As standards are considered for nutrition front-of-package (FOP) and shelf-labeling systems in the United States, it is important to know what types of systems are most effective in conveying scientifically accurate and useful information to consumers. A systematic literature review identified 38 empirical studies on consumer response to FOP nutrition labeling and shelf labeling. Studies indicate that consumers can more easily interpret and select healthier products with nutrient-specific FOP nutrition labels that incorporate text and symbolic color to indicate nutrient levels rather than nutrient-specific labels that only emphasize numeric information, such as Guideline Daily Amounts expressed as percentages and/or grams. Summary systems may influence consumers to purchase healthier products. However, more research is needed to assess the influence of nutrient-specific labels on consumers' purchases. This review identified few studies that compared consumers' ability to select healthier products using nutrient-specific systems that incorporate text and color codes with multiple-level summary icons. More research is needed to determine the effects of FOP nutrition labeling on consumers' actual shopping behaviors and dietary intakes.
在美国制定营养前置（FOP）和货架标签系统标准时，了解哪些类型的系统在向消费者传达科学准确和有用的信息方面最有效非常重要。一项系统文献综述确定了 38 项关于消费者对 FOP 营养标签和货架标签反应的实证研究。研究表明，消费者可以更容易地解释和选择更健康的产品，这些产品具有特定于营养素的 FOP 营养标签，其中包含文本和符号颜色来表示营养素水平，而不是仅强调数字信息的特定于营养素的标签，例如以百分比和/或克表示的每日摄入量指南。摘要系统可能会影响消费者购买更健康的产品。但是，需要进行更多的研究来评估特定于营养素的标签对消费者购买的影响。本综述发现，很少有研究比较消费者使用特定于营养素的系统选择更健康产品的能力，这些系统结合了文本和颜色代码以及多层次的摘要图标。需要进行更多的研究来确定 FOP 营养标签对消费者实际购物行为和饮食摄入的影响。
