Using propensity score matching(PSM) techniques, this study analyzes differences in food purchase and consumption behaviors according to dietary attitudes. Individuals' dietary attitudes are defined as eating breakfast, eating a balanced diet, eating with family, eating alone, and eating rice-based meals. The analysis results of this study show that there are differences in food purchase and consumption behaviors (frequency of online food purchases, frequency of using early morning delivery, frequency of eco-friendly food purchases, consumption of health functional foods, purchase of domestic and local food ingredients, and frequency of home meal replacement purchases) according to dietary attitudes. Furthermore, this study extends the analysis by relating the findings to dietary change trends and provides a consolidated outlook on future food consumption.
