is the level of education: you can become a registered nutritionist after completing a Bachelor of Food and Nutrition, but to become a dietitian you’ll need to complete some form of postgraduate study. 


As Dietitians Australia explains, the dietetic profession is heavily regulated. Professional dietitians need to have a dietetics degree from an Australian uni, and those with an Accredited Practising Dietitian (APD) credential remain committed to ongoing training throughout their careers.

Although use of the term ‘nutritionist’ isn’t regulated, studying a Bachelor of Food and Nutrition provides numerous advantages. Above everything else, getting qualified will make it possible for you to give the best possible health and nutrition advice, using information from reliable sources. 

The Australian Institute of Fitness explains that to become a certified nutritionist, you’ll need to gain qualifications that allow you to apply for accreditation. This will make it easier for you to succeed in your career, and it also means you can be covered for insurance.
