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.

Maternal Vitamin D For Preventing Autism

July 27, 2017 – Vitamin D deficiency in pregnant moms is shown to negatively affect fetal growth and children’s health in the long run. Deficient gestational vitamin D status is surprisingly high both globally and in the US. One of the findings that draws attention is the role of vitamin D during pregnancy in children’s chances of developing Autism Spectrum Disorders (ASD). Vitamin D is acquired through sun exposure or food intake. The circulating form of vitamin D can travel through the fetal-placental barrier, thus, developing babies depend solely on their mothers for getting this beneficial nutrient.

Choline Biomarker Study Call for Participants

August 28, 2017 – The Zeisel Lab at the NRI is recruiting participants for a clinical study on the essential nutrient choline. The lab needs healthy females and males between the ages of 17 and 70 to take part in a six-week study. Participants will be asked to provide blood samples and will eat meals provided by the NRI during the course of the study. “Healthy” means normal body weight, and no smoking, drug abuse, unusual diets, allergy to soy, or chronic diseases.  All qualifying participants will be paid when they complete the study.

Female Tea Drinkers See Epigenetic Changes in Cancer and Hormone Genes

June 27, 2017 • That morning or midday beverage may have a greater effect on our genes than previously thought, especially if you happen to be female and consume tea on a regular basis. New evidence from a group of investigators at Uppsala University shows that tea consumption in women leads to epigenetic changes in genes that are known to interact with cancer and estrogen metabolism. Findings from the new study were published recently in Human Molecular Genetics in an article entitled “Tea and Coffee Consumption in Relation to DNA Methylation in Four European Cohorts.”
