Imagine giving a bag of chips a glowing 3.5-star rating. Sounds absurd, right? But that’s exactly what’s happening with Australia’s Health Star Rating system, and it’s sparking a heated debate about whether this tool is truly helping consumers make healthier choices—or if it’s being manipulated by the food industry. Here’s the shocking truth: the system meant to simplify healthy eating might actually be misleading you.
Launched in 2014 as a joint initiative between Australia and New Zealand, the Health Star Rating system was designed to rate packaged foods and drinks on a scale of 0.5 to 5 stars based on their nutritional profile. Manufacturers use an online calculator, inputting four 'negative' nutrients—kilojoules, saturated fat, sugars, and sodium—and balancing them with four 'positive' components like fiber, protein, and fruit and vegetable content. Sounds straightforward, right? But here’s where it gets controversial: the system doesn’t account for ultra-processed foods or artificial sweeteners, allowing heavily processed items like chips and zero-sugar sodas to score surprisingly high ratings.
Take this for example: a bag of chips can score up to 3.5 stars, while a zero-sugar soft drink might also hit the same mark. Meanwhile, a Milo snack bar gets 4 stars, and a liquid breakfast product like Up & Go can reach 4.5 to 5 stars. And this is the part most people miss: only 35% of intended products in Australia displayed a star rating as of November 2023, with low-rated products rarely showing their scores. Critics argue that manufacturers are cherry-picking which products to label, using the system as a marketing tool rather than a genuine guide for consumers.
Nutrition experts like Sarah Dickie from Monash University point out that the algorithm’s flaws allow unhealthy foods to appear healthier than they are. ‘You can still have a junk food product and add enough ‘good’ ingredients to balance it out,’ she explains. ‘But it’s still junk food.’ Ultra-processed foods, linked to heart disease and diabetes, slip through the cracks, and artificial sweeteners—which may promote unhealthy taste preferences—aren’t even factored in. Is this system truly serving the public, or is it serving the industry?
Surveys show that consumers crave transparency. A 2024 VicHealth survey revealed that nutrition information is the second most important factor in food purchases, yet many doubt the reliability of food labels. Similarly, 82% of Australians in a 2023 Cancer Council survey believe Health Star Ratings should be on all packaged foods, with two-thirds supporting a mandatory system. But should a flawed system be forced upon everyone? Experts are divided.
Magriet Raxworthy of Dieticians Australia supports mandating the current system but acknowledges room for improvement. She emphasizes better public education on how to interpret the ratings correctly, noting that many compare products across different categories, which defeats the system’s purpose. On the other hand, advocates like Dickie argue that the system is fundamentally flawed and should be replaced with a warning-based approach, clearly labeling unhealthy foods instead of ranking them.
As food ministers prepare to meet early next year to decide the system’s future, the stakes are high. If mandated, it could take years to see changes on shelves. But with ultra-processed foods dominating diets and health issues on the rise, can we afford to wait? Here’s a thought-provoking question for you: Should we fix the Health Star Rating system, replace it entirely, or scrap it and start over?
