Sweet little lies: Sugar myths vs facts
The truth might not be what you're expecting...
If you’ve ever had health problems, weight issues or a food intolerance, you may have considered seeing a dietitian or nutritionist to help you make changes to your diet. But what’s the difference between the two, and why is their advice likely to be better than what you can find online?
The easiest way to wrap your head around the difference between a dietitian vs a nutritionist is to think of dietetics as a specialisation on top of nutrition studies, much like a heart surgeon is a specialisation on top of a medical degree.
To complete a qualification in this area, a dietitian needs to have tertiary qualifications from an accredited university program and must have completed a course of study that makes them eligible for membership of Dietitians Australia as an Accredited Practising Dietitian. To be an Accredited Practising Dietitian, dietitians must also commit to continuous professional development, ensuring they continue to give up-to-date and safe advice.
University of Newcastle Laureate Professor in Nutrition and Dietetics, Clare Collins, warns that the term ‘nutritionist’ isn’t regulated.
When you consult a nutritionist or dietitian, she advises making sure they are a registered member of at least one of the following: Dietitians Australia and/or The Nutrition Society of Australia (NSA). Both have searchable databases to check if the health professional you’re thinking about seeing is registered.
According to Dietitians Australia, a nutritionist is a tertiary-qualified nutrition professional with the expertise to provide a range of evidence-based nutrition services related to nutrition, public health nutrition, policy and research as well as community health.
Dietitians have qualifications that mean they can work in any of the areas nutritionists work, but they are also permitted to provide medical nutrition therapy for a broad range of diseases and health problems to help people manage their conditions – whether it’s diabetes, gastrointestinal disorders, food allergies or cancer.
Dietitians can work with you to personalise specific diets or eating plans to meet your health and wellbeing needs. They can offer support and motivation when you need it, and provide additional resources to help you implement the recommendations as meal ideas.
While dietitians can’t prescribe drugs or take blood tests, they can offer advice about tracking your diet-related health that you can take to your GP to discuss.
Dietitians help with a range of health goals, including people who are:
Those who’ll benefit from seeing an Accredited Practising Dietitian also include:
“If there’s something you can’t eat due to an intolerance, food allergy or health condition, you’ll definitely benefit from seeing an Accredited Practising Dietitian to make sure you’re on the right track in terms of eating patterns that meet your nutrient needs,” Professor Clare says.
Along with any medical condition requiring you to change the way you eat, seeing a dietitian is wise if you’ve been diagnosed with an inflammatory bowel condition, celiac disease, diabetes or heart disease.
“These are some of the common nutrition-related conditions that people don’t tend to think about but would really benefit from getting a personalised nutrition plan to manage,” Professor Clare says.
Pregnancy and pre-pregnancy are key life stages where nutrient needs can change the most dramatically.
Despite the overwhelming number of well-meaning apps and websites dedicated to pregnancy and nutrition, few offer evidence-based advice, Professor Clare warns.
An Accredited Practising Dietitian can cut through the reams of advice available online and consider your individual needs to provide personalised advice and support you can trust.
Older adults can also benefit from seeing a dietitian, but they don’t usually do so until they are admitted to hospital or an aged care facility, Professor Clare says.
“As you age, your total energy expenditure goes down in line with lower muscle mass; you don’t move as much so you don’t need as much food,” she explains. “Your appetite changes too, but the challenge is that your nutrient requirements stay the same or increase.”
Your protein requirements become higher in old age, for example, so you need to be proactive about preserving your muscles.

A nutritionist is a person who provides advice on matters relating to food. Their work may involve designing, implementing and evaluating a range of population health interventions to improve health and wellbeing through food and nutrition.
Nutritionists may also work in a variety of other occupations including research, as nutrition consultants, in public health or as food technologists. However, they are not qualified to provide medical nutrition therapy advice; this is the role of dietitians.
If you’re interested in consulting a nutritionist (remembering that dietitians are also qualified nutritionists), it’s a good idea to check that they’re registered with the NSA.
The NSA only registers nutritionists who are appropriately qualified. Their members can include nutrition scientists, food scientists, nutritionists in public health or private practice, as well as some dietitians and complementary therapists in private practice.
Full registration requires a degree or postgraduate degree in nutrition as well as three years’ experience working as a nutritionist. Nutritionists who are also Accredited Practising Dietitians are registered with Medicare.
