Public health strategies are placing increasing emphasis on the key role worksites can play in preventing illness and promoting health and well-being [6]. However, this
review highlights a critical lack of evidence regarding the most acceptable and cost-effective worksite health programmes. Strategies employed to promote healthy eating
to date have largely focussed on individual responsibility (education and behaviour change). Some programmes have implemented changes to worksite environments in order to make healthy choices easier but these have largely focussed on changing the physical environment, i.e. food availability, and have mostly failed to tackle the economic,
political, and socio-cultural aspects of the worksite. Greater use of frameworks for interventions that acknowledge the complexity of the environment and the need to
intervene at many levels may help to achieve more meaningful changes [38]. In particular, workplace canteens which frequently include a degree of food subsidisation
provide an ideal environment in which to test the potential of economic incentives to change food purchasing behaviour[39]. Evidence suggests that economic incentives
impact positively on dietary behaviour [40]; and favorable effects have been seen for weight loss [41,42], purchase of low-fat snacks [43], and self-reported fruit and vegetable consumption [44]. Changes to political (the rules) andsocio-cultural (social norms) aspects of the worksite also merit more consideration in future interventions.
