Visual Nudging: The Effectiveness of Front-of-Pack Nutrition Labeling on Food Products in the Czech Republic

The bachelor's thesis focuses on evaluating the effectiveness of Nutri-Score nutrition labeling as a visual nudging tool in the context of the Czech market. Its aim is to verify whether the Nutri-Score system influences consumer decision-making in favor of healthier food choices and whether its effectiveness varies depending on consumers' sociodemographic characteristics. Respondents' decision-making was analyzed based on their choices between two categories of food products (breakfast cereals and frozen pizza), which were first presented without any labeling and then with the Nutri-Score system. Based on the collected data, variables were created to capture possible changes in choice within both categories. Subsequently, six models using logistic regression were constructed. Four of these models focused on verifying the effect of the labeling itself, while the remaining two also took into account the respondents' sociodemographic characteristics. The results showed that Nutri-Score significantly reduces the likelihood of a change in choice toward products with lower nutritional value in both categories. However, it was not confirmed that the effectiveness of the system differs statistically significantly across individual sociodemographic groups.
