Pretty Healthy Food: How and When Aesthetics Enhance Perceived Healthiness

Marketers frequently style food to look pretty (e.g., in advertising). This article investigates how pretty aesthetics (defined by classical aesthetic principles, such as order, symmetry, and balance) influence healthiness judgments. The author proposes that prettier food is perceived as healthier, specifically because classical aesthetic features make it appear more natural. In a pilot, six main studies and four supplemental studies (total N = 4,301) across unhealthy and healthy, processed and unprocessed, and photographed and real foods alike, people judged prettier versions of the same food as healthier (e.g., more nutrients, less fat), despite equal perceived price. Even given financial stakes, people were misled by prettiness. In line with the proposed naturalness process, perceived naturalness mediated the effect; belief in a "natural = healthy" connection moderated it; expressive aesthetics, which do not evoke naturalness, did not produce the effect (despite being pretty); and reminders of artificial modification, which suppress perceived naturalness, mitigated it. Given that pretty food styling can harm consumers by misleading healthiness judgments for unhealthy foods, managers and policy makers should consider modification disclaimers as a tool to mitigate the "pretty = healthy" bias.
