The Gut Microbiome In Health And Disease

The book provides an overview on how the gut microbiome contributes to human health. The readers will get profound knowledge on the connection between intestinal microbiota and immune defense systems. The tools of choice to study the ecology of these highly-specialized microorganism communities such as high-throughput sequencing and metagenomic mining will be presented. In addition the most common diseases associated to the composition of the gut flora are discussed in detail. The book will address researchers, clinicians and advanced students working in biomedicine, microbiology and immunology.

This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area!

Human Gut Microbiota in Health and Disease: From Pathogenesis to Therapy is a comprehensive discussion on all the aspects associated with the early colonization of gut microbiota, its development and maintenance, and its symbiotic relationship with the host in promoting health. Chapters illustrate the complex mechanisms and metabolic signaling pathways related to how the gut microbiota maintain proper regulation of glucose, lipid and energy homeostasis and immune response, all while mediating inflammatory processes involved in the etiology of many chronic disease conditions. With today's common use of pharmaceutical medicine in treating symptoms and frequent overuse of antibiotics in chronic disease within mainstream medical practice, our understanding of the etiological mechanisms of dysbiosis-induced chronic disease and natural approaches to prevention and potential cures for these diseases is of vital importance to overall human health. Details the complex relationship between human microbiota in the gut, oral cavity and skin as well as their colonization, development and impact of factors that influence the relationship Illustrates the mechanisms associated with dysbiosis-associated inflammation and its role in the onset and progression in chronic disease Provides the primary mechanisms and comprehensive scientific evidence for the use of dietary modification and pro- and prebiotics in preventing chronic disease

This book provides a comprehensive examination of the role of gut microbiome/microflora in nutrition, metabolism, disease prevention and health issues, including farm animal health and food value, and human gastrointestinal health and immunity. Indigenous microbiotas, particularly the gut microflora/microbiome, are an essential component in the modern concept of human and animal health. The diet and lifestyle of the host and environment have direct impact on gut microflora and the patterns of gut microbial colonization associated with health and diseases have been documented. Contributing authors cover the impact of gut microbiome in farm animal health, and explore the possibility of modulating the human gut microbiome with better animal products to prevent human diseases, including endemic and emerging diseases such as obesity, cancer and cardiac diseases. Dieting plan and control methods are examined, with attention paid to balance dieting with natural food and drink components. In addition, the role of gut microbiota in enteric microbial colonization and infections in farm animals is also discussed. The volume also explores the possibility of improving human health by modulating the microbiome with better food, including bio-active foods and appropriate forms of intake. Throughout the chapters, authors examine cutting edge research and technology, as well as future directions for better practices regarding emerging issues, such as the safety and production of organic food.

The Food Forum convened a public workshop on February 22-23, 2012, to explore current and emerging knowledge of the human microbiome, its role in human health, its interaction with the diet, and the translation of new research findings into tools and products that improve the nutritional quality of the food supply. The Human Microbiome, Diet, and Health: Workshop Summary summarizes the presentations and discussions that took place during the workshop. Over the two day workshop, several themes covered included: The microbiome is integral to human physiology, health, and disease. The microbiome is arguably the most intimate connection that humans have with their external environment, mostly through diet. Given the emerging nature of research on the microbiome, some important methodology issues might still have to be resolved with respect to undersampling and a lack of causal and mechanistic studies. Dietary interventions intended to have an impact on host biology via their impact on the microbiome are being developed, and the market for these products is seeing tremendous success. However, the current regulatory framework poses challenges to industry interest and investment.

This accessibly written, comprehensive summary of research findings on the gut microbiome and its implications for health and disease--a topic of growing interest and concern--serves as an essential resource for teachers and students. Most people know that the digestive tract contains billions of helpful gut bacteria, but how does the gut microbiome affect our health? What exactly do these bacteria do, and what are the negative effects when these microorganisms are harmed by what we eat and do? What impacts might they have on conditions such as irritable bowel syndrome (IBS), obesity, and autism? This book provides an accessible, holistic introduction to the study of the human gut microbiome and its effects on digestion and disease--one of the newest and most rapidly expanding fields in medicine today. The gut microbiome is known as "the forgotten organ" because it is not identified as part of the human body per se, yet it has an immense influence on many systems in the body. The Gut Microbiome: Exploring the Connection between Microbes, Diet, and Health explains what the microbiome is, the many functions it serves, how it can be either harmed or supported by our actions, and the role it may play in various diseases and in determining our overall health. The book examines the various potential causes of imbalance in the microbiome, such as diet and other lifestyle factors, and then identifies strategies for improving human health by protecting the gut microbiota. The science-based information is detailed but accessible to general readers or students without extensive background knowledge.

[Increasing evidence suggests that microbiota and especially the gut microbiota (the microbes inhabiting the gut including bacteria, archaea, viruses, and fungi) plays a key role in human physiology and pathology. Recent findings indicate how dysbiosis—an imbalance in the composition and organization of microbial populations—could severely impact the development of different medical conditions (from metabolic to mood disorders), providing new insights into the comprehension of diverse diseases, such as IBD, obesity, asthma, autism, stroke, diabetes, and cancer. Given that microbial cells in the gut outnumber host cells, microbiota influences human physiology both functionally and structurally. Microbial metabolites bridge various—even distant—areas of the organism by way of the immune and hormone system. For instance, it is now clear that the mutual interaction between the gastrointestinal tract and the brain (gut–brain axis), often involves gut microbiota, indicating that the crosstalk between the organism and its microbial residents represents a fundamental aspect of both the establishment and maintenance of healthy conditions. Moreover, it is crucial to recognize that beyond the intestinal tract, microbiota populates other host organs and tissues (e.g., skin and oral mucosa). We have edited this eBook with the aim of publishing manuscripts focusing on the impact of microbiota in the development of different diseases and their associated treatments.]
