Book Description
This book shows how vitamin A deficiency – before the vitamin was known to scientists – affected millions of people throughout history. It is a story of sailors and soldiers, penniless mothers, orphaned infants, and young children left susceptible to blindness and fatal infections. We also glimpse the fortunate ones who, with ample vitamin A-rich food, escaped this elusive stalker. Why were people going blind and dying? To unravel this puzzle, scientists around the world competed over the course of a century. Their persistent efforts led to the identification of vitamin A and its essential role in health. As a primary focus of today’s international public health efforts, vitamin A has saved hundreds of thousands of lives. But, we discover, they could save many more were it not for obstacles erected by political and ideological zealots who lack a historical perspective of the problem. Although exhaustively researched and documented, this book is written for intellectually curious lay readers as well as for specialists. Public health professionals, nutritionists, and historians of science and medicine have much to learn from this book about the cultural and scientific origins of their disciplines. Likewise, readers interested in military and cultural history will learn about the interaction of health, society, science, and politics. The author’s presentation of vitamin A deficiency is likely to become a classic case study of health disparities in the past as well as the present.

Book Description
This volume is the newest release in the authoritative series issued by the National Academy of Sciences on dietary reference intakes (DRIs). This series provides recommended intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for individuals based on age and gender. In addition, a new reference intake, the Tolerable Upper Intake Level (UL), has also been established to assist an individual in knowing how much is "too much" of a nutrient. Based on the Institute of Medicine's review of the scientific literature regarding dietary micronutrients, recommendations have been formulated regarding vitamins A and K, iron, iodine, chromium, copper, manganese, molybdenum, zinc, and other potentially beneficial trace elements such as boron to determine the roles, if any, they play in health. The book also: Reviews selected components of food that may influence the bioavailability of these compounds. Develops estimates of dietary intake of these compounds that are compatible with good nutrition throughout the life span and that may decrease risk of chronic disease where data indicate they play a role. Determines Tolerable Upper Intake levels for each nutrient reviewed where adequate scientific data are available in specific population subgroups. Identifies research needed to improve knowledge of the role of these micronutrients in human health. This book will be important to professionals in nutrition research and education.

Book Description
Carotenoids as Colorants and Vitamin A Precursors: Technological and Nutritional Applications presents the application of carotenoids to food and to the feed of animals, poultry, fish, and birds. This book discusses the use of carotenoids in medicine, in the coloring of cosmetic and pharmaceutical products, and their unique role as photoconductors. Organized into 10 chapters, this book begins with an overview of the growing preference for natural-type colors in countries around the world. This text then examines the potential level of use of various carotenoids in a variety of foods. Other chapters consider the types of carotenoids that are added to the diet of aquatic animals, which should be selected according to the species because of varying biosynthetic capabilities and expected final pigment content. This book discusses as well the mechanisms that control the assimilation and absorption of some carotenoids. The final chapter deals with determination of vitamin A value. This book is a valuable resource for industrial chemists and aquaculturists.

Book Description
Vitamin A is an essential fat-soluble vitamin with a myriad of functions including cell differentiation, redox homeostasis, growth and immune functions. Systemic inflammation has been linked with oxidative stress and has been also associated with reduced serum concentrations of Vitamin A. This book examines the protective effect of Vitamin A on lung function and cancer, chronic obstructive pulmonary disease, and coronary heart disease. Also discussed is Vitamin A and its natural derivatives, the retinoids, which participate in several biological events necessary to the maintenance of tissue homeostasis, cell cycle regulation and cell differentiation and apoptosis.

Book Description
Micronutrient malnutrition affects approximately 2 billion people worldwide. The adverse effects of micronutrient deficiencies are profound and include premature death, poor health, blindness, growth stunting, mental retardation, learning disabilities, and low work capacity. Preventing Micronutrient Deficiencies provides a conceptual framework based on past experience that will allow funders to tailor programs to existing regional/country capabilities and to incorporate within these programs the capacity to address multiple strategies (i.e., supplementation/fortification/food-based approaches/public health measures) and multiple micronutrient deficiencies. The book does not offer recommendations on how to alleviate specific micronutrient deficienciesâ€"such recommendations are already available through the publications of diverse organizations, including the U.S. Agency for International Development, the Micronutrient Initiative, World Bank, United Nations Childrens' Fund, and the World Health Organization. Instead, this volume examines key elements in the design and implementation of micronutrient interventions, including such issues as: The importance of iron, vitamin A, and iodine to health. Populations at risk for micronutrient deficiency. Options for successful interventions and their cost. The feasibility of involving societal sectors in the planning and implementation of interventions. Characteristics of successful interventions. The book also contains three in-depth background papers that address the prevention of deficiencies of iron, vitamin A, and iodine.

Book Description
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.
