Weston Price

Weston Andrew Price (1870–1948) was an American dentist and nutritionist who became one of the most influential figures in nutritional science during the early 20th century. A graduate of the University of Pennsylvania's dental school, Price dedicated his career to investigating the connection between nutrition, oral health, and overall well-being. Between 1931 and 1948, he and his wife traveled across the globe—from Switzerland to Peru, from Africa to the Pacific Islands—studying the dietary habits and health outcomes of isolated populations that had maintained traditional food systems. His observations revealed remarkable correlations between consumption of whole, unprocessed foods and excellent dental health, strong skeletal development, and disease resistance. Price documented that indigenous populations consuming their ancestral diets experienced virtually no tooth decay, while those adopting modern processed foods rapidly developed dental disease and degenerative conditions. His seminal work, "Nutrition and Physical Degeneration" (1939), challenged prevailing nutritional dogmas and became foundational to the natural foods movement. Though some of his interpretations have been debated by modern science, Price's emphasis on whole foods and the dangers of nutritional depletion remains influential among nutrition advocates and holistic health practitioners worldwide.
