This thesis examined consumer behavior toward food labels in Hungary and the United States, focusing on how demographic, socioeconomic, and lifestyle factors influence engagement with nutrition labels within each country, factors that motivate or discourage engagement with nutrition labels, and differences in country responses to various FOPLs (Traffic Light, Warning labels, and Nutri-Score). A substantial portion of respondents claim to actively engage with nutrition labels to a certain extent. Demographic and socioeconomic variables such as income, age, and education did not significantly predict label use, instead, lifestyle factors, such as behaviors, confidence, and attitudes toward healthy eating, played a more significant role. Nutritional information and ingredients were surpassed by price and taste, remaining the most influential factors across both countries, indicating that certain external factors have greater influence on purchase decisions than nutritional value. When comparing different front-of-pack label formats, TLS consistently emerged as the most supported option but NS and WLs proved to be more effective in influencing purchasing intentions. No significance was found between countries and how they responded to the given FOPLs, suggesting that, regardless of differences between countries, labeling systems are still perceived similarly. Overall, the findings suggest that interpretive labels, like NS or TLS, can guide healthier purchases across countries and provide valuable insights for global labeling policies.
