Food consumption intersects with critical challenges including diet-related health issues, environmental sustainability, and inequality. Marketing influences consumer choices through information, pricing, interventions, and cultural meanings. Research has examined approaches like labelling, nudges, and reformulation, but these studies have developed separately across disciplines, leaving gaps in understanding how interventions interact and scale.
This special issue integrates perspectives from consumer behaviour, public health, economics, and sustainability to develop a comprehensive understanding of how marketing can support healthier and more sustainable food systems. It emphasizes the broader systems in which consumption occurs, including families, social networks, cultural practices, firms, policy structures, and value chains.
The issue welcomes empirical and conceptual research, reviews, and meta-analyses that bridge theory with practical implications for policy, industry, and society. Priority is given to interdisciplinary work examining intervention effectiveness, government policy, labelling, product reformulation, consumer adaptation, equity, and structural barriers.
