Article
Consumers’ tendency to waste suboptimal food poses challenges for sustainable food systems. In the case of aging produce, consumers often experience a conflict between the goals of not wanting to waste food and food safety. In addition to safety, perceived healthfulness can influence the decision between consumption and disposal of (suboptimal) foo...
Article
This paper analyzes the existing literature on the effect of attribute framing on consumers’ attitudes and intentions with regard to food products. Attribute framing includes a broader interpretation of gains and losses when a product attribute is presented in a dichotomous way, such as fat vs. lean or harm vs. benefit. Meta-analysis results for th...
