Kayellen Umeakunne, MS RDN LD, Research Bionutritionist, Morehouse School of Medicine (MSM) Georgia CTSA Clinical Research Center (GCRC) recently co-authored a manuscript about the role of the gut microbiome in the development of chronic metabolic and autoimmune diseases and disorders. The findings were published in EC Nutrition in "The Gut Microbiota, Obesity and the Effect of Dietary Modulation and Bariatric Surgery on the Microbiome: A Review of the Literature".
Through a review of major publications, the research team investigated trends and associations in obesity and gut microbiota. Their findings included there are distinctive changes in the gut microbiome associated with obesity. Dietary modulation and bariatric surgery have a significant effect on the constitution of the gut microbiome.

All key cores were involved in the conduct of my study including the Bionutrition Core Research Kitchen and Body Composition Lab, Nursing Core, Analytical Lab, Research Design and Biostatistics Core, Recruitment Core, Regulatory Core, Administrative Core and the Research Subject Advocate. It takes a multi-disciplinary team approach to conduct quality research," says Umeakunne.
