Abstract. The present studies examine how culturally held stereotypes about gender (that women eat more healthfully than men) implicitly influence food preferences. In Study 1, priming masculinity led both male and female participants to prefer unhealthy foods, while priming femininity led both male and female participants to prefer healthy foods. Study 2 extended these effects to gendered food packaging. When the packaging and healthiness of the food were gender schema congruent (i.e., feminine packaging for a healthy food, masculine packaging for an unhealthy food) both male and female participants rated the product as more attractive, said that they would be more likely to purchase it, and even rated it as tasting better compared to when the product was stereotype incongruent. In Study 3, packaging that explicitly appealed to gender stereotypes (“The muffin for real men”) reversed the schema congruity effect, but only among participants who scored high in psychological reactance.

Focusing on how children make food choices, this article presents research to support efforts to meet children’s information needs when it comes to food packaging. Using focus groups, the authors examine children’s perspectives on ‘most healthy’ and ‘least healthy’ packaged food. Findings reveal that children understand whole foods as ‘healthy’ foods, use the Nutrition Facts label to guide their decisions, and interpret package visuals as literal descriptions of what a food contains. These findings provide evidence-based support to improve food packaging design regulations. Finally, the authors call for transparent visual communication strategies, which aim to improve the critical thinking skills of children, and provide a foundation for informed decision-making across a lifetime.
