A lively cultural history of the American weight loss industry that explores the origins of our obsession with dieting As a nation battling an obesity epidemic, we spend more than $35 billion annually on diets and diet regimens. Our weight is making us sick, unhappy, and bigger than ever, and we are willing to hand over our hard-earned money to fix the problem. But most people don't know that the diet industry started cashing in long before the advent of the Whopper. The Hundred Year Diet is the story of America's preoccupation with diet, deprivation, and weight loss. From the groundbreaking measurement of the calorie to World War I voluntary rationing to the Atkins craze, Susan Yager traces our relationship with food, weight, culture, science, and religion. She reveals that long before America became a Fast Food Nation or even a Weight Loss Nation, it was an Ascetic Nation, valuing convenience over culinary delight. Learn how one of the best-fed countries in the world developed some of the worst nutritional habits, and why the respect for food evident in other nations is lacking in America. Filled with food history, cultural trivia, and unforgettable personalities, The Hundred Year Diet sheds new light on an overlooked piece of our weight loss puzzle: its origins.

In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.
