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.

Do you have the cure for the common cold?

February 26, 2018 – Everyone gets the common cold; hence, its name. Why isn’t there a cure or preventative vaccine? Actually there is, and you have it already – an active lifestyle including regular physical activity. David Nieman, DrPH, FACSM, the director of the Appalachian State University Human Performance Laboratory at the NC Research Campus, explains.

Study of first-graders shows fetal alcohol spectrum disorders prevalent in US communities

February 6, 2018 – Philip A. May, PhD, research professor at the UNC Nutrition Research Institute, led NIH-funded research that examined over 6,000 children to determine prevalence of FASD ranged from 1.1 to 5 percent.
A new study of more than 6,000 first-graders across four U.S. communities has found that a significant number of the children examined, as many as 5 percent in one community sample, may have fetal alcohol spectrum disorders (FASD). Funded by the National Institute on Alcohol Abuse and Alcoholism (NIAAA), part of the National Institutes of Health, the new findings may represent more accurate prevalence estimates of FASD among general U.S. communities than prior research. Previous FASD estimates were based on smaller study populations and do not reflect the overall U.S. population.
