The placement of nutrition information on the front of food packages has been proposed as a method of providing simplified and visible nutrition information. This study aimed to determine the most acceptable and effective front-of-pack food labelling system for Australian consumers. Consumers' preferences and ability to compare the healthiness of mock food products were assessed for different front-of-pack labelling systems. Four systems were tested, including two variations of the Percentage Daily Intake system (Monochrome %DI and Colour-Coded %DI), which displays the proportion of daily nutrient contribution that a serve of food provides; and two variations of the Traffic Light (TL) system (Traffic Light and Traffic Light + Overall Rating), which uses colour-coding to indicate nutrient levels. Intercept surveys with 790 consumers were conducted, where each participant was exposed to a single labelling system for performance testing. Participants indicated strong support for the inclusion of nutrient information on total fat, saturated fat, sugar and sodium on the front of packages, and a consistent labelling format across all products. Using the TL system, participants were five times more likely to identify healthier foods compared with the Monochrome %DI system [odds ratio (OR) = 5.18; p < 0.001], and three times more likely compared with the Colour-Coded %DI system (OR = 3.01; p < 0.05). Consumers supported the introduction of consistent front-of-pack food labelling. The TL system was the most effective in assisting consumers to identify healthier foods. Mandatory TL labelling regulations are recommended to assist consumers in making healthy food choices.
在食品包装正面标注营养信息已被提议作为一种提供简化且直观的营养信息的方法。本研究旨在确定对澳大利亚消费者而言最可接受且有效的食品包装正面标签系统。针对不同的食品包装正面标签系统，评估了消费者对模拟食品的健康程度进行比较的偏好和能力。测试了四种系统，包括每日摄入量百分比系统的两种变体（单色%DI和彩色编码%DI），该系统显示一份食物所提供的每日营养贡献比例；以及交通信号灯（TL）系统的两种变体（交通信号灯和交通信号灯+总体评级），该系统使用颜色编码来指示营养水平。对790名消费者进行了拦截式调查，每位参与者都接触一种单一的标签系统以进行性能测试。参与者表示强烈支持在包装正面包含总脂肪、饱和脂肪、糖和钠的营养信息，以及所有产品采用一致的标签格式。与单色%DI系统相比，使用TL系统的参与者识别更健康食品的可能性高出五倍[优势比（OR）=5.18；p<0.001]，与彩色编码%DI系统相比高出三倍（OR=3.01；p<0.05）。消费者支持引入一致的食品包装正面标签。TL系统在帮助消费者识别更健康食品方面最为有效。建议实施强制性的TL标签法规，以帮助消费者做出健康的食品选择。
