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.

October Faculty Focus: Saroja Voruganti, PhD
October 17, 2018 – Saroja Voruganti, PhD, has covered a lot of ground in her journey to becoming a faculty researcher in nutrition, genetics, and epidemiology at the UNC Nutrition Research Institute. Born into a traditional south Indian family, she grew up in Delhi in northern India where she graduated with an undergraduate degree in nutrition. Then she married and moved to western India. Even as she focused on marriage, home, and raising a family in the traditional Indian way of life, she kept alive her dream of pursuing advanced studies and contributing outside of family life.
Choline in Human Milk Plays a Crucial Role in Infant Memory
October 3, 2018 – Choline is present in human milk, and is especially important for fetal and infant development [2,3]. “The hint that choline is important for infant development comes from the fact that in human milk, the supply of choline remains constant across the first year of life,” says Professor Carol Cheatham from the University of North Carolina at Chapel Hill. Other important nutrients, such as docosahexaenoic acid (DHA), are present in large quantities initially, but often level off after a few months.
Culinary twist: Healthy food that helps the community
September 28, 2018 – Good Bowls taps into the UNC innovation network and brings locally sourced meals to lower-income consumers. Social innovation is nothing new at the University of North Carolina at Chapel-Hill. And using its long history of social innovation as a cornerstone, one UNC venture is blazing a trail to improve community health. If you haven’t already heard of Good Bowls, you will.
Celebrating a Decade of Nutrition Discoveries
September 28, 2018 – This October, the NRI proudly marks its tenth anniversary of delving into the science of Precision Nutrition. What began in 2008 with two faculty members and a supporting staff of nine is, today, a bustling center of scientific inquiry and discovery with a staff of 82, which includes 16 principal investigators.
Leptin’s Role in Cancer Susceptibility
August 30, 2018 – While the link between obesity and breast cancer risk is well known, the underlying mechanisms are not fully understood. Obesity alters many conditions in cells and within the body, and it is not easy to determine which of these conditions are important to the obesity-cancer link. Consequently, it is very difficult to identify potential therapeutic targets.
Cheatham Lab Memory Game Pilot Study
August 30, 2018 – The Cheatham Nutrition & Cognition Lab at the NRI is undertaking a new pilot study with 12- and 24-month-old children called the Memory Game Pilot Study. In this study the lab seeks to validate the props used in the elicited imitation paradigm, a nonverbal means of assessing recall memory in preverbal children. The props, which have been designed and produced in the Cheatham lab, will be implemented with a group of young children of the same ages in an already-planned, collaborative study with Emory University.
