Recent research reveals a significant advancement in promoting healthier dietary choices among Japanese college students through Traffic Light Food (TLF) labelling. This innovative approach, tested in a randomised controlled trial (RCT), demonstrates the potential for broader implementation nationwide to encourage health-conscious consumer behaviours. The study’s findings underscore the efficacy of TLF labelling in influencing dietary decisions, presenting valuable insights for exporters aiming to align with global health trends.

Traffic Light Food Labelling: An Effective Tool for Healthier Choices
The implementation of Traffic Light Food (TLF) labelling in Japan has shown promising results in guiding healthier dietary choices among consumers. This trend is driven by an increasing awareness of health and nutrition, coupled with regulatory efforts to combat lifestyle-related diseases through better food labelling practices.
In a recent RCT conducted between April 11 and May 2, 2022, involving 69 Japanese college students, researchers found that TLF labelling significantly influenced the participants' food choices. The intervention group, exposed to TLF-labelled food images, exhibited a marked preference for healthier options, reflected in a 20.6% increase in blue label (healthier) choices and a 12.6% decrease in red label (less healthy) choices by the end of the trial. These changes were statistically significant compared to the non-intervention group, which showed only a 10.5% higher preference for blue labels and a 13.3% lower preference for red labels.
Moreover, the study highlighted a 40% increase in nutritional awareness among the intervention group. Participants in this group were more conscious of their dietary balance and specific nutritional components, such as proteins, salt, and total fat, despite these not being explicitly labelled. This heightened awareness did not lead to increased psychological stress, indicating that TLF labelling can promote healthier choices without negatively impacting the consumer’s mental well-being.
The success of this labelling system in Japan mirrors global trends where front-of-pack (FOP) nutrition labels are used to prevent lifestyle-related diseases. By adapting the labelling to reflect cultural contexts—using blue instead of green to signify 'go'—the researchers ensured the labels resonated with local perceptions, enhancing their effectiveness. The study concludes that TLF labelling not only increases health awareness but also encourages healthier dietary habits, suggesting that policymakers should consider its broader implementation for public health strategies.
Strategic Actions
Implement Comprehensive Traffic Light Food Labelling
To capitalise on the positive outcomes of the TLF labelling system, businesses and policymakers should consider implementing comprehensive TLF labelling on food packaging. This strategy aims to guide consumers towards healthier choices and foster greater nutritional awareness.
Steps for Implementation:
Develop and Standardise Labels: Create standardised TLF labels tailored to the local cultural context, ensuring they adhere to internationally recognised nutritional standards. This involves extensive research and collaboration with nutrition experts to accurately categorise foods based on their health impacts.
Conduct Pilot Programs: Initiate pilot programs in selected regions or demographic groups to assess the effectiveness of TLF labelling. Collect and analyse data on consumer choices and health outcomes to refine the labelling system.
Engage Stakeholders: Work with food manufacturers, retailers, and health organisations to promote the adoption of TLF labels. Provide incentives and support to businesses that implement these labels, highlighting the potential benefits for consumer health and brand reputation.
Raise Public Awareness: Launch educational campaigns to inform consumers about the meaning of TLF labels and how to use them for making healthier dietary choices. Utilize various media channels to reach a broad audience, ensuring that the information is accessible and engaging.
Why: The adoption of TLF labelling is supported by empirical evidence demonstrating its effectiveness in promoting healthier dietary choices without causing psychological stress. This approach aligns with global health initiatives aimed at reducing lifestyle-related diseases through improved nutrition. By providing clear and easily understandable information, TLF labels empower consumers to make informed decisions, contributing to better public health outcomes.
Benefits: Implementing TLF labelling is expected to lead to a sustained increase in healthy food choices among consumers, thereby reducing the incidence of lifestyle-related diseases. This shift towards healthier eating habits can also enhance consumer loyalty and trust in brands that prioritise nutritional transparency. Additionally, businesses that adopt TLF labelling may gain a competitive edge by appealing to health-conscious consumers, ultimately driving sales and market share growth.
Case Study: The successful implementation of TLF labelling in Japan serves as a compelling case study for its broader application. The trial's results indicate significant improvements in dietary choices and nutritional awareness among participants, providing a robust foundation for advocating the widespread adoption of this labelling system in other regions and demographics.
