The effect of the nutri-score label on consumer's attitudes, taste perception and purchase intention: An experimental pilot study

A large number of studies has emerged on the environmental impacts of diets, with most studies concluding that a diet rich in plant-based foods, that are low in salt, sugar, and fat, and score high in nutritional values, confers both improved health and environmental benefits. Currently, new interventions are being implemented to improve people's eating behavior, because most people overconsume unhealthy snacks, containing high proportions of salt, sugar and fat. The purpose of the current pilot study was to investigate the effects of the NutriScore label on three different snack bars on consumers' attitudes, taste perception, and purchase intention towards these food products. An experimental study was conducted with a between subject design (food packaging with Nutri-Score label versus without) among 192 participants (Mage 31.7 years, SD 14.3 years; 63% female). Results showed that there were no effects found for the effect of the Nutri- Score label on consumers' attitudes, taste perception and purchase intention. Bayesian analyses support the conclusion that the null hypothesis is accepted. These findings show that integrating the Nutri-Score label on food packages did not modify cognitive responses of consumers towards these food products. Changing consumption behaviors is challenging and more empirical and theoretical understanding is needed.

Automated summary

Results from an experimental study examining the effects of Nutri-Score label on snack bars showed that it did not have an impact on consumers' attitudes, taste perception, and purchase intentions. This suggests that integrating Nutri-Score label on food packaging may not lead to changes in consumers' cognitive responses towards the products, indicating that changing consumption behaviors is challenging and requires further empirical and theoretical understanding.
