Front-of-pack nutrition labelling tools are designed to help consumers make healthier food choices and support a balanced diet.

One such tool is Australia's Health Star Rating (HSR) system, which assigns foods a rating from 0.5 to 5 stars. These ratings are based on the presence of "risk" nutrients (such as saturated fat, sugar, and sodium) and "positive" components (like fibre and protein, and fruit, vegetables, nuts, and legumes).

But how accurately does the HSR reflect the healthfulness of products? And how well does it align with dietary guidelines?

In this episode, we speak with Associate Professor Sara Grafenauer, who shares insights from her recently-published research. Her study explored three potential modifications to the HSR algorithm, aiming to improve how nuts and nut-containing products are rated, to ensure better alignment with current dietary guidance and scientific evidence.

Sara walks us through the findings from the tested scenarios, highlights some unintended effects, and offers her recommendations for improving public trust and confidence in Australia's HSR system.

Key take-outs:

• The current HSR algorithm can unfairly penalise certain types of nuts due to their energy density and saturated fat content, leading to lower star ratings compared to other nuts.
• These inconsistencies may confuse consumers, as the ratings are not always reflective of current scientific evidence or dietary recommendations.
• Simple adjustments to the HSR algorithm could significantly improve the ratings of plain nuts and nut-containing foods, better aligning them with established dietary guidance.
