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.

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.”

December 17, 2018 – Philip A. May, PhD, has received the 2018 Mark Keller Award bestowed by the National Institute on Alcohol Abuse and Alcoholism (NIAAA) at the National Institutes of Health (NIH).
Starving Cells May Lead to New Cancer Treatments
November 20, 2018 – Nutrient availability regulates cell metabolism, growth, and survival. When nutrients are in short supply, cells can pause their growth or even eliminate themselves through a process known as programmed cell death, thereby protecting the health of the organism as a whole. If nutrient deprivation happens at certain critical periods, such as during the rapid growth of the embryonic brain, severe developmental consequences can arise (this is why proper maternal nutrition is so important). In contrast, harnessing the innate ability of cells to enter programmed cell death is an important strategy in cancer treatment.
Nutrition Is a Hard Science
November 20, 2018 – There have been a lot of questions about the reliability of nutritional science. We should respond with an assertive statement: Nutrition is a hard science. By just about any comparison, much of what is known about nutrition and the methods that have built that knowledge is as robust as classical physics, biochemistry and other basic sciences generally recognized as rigorous.
