Facsimile reprint of the first edition, complete with 134 figures. Profusely illustrated. First published in 1939, Nutrition and Physical Degeneration is one of the most remarkable and enduring works in the history of nutritional science. Written by Dr. Weston A. Price, a Cleveland dentist who spent a decade traveling to remote corners of the globe, the book documents his extraordinary firsthand observations of traditional populations living on ancestral diets - from Swiss mountain villages and Scottish island communities to African tribes, Pacific islanders, and indigenous peoples of the Americas. What Price found everywhere he looked was the same striking pattern: people eating their traditional whole foods displayed exceptional physical development, near-perfect dental arches, and robust resistance to disease. The book's central and controversial argument is that the introduction of modern processed foods - refined flour, sugar, canned goods, and vegetable oils - triggered rapid and measurable physical deterioration within a single generation. Price documented this degeneration with meticulous photography and anthropometric data, showing narrowed dental arches, crowded teeth, altered facial structure, and increased susceptibility to chronic illness in the children of populations that had recently adopted Western diets. His findings challenged the nutritional orthodoxies of his time and continue to provoke debate among researchers, clinicians, and policymakers to this day. Decades ahead of its time, Nutrition and Physical Degeneration anticipated many of the concerns now central to ancestral health, functional medicine, and the broader critique of the modern food supply. For researchers, nutritionists, anthropologists, and anyone seeking to understand the deep relationship between diet, physical development, and human health, Price's landmark study remains an essential and irreplaceable reference - a work of careful observation and passionate inquiry that has never been surpassed in its scope or its implications.
