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.

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.
