The ongoing pandemic of “hidden hunger”, characterized by excessive consumption of ultra-processed and nutrient-poor foods, is prevalent in Western countries, particularly among young individuals. While evidence on maternal nutrition predominantly focuses on low-income countries, emphasizing the detrimental effects of malnutrition on fetal growth, research examining the impact of “hidden hunger” on fetal development remains insufficient and lacks robustness to significantly influence medical decisions and interventions for young pregnant women. This Special Issue has the potential to significantly contribute to filling these existing gaps. It captures the diversity and complexity of research on nutritional impacts on maternal health, fetal development, and perinatal outcomes. The range of methodologies and subjects covered in these articles reflects the dynamic nature of this field. From predictive modeling to practical interventions, these studies significantly contribute to our understanding and management of maternal and fetal health. This compilation not only provides valuable insights into current research but also sets the stage for future investigations in this vital area of public health. More research is needed to explore personalized nutritional strategies grounded in contemporary scientific knowledge for enhancing maternal health and optimizing perinatal outcomes.
