This study is a systematic review of reviews conducted between 2017 and 2021, aiming to provide an updated understanding of consumer food choice and identify knowledge gaps. The review synthesizes findings from multiple studies using a socioecological model, integrating four levels of social and environmental systems: the physical food environment, the social and community level, interpersonal relations, and individual characteristics. Key factors influencing food choice include product attributes, available information, price, context, personal and group influences, and sensory perceptions. The analysis highlights that behavioral patterns, influenced by strong informal institutions like culture and norms, can be challenging to change, particularly towards more sustainable food behaviors. The findings suggest a need for more interdisciplinary research and real-life studies to better understand the complexity of food choice, emphasizing the role of the physical environment, social interactions, and culture in shaping consumer decisions.This study is a systematic review of reviews conducted between 2017 and 2021, aiming to provide an updated understanding of consumer food choice and identify knowledge gaps.
