包装正面的营养标志（FOPs）可能很容易被注意到，并且只需要很少的营养知识就可以使用。尽管有证据支持这一观点，但很少有研究关注美国使用的事实前置类型符号。具有不同程度先验知识的参与者被要求观看两种产品，并决定哪一种更健康。包装上的FOPs被操纵，使一种产品更健康，使我们能够评估准确性。通过眼动追踪来评估对营养信息的关注，以确定是否有任何FOP信息被用于做出决定。结果显示，尽管咨询了FOPs，但有一半的比较准确性低于机会。对卡路里、脂肪和钠的关注与准确性之间的负相关表明，消费者过度依赖这些营养素。虽然对纤维和糖的关注相对较少，但注意力和准确性之间的关系是积极的。对维生素D的关注没有显示出与准确性的关联，这表明人们对不同产品中什么构成有意义的变化感到困惑。更多的营养知识与更高的准确性相关，即使是在较少关注的情况下。个人，特别是那些知识较少的人，会被食物上的卡路里、钠和脂肪信息所误导。
Front-of-package nutrition symbols (FOPs) are presumably readily noticeable and require minimal prior nutrition knowledge to use. Although there is evidence to support this notion, few studies have focused on Facts Up Front type symbols which are used in the US. Participants with varying levels of prior knowledge were asked to view two products and decide which was more healthful. FOPs on packages were manipulated so that one product was more healthful, allowing us to assess accuracy. Attention to nutrition information was assessed via eye tracking to determine what if any FOP information was used to make their decisions. Results showed that accuracy was below chance on half of the comparisons despite consulting FOPs. Negative correlations between attention to calories, fat, and sodium and accuracy indicated that consumers over-relied on these nutrients. Although relatively little attention was allocated to fiber and sugar, associations between attention and accuracy were positive. Attention to vitamin D showed no association to accuracy, indicating confusion surrounding what constitutes a meaningful change across products. Greater nutrition knowledge was associated with greater accuracy, even when less attention was paid. Individuals, particularly those with less knowledge, are misled by calorie, sodium, and fat information on FOPs.
