Microbiome and Nutrition
The complex community of bacteria, yeasts and viruses living in our intestines, collectively known as the gut microbiome, is shaped, in part, by what we eat. Genetics, environment, and other factors also influence an individual’s microbial community. Research at the NRI investigates these complex relationships and their impact on disease risk. We use animal models and bioinformatics to study the associations between nutritional metabolites, gut microbiome, and health. What happens in the gut doesn’t stay in the gut. Your microbiome can play a role in cardiovascular disease, obesity and diabetes, and even cancer. Our team envisions a future where analysis of your microbiome can determine disease risk, and medical foods can be prescribed to treat and prevent disease by regulating the microbiome.

Preventing Fetal Alcohol Spectrum Disorders (FASD)
November 24, 2015 • From the desk of: David Horita, Ph.D.
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.
Healthy Brain Function Tied to Nutrition
November 24, 2015 • The research in Dr. Carol L. Cheatham’s Nutrition and Cognition lab focuses on effects of nutrition on brain development and function throughout the lifespan. In her work, she is exploring the importance of certain nutrients and foods to the development, maintenance, and lifelong integrity of the hippocampus and frontal brain areas. Nutrition is integral to fetal and infant brain development, which sets the stage for lifelong learning. At the other end of the spectrum, it is beginning to be evident that nutrition is also important in senescence in that certain nutrients coupled with other healthy lifestyle choices can slow the progression of age-related cognitive decline. Dr. Cheatham has active studies in four age groups; some of that work is summarized here.
NRI Researcher Receives Award to Further Work on Obesity and Cancer
December 1, 2015 • University of North Carolina (UNC) at Chapel Hill professor Stephen Hursting has received a prestigious National Cancer Institute (NCI) Outstanding Investigator Award (OIA), which provides stable funding for cancer research with breakthrough potential. Dr. Hursting, a professor in UNC’s Department of Nutrition, Nutrition Research Institute and Lineberger Comprehensive Cancer Center, is one of 43 researchers nationwide to receive an OIA. The grant will provide Hursting with $5.34 million over a seven-year period to further his research on the mechanistic links between obesity and cancer.
