食品标签上提供的营养和健康信息越来越多，作为一个行业和法规的答案，消费者越来越关注饮食与健康的关系。先前的研究表明，消费者重视食品标签上的这些信息;然而，仍然没有明确的模式，即哪些标签选项更受重视，以及不同的消费者如何评价不同的选项。本文分析了一个选择实验的结果，以确定多种健康和营养信息来源对消费者食品选择的影响，考虑到偏好异质性，使用潜在的类的方法。结果表明，不同的消费群体可以明确区分的价值和行为模式。少数消费者重视高支付意愿（WTP）在营养事实小组提供额外的信息，但是，这并没有显示为绝大多数谁的价值索赔。此外，不考虑这种偏好异质性可能导致政策无法最大化消费者福利。根据每个群体中确定的消费者的特点，就行业和公共行政部门如何推动制定营养标签准则或政策提出了建议。
The provision of nutrition and health information on food labels is increasing as an industry and regulation answer to the growing consumer concern with diet-health relationships. Prior research has shown that the presence of this information on food labels is valued by consumers; however, there is still no clear pattern on which labelling options are more valued and how different consumers value the different options. This paper analyses the results of a choice experiment conducted to identify the effect of multiple health and nutrition information sources on consumer food choice, taking into account preference heterogeneity using a latent class approach. Results show that different consumer groups can be identified with clearly distinguishable valuation and behavioural patterns. A minority of consumers attaches high willingness to pay (WTP) to the provision of additional information in the nutrition facts panel, however, this is not shown for a vast majority who value claims. Moreover, not taking into account this preference heterogeneity can lead to policies that do not maximise consumer welfare. Based on the characteristics of consumers identified in each group, recommendations are made as to how both industry and public administration can move forward with the development of nutritional labelling guidelines or policies.
