Abstract The rapid economic and demographic transitions in Asia have reshaped dietary behaviors, with Food Away from Home (FAFH) becoming an increasingly central aspect of food consumption. This study synthesizes peer-reviewed evidence published between 2010 and 2024 to examine the determinants, health outcomes, and socio-economic implications of FAFH across selected Asian countries. Using the PRISMA framework, a total of 49 studies were systematically reviewed and categorized into six domains: demographic, economic, environmental, external, health, and societal drivers. Findings reveal that rising incomes, urbanization, dual-income households, and digitalization (particularly online food delivery) are principal drivers of FAFH growth, while cultural norms, food safety concerns, and inequality moderate these trends. Health evidence consistently links FAFH to elevated risks of obesity, diet-related non-communicable diseases, and excessive sodium intake, whereas socio-economic outcomes reflect both modernization and vulnerabilities in food self-sufficiency. The review underscores the need for policy strategies that integrate food safety regulations, nutritional education, fiscal incentives, and digital platform governance to mitigate risks while accommodating shifting consumer demand. This synthesis contributes to regional and cross-national understanding of FAFH in Asia, highlighting its dual role in fostering economic dynamism and exacerbating health and food security challenges.
