BACKGROUND/OBJECTIVES: Appearance-related social media, such as "thinspiration" and "fitspiration" posts, have been shown to contribute to poor body image and disordered eating. Food-related social media is becoming increasingly popular; however, far less is known about its relationship to body image and disordered eating.
The current review searched PsycNet and PubMed (Medline) for all the literature examining food-related social media and its relationship with body image and/or disordered eating outcomes.
From 796 initial hits, the search identified 16 relevant studies. The study designs and types of media examined varied widely, including mukbang videos, food blogs, and "What I Eat In A Day" videos. Findings on the relationship between food-related social media and outcome variables were quite mixed, perhaps speaking to the wide variety of media included in the review.
The existing literature is sparce, but overall, it suggests a potential relationship between food-related social media, negative body image, and disordered eating. Additional experimental research is needed to clarify outcomes for different media types (e.g., food blogs versus mukbang videos) and to determine the direction of causality for each.
背景/目的：与外貌相关的社交媒体，如“瘦激励”和“健身激励”帖子，已被证明会导致不良的身体形象和饮食失调。与食物相关的社交媒体越来越受欢迎；然而，人们对其与身体形象和饮食失调之间的关系了解甚少。
本综述在PsycNet和PubMed（Medline）中搜索了所有研究与食物相关的社交媒体及其与身体形象和/或饮食失调结果之间关系的文献。
从最初的796条搜索结果中，筛选出16项相关研究。所研究的媒体的研究设计和类型差异很大，包括吃播视频、美食博客和“我一天吃了什么”视频。关于与食物相关的社交媒体和结果变量之间关系的研究结果喜忧参半，这可能与综述中纳入的媒体种类繁多有关。
现有文献稀少，但总体而言，它表明与食物相关的社交媒体、负面身体形象和饮食失调之间可能存在关联。需要更多的实验研究来阐明不同媒体类型（如美食博客与吃播视频）的结果，并确定每种媒体类型的因果关系方向。
