This series explores the global and local dimensions of food systems and examines issues of access, justice, and environmental and community well-being. It includes books that focus on the way food is grown, processed, manufactured, distributed, sold, and consumed. Among the matters addressed are what foods are available to communi- ties and individuals, how those foods are obtained, and what health and environmental factors are embedded in food system choices and out- comes. The series focuses not only on food security and well-being but also on regional, state, national, and international policy decisions and economic and cultural forces. Food, Health, and the Environment books provide a window into the public debates, theoretical considerations, and multidisciplinary perspectives that have made food systems and their connections to health and environment important subjects of study. Robert Gottlieb, Occidental College Series editor Preface This book is about long-term dietary change and its consequences for agricultural production, trade, food consumption, environment, and health. Its scope dictates interdisciplinary coverage and precludes any simple categorization: the book draws on findings from historical and economic studies, agronomic and agricultural analyses, and the fields of nutrition, public health, demography, and environmental science. The intent has been to present a multifaceted evaluation of a process whose nature and impact can be truly appreciated only through a broad-based inquiry. At the same time, this means that the book will disappoint if it is judged from narrow perspectives of specific expertise: it is not an exercise in economic history, nutritional science, or agricultural development. Dietary transition— a gradual shift from traditional, preindustrial diets dominated by plant foods to a new pattern of intakes that includes more animal foodstuffs, more fats, more sugar, and a greater variety of processed foods— has been a universal phenomenon, but Japan offers a particularly interesting illustration of the process with several unique characteristics. The country’ s dietary transition was a key ingredient of its modernization that made it the world’ s second largest economic power of the second half of the twentieth century. Although the transition began slowly during the Meiji era (1868– 1912), it proceeded at remark- ably rapid rates once the country repaired the massive wartime damage by the mid-1950s, and most of it was subsequently accomplished in just a single generation, a tempo that has been rivaled only recently in urban China. But perhaps its most remarkable attribute has been its saturation at levels well below the spending potential of such an affluent society. After
