Health Star Rating

Health Star Rating. The Health Star Rating is a voluntary front-of-pack labelling system used in Australia and New Zealand designed to help consumers quickly compare the nutritional value of packaged foods. Developed by the Australian Government, New Zealand Government, and state health authorities, it assigns a rating from ½ a star to 5 stars. The system aims to encourage healthier food choices within categories like breakfast cereals, yoghurt, and canned foods.

Overview

The system presents a visual summary of a product's overall nutritional profile, with more stars indicating a healthier choice. Managed by the Australia and New Zealand Ministerial Forum on Food Regulation, its implementation is overseen by the Department of Health and Aged Care in Australia. The label is typically found on the front of packaging for products ranging from Weet-Bix to Sanitarium items, providing an at-a-glance assessment to guide shoppers in Coles and Woolworths.

Development and implementation

Development began following a 2011 recommendation by the FSANZ review of food labelling law and policy. A five-year timeline for implementation was agreed upon by the Council of Australian Governments in 2014. Key stakeholders in the process included the Heart Foundation, Cancer Council Australia, and industry groups like the Australian Food and Grocery Council. The system was formally launched after extensive consultation and pilot studies, with oversight from the New Zealand Ministry for Primary Industries.

Calculation methodology

The rating is calculated using a complex algorithm that considers both risk and beneficial nutrients. Points are deducted based on energy, saturated fat, total sugar, and sodium content, as outlined by the Nutrient Reference Values for Australia and New Zealand. Points are added for beneficial components like dietary fibre, protein, and the proportion of fruit, vegetable, nut, and legume content. The final score, calibrated using the Food Standards Code, determines the star rating, with specific adjustments for categories like cheese and oils.

Reception and criticism

The system has received mixed reactions from public health bodies and academics. Organizations like the World Health Organization have endorsed front-of-pack labelling in principle, while the George Institute for Global Health has published analyses of its performance. Criticism has focused on the algorithm, with some researchers arguing it can award high ratings to ultra-processed foods like certain breakfast cereals and flavoured yoghurt. Groups including the Public Health Association of Australia and New Zealand Medical Association have called for mandatory application and algorithm reforms.

Impact and effectiveness

Studies on consumer behaviour, including research from the University of Sydney and University of Auckland, suggest the system influences purchasing decisions, particularly when combined with education campaigns. Its effectiveness in driving product reformulation has been noted by FSANZ and industry analysts, with companies like Nestlé and Unilever modifying recipes to achieve higher ratings. Ongoing monitoring and a formal review process, involving bodies like the Australian Bureau of Statistics, assess its impact on dietary patterns and public health outcomes in the region.
