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.

The DNA Diet: Knowing How Your Genes Can Help You Fit Into Your Jeans May 20, 2019 – How are we expected to make healthy choices about food when the headlines are so confusing? We all suffer whiplash when we read butter is bad, then butter is good; when red meat is...
The Choices I.C.A.N. Make
January 25, 2019 – Pregnant women are often consumed by dietary choices such as finding a great prenatal vitamin, eating foods that will promote fetal growth, and doing everything they can to protect their pregnancy. After delivery, however, the mother’s preoccupation with her diet often pauses for four to six months. The Cheatham Nutrition & Cognition Lab is turning this type of thinking on its head with the belief that what women eat while breastfeeding greatly impacts their breastmilk and ultimately, their children’s development.
January Faculty Focus: Philip May, PhD
January 11, 2019 – “I’ve been called ‘tenacious’,” says Philip A. May, PhD, with a hint of humor. It’s an understatement for the man who relentlessly pursues data that shed light on important public health issues across the United States and around the globe. May, professor of nutrition at the UNC Nutrition Research Institute (NRI) and in the Department of Nutrition at the Gillings School of Global Public Health at UNC-Chapel Hill, has been a demographer and epidemiologist for the better part of 50 years. He calls his style of research “shoe-leather” epidemiology, meaning that he gathers information for studies by getting out in the field and immersing himself in communities to really know the people in his studies. For nearly 30 of those years, May’s focus has been on learning about the often-dire effects and alarmingly high prevalence of fetal alcohol exposure.
Women’s Health, Preconception Nutrition, and the Right to Choose
December 16, 2018 – If you’ve ever been around a pregnant woman, you’ve probably heard her mention something about food cravings. Or she’s mentioned that she won’t drink coffee or eat Oreos because they are “bad for the baby.” Food is a hot topic during pregnancy because of how it can drastically affect the developing baby. But how many times have you heard a woman mention that she is eating healthier because she is going to try to get pregnant?
December Faculty Focus: Susan Sumner, PhD
December 15, 2018 – Through the ages, science has often been in the company of poetry. They came together recently when Susan Sumner, PhD, described how she got her start in Biomarker Discovery using spectroscopic methods as an undergraduate at North Carolina State University (NCSU): “I found it exciting to envision molecules dancing in multidimensional space in response to applied physical factors such as magnets, radio frequency pulses, or electric fields.”
