摘要

关于包装前标签(FoPL)系统在帮助选择符合特定营养要求的食品方面的有效性,还存在很大的知识差距。本研究试图比较营养分数(NS)标签和营养信息电池(NIB)标签在帮助消费者选择低钠或低饱和脂肪食品方面的有效性。利用对照实验设计,1512 名参与者(年龄在 18-70 岁之间,50.8% 为女性)通过计算机辅助网络访谈进行了情景体验,在这些情景中,他们选择了适合血压或血浆胆固醇水平不达标者食用的食品,这些食品分别贴有 NS、NIB 或无标签(盲标)。事实证明,在指导参与者选择更符合营养需求的食品以控制血压或胆固醇方面,NIB 明显比 NS 更有效。此外,参与者普遍对 NIB 更有好感,认为它更值得信赖、信息量更大、对所需任务更有用。值得注意的是,年轻的参与者、营养知识水平较高的参与者以及不那么倾向于直觉或自发决策的参与者在使用 NIB 时更倾向于做出符合健康的食物选择。研究结果表明,信息丰富的 FoPL 系统 NIB 在满足特定饮食要求方面可能具有更大的优势。这强调了食品标签系统在促进公众健康、满足消费者多样化和特定需求方面的重要作用。要在更广泛的背景下和针对更多的健康状况确认这些结果,还需要进一步的研究。

The role of Nutri-Score and NutrInform Battery in guiding the food choices of consumers with specific nutritional needs: A controlled study

Background and aims

There is a significant knowledge gap regarding the effectiveness of front-of-pack labeling (FoPL) systems in helping food choices that meet specific nutritional requirements. This study sought to compare the effectiveness of the Nutri-Score (NS) and NutrInform Battery (NIB) labels in assisting consumers to select food products with low sodium or low saturated fat.

Methods and results

Utilizing a controlled experimental design, a sample of 1512 participants (aged 18–70, 50.8% females) was exposed to scenarios through computer-assisted web interviewing, where they selected food products suitable for people with suboptimal blood pressure or plasma cholesterol levels, labeled with either NS, NIB, or no label (blind). The NIB proved significantly more efficacious than NS in guiding participants towards making selections in better agreement with nutritional needs, for blood pressure or cholesterol control. Furthermore, the NIB was generally viewed more favorably, with participants rating it as more trustworthy, informative, and useful for the required task. Notably, younger participants, those with higher nutritional knowledge, and those less inclined towards intuitive or spontaneous decision-making demonstrated a greater propensity for making health-congruent food choices when using the NIB.

Conclusion

The findings suggest that the informative FoPL system, NIB, may offer greater advantages in addressing specific dietary requirements. This underscores the important role of FoPL systems in promoting public health and meeting diverse and specific consumer needs. Further research is needed to confirm these results in broader contexts and for additional health conditions.

期刊介绍: Nutrition, Metabolism & Cardiovascular Diseases is a forum designed to focus on the powerful interplay between nutritional and metabolic alterations, and cardiovascular disorders. It aims to be a highly qualified tool to help refine strategies against the nutrition-related epidemics of metabolic and cardiovascular diseases. By presenting original clinical and experimental findings, it introduces readers and authors into a rapidly developing area of clinical and preventive medicine, including also vascular biology. Of particular concern are the origins, the mechanisms and the means to prevent and control diabetes, atherosclerosis, hypertension, and other nutrition-related diseases.
