This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.

Every aspect of immune function and host defense is dependent upon a proper supply and balance of nutrients. Severe malnutrition can cause significant alteration in immune response, but even subclinical deficits may be associated with an impaired immune response, and an increased risk of infection. Infectious diseases have accounted for more off-duty days during major wars than combat wounds or nonbattle injuries. Combined stressors may reduce the normal ability of soldiers to resist pathogens, increase their susceptibility to biological warfare agents, and reduce the effectiveness of vaccines intended to protect them. There is also a concern with the inappropriate use of dietary supplements. This book, one of a series, examines the impact of various types of stressors and the role of specific dietary nutrients in maintaining immune function of military personnel in the field. It reviews the impact of compromised nutrition status on immune function; the interaction of health, exercise, and stress (both physical and psychological) in immune function; and the role of nutritional supplements and newer biotechnology methods reported to enhance immune function. The first part of the book contains the committee's workshop summary and evaluation of ongoing research by Army scientists on immune status in special forces troops, responses to the Army's questions, conclusions, and recommendations. The rest of the book contains papers contributed by workshop speakers, grouped under such broad topics as an introduction to what is known about immune function, the assessment of immune function, the effect of nutrition, and the relation between the many and varied stresses encountered by military personnel and their effect on health.

Vitamin E is a fat-soluble vitamin that exists in eight different forms. Each form has its own biological activity, which is the measure of potency or functional use in the body. Alpha-tocopherol (-tocopherol) is the name of the most active form of vitamin E in humans. It is also a powerful biological antioxidant. Vitamin E in supplements is usually sold as alpha-tocopheryl acetate, a form that protects its ability to function as an antioxidant. The synthetic form is labelled "D, L" while the natural form is labelled "D". The synthetic form is only half as active as the natural form. Antioxidants such as vitamin E act to protect the cells against the effects of free radicals, which are potentially damaging by-products of energy metabolism. Free radicals can damage cells and may contribute to the development of cardiovascular disease and cancer. Studies are underway to determine whether vitamin E, through its ability to limit production of free radicals, might help prevent or delay the development of those chronic diseases. Vitamin E has also been shown to play a role in immune function, in DNA repair and other metabolic processes. This new book presents leading research on this important topic.

Vitamin E is a well described and established fat-soluble essential micronutrient and as such has to be provided to the human body on a regular basis in order to avoid deficiency and maintain a healthy status. This is well established and also reviewed in a number of publications. However, a huge body of evidence has accumulated over the last decade, or so, which provides new insights on the mode of action of vitamin E, and the biological role of the tocopherol isomers, and sheds new light on the role of vitamin E in human health. Both fundamental knowledge gain and new data on the role and challenges of vitamin E as an essential micronutrient, including emerging evidence on clinical benefits, will be addressed to put this essential micronutrient in the appropriate perspective. Given this level of new evidence which has emerged over the recent years, a book on vitamin E will put into perspective the concerns which have been raised on vitamin E and which resulted in a misinformation and confusion of the public regarding the importance of vitamin E for human health. This book will reemphasize that Vitamin E is clearly required for human health and its inadequacy leads to increased risk of a variety of diseases. In addition new data of non-communicable diseases (NCD) dependent on vitamin E status show that a lifetime of low intake increases risks of development, severity and complications of NCDs. This text will put the vitamin E case into an up-to-date, science based, applicable real-life perspective and offer pragmatic solutions for its safe and personalized use beyond the various methodological and statistical controversies. The purpose of this book is also to raise awareness not only in the nutrition and medical community, but also in the public media that there are a number of health conditions where an increased intake of vitamin E can be of potential importance. Further this review should also stimulate funding organizations and agencies to increase their support for vitamin E research in order to facilitate the further exploration of the safe and efficacious use of this essential micronutrient.

Vitamin E is a group of fat-soluble compounds found in a wide variety of foods. Daily requirements of vitamin E can be met with a balanced diet. High-dose supplementation may be hazardous rather than beneficial. Vitamin E serves as an antioxidant, participates in anti-inflammatory processes, inhibits platelet aggregation, and enhances immunity. Vitamin E supplementation can be beneficial against coronary artery disease, eye disorders, cognitive decline, cancer, and skin aging. This book will mainly focus on the diverse functions of vitamin E, importance of vitamin E status to provide a healthy lifespan, and the interaction between vitamin E and several pathological conditions. Readers will receive a general overview of the importance of vitamin E in health and different pathological conditions.

Vitamin E was discovered in 1922 by Evans and Bishop as an essential micronutrient for reproduction in rats. The active substance was isolated in 1936 by Evans and was named tocopherol, although the tocopherols and tocotrienols are actually a group of eight isomeric molecules that are characterized by a chromanol ring structure and a side chain. Providing an overview of the state-of-the-art of the chemistry of vitamin E, this book reflects the issues stemming from the complexity of the role and actions in vivo as well as in vitro. It summarizes information on the properties and function of vitamin E, the current understanding of the advantages and limitations of it, and also its application in promotion of health and prevention of diseases. Based on sound, solid scientific evidence, this is a timely addition to the literature as the centennial anniversary of the discovery of this important vitamin approaches.

The world continues to lose more than a million lives each year to the HIV epidemic, and nearly two million individuals were infected with HIV in 2017 alone. The new Sustainable Development Goals, adopted by countries of the United Nations in September 2015, include a commitment to end the AIDS epidemic by 2030. Considerable emphasis on prevention of new infections and treatment of those living with HIV will be needed to make this goal achievable. With nearly 37 million people now living with HIV, it is a communicable disease that behaves like a noncommunicable disease. Nutritional management is integral to comprehensive HIV care and treatment. Improved nutritional status and weight gain can increase recovery and strength of individuals living with HIV/AIDS, improve dietary diversity and caloric intake, and improve quality of life. This book highlights evidence-based research linking nutrition and HIV and identifies research gaps to inform the development of guidelines and policies for the United Nations’ Sustainable Development Goals. A comprehensive approach that includes nutritional interventions is likely to maximize the benefit of antiretroviral therapy in preventing HIV disease progression and other adverse outcomes in HIV-infected men and women. Modification of nutritional status has been shown to enhance the quality of life of those suffering HIV/AIDS, both physically in terms of improved body mass index and immunological markers, and psychologically, by improving symptoms of depression. While the primary focus for those infected should remain on antiretroviral treatment and increasing its availability and coverage, improvement of nutritional status plays a complementary role in the management of HIV infection.

The first 90 years of vitamin E research has produced prolific and notable discoveries, but until the last few decades, attention has been given mostly to the biological activities and underlying mechanisms of alpha-tocopherol, which we now know is one of more than eight vitamin E isomers. Currently, the non-tocopherol vitamin E molecule tocotrienol has reached a new measure of research height: more than one-third of all vitamin E tocotrienol research of the last 30 years has been published since 2009. The thriving field of tocotrienol research gives ground for publication of Tocotrienols: Vitamin E Beyond Tocopherols, Second Edition, a compilation of the latest tocotrienol research in all new chapters. Highlights Established research, including prevention and treatment of cardiovascular disease, metabolic syndrome, and cancer Emergent research, including angiogenesis, bioavailability, bone health, gastric injury, inflammation, life extension, and skin health Tocopherol interference with tocotrienol functions All new chapters and many new contributors Recognized as potent antioxidants, tocotrienols play a role in cholesterol reduction, tumor suppression, reversal of arteriosclerosis, and protection of the heart against oxidative stress. Compiling contributions from leading researchers, this book overviews tocotrienols, and examines their sources, chemistry, and mechanisms of action. Contributors discuss the role of tocotrienols in the treatment and prevention of cancer and in cardiovascular health, diabetes, and other hormone regulation by tocotrienols. In addition, the book addresses animal and in vitro as well as mechanistic and pre-clinical studies. Dr. Tan discusses the benefits of tocotrienol in a YouTube video.
