Abstract
The aim of this study is to elucidate the relationship between food purchasing behavior and the consumption of nutrients and various food groups. Our research focused on the influence of store format preferences on food purchasing behavior, using food purchase history data. We categorized consumers' store format choices into four clusters. However, our analysis noted no significant differences in nutrient or food group intake among the clusters. This finding challenges the prevailing notion that convenience stores and dining out are likely associated with unhealthy dietary patterns.
