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.

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.
