Abstract

Plant-based meat alternatives (PBMAs) such as the Impossible Burger imitate animal meat appearance, taste, feel, and texture. Part of their consumer appeal are the views that PBMAs are more environmentally friendly, reduce inhumane treatment of animals, and/or have preferred nutritional attributes. College-educated adults are one of the larger markets for these products. This cross-sectional online survey utilized the Theory of Planned Behavior to predict self-reported intakes of PBMAs among 536 undergraduates aged 18-25 at a Midwest university. Sixty-one percent had eaten PBMAs, and 17% wanted to try them. Twenty-two percent were uninterested non-consumers. Their top reason for not eating PBMAs was that they had no reason to decrease their meat intake. Multinomial logistic regression analysis showed subjective norms and positive attitudes about PBMAs increased the odds of more frequent intake, whereas non-consumers had less support from social contacts, but greater perceived behavioral control over general food access. Thus, those with supportive social influences, concerns about the environment, and animal welfare are more likely to consume PBMAs. More frequent PBMA consumption was observed among U.S.-born multicultural students, food insecure students, and those with less perceived behavioral control over food access. Future research should investigate the nuances between these associations further by examining the types of PBMAs consumed, their costs, and retail sources across student demographics.

摘要

植物性肉类替代品(PBMA),如“不可能汉堡”,模仿动物肉的外观、味道、口感和质地。它们对消费者的部分吸引力在于,人们认为PBMA更环保、减少了对动物的不人道对待,和/或具有更好的营养特性。受过大学教育的成年人是这些产品的较大市场之一。这项横断面在线调查利用计划行为理论来预测美国中西部一所大学536名18至25岁本科生中自我报告的PBMA摄入量。61%的人吃过PBMA,17%的人想尝试。22%的人是不感兴趣的非消费者。他们不吃PBMA的首要原因是没有理由减少肉类摄入量。多项逻辑回归分析表明,对PBMA的主观规范和积极态度增加了更频繁摄入的可能性,而非消费者从社会交往中获得的支持较少,但对一般食物获取的行为控制感更强。因此,那些受到支持性社会影响、关心环境和动物福利的人更有可能食用PBMA。在美国出生的多元文化学生、粮食不安全的学生以及对食物获取行为控制感较低的学生中,观察到更频繁的PBMA消费。未来的研究应该通过研究食用的PBMA类型、成本以及不同学生群体的零售来源,进一步调查这些关联之间的细微差别。
