The Case for Mandatory Health Star Ratings
Public health organizations are advocating for the mandatory inclusion of health star ratings on all packaged foods, citing a growing obesity crisis that demands urgent action. These ratings, which range from half a star to five stars, were introduced to help consumers quickly compare the nutritional value of similar products. However, their current voluntary nature has led to inconsistent application, with less than 40% of intended products displaying the rating.
The Food Standards Australia New Zealand (FSANZ) is considering making the system mandatory, as the uptake has fallen significantly below the 70% target set by food ministers in Australia and New Zealand. This lack of participation has prompted renewed discussions about implementing a standardized approach to nutrition information.
Consumer Confusion and Industry Concerns
Research conducted for FSANZ revealed that most consumers rarely notice or use the health star rating, while some consult it for specific items like lunch box snacks or children’s breakfast cereal. Despite this, many shoppers support making the ratings compulsory, believing it would increase confidence in the system.
During a meeting in February, ministers from across Australia and New Zealand expressed concern over the low adoption rate of the ratings. They agreed, by majority, to request FSANZ to prepare a proposal for a mandatory system. In May, Australia’s Assistant Minister for Health, Rebecca White, announced the opening of public submissions, emphasizing the importance of clear and simple information on food packaging to help consumers make informed choices.
Expert Support for Mandatory Labels
Doctors and public health organizations, including the Cancer Council and Diabetes Australia, argue that mandatory health star ratings could lead to healthier choices and improve public health outcomes. The Australian Medical Association (AMA) is particularly concerned about the ongoing obesity crisis, noting that rates have increased for over 25 years and will continue without decisive action.
AMA federal president Danielle McMullen stated that the voluntary system has not been effective, with industry uptake hovering at just 36%. She emphasized that the system must be led by government and free from industry interference. Obesity, she said, is a major risk factor for chronic conditions such as type 2 diabetes, heart disease, and some cancers.
Justine Cain, CEO of Diabetes Australia, highlighted the need for a food labelling system that helps busy Australians make healthy choices. The Heart Foundation also supports consistent food labelling as a critical public health measure.
Industry Resistance and Practical Challenges
The Australian Food and Grocery Council argues that the current voluntary system is working and that mandating health star ratings would impose significant costs on businesses. Duncan Craig, director of health and regulatory affairs at the council, pointed out that label changes are complex, especially for businesses with hundreds of product variants requiring detailed assessments.
He noted that even small tweaks to the rating system could have wide-ranging impacts on operations. Additionally, the algorithm used to determine health star ratings has faced criticism, particularly from the juice industry, which claims diet soft drinks receive higher scores than 100% fruit juice.
Revising the Algorithm
The AMA suggests that the algorithm should be expanded to address concerns about how scores are determined. While mandating the system is a priority, regular reviews of the algorithm will be essential. Health specialists also recommend considering processing methods when calculating ratings.
However, Dr. Craig of the Australian Food and Grocery Council argues that there is insufficient evidence linking processed food to poor health. He warns that incorporating processing levels could negatively impact nutritious products such as wholegrain bread and certain yoghurts.
A Decision in 2027
Despite these challenges, the push for mandatory health star ratings continues. A decision from FSANZ on the proposal is expected in 2027 following public consultation and reviews. The debate highlights the tension between public health goals and industry concerns, as stakeholders work to find a balanced solution that benefits both consumers and businesses.
