Online comments slam Australia's health star ratings

Intertek Inform said most online comments it analysed about Australia's Health Star Rating system expressed confusion or dissatisfaction, as the country moves towards making the front-of-pack food labelling scheme mandatory.

The company reviewed 282 relevant comments from 1,259 posts and replies across eight Reddit threads on r/australia. It found 76.6% of opinions were against the system, 13.5% were mixed or neutral, and 7.8% were in favour.

The analysis suggests scepticism about how well the star-based label reflects the healthiness of packaged food. The most common criticism, appearing in 47.2% of negative comments, was that the ratings were misleading. Users pointed to cases where heavily processed products appeared to score better than whole foods.

Manufacturer influence was the second most common concern, appearing in 13.9% of critical comments. Lack of nutritional context followed at 13%, reflecting complaints that a single score could not capture a product's wider nutritional profile.

Other concerns included how products are compared across categories, mentioned in 7.9% of negative comments, and the influence of lobbyists on the policy framework, cited in 6.9%. A smaller share of users questioned the underlying algorithm or said they preferred alternative labelling systems.

Consumer reaction

Support for the Health Star Rating system was limited in the online sample, but comments in favour tended to focus on its simplicity. Among supportive posts, 27.3% said the system reflected a product's healthiness, while 22.7% said it helped shoppers compare products in the same category.

Another 18.2% of favourable comments said the scheme was simple but could be improved. Smaller shares said it could guide healthier choices, improve consumer understanding, or counter misleading marketing.

The Health Star Rating system has been used on packaged food in Australia as a voluntary labelling scheme, giving products a score from half a star to five stars. Debate has centred on whether its formula gives too much weight to some nutrients while failing to reflect levels of processing or overall ingredient quality.

Intertek Inform said the review was intended as a snapshot of online discussion rather than a representative measure of public opinion. It noted that Reddit users are a self-selected audience and may skew towards people who are more digitally active or more strongly opinionated than the wider population.

Method and limits

The study used a three-stage large language model process to classify stance and identify themes in the comments. Themes were derived from the data rather than set in advance, and the company said it carried out spot checks during the process.

The methodology places the findings within the growing field of AI-assisted analysis of public commentary, but it also raises questions about consistency and interpretation in qualitative labelling. The limited sample size and platform-specific source mean the results are better read as an indication of discussion in one online community than as a broad national verdict on the scheme.

Still, the figures illustrate the challenge facing food regulators and manufacturers as labelling policy tightens. If mandatory display of the Health Star Rating expands across packaged food, public trust in how the score is calculated is likely to come under closer scrutiny.

Dr Anand Shankaran, Vice President at Global Intertek Inform and SAI Assurance Australasia, commented on the findings.

"Clear, consistent and credible labelling isn't a 'nice to have', it's the foundation of every spending decision a shopper makes at the supermarket, and that's why labelling is an important communication tool for business to consumers," said Dr Anand Shankaran, Vice President, Global Intertek Inform and SAI Assurance Australasia.

"What this online commentary highlights is that many consumers are navigating real confusion around food labelling, and that's an important signal for the industry. When people find it difficult to interpret what a label means, it becomes harder for them to make confident, informed choices at the supermarket. That's why balanced regulatory guidance and clear, trusted labelling standards matter so much," Shankaran said.
