Eaters (consumers of food) are responsible for 60% of waste along the food cycle in developed countries. Programs that target individual and household food waste behavior change are essential to addressing such waste. School cafeterias worldwide offer an opportune microcosm in which to educate on food and nutrition skills and change related behavior. No Scrap Left Behind, a cafeteria food waste diversion program, was developed, piloted, and assessed based on measures of both direct and indirect food waste behavior, and attitudes, knowledge, and emotions related to food waste. Participants had positive attitudes towards food waste reduction, engaged in food waste diversion actions, had some knowledge of the impacts of wasted food, and considered their actions important to waste reduction generally. Food waste per student was decreased by 28% over the course of the first year of programming ( = 0.000967), and by 26% in the following year when measured a week before and a week after programming occurred ( = 0.0218). Results indicate that students were poised for food behavior change and that related programming did impact behavior in the short term. Programming may, therefore, help improve student attitudes and skills to develop long-term change as well, although future research should explore this specifically. In comparison with other research on cafeteria programming, results suggest that food waste diversion programming can positively impact students' dispositions and behaviors, and may be more effective when tailored to the specific population.
在发达国家,食物循环过程中60%的浪费是由食物消费者造成的。针对个人和家庭食物浪费行为改变的项目对于解决此类浪费至关重要。全球范围内的学校食堂提供了一个合适的微观环境,可用于开展食物和营养技能教育并改变相关行为。“不剩一点残渣”是一项食堂食物浪费转移项目,该项目基于对直接和间接食物浪费行为以及与食物浪费相关的态度、知识和情感的衡量标准进行开发、试点和评估。参与者对减少食物浪费持积极态度,采取了食物浪费转移行动,对浪费食物的影响有一定了解,并普遍认为他们的行动对减少浪费很重要。在项目开展的第一年,每名学生的食物浪费量减少了28%(P = 0.000967),在项目开展前后一周进行测量时,次年的食物浪费量减少了26%(P = 0.0218)。结果表明,学生已做好改变食物行为的准备,相关项目在短期内确实对行为产生了影响。因此,尽管未来的研究应专门对此进行探索,但该项目可能也有助于改善学生的态度和技能,以实现长期改变。与其他关于食堂项目的研究相比,结果表明食物浪费转移项目可以对学生的倾向和行为产生积极影响,并且针对特定人群进行定制时可能会更有效。
