This book was released on 2002-01-07 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report from the Committee on Military Nutrition Research reviews the history of caffeine usage, the metabolism of caffeine, and its physiological effects. The effects of caffeine on physical performance, cognitive function and alertness, and alleviation of sleep deprivation impairments are discussed in light of recent scientific literature. The impact of caffeine consumption on various aspects of health, including cardiovascular disease, reproduction, bone mineral density, and fluid homeostasis are reviewed. The behavioral effects of caffeine are also discussed, including the effect of caffeine on reaction to stress, withdrawal effects, and detrimental effects of high intakes. The amounts of caffeine found to enhance vigilance and reaction time consistently are reviewed and recommendations are made with respect to amounts of caffeine appropriate for maintaining alertness of military personnel during field operations. Recommendations are also provided on the need for appropriate labeling of caffeine-containing supplements, and education of military personnel on the use of these supplements. A brief review of some alternatives to caffeine is also provided.

Book excerpt: Caffeine in Food and Dietary Supplements is the summary of a workshop convened by the Institute of Medicine in August 2013 to review the available science on safe levels of caffeine consumption in foods, beverages, and dietary supplements and to identify data gaps. Scientists with expertise in food safety, nutrition, pharmacology, psychology, toxicology, and related disciplines; medical professionals with pediatric and adult patient experience in cardiology, neurology, and psychiatry; public health professionals; food industry representatives; regulatory experts; and consumer advocates discussed the safety of caffeine in food and dietary supplements, including, but not limited to, caffeinated beverage products, and identified data gaps. Caffeine, a central nervous stimulant, is arguably the most frequently ingested pharmacologically active substance in the world. Occurring naturally in more than 60 plants, including coffee beans, tea leaves, cola nuts and cocoa pods, caffeine has been part of innumerable cultures for centuries. But the caffeine-in-food landscape is changing. There are an array of new caffeine-containing energy products, from waffles to sunflower seeds, jelly beans to syrup, even bottled water, entering the marketplace. Years of scientific research have shown that moderate consumption by healthy adults of products containing naturally-occurring caffeine is not associated with adverse health effects. The changing caffeine landscape raises concerns about safety and whether any of these new products might be targeting populations not normally associated with caffeine consumption, namely children and adolescents, and whether caffeine poses a greater health risk to those populations than it does for healthy adults. This report delineates vulnerable populations who may be at risk from caffeine exposure; describes caffeine exposure and risk of cardiovascular and other health effects on vulnerable populations, including additive effects with other ingredients and effects related to pre-existing conditions; explores safe caffeine exposure levels for general and vulnerable populations; and identifies data gaps on caffeine stimulant effects.

Download or read book Nutritional Neuroscience written by Harris R. Lieberman and published by CRC Press. This book was released on 2005-03-18 with total page 436 pages. Available in PDF, EPUB and Kindle. Book excerpt: Scientific and commercial interest in the field of nutritional neuroscience has grown immensely over the last decade. Today, a broad range of dietary supplements, foods for weight loss, functional foods, nutraceuticals, and medical foods are widely available. Many of these products are marketed for their effects on behavior or brain function, which relates directly to nutritional neuroscience and raises issues regarding their safety and efficacy. The only comprehensive reference on this subject, Nutritional Neuroscience discusses the relationship of nutrition to behavior and neuroscience. Following a review of fundamental issues and methods, the book covers the effects of macronutrients and micronutrients on brain function and behavior. Chapters are devoted to the effects of a wide range of foods, specific nutrients, food constituents, and food additives on cognitive behavior and development. The final section examines foods and supplements that modulate brain function. With a broad range of information presented in a simple and straightforward manner, this book provides an ideal introduction to nutritional neuroscience. The depth of information and comprehensive coverage also make this an essential reference for specialists involved in nutrition, neuroscience, pharmacology, psychology, and related disciplines.

Download or read book The 71F Advantage written by National Defense University Press and published by NDU Press. This book was released on 2010-09 with total page 529 pages. Available in PDF, EPUB and Kindle. Book excerpt: Includes a foreword by Major General David A. Rubenstein. From the editor: "71F, or "71 Foxtrot," is the AOC (area of concentration) code assigned by the U.S. Army to the specialty of Research Psychology. Qualifying as an Army research psychologist requires, first of all, a Ph.D. from a research (not clinical) intensive graduate psychology program. Due to their advanced education, research psychologists receive a direct commission as Army officers in the Medical Service Corps at the rank of captain. In terms of numbers, the 71F AOC is a small one, with only 25 to 30 officers serving in any given year. However, the 71F impact is much bigger than this small cadre suggests. Army research psychologists apply their extensive training and expertise in the science of psychology and social behavior toward understanding, preserving, and enhancing the health, well being, morale, and performance of Soldiers and military families. As is clear throughout the pages of this book, they do this in many ways and in many areas, but always with a scientific approach. This is the 71F advantage: applying the science of psychology to understand the human dimension, and developing programs, policies, and products to benefit the person in military operations. This book grew out of the April 2008 biennial conference of U.S. Army Research Psychologists, held in Bethesda, Maryland. This meeting was to be my last as Consultant to the Surgeon General for Research Psychology, and I thought it would be a good idea to publish proceedings, which had not been done before. As Consultant, I'd often wished for such a document to help explain to people what it is that Army Research Psychologists "do for a living." In addition to our core group of 71Fs, at the Bethesda 2008 meeting we had several brand-new members, and a number of distinguished retirees, the "grey-beards" of the 71F clan. Together with longtime 71F colleagues Ross Pastel and Mark Vaitkus, I also saw an unusual opportunity to capture some of the history of the Army Research Psychology specialty while providing a representative sample of current 71F research and activities. It seemed to us especially important to do this at a time when the operational demands on the Army and the total force were reaching unprecedented levels, with no sign of easing, and with the Army in turn relying more heavily on research psychology to inform its programs for protecting the health, well being, and performance of Soldiers and their families."

Available in PDF, EPUB and Kindle. Book excerpt: In this volume, leading international investigators provide an objective view of the physiological and behavorial effects of coffee and its relationship to various diseases, including cancer. The book begins with a survey of coffee consumption and analyses of the composition of coffee, the metabolism of caffeine and other components of coffee, and the mechanism of action of caffeine. The contributors then review and assess the experimental, clinical, and epidemiological datat on the cardiovascular effects of caffeine; its role in myocardial infarction and other cardiovascular diseases; its psychopharmacology and influence on sleep, wakefulness, and cognitive function; its reproductive effects and hazards; and its carcinogenic and mutagenic potential.
