Genes and Nutrition
Each of us is metabolically unique. Gene variations known as SNPs (single nucleotide polymorphisms) often are a factor in an individual’s ability to metabolize or use nutrients efficiently. Each of our specific nutrient needs is affected by which specific combination of SNPs we have, but with thousands known to impact nutrition metabolism, how do we know what those needs are?
NRI researchers are working to create a “catalog” of SNPs that alter our nutritional needs by understanding how genetic and other complex biological information can be used to better estimate individual nutrition requirements and intolerances. Our scientists use bioinformatics to extract such information from population and intervention studies, develop rules for predicting individual needs, and bring precision nutrition to health care providers and consumers with digital tools.

Dr. Hursting Awarded Grant from Breast Cancer Research Foundation
October 28, 2015 • The Breast Cancer Research Foundation seeks “to prevent and cure breast cancer by advancing the world’s most promising research.”Since 1993 BCRF-supported investigators have been deeply involved in every major advance in breast cancer prevention, diagnosis and treatment. In 2015-2016, BCRF is awarding $48.5 million in grants to more than 240 scientists to advance this work. Among those recipients is Stephen Hursting, Ph.D., M.P.H., Professor of Nutrition at the UNC Nutrition Research Institute.
Is Life Expectancy a Good Measure of Health?
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.

Researchers Say Absolutely No Drinking While Pregnant
October 21, 2015 • Fetal Alcohol Syndrome (FAS) in the United States has long been estimated at no more than three children per 1,000. A new study published in the journal of Drug and Alcohol Dependence reports that the prevalence of fetal alcohol syndrome (FAS) is between 3 and 8 per 1,000 and when combined with partial FAS (PFAS) the prevalence of both actually ranges between 11 to 25 children per 1,000.
Lead researcher Philip May, Ph.D., research professor with the UNC Nutrition Research Institute (NRI) at the NC Research Campus in Kannapolis, NC, emphasized that the study “Prevalence and characteristics of fetal alcohol syndrome and partial fetal syndrome in Rocky Mountain Region City” is only the second population-based study completed in the United States that aimed to establish more accurate rates of FAS and PFAS.

Our Built-In “Antioxidant” System
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.
