Overconsumption of red and processed meat is associated with a multitude of negative health outcomes. Previous research shows exposure to advertising messaging can influence dietary behaviors but research on the influence of advertising on diet, specifically, is scant. Theoretically informed by the Reasoned Action Approach, the present experiment randomly assigned participants to view a version of a print McDonald's advertisement that included meat imagery (a Big Mac), non-meat imagery (French fries), or no food (just the McDonalds' logo and slogan), which acted as a control. An online survey in the United States included 514 U.S. adults ( = 51 years). Participants exposed to meat imagery compared to the non-meat imagery reported a higher desire to eat meat. The meat imagery and control conditions were also significantly associated with increased cognitive accessibility of meat concepts, compared to when respondents were shown the no-meat condition. Desire to eat meat, but not the cognitive accessibility of meat concepts, was significantly associated with attitude, normative pressure, and perceived behavioral control for avoiding eating meat one day per week; these constructs predicted intention and willingness to avoid meat. Results indicate that exposure to meat imagery in advertising does have the potential to influence meat consumption behavior and also has implications for the use of meat imagery in persuasive messaging for public health campaigns.
过量食用红色肉类和加工肉类与许多负面健康后果有关。先前的研究表明,广告信息的接触会影响饮食行为,但关于广告对饮食的影响,特别是关于广告对饮食的影响的研究却很少。本实验以理性行为理论为理论基础,随机分配参与者观看麦当劳印刷广告的一个版本,其中包括肉类图像(巨无霸)、非肉类图像(薯条)或没有食物(只有麦当劳的标志和口号),作为对照。美国的一项在线调查包括 514 名美国成年人(平均年龄 51 岁)。与非肉类图像相比,接触肉类图像的参与者表示更想吃肉。与受访者看到无肉条件相比,肉类图像和对照条件也与肉类概念的认知可及性显著增加相关。想吃肉,但不是吃肉的认知可及性,与避免每周吃一天肉的态度、规范压力和感知行为控制显著相关;这些结构预测了意图和避免吃肉的意愿。结果表明,广告中肉类图像的接触确实有可能影响肉类消费行为,也对公共卫生运动中使用肉类图像进行有说服力的信息传递有影响。
