Sugar-coated sustainability: Deceit, disclosure, and regulation in ultra-processed foods

Ultra-Processed Greenwashing

Ultra-processed foods dominate modern diets in wealthy nations, supplying roughly 50 per cent of daily calories for the average Australian and comparable shares in the United States and United Kingdom. The November 2025 Lancet Series crystallised the scientific case: these industrially formulated products displace fresh and minimally processed foods, degrade overall diet quality through hyper-palatability and nutrient imbalances, and elevate risks of obesity, type 2 diabetes, cardiovascular disease, certain cancers and depression.

Policy momentum accelerated in late 2025 and early 2026. America's updated Dietary Guidelines, released in January, explicitly advised limiting highly processed items for the first time. This followed the FDA and USDA's July 2025 Request for Information on a uniform definition, whose comments closed in October. At state level, Arizona's additive bans in schools begin with the 2026-27 year, while California's framework aims to restrict ultra-processed foods in school meals by 2035, with implementing regulations due by 2028.

The stakes are concrete and immediate. Diet-related diseases already strain healthcare budgets by hundreds of billions annually worldwide. Ultra-processed items drive substantial shares of food-system greenhouse-gas emissions, land use and packaging waste through energy-intensive manufacturing and global supply chains. Children in affected US school districts will encounter changed meal offerings; low-income households, often most reliant on affordable ultra-processed options, risk higher costs if reformulation or labelling mandates raise prices without parallel support for whole-food alternatives.

Less visible are the tensions within sustainability governance itself. Producers increasingly market ultra-processed ranges with claims about plant-based ingredients, reduced-carbon packaging or regenerative sourcing. Yet these disclosures frequently sidestep the core industrial processing that undermines both human health and planetary boundaries. In Australia, where a national food strategy is being shaped by an industry-heavy advisory council appointed in late 2025, such dynamics risk entrenching the status quo. European Union experiments with green-claims directives offer a parallel test case, but enforcement gaps persist amid corporate lobbying that frames stricter rules as threats to innovation and food security.
