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.
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.
This book highlights the role of vitamins in preventing or reducing the pathogenesis or treatment of infectious viral diseases based on current ongoing research and past work.

Features Includes chapters from a team of leading international scholars Reviews the history and recent research on the functions, benefits, and uses of vitamin C Focuses special attention on the way vitamin C can be used in the treatment of cancers Discusses how vitamin C can be employed against infectious disease
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.
This volume provides readers with a systematic assessment of current literature on the link between nutrition and immunity. Chapters cover immunonutrition topics such as child development, cancer, aging, allergic asthma, food intolerance, obesity, and chronic critical illness. It also presents a thorough review of microflora of the gut and the essential role it plays in regulating the balance between immune tolerance and inflammation. Written by experts in the field, Nutrition and Immunity helps readers to further understand the importance of healthy dietary patterns in relation to providing immunity against disorders and offering readily available immunonutritional programming in clinical care. It will be a valuable resource for dietitians, immunologists, endocrinologists and other healthcare professionals.
Nutrigenetics: Applying the Science of Personal Nutrition provides a fully referenced, readable guide to understanding the rationale and importance of nutrigenetic applications and explains why single nutrition recommendations will not fit everybody or even a majority of modern humans. This books explains how genetic variation shapes individual nutrition requirements and sensitivities, presents questions to ask about reported gene-nutrient interactions, and what needs to be done before putting nutrigenetic tests to practical use. This book blends key concepts from the fields of genetics, biochemistry, epidemiology, public health, and clinical medicine to give a rich perspective on the genetically diverse nutritional needs and sensitivities of individuals in health and disease. A steadily increasing number of people order genetic tests to find out what they should eat for better health, well being and performance, and an even greater number asks their healthcare providers about such tests. Most of the currently offered tests are not grounded in current knowledge, often absurdly so, but few professionals can explain why they are misguided. On the other hand, there are more evidence-supported genetic variants that can guide nutrition decisions, but again most healthcare providers know little about them, much less use them in their daily practice. There is a great need for a solidly evidence-based yet accessible book that explains the science of nutrigenetics and provides the tools to evaluate new nutrigenetic tests. - Comprehensive coverage of the emerging science of nutritional genetics and its promise for individually tailored nutrition guidance - Presents practical examples to enhance comprehension and spur additional research - Offers a logical progression from what nutrigenetics is, to its possibilities in enhancing health
Both nutrition deficiency and overnutrition can have a significant effect on the risk of infection. Nutrition, Immunity, and Infection focuses on the influence of diet on the immune system and how altering one’s diet helps prevent and treat infections and chronic diseases. This book reviews basic immunology and discusses changes in immune function throughout the life course. It features comprehensive chapters on obesity and the role of immune cells in adipose tissue; undernutrition and malnutrition; infant immune maturation; pre- and probiotics; mechanisms of immune regulation by various vitamins and minerals; nutrition and the aging immune system; nutrition interactions with environmental stress; and immunity in the global health arena. Nutrition, Immunity, and Infection describes the various roles of nutrients and other food constituents on immune function, host defense, and resistance to infection. It describes the impact of infection on nutritional status through a translational approach. Chapters bring together molecular, cellular, and experimental studies alongside human trials so that readers can assess both the evidence for the effects of the food component being discussed and the mechanisms underlying those effects. The impact of specific conditions including obesity, anorexia nervosa, and HIV infection is also considered. Chapter authors are experts in nutrition, immunity, and infection from all around the globe, including Europe, Australia, Brazil, India, and the United States. This book is a valuable resource for nutrition scientists, food scientists, dietitians, health practitioners, and students interested in nutrition and immunity.
