The Cornell Choline Cognition Research Group investigates the effects of maternal choline intake during pregnancy on offspring cognitive and neurobehavioral development.  Choline is an essential nutrient found in many foods, but most commonly in egg yolks, lean red meat, fish, poultry, milk, legumes, nuts and cruciferous vegetables; it is also available as a nutritional supplement. Choline has many key roles in health and disease prevention, but adequate maternal choline intake is especially important for optimal prenatal brain development and lifelong offspring cognitive functioning.  

Our research team uses experimental methods to identify the optimal amount of choline to be consumed during pregnancy, with respect to child cognitive outcomes.  We examine the causal effects of maternal choline supplementation on offspring memory, attention, information processing speed, and executive functioning from early infancy into childhood.  Through our studies, we seek to advance scientific knowledge and understanding of how variations in maternal choline intake affect offspring neurobehavioral development from infancy into old age. In addition, we seek to provide evidence that will inform dietary intake guidelines for pregnant women.
