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.

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.

The physiological or psychological stresses that employees bring to their workplace affect not only their own performance but that of their co-workers and others. These stresses are often compounded by those of the job itself. Medical personnel, firefighters, police, and military personnel in combat settingsâ€"among othersâ€"experience highly unpredictable timing and types of stressors. This book reviews and comments on the performance-enhancing potential of specific food components. It reflects the views of military and non-military scientists from such fields as neuroscience, nutrition, physiology, various medical specialties, and performance psychology on the most up-to-date research available on physical and mental performance enhancement in stressful conditions. Although placed within the context of military tasks, the volume will have wide-reaching implications for individuals in any job setting.

The activities of the Food and Nutrition Board's Committee on Military Nutrition Research (CMNR, the committee) have been supported since 1994 by grant DAMD17-94-J-4046 from the U.S. Army Medical Research and Materiel Command (USAMRMC). This report fulfills the final reporting requirement of the grant, and presents a summary of activities for the grant period from December 1, 1994 through May 31, 1999. During this grant period, the CMNR has met from three to six times each year in response to issues that are brought to the committee through the Military Nutrition and Biochemistry Division of the U.S. Army Research Institute of Environmental Medicine at Natick, Massachusetts, and the Military Operational Medicine Program of USAMRMC at Fort Detrick, Maryland. The CMNR has submitted five workshop reports (plus two preliminary reports), including one that is a joint project with the Subcommittee on Body Composition, Nutrition, and Health of Military Women; three letter reports, and one brief report, all with recommendations, to the Commander, U.S. Army Medical Research and Materiel Command, since September 1995 and has a brief report currently in preparation. These reports are summarized in the following activity report with synopses of additional topics for which reports were deferred pending completion of military research in progress. This activity report includes as appendixes the conclusions and recommendations from the nine reports and has been prepared in a fashion to allow rapid access to committee recommendations on the topics covered over the time period.

Author Reveals The Truth About CaffeineAuthor Marina Kushner explores history of caffeine and its effects NEW YORK, NY -- Marina Kushner, founder of the Caffeine Awareness Alliance, in her new book "The Truth About Caffeine-How Companies That Promote it Deceive Us And What We Can Do About It" reveals frightening evidence of the damage caffeine can cause over time. As the sponsor of National Caffeine Awareness Month, recognized in March via events staged across the country, Ms. Kushner is an authority on caffeine and the detrimental effects it has on the body and mind. The Truth About Caffeine, published by SCR Publications, explores the historical and social impact of the drug throughout the ages while offering healthy alternatives to its usage. ?Caffeine has been linked to serious health problems, as well as productivity issues,? says Kushner from her Brooklyn, New York home. ?We realize the importance of having healthy citizens, and how the effects of caffeine can hurt a person?s overall health and well-being.? Caffeine overdoses can lead to headaches, jitteriness, irritability, difficulties in concentration, and mood swings which drain productivity from business and industry. In addition, caffeine consumption is linked to heart disease, pancreas and bladder cancer, hypoglycemia and central nervous system disorders.Caffeine intoxication can produce mood swings and insomnia, increased muscle tension, impair digestion and nutrition, restrict blood circulation to the brain, raise blood pressure and accelerate the heart rate. Death can result in as little as 5 grams of caffeine. "The Truth About Caffeine" features numerous clinical studies by respected medical journals and healthy alternatives to caffeinated beverages..ABOUT THE AUTHOR:Marina Kushner is the founder of the Caffeine Awareness Alliance, the first non-profit organization dedicated solely to educating consumers about the dangers of caffeine intoxication. She is a reformed coffee drinker, leading investigative journalist and speaker.

“You’ll never think the same way about your morning cup of coffee.”—Mark McClusky, editor in chief of Wired.com and author of Faster, Higher, Stronger Journalist Murray Carpenter has been under the influence of a drug for nearly three decades. And he’s in good company, because chances are you’re hooked, too. Humans have used caffeine for thousands of years. A bitter white powder in its most essential form, a tablespoon of it would kill even the most habituated user. This addictive, largely unregulated substance is everywhere—in places you’d expect (like coffee and chocolate) and places you wouldn’t (like chewing gum and fruit juice), and Carpenter reveals its impact on soldiers, athletes, and even children. It can make you stronger, faster, and more alert, but it’s not perfect, and its role in health concerns like obesity and anxiety will surprise you. Making stops at the coffee farms of central Guatemala, a synthetic caffeine factory in China, and an energy shot bottler in New Jersey, among numerous other locales around the globe, Caffeinated exposes the high-stakes but murky world of caffeine, drawing on cutting-edge science and larger-than-life characters to offer an unprecedented understanding of America’s favorite drug.
