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.

Folate – friend or foe?

January 28, 2016 • Cereal, pasta, bread, cookies – what do they have in common? The answer is “folic acid,” a synthesized form of a naturally occurring B vitamin called folate. Folate occurs naturally in some foods such as green leafy vegetables, avocados, red meat and lentils. Almost any processed food made with flour has folic acid.

Mother's Diet Impacts Development of Baby's Brain

January 2, 2016 • Children of mothers whose diet during pregnancy was deficient in the essential nutrient choline have lower performance on cognitive tests. Cognition is rooted in the brain’s cortex, but a direct link between maternal dietary choline levels and cortical development in offspring had not been demonstrated. Experimental evidence of this link, and identification of a physiological mechanism, would greatly enhance our understanding of the importance of proper nutrition during pregnancy.
