Maternal nutrition refers to the dietary needs and intake of nutrients by pregnant women and nursing mothers. Proper nutrition during pregnancy is crucial for the health and development of both the mother and the unborn baby. Maternal nutrition can impact the growth and development of the fetus, as well as the long-term health outcomes of the child. Research in this area focuses on understanding the specific nutrient requirements during pregnancy and lactation, as well as the effects of maternal diet on pregnancy outcomes, birth weight, and breastfeeding success. It also includes studying the impact of maternal nutrition on the risk of developing conditions such as gestational diabetes, preeclampsia, and obesity. Overall, research in maternal nutrition aims to optimize maternal health and well-being, as well as the health of the next generation.
