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.

Your Nutritional Needs Are as Unique as You Are

Your Nutritional Needs Are as Unique as You Are

June 1, 2015 • There is mounting evidence that small amounts of essential nutrients like choline and folate have a big impact on human health. However, nutritional studies that attempt to quantify the effects of essential nutrients often produce unclear or contradictory results.
There are several reasons for this, but chief among them is the assumption that all of us process food exactly the same way. This is simply not the case. No one is metabolically identical or even similar to anyone else – not even identical twins. We all require different amounts of specific nutrients and vitamins. Scientists at the UNC Nutrition Research Institute believe this common misconception is responsible for so many contradictory study results.
