食品包装正面营养标签是位于食品包装正面的简明标签，提供截断的营养信息。这些标签正在迅速获得世界范围内的突出地位，大概是因为他们吸引了注意力，其简化的格式，使快速比较的营养价值methodsEye跟踪进行了美国消费者与实际的包装与无FOP标签（1）评估是否存在的FOP标签增加注意力的营养信息时，观众没有专门负责与营养相关的目标;和（2）研究FOP的存在对消费者使用更全面的，传统的营养信息的营养成分面板（NFP），在美国的大多数包装食品的强制性标签的影响。ResultsOur结果表明，彩色FOP标签提高了任何营养信息出席的概率，并导致更快的检测和更长的时间查看营养信息。然而，对于谷物包装，这些好处是以牺牲对更全面的NFP的关注为代价的。我们的研究结果与FOP标签的潜在捷径效应一致，如果存在FOP，参与者花更少的时间参加更全面的NFP。对于饼干，FOP标签增加了时间花在参加营养信息，但我们没有发现任何证据表明，他们的存在减少了时间花在NFP.ConclusionsThe的营养信息的人没有明确的营养目标的人，FOP标签增加了对整体营养信息的关注表明，这些标签可能具有优势，在传达营养信息，以广泛的人群。然而，对于某些食物类型，这种好处可能会带来捷径效应;也就是说，减少对更全面的营养信息的关注。这些结果对政策有影响，并需要进一步研究FOP标签影响消费者对不同食品的营养信息使用的机制。
BackgroundFront of pack (FOP) nutrition labels are concise labels located on the front of food packages that provide truncated nutrition information. These labels are rapidly gaining prominence worldwide, presumably because they attract attention and their simplified formats enable rapid comparisons of nutritional value.MethodsEye tracking was conducted as US consumers interacted with actual packages with and without FOP labels to (1) assess if the presence of an FOP label increases attention to nutrition information when viewers are not specifically tasked with nutrition-related goals; and (2) study the effect of FOP presence on consumer use of more comprehensive, traditional nutrition information presented in the Nutritional Facts Panel (NFP), a mandatory label for most packaged foods in the US.ResultsOur results indicate that colored FOP labels enhanced the probability that any nutrition information was attended, and resulted in faster detection and longer viewing of nutrition information. However, for cereal packages, these benefits were at the expense of attention to the more comprehensive NFP. Our results are consistent with a potential short cut effect of FOP labels, such that if an FOP was present, participants spent less time attending the more comprehensive NFP. For crackers, FOP labels increased time spent attending to nutrition information, but we found no evidence that their presence reduced the time spent on the nutrition information in the NFP.ConclusionsThe finding that FOP labels increased attention to overall nutrition information by people who did not have an explicit nutritional goal suggests that these labels may have an advantage in conveying nutrition information to a wide segment of the population. However, for some food types this benefit may come with a short-cut effect; that is, decreased attention to more comprehensive nutrition information. These results have implications for policy and warrant further research into the mechanisms by which FOP labels impact use of nutrition information by consumers for different foods.
