Optimizing Maternal Nutrition and its Impact on Fetal Development: Evidence-Based Insights and Current Guidelines

Maternal nutrition is critical in shaping fetal development and lifelong health outcomes. Both overnutrition and undernutrition during pregnancy significantly influence neonatal health, congenital anomalies, and long-term risks for metabolic and neurodevelopmental disorders. Maternal obesity increases the risks of complications such as congenital anomalies, macrosomia, and delivery injuries, while maternal undernutrition leads to intrauterine growth restriction (IUGR), low birth weight (LBW), and neonatal morbidity. This article provides evidence-based insights into the impact of maternal nutrition, reviews global guidelines, and explores targeted interventions to optimize maternal and fetal health. Figures and graphical representations highlight key concepts, making the discussion comprehensive and engaging.
