The Dark Side of Wheat has changed many minds about the exalted status of wheat among secular and sacred institutions alike.

As Dr. Ron Hoggan, co-author of "Dangerous Grains" puts it in the foreword: "Sir Isaac Newton's famous metaphor (perhaps quoting others) said something to the effect that we see further, not because of any special endowment of our own, but because we are standing on the shoulders of giants. After reading Sayer's work on wheat, I felt as if I had just been boosted to a higher plane from which I could see and understand much, much more. Sayer's insights continue to shape and inform much of my effort to understand the various impacts of grains on human health.
