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.

How Diet Enhances Our Natural Anti-Cancer Response
September 28, 2017 One of the ways the body controls the overall number of cells is by initiating a preprogrammed cell death routine, known as apoptosis, in damaged or otherwise unnecessary cells. Apoptosis allows elimination of cells without induction of an autoimmune response. A hallmark of many types of cancer cells is a resistance to apoptosis; hence, tumors continue to grow and metastasize. Finding ways to defeat this resistance in cancer cells is an area of active research.
Polyphenols: Colorful, Healthy, Plant Compounds You May Already Eat & Drink
September 28, 2017 – Many of the foods you eat are loaded with polyphenols: plant-based compounds that are anti-oxidant, anti-inflammatory and anti-infection. Polyphenols are considered non-nutritional, meaning that they help prevent disease and keep you healthy in a different way than vitamins, minerals, or other nutrients like carbohydrates, fats, and protein. David Nieman, DrPH, director of the Appalachian State University Human Performance Lab at the North Carolina Research Campus (NCRC), explains that polyphenols are a type of phytochemical, the colorful chemicals in plants that confer a variety of health benefits. “In many fruits and vegetables, all the colors that you see are the polyphenols,” he says. “That’s what you want, a lot of color in your diet.”

Build Stronger Muscles with All Kinds of Protein
August 28, 2017 – From the desks of Martin Kohlmeier, MD, PhD and Robyn Amos-Kroohs, PhD
Protein is an important part of every cell in the body. Protein is also a building block of enzymes, hormones, and other important substances used in body processes. It’s a major component of most body systems, including the immune system, metabolism, and circulatory system. Its importance is why protein is known as a macronutrient, meaning that large amounts are required to help the body function appropriately on a daily basis. And unlike sugar and fats, macronutrients that have acquired bad reputations, protein is recognized as an important part of a healthy diet.
The Ironies of Iron During Pregnancy
August 28, 2017 – Iron is listed by the American Pregnancy Association as one of the nutrients essential for healthy fetal development. Why? Because a lack of iron, a mineral naturally found in foods like meat, seafood and vegetables, directly impacts the development of the fetal brain. Iron also prevents anemia, low birth weight and premature delivery. Unfortunately, 22 percent of US women in their childbearing years are iron deficient, says Susan Smith, PhD, deputy director of science at the UNC Nutrition Research Institute on the NC Research Campus.
UNC-CH Nutrition Research Institute Graduate Student Housing Opens Steps Away from NCRC Main Campus
June 27, 2017 • The Nutrition Research Institute (NRI) offers unique learning and work experiences for graduate students in the fields of nutrigenomics and metabolomics. Our research relies, in fact, on the work these students do. But until recently the institute has been short on student housing, creating hardship for those who wished to study and work here. That has changed with the opening of five newly refurbished houses a short walk from the institute and the rest of the North Carolina Research Campus, offering both short- and long-term student housing options.
