BACKGROUND:
The escalating burden of non‑communicable diseases (NCDs), driven by the consumption of ultra‑processed foods high in sugar, salt, and saturated fat, underscores the urgent need for effective public health interventions.1,2 Front‑of‑package (FOP) labelling has emerged globally as a critical tool to inform consumers, reduce dietary risk factors, and advance the right to health.3,4 In South Africa, where inequities in food environments disproportionately affect vulnerable populations, FOP labelling represents both a public health necessity and a human rights obligation.5

METHODS:
This study adopts a human‑rights‑based approach to critically examine FOP labelling as a regulatory intervention. We reviewed international evidence on the effectiveness of interpretive warning labels,2,3 analysed global policy precedents,4 and assessed South Africa’s regulatory trajectory.5 The analysis situates FOP labelling within the broader framework of state obligations under international human rights law, emphasising its role in reducing information asymmetry and strengthening accountability in food systems.

RESULTS:
Evidence demonstrates that FOP warning labels, particularly clear, interpretive designs are effective in discouraging unhealthy purchases, shifting consumer behaviour, and improving population level dietary choices.2-4 Embedding FOP labelling within a rights‑based framework reframes it as a state duty rather than a discretionary policy, bolstering its legitimacy and providing a robust counter to industry opposition.6 This approach highlights the potential of FOP labelling to advance health equity and protect vulnerable groups disproportionately targeted by unhealthy food marketing.

CONCLUSIONS:
FOP labelling is a public health imperative rooted in the right to health. Its adoption represents a transformative step toward reducing NCDs, fulfilling states’ human rights obligations, and creating healthier food environments. For policymakers, researchers, and advocates, the priority is not whether to implement FOP labelling, but how to accelerate its adoption and ensure its effectiveness across diverse contexts.
