A study by The George Institute of Global Health has found that Australia's voluntary sodium reformulation programme, the Healthy Food Partnership, could only reduce sodium purchases by 50mg/day per capita, despite covering 16.1% of all unique products. The programme, which sets sodium targets for 27 food categories, was found to have limited impact as 47% of products already meet the targets. The study suggests that adopting the UK's more stringent and wider sodium targets, or a gradual reformulation approach, could potentially double the reduction in sodium purchases. The study underscores the need for more robust targets to encourage more products to reformulate and highlights the importance of monitoring and potentially mandating the programme if voluntary efforts fail.
