Book excerpt: "[A] renowned chef ... Barber explores the evolution of American food from the "first plate," or industrially-produced, meat-heavy dishes, to the "second plate" of grass-fed meat and organic greens, and says that both of these approaches are ultimately neither sustainable nor healthy. Instead, Barber proposes Americans should move to the "third plate," a cuisine rooted in seasonal productivity, natural livestock rhythms, whole-grains, and small portions of free-range meat"--Provided by publisher.
