Neonatal Care plays a key role in fetal growth and development. Maternal nutrition not only refers to the nutritional needs of women during the antenatal and postnatal period (i.e., when they are pregnant and breastfeeding) but also to the pre-conceptual period (i.e., adolescence). A healthy diet helps children to grow and learn. It also helps prevent obesity and other weight-related diseases, such as diabetes. Any kind of alterations in foetal nutrition or endocrine status may result in developmental adaptations that permanently change the structure, metabolism and physiology of the offspring, thereby predisposing individuals to metabolic, endocrine, and cardiovascular diseases in adult life.
