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.

Nutrient Bar Results in Broadscale Health Improvements After Only Two Months

May 1, 2015 • A fruit-based micronutrient and fiber-dense supplement bar (the “CHORI-bar”), conceived by Drs. Bruce Ames and Mark K. Shigenaga at Children’s Hospital Oakland Research Institute (CHORI), was shown in clinical trials to improve metabolism in overweight/obese (OW/OB) otherwise healthy adults in ways that are consistent with reduced risk of type 2 diabetes and cardiovascular disease. Consumption of the bar for two months also reduced chronic inflammation, and initiated a reduction in weight and waist circumference. Decreased inflammation and improved weight and weight distribution can lower the risk of many chronic diseases.

UNC-Chapel Hill explores “Food for All” with 2015-2017 campus theme

April 30, 2015 • The University of North Carolina at Chapel Hill will come together at a common table when it examines food and food studies as its 2015-2017 university-wide academic theme. “Food for All: Local and Global Perspectives,” which builds on Carolina’s 2012-2015 “Water in Our World” focus on global water issues, will challenge all areas of the University to examine wide-ranging topics from food cultures and nutrition, to food security, world hunger, agricultural economics, resource management, sustainable development, climate change and international trade.

Eat More Produce, Reduce Cancer

April 29, 2015 • It’s spring! Farmers markets are opening and these are great places to find a variety of local, seasonal produce, which flourishes now. Making room for these powerhouses in your everyday food choices is important for your health. A 2012 peer-reviewed analysis in Food and Chemical Toxicology states that approximately 20,000 cancer cases could be prevented every year if one-half of Americans were to increase their serving of fruits and vegetables by one serving per day.
