To determine how frequently lay consumers evaluate both the front label of a product package and other nutritional information on the back label of the package; whether the nutritional descriptors on the front label that concern fat affect consumer choice; to what degree information on the back label redirects this choice; and how well consumers understand the percent daily value on the new food label.
Preliminary cross-sectional survey.
General community and university setting.
Volunteer sample of 200 men and women.
METHODS/RESULTS: Participants were first asked to choose between two fabricated cookie packages, one with a "low fat" and the other with a "no saturated fat" front label. Eighty-four percent of participants made their product choice without turning the package to view the back label. Thirty-six percent chose the product with the low fat front label, while 64% chose the product with the no saturated fat front label. In contrast, when respondents were subsequently presented with two cake products that contained no front-label descriptors (which resulted in 100% of subjects turning the package to view the back label), 53% chose the product with a label indicating 6 g of total fat (none saturated), while 47% chose the product with a label indicating 4 g of total fat (all saturated). Thirty-two of the 94 respondents who chose the no saturated fat cookie (only viewing the front label and giving fat content as the reason for their choice) chose a cake product in which the fat was all saturated, based on back-label nutrition information. Finally, 56% of participants could not accurately use the new percent daily value component to calculate saturated fat content.
The data from this pilot study suggest that consumers make product choices based on only viewing the front-label information; health claims on the front label that are related to fat do affect product choice; a choice made based on the information on the front label is potentially altered once the back label is viewed; and approximately one half of our population could not clearly understand the percent daily value. We conclude that current consumer choice may be overly influenced by industry-directed claims placed on the front of a product package.
确定普通消费者评估产品包装正面标签及包装背面其他营养信息的频率;正面标签上有关脂肪的营养描述是否会影响消费者选择;背面标签信息在多大程度上改变了这一选择;以及消费者对新食品标签上每日营养素参考值的理解程度。
初步横断面调查。
普通社区和大学环境。
200名男女志愿者样本。
方法/结果:首先要求参与者在两个虚构的饼干包装中进行选择,一个正面标签为“低脂”,另一个为“无饱和脂肪”。84%的参与者在不翻转包装查看背面标签的情况下做出了产品选择。36%的人选择了正面标签为低脂的产品,而64%的人选择了正面标签为无饱和脂肪的产品。相比之下,当随后向受访者展示两种没有正面标签描述的蛋糕产品时(这导致100%的受试者翻转包装查看背面标签),53%的人选择了标签显示总脂肪含量为6克(无饱和脂肪)的产品,而47%的人选择了标签显示总脂肪含量为4克(全是饱和脂肪)的产品。在仅查看正面标签并以脂肪含量作为选择理由而选择无饱和脂肪饼干的94名受访者中,有32人根据背面标签的营养信息选择了一种脂肪全是饱和脂肪的蛋糕产品。最后,56%的参与者无法准确使用新的每日营养素参考值成分来计算饱和脂肪含量。
这项初步研究的数据表明,消费者仅根据正面标签信息做出产品选择;正面标签上与脂肪相关的健康声明确实会影响产品选择;一旦查看背面标签,基于正面标签信息做出的选择可能会改变;而且我们大约一半的人群无法清楚理解每日营养素参考值。我们得出结论,当前消费者的选择可能受到产品包装正面行业导向声明的过度影响。
