CSIRO Healthy Diet Score

Australians are now able to measure the quality of their eating habits using a simple online assessment tool, the CSIRO Healthy Diet Score.

The CSIRO Healthy Diet Score is a scientifically validated survey that assesses a person’s diet against Australia’s healthy eating guidelines, providing a single dietary quality score on a 100-point scale.

The CSIRO Healthy Diet Score is free and can be completed in less than 10 minutes.

In 2016, we will use data from the Healthy Diet Score to extend our research on how food consumption contributes to our environmental footprint, allowing researchers to better quantify the impact of how much we eat and what we eat. CSIRO researchers will collate and analyse the data and expect to release the findings later in the year. 

Since its launch in May 2015, more than 70,000 people have taken the survey. In August 2015, we released our findings, giving Australians a C, and a score of 61 out of 100. Read more about the findings in the Aussie diets fail the test media release.

An individual’s score is based on food variety, frequency, quantity as well as attributes such as age and gender. In addition to their overall score, people who complete the online assessment will receive feedback on how they can improve their diet.

The launch of the Healthy Diet Score follows more than three years of research by CSIRO and University of South Australia and is capable of providing a similar evaluation to other more complex diet assessment methods such as weekly tracking of food intake.

The Healthy Diet Score is free and can be completed in less than 10 minutes.

CSIRO’s lead researcher, Professor Manny Noakes, has been heavily invested in the development of the Healthy Diet Score and says most people overestimate how healthy their food intake is. The online assessment aims to provide guidance on how to improve eating habits and to serve as a reminder that there is always room for improvement when it comes to making healthy food choices.  

“With no existing benchmarks for people to quickly assess their eating behaviour, we developed the Healthy Diet Score to provide a simple and reliable measurement for people to better understand the quality of their diet,” said Professor Manny Noakes, Research Director for CSIRO’s Food and Nutrition Flagship and co-author of the CSIRO Total Wellbeing Diet.

“A nutritious diet means eating a wide range of foods associated with a healthy lifestyle, however too often people will focus on a single food type or nutrient when looking to improve their diet. We know from previous research conducted that on average people are not eating enough fruit, vegetables and diary and are eating too much junk food.

“What the Healthy Diet Score does is provide individuals with an assessment that is relevant only to them, taking into consideration other people of the same age and gender, to let them know how their diet quality is measuring up,” said Professor Noakes.

Key features of the Health Diet Score include:

  • An individual assessment of your diet quality
  • Personalised feedback on how you can improve your diet quality
  • A free report which reveals how your diet quality measures up compared to others of the same age, gender, generation, profession as well as people from the same State and across the country.
