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.

Nutritional Epigenomics offers a comprehensive overview of nutritional epigenomics as a mode of study, along with nutrition’s role in the epigenomic regulation of disease, health and developmental processes. Here, an expert team of international contributors introduces readers to nutritional epigenomic regulators of gene expression, our diet’s role in epigenomic regulation of disease and disease inheritance, caloric restriction and exercise as they relate to recent epigenomic findings, and the influence of nutritional epigenomics over circadian rhythms, aging and longevity, and fetal health and development, among other processes. Disease specific chapters address metabolic disease (obesity and diabetes), cancer, and neurodegeneration, among other disorders. Diet-gut microbiome interactions in the epigenomic regulation of disease are also discussed, as is the role of micronutrients and milk miRNAs in epigenetic regulation. Finally, chapter authors examine ongoing discussions of race and ethnicity in the social-epigenomic regulation of health and disease. Empowers the reader to employ nutritional epigenomics approaches in their own research Discusses the latest topics in nutritional epigenomics in the regulation of aging, circadian rhythm, inheritance and fetal development, as well as metabolism and disease Offers a full grounding in epigenetic reprogramming and nutritional intervention in the treatment and prevention of disease, as informed by population-based studies

B-vitamins are a group of water soluble vitamins that play significant roles in cell metabolism and synthesis of red blood cells. There are eight B-vitamins, namely, B1 (thiamin), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate [folic acid]), and B12 (cobalamin). Vitamin B9 and vitamin B12 are essential water-soluble vitamins that perform pivotal function in the maintenance of one-carbon metabolism. The one carbon metabolism is a set of interconnected metabolic pathways driven by folate and methionine. It generates methyl groups for use in DNA synthesis, amino acid homeostasis, antioxidant generation, and epigenetic regulation. Developmental defects, impaired cognitive function, or blocked normal blood production are some of the possible outcomes associated with a diet deficient in vitamins B9 and B12. It has been observed in certain studies that higher levels of these vitamins may lead to immune dysfunction, cancer, or increased mortality. Research in B-vitamins is now primarily focused on developing specific therapies that target one-carbon metabolism for managing cancer and immune diseases. This book includes some of the vital pieces of works being conducted across the world, on various topics related to B-vitamins and their role in human health. Students, researchers, experts and all associated with this area of study will benefit alike from this book.

Nutrition and Epigenetics presents new information on the action of diet and nutritional determinants in regulating the epigenetic control of gene expression in health and disease. Each chapter gives a unique perspective on a different nutritional or dietary component or group of components, and reveals novel mechanisms by which dietary factors modulate the epigenome and affect development processes, chronic disease, and the aging process. This pivotal text: Documents the epigenetic effect of antioxidants and their health benefits Adds to the understanding of mechanisms leading to disease susceptibility and healthy aging Illustrates that the epigenetic origins of disease occur in early (fetal) development Synthesizes the data regarding nutrient and epigenomic interactions Nutrition and Epigenetics highlights the interactions among nutrients, epigenetics, and health, providing an essential resource for scientists and clinical researchers interested in nutrition, aging, and metabolic diseases.

Molecular Basis of Nutrition and Aging: A Volume in the Molecular Nutrition Series focuses on the nutritional issues associated with aging and the important metabolic consequences of diet, nutrition, and health. The book is subdivided into four parts that reflect the impact of nutrition from a biomolecular level to individual health. In Part One, chapters explore the general aspects of aging, aging phenotypes, and relevant aspects of nutrition related to the elderly and healthy aging. Part Two includes molecular and cellular targets of nutrition in aging, with chapters exploring lipid peroxidation, inflammaging, anabolic and catabolic signaling, epigenetics, DNA damage and repair, redox homeostasis, and insulin sensitivity, among others. Part Three looks at system-level and organ targets of nutrition in aging, including a variety of tissues, systems, and diseases, such as immune function, the cardiovascular system, the brain and dementia, muscle, bone, lung, and many others. Finally, Part Four focuses on the health effects of specific dietary compounds and dietary interventions in aging, including vitamin D, retinol, curcumin, folate, iron, potassium, calcium, magnesium, zinc, copper, selenium, iodine, vitamin B, fish oil, vitamin E, resveratrol, polyphenols, vegetables, and fruit, as well as the current nutritional recommendations. Offers updated information and a perspectives on important future developments to different professionals involved in the basic and clinical research on all major nutritional aspects of aging Explores how nutritional factors are involved in the pathogenesis of aging across body systems Investigates the molecular and genetic basis of aging and cellular senescence through the lens of the rapidly evolving field of molecular nutrition

An authoritative and comprehensive review of our current knowledge of the vitamins, their metabolic functions and the scientific basis for setting recommended intakes for the prevention of deficiency and promotion of optimum health. This publication will be a valuable reference for students and specialists alike in the field of nutritional biochemistry.
