Nutrition labels on prepackaged foods have been widely advocated as a medium to foster healthier eating habits in the general population.
The study is aimed at understanding how people value nutritional information on food labels, in particular for front-of-pack labeling.
A phone-assisted survey of 7550 consumers in 16 European countries was conducted. People were asked about their opinion on nutritional information provided at different levels, from the media to public institutions, and their commitment to healthy behavior. The value of pack labeling was estimated using a willingness-to-pay (WTP) elicitation technique.
Older age groups (>45 years old), members of a larger family, people of low income or low education, and those who perceived themselves to be obese valued front-of-pack nutritional labeling. WTP estimates across all countries provided an average accepted added price of $4.32 to the overall yearly food expenditure (95% confidence interval, 3.33-3.68).
Overall, perceived value of labeling is low. However, factors affecting the value for consumer of nutritional labeling appear to be strictly linked to the socioeconomic and health status of the respondents.
预包装食品上的营养标签已被广泛倡导为一种在普通人群中培养更健康饮食习惯的媒介。
本研究旨在了解人们如何重视食品标签上的营养信息，特别是包装正面标签。
对16个欧洲国家的7550名消费者进行了电话辅助调查。询问了人们对从媒体到公共机构在不同层面提供的营养信息的看法，以及他们对健康行为的承诺。使用支付意愿（WTP）诱导技术估计包装标签的价值。
年龄较大的群体（>45岁）、大家庭成员、低收入或低教育水平的人以及那些认为自己肥胖的人重视包装正面营养标签。所有国家的WTP估计表明，相对于全年食品总支出，平均可接受的额外价格为4.32美元（95%置信区间，3.33 - 3.68）。
总体而言，标签的感知价值较低。然而，影响消费者对营养标签价值的因素似乎与受访者的社会经济和健康状况密切相关。
