An interplay between the diet and the microbiota appears to regulate the host responses. It is now well acknowledged that the microbiota and their metabolites such as short chain fatty acids, bile acids, etc modulates the metabolic status, educates the host’s intestinal immune system, and protects the host against invading pathogens and injury. Concomitantly, environmental factors such as diets and dietary components play a major role in shaping the microbiota, thereby modulating the host immune and epithelial responses, and ultimately directing the individual’s health status. Disruption in any of these elements or their interactions have been linked to the development and progression of a wide range of conditions including Inflammatory bowel disease (IBD), irritable bowel syndrome (IBS), colorectal cancer, obesity, Parkinson’s disease, autism, asthma etc. While westernised diets (rich in fat/sugar and low in fibres) and dietary additives (e.g. emulsifiers) have been identified as risk factors for these disorders, other diets such as Mediterranean, Ketogenic and probiotics and prebiotics can serve as treatment strategies due to their impact on the microbiota and possibly the host.

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.

[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.]

This book provides a comprehensive overview of metabonomics and gut microbiota research from molecular analysis to population-based global health considerations. The topics include the discussion of the applications in relation to metabonomics and gut microbiota in nutritional research, in health and disease and a review of future therapeutical, nutraceutical and clinical applications. It also examines the translatability of systems biology approaches into applied clinical research and to patient health and nutrition. The rise in multifactorial disorders, the lack of understanding of the molecular processes at play and the needs for disease prediction in asymptomatic conditions are some of the many questions that system biology approaches are well suited to address. Achieving this goal lies in our ability to model and understand the complex web of interactions between genetics, metabolism, environmental factors and gut microbiota. Being the most densely populated microbial ecosystem on earth, gut microbiota co-evolved as a key component of human biology, essentially extending the physiological definition of humans. Major advances in microbiome research have shown that the contribution of the intestinal microbiota to the overall health status of the host has been so far underestimated. Human host gut microbial interaction is one of the most significant human health considerations of the present day with relevance for both prevention of disease via microbiota-oriented environmental protection as well as strategies for new therapeutic approaches using microbiota as targets and/or biomarkers. In many aspects, humans are not a complete and fully healthy organism without their appropriate microbiological components. Increasingly, scientific evidence identifies gut microbiota as a key biological interface between human genetics and environmental conditions encompassing nutrition. Microbiota dysbiosis or variation in metabolic activity has been associated with metabolic deregulation (e.g. obesity, inflammatory bowel disease), disease risk factor (e.g. coronary heart disease) and even the aetiology of various pathologies (e.g. autism, cancer), although causal role into impaired metabolism still needs to be established. Metabonomics and Gut Microbiota in Nutrition and Disease serves as a handbook for postgraduate students, researchers in life sciences or health sciences, scientists in academic and industrial environments working in application areas as diverse as health, disease, nutrition, microbial research and human clinical medicine.

“In Missing Microbes, Martin Blaser sounds [an] alarm. He patiently and thoroughly builds a compelling case that the threat of antibiotic overuse goes far beyond resistant infections.”—Nature Renowned microbiologist Dr. Martin J. Blaser invites us into the wilds of the human microbiome, where for hundreds of thousands of years bacterial and human cells have existed in a peaceful symbiosis that is responsible for the equilibrium and health of our bodies. Now this invisible Eden is under assault from our overreliance on medical advances including antibiotics and caesarian sections, threatening the extinction of our irreplaceable microbes and leading to severe health consequences. Taking us into the lab to recount his groundbreaking studies, Blaser not only provides elegant support for his theory, he guides us to what we can do to avoid even more catastrophic health problems in the future. “Missing Microbes is science writing at its very best—crisply argued and beautifully written, with stunning insights about the human microbiome and workable solutions to an urgent global crisis.”—David M. Oshinsky, author of the Pulitzer Prize-winning Polio: An American Story

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.

Vertebrates are associated with trillions of bacteria, with the densest populations residing in the large intestine. The symbiosis between vertebrates and their gut microbiota has resulted in important implications of the gut microbiome on host health. Diet is an important factor that shapes gut microbiota composition, and because of the interplay between host-microbiome-diet, dietary strategies that modulate gut microbiome structure are deemed a relevant tool to improve host health. However, gaps in knowledge exist with respect to these interactions, and it is essential to obtain a mechanistic understanding of how these relations take place to develop successful therapeutic strategies that target the gut microbiome. In order to address these gaps, human trials were performed to assess the impact of primary components of the human diet, resistant starches and whole grains, on the gut microbiota. Overall, the impact of diet was temporal and varied across subjects. Resistant starches substantially modulated the gut bacterial community of the subject population, especially increasing the abundance of Bifidobacterium adolescentis . Ruminococcus bromii , Eubacterium rectale , and Parabacteroides distasonis were also significantly enriched. Dietary incorporation of whole grains increased the proportions of Eubacterium rectale and acetogens such as Blautia wexlerae . Of note, whole grains significantly improved inflammation and glycemic parameters. The shifts in Eubacterium rectale correlated with glycemic improvements. Moreover, distinct abundances of Dialister were determined among subjects that differed in terms of their inflammatory improvement. To gain mechanistic insight on the host-microbe-diet interplay, animal experiments were conducted to evaluate the effects of grain sorghum lipids and plant sterol esters in the context of dyslipidemia. Significant and consistent alterations in gut microbiota composition were detected in both experiments, especially involving shifts in Coriobacteriaceae and Erysipelotrichaceae abundance, which displayed remarkable correlations to host cholesterol markers. Mathematical modeling of these associations revealed them to be inhibitory interactions, suggesting that changes in host metabolism affected gut microbiome structure through an antimicrobial effect of cholesterol, which was conformed in vitro against selected gut microbes. In conclusion, the studies presented in this dissertation allowed new insights on the impact of diet on the gut microbiota and its consequences for health.

Microbial endocrinology represents a newly emerging interdisciplinary field that is formed by the intersection of the fields of neurobiology and microbiology. This book will introduce a new perspective to the current understanding not only of the factors that mediate the ability of microbes to cause disease, but also to the mechanisms that maintain normal homeostasis. The discovery that microbes can directly respond to neuroendocrine hormones, as evidenced by increased growth and production of virulence-associated factors, provides for a new framework with which to investigate how microorganisms interface not only with vertebrates, but also with invertebrates and even plants. The reader will learn that the neuroendocrine hormones that one most commonly associates with mammals are actually found throughout the plant, insect and microbial communities to an extent that will undoubtedly surprise many, and most importantly, how interactions between microbes and neuroendocrine hormones can influence the pathophysiology of infectious disease.

This work sheds new light on the interplay between the gut, gut microbiota, and host physiological processes in production animals. The gut microbiome shapes health and susceptibility to disease and has become a leading area of research in the animal sciences. Gut health encompasses a number of physiological and functional features. Nutrient digestion and absorption, host metabolism and energy generation, a stable microbiome, mucus layer development, barrier function, and mucosal immune responses; all of which are required to interact to make an animal perform physiologically and according to its greatest genetic potential. This carefully presented book broadens our vision, approach and results on gut health and the ability to regulate animal production. Understanding the chemistry of microbiomes has broad implications, including providing functional annotations for the microbial genomes, insights into the chemical languages that link microbes to each other and to their host, and translational implications for precision veterinary medicine, environmental health, and sustainable animal agriculture and welfare. Experts working in microbiome research, host immunity, and animal production, veterinarians and researchers in livestock science will understand the great importance of this volume.
