This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

Does a longer life mean a healthier life? The number of adults over 65 in the United States is growing, but many may not be aware that they are at greater risk from foodborne diseases and their nutritional needs change as they age. The IOM's Food Forum held a workshop October 29-30, 2009, to discuss food safety and nutrition concerns for older adults.

Go beyond aging theories and examine the physiological and physical impacts of aging. Exercise and Physical Activity for Older Adults takes a close look at the physical implications of the aging process and how health, physical activity, and exercise interact in aging adults. With an international team of contributors composed of leading experts from across the field of gerontology, Exercise and Physical Activity for Older Adults delivers comprehensive, interdisciplinary coverage of the physical aging process and its effects on movement and exercise. Research on the physiological and physical implications of aging is presented, focusing on study outcomes and their practical application in optimizing healthy aging. Presented in an integrated and cohesive manner, this text is organized into four parts. Part I covers the theoretical foundations of biological aging, the implications of aging theories on medical research, and the social and economic impacts of demographic shifts due to population aging and global population size. Part II addresses age-related changes to the musculoskeletal, cardiovascular, pulmonary, and endocrine systems. Part III covers the physical effects of aging on other dimensions of life, including balance, motor control, and physical functions. Part IV focuses on exercise and older adults, taking an in-depth look at exercise measurements and the main barriers to regular exercise. One full chapter is devoted to recommendations for optimizing health for the general public, while another chapter is focused on performance by elite older athletes who exercise beyond functional fitness. Chapter objectives, end-of-chapter summaries, and review questions highlight key concepts and promote learning retention. Behavior Check sidebars look at the impacts of aging on behavior, how behavior affects physical health and activity, and how changes in behavior can improve everyday living. Functional Fitness Checkup sidebars focus on the performance of daily movements that are vital for older adults who want to maintain their physical independence. Putting It Into Practice elements provide examples of real-life application of the concepts presented, facilitating a practical understanding of how to use the content to benefit clients. A definitive resource for students and health care professionals who study physical aging, conduct clinical research, or work with older adults as clients and patients, Exercise and Physical Activity for Older Adults helps readers understand the aging process and its effects on movement, exercise, and other dimensions of life.

Human nutrition.

Humanity is aging. In the last century, life expectancy has increased by as much as 25 years, the greatest increase in 5'000 years of history. As a consequence the elderly constitute today the fastest growing segment of the world's population. This new situation creates many social problems and challenges to health care which both the developed as well as the developing countries will have to cope with. The present publication shows that scientific progress has reached a level where nutritional interventions may play a decisive part in the prevention of degenerative conditions of age, improvement of quality of life and impact on health care burden and resources. Topics deal with such different aspects as the influence of prenatal and early infant nutrition on the future aged individual and effects of energetic restriction on longevity. Further contributions include studies on mitochondrial alterations, digestive problems, specific metabolic deviations mediated by insulin, bone degradation, structural changes, neuromuscular dysfunctions, mental state of the elderly as well as the response of the immune system to nutrient intake. Finally the book offers a review of requirements appropriate to meet the age-related public health challenges of the 21st century.

This book provides the first comprehensive overview of a new scientific discipline termed Geroscience. Geroscience examines the molecular and cellular mechanisms that might explain why aging is the main risk factor for most chronic diseases affecting the elderly population. Over the past few decades, researchers have made impressive progress in understanding the genetics, biology and physiology of aging. This book presents vital research that can help readers to better understand how aging is a critical malleable risk factor in most chronic diseases, which, in turn, could lead to interventions that can help increase a healthy lifespan, or ‘healthspan.’ The book begins with an analysis of the Geroscience hypothesis, as well as the epidemiological underpinnings that define aging as a candidate main risk factor for most chronic diseases. Next, each chapter focuses on one particular disease, or group of diseases, with an emphasis on how basic molecular and cellular biology might explain why aging is a major risk factor for it. Coverage in the book includes: cancer, cardiovascular disease, dementias, stroke, Parkinson's and Alzheimer’s diseases, osteoporosis, arthritis, diabetes asthma, emphysema, kidney disease, vision impairment, and AIDS/HIV. It finishes with a chapter on pain in the elderly and an overview of future steps needed to bring the newly acquired knowledge into the clinic and the public at large.
