In this illuminating book, D. Gary Young chronicles the history of ancient grains and tracks their changing relationships with humans, from staff of life to potentially harmful ingredients, hybridized wheat, and genetically modified grains, found in nearly every food product. The book discusses the benefits of einkorn grain, an ancient heirloom grain that remains untouched by hybridization. It also describes how some of the chemicals in our foods today are found to be responsible for health challenges.
