The first part of this book will help the reader better understand the biology of aging; including changes in the heart, blood vessels, skeleton, muscle and the nervous and immune systems. Four chapters are devoted to what we put in our mouths each day; food, liquid (including alcohol) and tobacco products, and how this affects our susceptibility to major chronic diseases, such as heart attack, stroke, diabetes, hypertension, and selected cancers. This association between food and disease requires that consumers learn how to interpret the Food Facts Label on retail containers so they can control how much sugar, fats, cholesterol, and total calories they ingest as a result of their food choices. Another major section of the book scrutinizes the multi-billion dollar food supplement industry (vitamins, minerals and a myriad of other dietary supplements designed to supposedly slow aging, regrow hair, reduce wrinkles and even enhance your sex life). Practical guidelines are provided so that the consumer understands the importance of prior discussion with your primary physician prior to initiating.The latter section of the manuscript is oriented to the Physical Activity Lifestyle (PAL). Beyond nutrition, there is no more important factor than your exercise habits (or lack thereof) that determine the quality of your health and life throughout the aging cycle. Today, exercise is considered a fundamental part of preventive medicine (disease intervention). A significant part of chapter six will enlighten the reader about the broad spectrum of significant health benefits that accrue from a regular and balanced exercise regimen, including effects on brain and cognitive function, avoidance of obesity and the myriad of diseases associated with the syndrome. One of the paramount objectives of your PAL will be to protect the integrity of your skeletal and muscular systems so that you can maintain an independent lifestyle. Thus, you will be able to take care of your own physical needs (Activities of Daily Living or ADL) without the help of others (Assisted Living), even as you move into advanced old age. An extensive list of science based exercise training principles are outlined to promote your own Functional Fitness (FF), which promotes the elements of: Core strength, flexibility and balance. These elements of FF are the keys to maintaining your physical independence and avoidance of falls, fractures and disability, the nemesis of older age. The very last chapter (8) integrates all the major concepts regarding aging physiology, and the latest applications of nutritional and physical activity interventions, that will assist you in planning for an enduring and qualitative life journey. ABOUT THE AUTHORGeorge J. Holland is an exercise physiologist who spent over 30 thirty years researching, publishing and teaching in the California State University system. The latter part of his professional career was devoted primarily to the study of aging physiology, and the effects of exercise on older adults. He also co-authored one of the first books on the effects of exercise on human biology (Biophysical Values of Physical Activity). Upon retirement in 2000, the author spent 6 months as a visiting research professor at Tsukuba University in Japan, collaborating on various aspects of aging physiology, nutrition, and physical activity. The Japanese experience was very enlightening, since that country enjoys the highest life expectancy in the developed world. The current publication represents the author?s cumulative perspectives regarding how lifestyle influences the quality of life (QOL) as we move through different stages of life?s journey. The major premise of this publication, is that every individual needs to understand fundamental principles of preventive medicine that allow you to take charge of your own quality of aging (QOA). As the title of this book implies, the most significant lifestyle factors related to quality aging are: what we put in our mouth each day, as well as how successfully we incorporate significant physical activity into our daily regimen.
