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.

Understanding Nutrigenomics

March 2, 2015 • Why “good” and “bad” are irrelevant when talking about genes and nutrition
From the desk of: Mihai Niculescu, M.D., Ph.D.
…“How to override your bad genes with food.” “Can Exercise Override Bad Genes?” “Good Nutrition Can Overcome Bad Genes”…
woman drawing dnaWe are bombarded by media with these kinds of messages. The main theme, of course, is that many of us may have “bad” genes that would put us at risk of a certain poor health outcome unless we eat less of “this” and more of “that.” Knowing myself as a bearer of several such genetic variations, I almost feel, at times, guilty that I am harboring such “bad” genes, albeit without my consent.

NRI Scientist Achieves New Role

March 2, 2015 • Natalia Surzenko, Ph.D., studies the connections between nutrients and brain and eye development. Her work in this area has been as Research Scientist in the Zeisel lab since joining the NRI in 2013. In recognition of the excellence she brings to her research, Dr. Surzenko has been promoted to Research Assistant Professor.

Series to help laypeople understand science

Saturday, February 14, 2015 • The following has been reprinted from Charlotte Observer, an article by Lisa Thornton. If Dr. Natalia Surzenko told you that choline produces increased hippocampal neurogenesis in Mus musculus, you probably wouldn’t understand. But if she said a nutrient called choline, naturally found in foods such as egg yolks, salmon and cocoa powder has been shown to regenerate brain cells responsible for increased memory in mice, that would be different. At the UNC Nutrition Research Institute in Kannapolis, where Surzenko, a neurobiologist, has her lab, a new series called “Appetite for Life” is intended to create clearer dialogue between researchers and laypeople about discoveries changing the way experts view nutrition.

Choline: An Essential Nutrient

Choline: An Essential Nutrient

Makes Babies Smarter, Keeps Memory Keen and Prevents Disease, Yet Most Americans Are Missing Out
Choline was discovered in 1862, but scientists did not fully understand its importance—or what foods contained it—for another 136 years. They thought we could make our own choline, much like we make Vitamin D from sunlight and cholesterol, but only women who still produce estrogen can make enough choline—and only if they have the right genes. Forty-five percent of child-bearing women have a genetic variation called a SNP (pronounced “snip”) that prevents them from turning estrogen into choline.
