Episode 55 Decoding the Interactions Between Exercise, Diet, and Gut Microbiota

In this enlightening episode, we discuss the role of gut microbiota in chronic diseases, its impact on organs like the brain, and how factors like sex, diet, and exercise influence it. We throw light on the good, the bad, and the misunderstood bacteria within us, questioning the oversimplified labels of "good" and "bad" bacteria. We discuss how exercise and diet may lead to a healthier microbiome, and the potential for functional redundancy among the thousands of types of bacteria in our gut. Dr. Campbell shares her experience and research on the relationship between gut microbiota and exercise, shedding light on fascinating elements like butyrate, propionate, and acetate.

About our guest:
Dr. Sara C. Campbell is an Associate Professor in the Department of Kinesiology and Health at Rutgers. She received her B.S. and M.S. from Bloomsburg University of Pennsylvania and her Ph.D. from Florida State University. Following her Ph.D., she completed a three-year postdoctoral fellowship supported by the USDA investigating the ability of flaxseed to reverse atherosclerotic lesions. At Rutgers, the Campbell lab investigates the intersection of sex, diet, and exercise on the gut microbiota, and intestinal and systemic health. The Campbell Lab has recently focused on the links between gut microbiota, brown adipose tissue, skeletal muscle, and environmental toxicants like ozone. The Campbell Lab has published papers on how exercise impacts gut microbial ecology and intestinal inflammation and permeability in a sex specific manner, how gut microbiota depletion impacts exercise capacity and mitochondrial content of key proteins related to oxidative phosphorylation and biogenesis, hormone deficiency (estrogen in particular) and gut health and the bidirectional link between the gut microbiota and exercise.
