Addressing equity gaps in healthy food access: A meso-level model of food innovation, distribution and acceptance
Method: We draw upon extant research and literature on food environments, distribution, access, acceptability and culture concentrating on regional and socio-demographic differences. Using this, we construct a stylized meso-level behavioral dynamic nutritional food market transformation model following the system dynamics methodology. Using geo-spatial point-of-sales and socio-demographic data from the Quebec, we apply the model to the Canadian context. Modeling small and larger scale firm-, government- and social sector-led actions and policies targeting healthy food, we identify mechanisms that underlie equity gaps and explore high leverage interventions to overcome this.
Results: Simulation results show that classic single-actor market-led innovations have limited success in low-income areas due greatly to their poor food distribution networks, marketing infrastructure, and consumer acceptance which, resulting from low marginal benefit to improve each, collectively sustains disadvantages for low-income areas. Additionally, uptake is constrained by inertia from habitualization and group normsthat entrench existing food behavior. These factors, while significant causes of market failures, through convergent multi-stakeholder innovation, can also serve as significant leverage points.
Conclusions: Community-based nutritional education and infrastructure improvement interventions and directives directly targeted to these levers in underserved neighborhoods assist in overcoming accessibility barriers and sustaining innovation to overcome the inclusiveness gap.
