About the study: PHENYLALANINE-REQ-PREGNANCY is trying to determine the amount of dietary phenylalanine required by women during pregnancy to ensure healthy development of their baby.  Pregnancy is a critical time that necessitates sufficient nutrition to ensure healthy development of both the mother and the baby.  Amino acids such as phenylalanine are the building blocks of protein, which are used to create body tissue and support the immune system.  Phenylalanine must be obtained through the diet, and the requirements during pregnancy are not currently determined. Inadequate protein and amino acid consumption during pregnancy has been linked to future risk of high blood pressure, heart disease, and other metabolic problems in the baby.  Therefore, it is important to determine how much phenylalanine should be consumed during pregnancy.
