基于对英国三大零售商的店内观察、店内访谈(2019年)和在家填写并返回的问卷(921)，调查了食品标签上营养信息的使用及其理解。受访者的营养知识也被测量，使用一种全面的工具，涵盖专家建议的知识，不同食品中的营养成分，以及不同食品中的卡路里含量。在六个产品类别中，27%的购物者被发现曾查看标签上的营养信息，参考的主要来源是指南每日数量(GDA)标签和营养网格/表格。受访者对主要包装前营养标签的理解是通过涉及概念理解、实质理解和健康推论的各种任务来衡量的，高达87.5%的受访者能够在一组三种不同的理解水平和使用水平之间通过不同的因果机制解释最健康的产品。回归分析显示，使用情况主要与对健康饮食的兴趣有关，而对食品标签上的营养信息的了解主要与营养知识有关。两者反过来都受到人口统计变量的影响，但影响方式不同。(C)2010爱思唯尔有限公司保留所有权利。
Based on in-store observations in three major UK retailers, in-store interviews (2019) and questionnaires filled out at home and returned (921), use of nutrition information on food labels and its understanding were investigated. Respondents' nutrition knowledge was also measured, using a comprehensive instrument covering knowledge of expert recommendations, nutrient content in different food products, and calorie content in different food products. Across six product categories, 27% of shoppers were found to have looked at nutrition information on the label, with guideline daily amount (GDA) labels and the nutrition grid/table as the main sources consulted Respondents' understanding of major front-of-pack nutrition labels was measured using a variety of tasks dealing with conceptual understanding, substantial understanding and health inferences Understanding was high, with up to 87.5% of respondents being able to identify the healthiest product in a set of three Differences between level of understanding and level of usage are explained by different causal mechanisms. Regression analysis showed that usage is mainly related to interest in healthy eating, whereas understanding of nutrition information on food labels is mainly related to nutrition knowledge. Both are in turn affected by demographic variables, but in different ways. (C) 2010 Elsevier Ltd All rights reserved.
