Nutrition During Pregnancy and Lactation

The National Academies of Sciences, Engineering, and Medicine last reviewed the state of the science on nutrition during pregnancy and lactation 30 years ago. The resulting consensus study reports from the Institute of Medicine—Nutrition During Pregnancy (IOM, 1990) and Nutrition During Lactation (IOM, 1991)—summarized the scientific evidence and provided nutrient recommendations. In the decades since the release of these two reports, the body of evidence on the relationships between nutrition during pregnancy and lactation and maternal and infant health and chronic disease has continued to grow and evolve. At the same time, the demographics of the population have shifted, giving rise to new considerations. To explore the evidence that has emerged, the National Academies conducted a 2-day workshop in January 2020. This publication summarizes the presentations and discussions from the workshop.Table of ContentsFront Matter1 Introduction2 Macronutrient Requirements3 One-Carbon Metabolism Micronutrients4 Iron, Vitamin D, Calcium, Antioxidants, and Iodine5 Dietary Supplements6 New Developments and Emerging Topics7 Maternal Intakes and Nutritional Status During Lactation and the Implications for Maternal and Infant Health8 Maternal Nutrient Intake and Early-Life Programming9 The Role of Systems and Policies in Providing Solutions to Nutrition Access and Equity During Pregnancy and Lactation10 Reflections on the WorkshopReferencesAppendix A: Acronyms and AbbreviationsAppendix B: Workshop AgendaAppendix C: Biographical Sketches of Workshop Speakers and Moderators
