The public is increasingly looking for healthier alternatives in food products. Front-of-pack labelling aims to help consumers make healthier food choices. The aim of our study was to investigate whether Nutri-Score can improve nutritional choices of Polish consumers. The survey was conducted using the CAWI method. The proprietary questionnaire included metric questions, knowledge about the Nutri-Score system and questions on nutritional knowledge from the KomPAN questionnaire. To assess the effectiveness of the Nutri-Score system, participants compared healthiness of 8 product pairs with visible and invisible Nutri-Score labelling. The study involved 1035 participants, a representative sample of the Polish population. Participants had average nutritional knowledge (5.6 ± 2.14 out of 10 points) and average knowledge of Nutri-Score (2.9 ± 1.66 out of 7 points). The results showed that visibility of the system did not significantly (p > 0.05) influence consumers' dietary choices. An unfavourable dietary change was shown (p < 0.001) for two pairs of products: fish (OR of 11.56 (95% CI [8.40-15.91]) and ham OR of 2.84 (95% CI [2.19-3.69]). The distribution of the data obtained indicated a negative effect of the system on consumer choices. In conclusion, our study showed that the Nutri-Score system has a limited effect on improving health-promoting dietary choices.
公众越来越多地在食品中寻找更健康的替代品。包装正面标签旨在帮助消费者做出更健康的食品选择。我们研究的目的是调查营养评分是否能改善波兰消费者的营养选择。该调查采用了计算机辅助网络访谈（CAWI）方法。专有问卷包括计量问题、关于营养评分系统的知识以及来自KomPAN问卷的营养知识问题。为了评估营养评分系统的有效性，参与者比较了8组带有可见和不可见营养评分标签的产品对的健康程度。该研究涉及1035名参与者，这是波兰人口的一个代表性样本。参与者的营养知识水平平均（满分10分，得5.6±2.14分），对营养评分的了解程度平均（满分7分，得2.9±1.66分）。结果表明，该系统的可见性对消费者的饮食选择没有显著影响（p>0.05）。对于两组产品显示出不利的饮食变化（p<0.001）：鱼类（优势比为11.56（95%置信区间[8.40 - 15.91]））和火腿（优势比为2.84（95%置信区间[2.19 - 3.69]））。所获得数据的分布表明该系统对消费者选择有负面影响。总之，我们的研究表明营养评分系统在改善促进健康的饮食选择方面效果有限。
