Traffic light labelling (TLL) policy has been adopted to improve consumers' food choices. This qualitative study examined the consumers' perception of TLL and nutritional facts table (NFT) in Iran.
We applied a qualitative method to explore public views and perceptions of NFT and TLL in Iran. Participants ageing 20-75 years old were selected by maximum diversity sampling and interviewed using a semi-structured in-depth interview. The interviews were continued until data saturation was achieved after interviewing 35 participants with five more interviews to ensure no new emerging perception. Data was analysed by directed content analysis in MAXQDA 10 software.
Findings indicated that a large number of the participants were not aware of NFT and TLL. There are some reasons for not paying attention to NFT and TLL, which include lack of enough knowledge about NFT and TLL concepts and defects in appearance and details written in these labels, lack of appropriate education about labels, place of putting the labels and lack of enough time for using the labels during shopping.
It is concluded that educational interventions should be applied to ensure their effectiveness in improving healthy food choices.
信号灯标签（TLL）政策已被采纳，以改善消费者的食物选择。本定性研究旨在探讨伊朗消费者对 TLL 和营养事实表（NFT）的看法。
我们采用定性方法来探索伊朗公众对 NFT 和 TLL 的看法和看法。通过最大差异抽样选择年龄在 20-75 岁的参与者，并通过半结构化深入访谈进行采访。在对 35 名参与者进行访谈后，继续进行访谈，直到达到数据饱和，之后又进行了 5 次访谈，以确保没有新的观点出现。使用 MAXQDA 10 软件进行定向内容分析。
研究结果表明，许多参与者不知道 NFT 和 TLL。不关注 NFT 和 TLL 的原因有很多，包括对 NFT 和 TLL 概念缺乏足够的了解，以及这些标签外观和书写细节上的缺陷，对标签缺乏适当的教育，标签的放置位置以及购物时没有足够的时间使用标签。
研究结论认为，应采取教育干预措施，以确保其在改善健康食品选择方面的有效性。
