What are food media (messages)? A scoping review to clarify food media, food messages and food content in academic writing

PurposeThis scoping review aims to explore how "food media", "food messages" and "food content" are referred to in scholarly writing to enhance a shared understanding and comparability.Design/methodology/approachFollowing the PRISMA, ScR-guidelines, four scientific databases were screened on published manuscripts in academic journals, books and doctoral theses mentioning food media, content and messages within the prevalent meaning as in human communication.FindingsOf the 376 included manuscripts, only a small minority (n = 7) provided a conclusive definition of at least one of the three earlier-mentioned concepts; 40 others elucidated some aspects of food media, messages or content; however, they emphasized different and, sometimes even, contrasting aspects. In addition, the review explores in which disciplines the manuscripts mentioning food media, messages or content occur, which methodologies are used and what target groups and media are most common.Originality/valueBased on this aggregated information, a definition of food media, messages and content is proposed, aiming to enhance the comparability of diverse academic sources. This contribution invites scholars to critically reflect on the included media and content types when comparing studies on food media, messages or content.
