March 21
The “Natural” Human Diet – George Diggs

Dr. Diggs will divulge some surprises about plants, evolution, and our health.

Plants, including many native to Texas, have evolved an amazing array of chemical defenses to protect themselves from being eaten by herbivores.  These include toxins that physically damage the plant eaters, disrupt their metabolisms, and damage their hormone systems. Recent research has also uncovered new and surprising information about what really is a healthy diet for people.  This talk will pull together the recent botanical research with that about diet and health, and attempt to explain why many aspects of modern health (including obesity, diabetes, and autoimmune diseases) are becoming worse instead of better.  This will be tied with the evolution of our species and the plants and plant products we eat.

George Diggs is an evolutionary biologist and botanist who hastaught for more than 30 years at Austin College in Sherman, Texas.  His research interests include the plants of Texas, plant defense, evolution as it relates to human health, and biogeography.  He has co-authored four books and more than 30 scientific articles and in his research he has traveled to all seven continents. His latest books are The Hunter-Gatherer Within: Health and the Natural Human Diet (2013) and The Ferns and Lycophytes of Texas (2014).
