None of the evaluated articles addressed a multidimensional
issue with a multidimensional intervention approach.
But food especially has a critical connection to economic
and environmental concerns which, when implemented into
a healthy eating intervention, could yield positive results
across the “triple bottom line”: economy, environment, and
health [54]. Gittelsohn and Lee [53] offer important motivation
for a multidimensional intervention which engages
multiple aspects of the food system: “often the healthy eating
discussion focuses on the retailer-consumer food system,
but engagement with retailers, distributors, producers, and
manufacturers could also greatly influence dietary outcomes”
(page 64). Designing a behaviour change tool which
addresses more than just a health issue, such as obesity,
through a multidimensional approach is thus both empirically
novel and a significant contribution to the literature on
health promotion and the theory on behavioural economics.
