近年来,在国家和欧盟(EU)一级做出了一致的政治努力,以促进健康食品的消费。欧盟委员会(EC)表示需要在欧盟一级建立统一和强制性的包装前营养标签(FOPL)系统。欧共体将在2022年底前通过该提案。我们的研究工作旨在通过Twitter了解欧盟公众对FOPL的讨论,通过分析推文内容,情绪,和映射网络特征。使用Twitter应用程序编程接口(API)执行Tweet搜索和数据收集,没有时间或语言限制。使用QRSNvivo软件包对内容进行编码并进行主题分析。使用QSRNvivo进行自动情绪分析,用Gephi0.9.2进行网络分析。总共发布了4,073条推文,大部分来自英国,西班牙,和法国。Twitter上讨论中出现的主题包括食品标签的类型,食品工业,健康vs.食品标签中的不健康食品,欧盟法规,政治冲突,科学和教育。Nutri-Score主导了Twitter上的讨论。Twitter用户对一般主题持负面看法,对食品行业持更积极的态度,而对政治冲突的话语则表现出负面情绪。网络分析表明,国家之间几乎不存在集中式通信。我们的结果表明,Twitter上对FOPL的讨论仅限于非常有限的人群,似乎有必要向广大消费者通报现有和即将推出的FOPL计划。教育计划应使消费者能够了解什么是健康饮食以及它与FOPL的关系。不管现有的标签系统。
In recent years, concerted political efforts have been made at the national and European Union (EU) level to promote the consumption of healthy foods. The European Commission (EC) expressed the need for a harmonized and mandatory front-of-pack nutrition labeling (FOPL) system at the EU level. The EC will adopt the proposal by the end of 2022. Our research work aims to understand the public discourse on FOPL in the EU via Twitter, by analyzing tweet content, sentiment, and mapping network characteristics. Tweet search and data collection were performed using the Twitter application programming interface (API), with no time or language restrictions. The content was coded with the QRS Nvivo software package and analyzed thematically. Automatic sentiment analysis was performed with QSR Nvivo, and network analysis was performed with Gephi 0.9.2. A total of 4,073 tweets were posted, mostly from the UK, Spain, and France. Themes that have emerged from the discussion on Twitter include the types of food labeling, food industry, healthy vs. unhealthy foods in the context of food labeling, EU regulation, political conflicts, and science and education. Nutri-Score dominated the discussion on Twitter. General topics were perceived negatively by Twitter users with more positive sentiments toward the food industry, while negative sentiments were observed toward the discourse of political conflicts. The network analysis showed that a centralized communication was hardly existed between countries. Our results reveal that the discussion of FOPL on Twitter is limited to a very limited group of people, and it seems necessary to inform a wide range of consumers about existing and upcoming FOPL schemes. Educational programs should empower consumers to understand what a healthy diet is and how it relates to FOPL, regardless of the existing labeling system.
