Food choices and dietary behaviours are shaped by a complex interplay of personal preferences, social influences, cultural norms, and environmental factors such as affordability and access. Food environments—homes, schools, and workplaces—along with broader food systems, further influence how and what people eat. Cultural traditions, socioeconomic status, and modern pressures like fast-food culture and the nutrition transition continue to reshape dietary patterns and health outcomes. Addressing these challenges requires culturally informed, context-specific approaches that promote sustainable and healthier behaviours.
