Dr. Folta is passionate about spreading the word of good science, especially on misunderstood topics like genetic modification. Kevin Folta is a professor and chairman of the horticultural sciences department at the University of Florida. Dr. Folta received his Ph.D. from the University of Illinois at Chicago in molecular biology in 1998. Within his lab he researches photomorphogenesis in plants and compounds responsible for flavor in strawberries. Folta's laboratory has two primary research areas: controlling plant traits using light, and using genomics to identify molecular markers for key fruit-plant traits. Folta has been active as a science communicator since 2002, especially relating to biotechnology and genetic engineering. Folta has formal training in communication and has been recognized for his skill by scholarly institutions. He uses his experience to provide workshops to teach scientists and farmers how to communicate science effectively. Just recently, Dr. Folta won the 2016 Borlaug CAST Communication Award. Folta operates the Talking Biotech podcast which is billed as "A science-based assessment of new technology and the future of food",[30] in which he interviews agriculture scientists and experts in the fields of science and communication to discuss the genetic improvement of plants, animals, and microbes and other issues in biotechnology.

Episode 119: Krista Casazza PhD, discusses myths surrounding obesity, the role of epigenetics and the importance of the musculoskeletal system in weight loss maintenance and metabolic health. Dr. Casazza is an associate professor in the Department of Pediatrics at the University of Alabama. Working with the pediatric population, Dr. Casazza’s research interest have evolved into understanding the resource partitioning during critical periods of growth and development with primary focus on the bone fat interface. Krista Casazza obtained her PhD from Florida International University in 2006, where her research focused on dietary and physical activity education interventions in adolescents. During her training Dr. Casazza investigated the effects of macronutrient modification (carbohydrate in particular) on reproductive hormones, insulin dynamics and body composition during a weight loss intervention in peri-pubertal African American girls.

Episode 118: Caoileann Murphy PhD is on the show to discuss protein metabolism, distribution and recommendations on per meal vs. daily basis.
