This chapter analyzes eating behavior and its impact on the health of migrant populations, focusing on Latin America. It explores how factors such as acculturation stress, ethnic identity, and food insecurity influence the eating habits and mental health of migrants. The migration process affects individuals’ relationships with food, often resulting in unhealthy eating patterns that lead to malnutrition and chronic diseases. The concept of food acculturation is examined, reflecting how migrants balance the dietary practices of their home countries with those of the host country. This process can manifest in the adoption of diets high in ultra-processed foods, exacerbating health issues like obesity and diabetes. The chapter also emphasizes the importance of developing inclusive food policies that are culturally adapted to migrants’ needs, as well as improving the nutritional care systems for this population. In conclusion, the chapter highlights the need for interventions that promote healthy eating and consider both psychological and cultural factors to improve public health in migratory contexts.
