Nutrition when someone is pregnant or breastfeeding is vital in promoting motherhood and healthy growth and development of the baby. Adequate consumption of macronutrients, vitamins, minerals, and fluid is essential for normal fetal development, support for maternal energy needs, and improved milk quality during lactation. In this session, we’ll discuss dietary recommendations based in science, the timing of nutrients, and considerations for common conditions, such as gestational diabetes, anemia, and nutrient deficiencies. Participants will leave this session with practical resources to optimize maternal nutrition, promote healthy pregnancies, support breastfeeding, and lay the foundation for lifelong health in children.
