The purpose of the P/B-24 Project, completed in 2018, was to conduct a series of systematic reviews on diet and health for women who are pregnant and for infants and toddlers from birth to 24 months of age. This project was led jointly by USDA and HHS. USDA’s Nutrition Evidence Systematic Review (NESR) team conducted systematic reviews for the Pregnancy and Birth to 24 Months (P/B-24) Project. A Federal Expert Group (FEG), a broadly representative group of Federal researchers and program leaders, also provided input throughout the P/B-24 Project.
It is important to note that the purpose of P/B-24 Project was to review the evidence on a select number of questions, not to establish or recommend dietary guidance.
A detailed description of the P/B-24 Project has been published and is available:
