The rapid adoption and sustained use of social media globally has provided researchers with access to unprecedented quantities of low-latency data at minimal costs. This may be of particular interest to nutrition research because food is frequently posted about and discussed on social media platforms. This scoping review investigates the ways in which social media is being used to understand population food consumption, attitudes and behaviours.
The peer-reviewed literature was searched from 2003 to 2021 using four electronic databases.
The review identified 71 eligible studies from 25 countries. Two-thirds (n = 47) were published within the last 5 years. The USA had the highest research output (31%, n = 22) and Twitter was the most used platform (41%, n = 29). A diverse range of dataset sizes were used, with some studies relying on manual techniques to collect and analyse data, whereas others required the use of advanced software technology. Most studies were conducted by disciplines outside health, with only two studies (3%) being conducted by nutritionists.
It appears the development of methodological and ethical frameworks as well as partnerships between experts in nutrition and information technology may be required to advance the field in nutrition research. Moving beyond traditional methods of dietary data collection may prove social media as a useful adjunct to inform recommended dietary practices and food policies.
社交媒体在全球范围内的迅速采用和持续使用，为研究人员提供了以最小成本获取前所未有的大量低延迟数据的机会。这对于营养研究可能特别有意义，因为食物经常在社交媒体平台上被发布和讨论。本范围综述调查了社交媒体被用于了解人群食物消费、态度和行为的方式。
使用四个电子数据库，从 2003 年到 2021 年对同行评审文献进行了搜索。
综述从 25 个国家确定了 71 项符合条件的研究。三分之二（n=47）发表于过去 5 年。美国的研究产出最高（31%，n=22），Twitter 是使用最多的平台（41%，n=29）。使用了各种大小的数据集，有些研究依赖于手动技术来收集和分析数据，而另一些则需要使用先进的软件技术。大多数研究是由健康领域以外的学科进行的，只有两项研究（3%）是由营养师进行的。
似乎需要制定方法学和伦理框架，并在营养和信息技术专家之间建立伙伴关系，以推进营养研究领域的发展。除了传统的饮食数据收集方法之外，社交媒体可能被证明是一种有用的补充，可用于告知推荐的饮食实践和食品政策。
