February 17, 2016 • Folami Iderraabdullah is an assistant professor in the Department of Genetics in the UNC School of Medicine and a researcher at the Nutrition Research Institute in Kannapolis. Her research looks at the genetic differences between individuals to determine how the cells in the body respond to changes in diet.
February 1, 2016 • The Zeisel laboratory at the UNC Nutrition Research Institute (NRI) is well known for defining the importance of the nutrient choline in infant brain development. They discovered that choline in mother’s diet during pregnancy is extremely important for optimal brain development in her baby. But, is this the only time in life that choline can improve brain function? Could teenagers eat extra choline to help their school performance?
January 28, 2016 • Cereal, pasta, bread, cookies – what do they have in common? The answer is “folic acid,” a synthesized form of a naturally occurring B vitamin called folate. Folate occurs naturally in some foods such as green leafy vegetables, avocados, red meat and lentils. Almost any processed food made with flour has folic acid.
January 2, 2016 • Children of mothers whose diet during pregnancy was deficient in the essential nutrient choline have lower performance on cognitive tests. Cognition is rooted in the brain’s cortex, but a direct link between maternal dietary choline levels and cortical development in offspring had not been demonstrated. Experimental evidence of this link, and identification of a physiological mechanism, would greatly enhance our understanding of the importance of proper nutrition during pregnancy.

THE STUDY
In a recently published paper1, NRI investigator Phil May and colleagues showed that the prevalence of fetal alcohol syndrome (FAS) and partial fetal alcohol syndrome (PFAS) is two to three times higher than previously estimated.
Dr. May’s study differs from most FAS prevalence studies in its use of active case ascertainment testing methods to estimate prevalence. This technique includes developmental testing of the child and detailed one-on-one interviews of the mother. The interview questions covered alcohol use during pregnancy, but also asked questions related to secondary factors, such as overall drinking history, marital status; socioeconomic status, and diet/nutrition. This approach is much more labor-intensive than the more common survey approach that relies on self-reported alcohol use information. However, it is also more accurate: self-reported alcohol usage surveys often underestimate FAS because of the stigma of drinking during pregnancy.
