While many people declare an intention to eat and snack more healthily, a large body of research has found that these intentions often do not translate into actual behavior. This failure to fulfil intentions is regularly attributed to the obesogenic environment, on which basis it is assumed that changing the food environment may lead to more healthy snacking behavior. To test this premise in real life practice, the present research project investigated whether making a healthy snack easy-to-access in an urban environment characterized by unhealthy snacking would support people in their intentions of purchasing more healthy snacks. The urban snack project consisted of three phases. In Phase 1, a hotspot location for unhealthy snacking was determined by using a Global Positioning System to track people's snacking locations anda survey to verify the location . In Phase 2, an attractive snack was developed that met consumers' criteria of what constituted a healthy and tasty snack, together with corresponding branding that also included a small food truck from which to sell the newly developed snacks. In Phase 3, the snack was sold from the food truck located at the previously determined unhealthy snacking hotspot. We counted the number of snacks sold and canvassed people's opinions about the snack and its branding, finding that in spite of people's appreciation for the snack, the food truck, and the branding, actual sales of the snack were very low. In the Discussion, we name predominant eating and purchasing habits as possible reasons for these low sales. Future research could focus on placing the healthy snack directly beside people's habitual snack purchase location to ensure that the new choice gets better recognized. Overall, the findings suggest that merely placing healthy snacks more prominently in people's food environment is not sufficient to lead people to snack more healthily.
虽然许多人声称有意吃得更健康,吃更多健康的零食,但大量研究发现,这些意图往往没有转化为实际行为。这种意图无法实现通常归因于致肥胖环境,基于这一假设,改变食物环境可能会导致更健康的零食行为。为了在现实生活实践中检验这一前提,本研究项目调查了在以不健康零食为特征的城市环境中,使健康零食更容易获得是否会支持人们购买更多健康零食的意图。城市零食项目包括三个阶段。在第 1 阶段,使用全球定位系统跟踪人们的零食地点,并通过调查验证地点,确定了一个不健康零食的热点位置。在第 2 阶段,开发了一种有吸引力的零食,该零食符合消费者对健康和美味零食的标准,同时还包括相应的品牌,其中还包括一个可以销售新开发的零食的小型食品车。在第 3 阶段,从之前确定的不健康零食热点位置的食品车销售零食。我们统计了销售的零食数量,并征求了人们对零食及其品牌的意见,发现尽管人们对零食、食品车和品牌表示赞赏,但零食的实际销售量非常低。在讨论中,我们将主要的饮食和购买习惯命名为销售低迷的可能原因。未来的研究可以集中在将健康零食直接放在人们习惯性购买零食的位置旁边,以确保新的选择得到更好的认可。总的来说,研究结果表明,仅仅将健康零食更突出地放在人们的食物环境中,并不足以促使人们更健康地吃零食。
