CSIRO Healthy Diet Score

Put your diet to the test

Consider yourself a healthy eater? Now, you can take a scientifically validated test to find out for sure.

The CSIRO Healthy Diet Score is a free online assessment tool developed by our scientists in collaboration with Digital Wellness.

It's designed to assess the quality of your own diet against Australia's healthy eating guidelines and can help you improve your eating habits based on your results.

The free CSIRO Healthy Diet Score survey includes:

• an individual assessment of your diet
• personalised feedback on how you can improve your diet
• a free report which reveals how your diet compares to others' in Australia and your state, and of the same age and gender.

The CSIRO Healthy Diet Score report

More than 235,000 people have completed the CSIRO Healthy Diet Score survey since we launched it in 2015.

We first analysed the results a year-and-a-half later and released the CSIRO Healthy Diet Score report in 2016.

In 2023 we took a look back at all the results from 2015-2023 and found the average Australian diet score was 55 out of 100, suggesting that many of us should aim to improve our diet for a healthier lifestyle. The 2015-2023 CSIRO Healthily Diet Score report PDF (153 KB) has more insights into how Australians scored a relatively low collective score.
