Maternal Carotenoids Across Pregnancy Study

Before infants are born, they depend on their mother to provide the nutrients necessary to grow and develop, such as iron, folic acid, iodine and other vitamins and minerals. Pregnant people also rely on good nutrition to support their own health. In addition to essential nutrients, vitamins, and minerals, there are other natural components found in fruits and vegetables, called phytochemicals, that may support maternal and fetal health during pregnancy. While more is known about the role of phytochemicals in adult health, surprisingly little is known about phytochemical nutrition during pregnancy. This study focuses on a group of phytochemicals, called carotenoids, during pregnancy. The study will determine if and why levels of carotenoids in the body change across the course of pregnancy. Understanding carotenoid nutrition during pregnancy will improve the understanding ofnutrition needs of expectant mothers and their infants. To study these questions, both health pregnant and non-pregnant female adults will report on their dietary intake and participate in body measurements, health surveys, and carotenoid measurements of eyes, skin, and blood at time points corresponding with the first, second, and third trimesters of pregnancy as well as post-partum.
