A large body of research has focused on understanding how online content and disordered eating behaviors are associated. However, there is a lack of comprehensive studies investigating digital food content's influence on individuals with eating disorders. We conducted two rounds of studies (N=23 and 22, respectively) with individuals with binge eating disorder (BED) or bulimia nervosa (BN) to understand their motivations and practices of consuming digital food content. Our study reveals that individuals with BED and BN anticipate positive effects from food media to overcome their condition, but in practice, it often exacerbates their disorder. We also discovered that many individuals have experienced a cycle of quitting and returning to digital food content consumption. Based on these findings, we articulate design implications for digital food content and multimedia platforms to support vulnerable individuals in everyday online platform interactions.

翻译：大量研究致力于理解在线内容与饮食失调行为之间的关联，但针对数字食品内容对饮食失调症患者影响的全面研究仍显不足。我们开展了两轮研究（分别涉及23名和22名参与者），对象为暴食症或神经性贪食症患者，旨在了解其消费数字食品内容的动机与实践。研究揭示，暴食症与神经性贪食症患者虽期望食品媒体能对其状况产生积极影响，但实际中这些内容往往加剧其病症。我们还发现，许多患者经历了反复放弃与回归数字食品内容消费的循环。基于这些发现，我们提出了针对数字食品内容与多媒体平台的设计启示，以支持脆弱群体在日常网络平台互动中的需求。
