She is a founding member and vice president of Nutrition and Health Associates, an information and resource center in Tallahassee, Florida, that maintains an ongoing bibliographic database tracking research in more than 1,000 topic areas of nutrition. Her textbooks include "Life Choices: Health Concepts and Strategies"; "Making Life Choices"; "The Fitness Triad: Motivation, Training, and Nutrition" and others.

Ellie Whitney grew up in New York City and received her B.A. and Ph.D. degrees in English and biology at Harvard and Washington Universities. She taught at both Florida State University and Florida A&M University, wrote numerous newspaper columns on environmental matters for the Tallahassee Democrat and co-authored almost a dozen college textbooks on nutrition, health and related topics, many of which repeatedly reappear in new editions. She spent three decades exploring outdoor Florida and studying its ecology, then co-wrote "Priceless Florida: Natural Ecosystems and Native Species." In her retirement, more concerned about climate change than any other issue, she volunteered full-time for the nonpartisan national nonprofit Citizens Climate Lobby.

Mary Wissmann, M.S., R.D.N., L.D., began her study of nutrition in the Dietetics Program at University of Missouri in 2000 and continued through graduate school, earning a B.S. in Medical Dietetics and M.S. in Nutrition Science. Upon completion of graduate school, she worked as a Regional Nutrition Specialist for the University of Missouri Extension, becoming proficient in community nutrition programming and curriculum development. She specialized in translating research-based information into practical nutrition education programs and addressing food insecurity through small food retailer initiatives. While raising her three young children, she worked in private practice with a focus on behavior change and body neutrality. Never straying far from her roots, she returned to the University of Missouri as an adjunct teaching faculty in 2020, where she currently teaches introductory nutrition, as well as an integrated nutrition and cooking course each semester. She is passionate about interpreting nutrition science for practical application in daily life and giving students the context and information they need to sort fact from fiction.
