The surprising origins, spread, and continued contradictions of our sweeping obsession with healthy eating.

The Battle for Health tells the story of one of the modern world’s most influential yet misunderstood cultural movements. Emerging in the nineteenth century as a reaction against industrial food production, chemical additives, and the growing authority of conventional medicine, the health food movement reshaped how people thought about eating, health, and personal responsibility. This first full-scale history traces its path from vitamin pioneers, organic farmers, and dietary reformers to today’s wellness industry and debates over nutrition, sustainability, and public policy. It reveals a movement marked by striking contradictions: science and romanticism, innovation and quackery, individual choice and collective change. Lively, wide-ranging, and deeply relevant, it shows how everyday food choices became a powerful force in shaping modern society.
