Event Series Event Series: GGA Seminar Series

Lawrence David, Duke University

February 19 @ 1:30 pm - 2:30 pm

Using DNA sequencing to reveal new insights into human diet

Lawrence David, Associate Professor of Molecular Genetics & Microbiology; Associate Director, Duke Microbiome Center



Tracking diet by self-reporting often presents challenges, including potential inaccuracies and underreporting. To address these obstacles, we introduce an objective approach for monitoring food species based on DNA sequencing, which we call FoodSeq. This approach is capable of tracking the consumption of hundreds of different plant and animal species, and is readily adaptable to different global settings. We will also present how these dietary data can be contextualized in the context of human behavior, health, and the gut microbiome. Together, these findings suggest new perspectives on the benefits of dietary diversity, what foods drive global dietary variation, and how to recognize ultra-processed foods.

Join us on Monday, February 19 at 1:30 PM in Stephens Room (3503 Thomas Hall) and ZOOM for the Genetics and Genomics Seminar Series.

Register to attend virtually via Zoom.
