Seafood, a major source of essential protein for human nutrition, has gained increasing significance as consumption rises due to higher income levels, growing health awareness, and environmental concerns. This study investigates the effects of individual lifestyles, food consumption tendencies, and food safety concerns on seafood consumption behavior. Utilizing data from the 2022 Food Consumption Behavior Survey conducted by the Korea Rural Economic Institute, the analysis categorizes consumers by age group to account for the nonlinear relationship between age and seafood consumption. Key variables include seafood purchase frequency, demographic characteristics, food safety concerns, and dietary preferences. The results reveal that seafood consumption patterns vary significantly across age groups, highlighting the importance of age-specific marketing strategies. Moreover, the findings suggest a need to expand and strengthen the promotion of food safety certification systems and to develop more targeted promotional strategies that reflect the diverse characteristics of individual consumers.
