Federal guidance on nutrition and diet is intended to reflect the state of the science and deliver the most reliable recommendations possible according to the best available evidence. This guidance, updated and presented every 5 years in the Dietary Guidelines for Americans (DGA), serves as the basis for all federal nutrition policies and nutrition assistance programs, as well as nutrition education programs. Despite the use of the guidelines over the past 30 years, recent challenges prompted Congress to question the process by which food and nutrition guidance is developed. This report assesses the process used to develop the guidelines; it does not evaluate the substance or use of the guidelines. As part of an overall, comprehensive review of the process to update the DGA, this first report seeks to discover how the advisory committee selection process can be improved to provide more transparency, eliminate bias, and include committee members with a range of viewpoints for the purpose of informing the 2020 cycle.

Savvy, comprehensive, and authoritative, this book, written by a physician with more than thirty years experience caring for elderly patients, assesses the current state and the future prospects of Medicare, perhaps the most influential health-insurance program of our time. Christine K. Cassel draws upon the latest developments in science and medicine in a sweeping analysis of Medicare s social, demographic, institutional, political, and policy contexts. Writing in accessible language, using case studies to illustrate how policies translate to everyday lives, and applying lessons from the practice of geriatric medicine, Cassel makes a powerful argument for reforming and modernizing Medicare. She offers a new vision of what healthy aging could be and delineates what is needed to realize this vision, including changes in the medical sector, in the policy arena, and in our cultural beliefs about aging. Cassel sheds light on a wide range of issues pertaining to Medicare, including debates about coverage and the looming deficit in the Medicare trust fund. Perhaps the most controversial issue she addresses is the challenge of rationing some kinds of care. Anchoring her discussion of Medicare in the idea that care for the elderly represents a social contract between government and its citizens, Cassel describes both the principles and potential of a progressive approach to geriatric medicine. She further argues that with this approach, we can also address the chronic problems of our larger health-care system and provide all Americans, no matter what their age, with high-quality and affordable medical care.

In Sputnik's Shadow traces the rise and fall of the President's Science Advisory Committee from its ascendance under Eisenhower to its demise during the Nixon years. Zuoyue Wang examines key turning points during the twentieth century, including the beginning of the Cold War, the debates over nuclear weapons, the Sputnik crisis in 1957, the struggle over the Vietnam War, and the eventual end of the Cold War, showing how the involvement of scientists in executive policymaking evolved over time and brings new insights to the intellectual, social, and cultural histories of the era.
