High sodium consumption, primarily from processed foods, contributes substantially to hypertension and cardiovascular disease in South Africa. Urban centres such as Johannesburg bear a significant burden from diet-related non-communicable diseases. This perspective aims to critically analyse the potential effects of implementing mandatory front-of-package sodium warning labels on processed foods in urban Johannesburg. It explores the interplay between this regulatory policy, consumer behaviour, and public health outcomes. As a perspective piece, it synthesises existing literature and policy analysis. The argument is constructed using relevant public health frameworks and principles from behavioural economics. Key insights: Analysis suggests prominent, mandatory warning labels could alter consumer purchasing patterns. Label design and clarity are paramount; simplified 'high in sodium' warnings are likely more effective than complex numerical information for driving healthier choices. Mandatory sodium warning labelling presents a feasible and potentially powerful public health policy tool for urban South Africa. Its success depends on culturally appropriate implementation and complementary public education. Policymakers should prioritise a standardised, mandatory front-of-package warning label system for high-sodium foods. This must be coupled with robust monitoring, evaluation, and public education campaigns. sodium reduction, front-of-package labelling, health policy, processed foods, non-communicable diseases, South Africa, consumer behaviour This perspective contributes to the discourse on regulatory public health nutrition in Africa by applying international evidence on warning labels to the specific socio-economic and retail environment of urban Johannesburg.
