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 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.
October 27, 2015 • A recent, global study published in The Lancet (2015; 386, p.743-800) clearly emphasizes the importance of the latter referring to our quality of life. According to the Global Burden of Disease (GBD) study, worldwide life expectancy at birth rose by 6.2 years between 1990 and 2013. However, these additional years come at a price as healthy life expectancy at birth increased by only 5.4 years over the same 13 year time span.
October 1, 2015 • Antioxidants have been in the popular press for more than 20 years and, while many people may not understand what exactly antioxidants do, they have the right idea that consuming foods known to contain high levels of the compounds is better than not consuming them. In its simplest form, an antioxidant is a compound that can be consumed or that the body makes to defend against damaging effects of free radicals, highly reactive molecules that can damage cells and tissues. We are exposed to free radicals through everyday living.
September 21, 2015 • A new study from scientists at the NC Research Campus (NCRC) in Kannapolis, NC, found that certain phytochemicals build natural, cellular defenses against damaging free radicals and reactive oxygen species dispelling other popular theories of how some antioxidants work.
