Download or read book The Human Microbiome Diet and Health written by Food Forum and published by National Academies Press. This book was released on 2013-02-27 with total page 197 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book The Chemistry of Microbiomes written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2017-07-19 with total page 133 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21st century has witnessed a complete revolution in the understanding and description of bacteria in eco- systems and microbial assemblages, and how they are regulated by complex interactions among microbes, hosts, and environments. The human organism is no longer considered a monolithic assembly of tissues, but is instead a true ecosystem composed of human cells, bacteria, fungi, algae, and viruses. As such, humans are not unlike other complex ecosystems containing microbial assemblages observed in the marine and earth environments. They all share a basic functional principle: Chemical communication is the universal language that allows such groups to properly function together. These chemical networks regulate interactions like metabolic exchange, antibiosis and symbiosis, and communication. The National Academies of Sciences, Engineering, and Medicine's Chemical Sciences Roundtable organized a series of four seminars in the autumn of 2016 to explore the current advances, opportunities, and challenges toward unveiling this "chemical dark matter" and its role in the regulation and function of different ecosystems. The first three focused on specific ecosystemsâ€"earth, marine, and humanâ€"and the last on all microbiome systems. This publication summarizes the presentations and discussions from the seminars.
Download or read book Dietary Polyphenols written by Francisco A . Tomás-Barberán and published by John Wiley & Sons. This book was released on 2020-12-15 with total page 560 pages. Available in PDF, EPUB and Kindle. Book excerpt: Presents recent research on metabolism and the health effects of polyphenols Consumer interest in the health benefits of many phenolic compounds found in plant foods and derivatives has grown considerably in recent years, giving rise to an increased demand for functional foods. Although preclinical and observational studies have promoted the protective properties of polyphenols for a range of chronic diseases, evidence has shown that most dietary polyphenols have little bioavailability. Once ingested, most of them are metabolized by either the intestinal enzymes or by the gut microbiota and then undergo extensive phase-II metabolism reaching significant concentrations of conjugated metabolites. They remain in the systemic circulation and target systemic tissues where trigger biological effects. The polyphenol-derived metabolites produced in humans are dependent upon the composition of the gut microbiota and the subject genetics. Thus all the metabolites do not show the same biological activity in different individuals. To fully understand the health effects of polyphenols, further clinical investigations are required. Dietary Polyphenols describes the latest findings on the polyphenol metabolism and reviews the current evidence on their health effects and that of their bioavailable metabolites. Emphasizing the importance of interindividual variability and the critical role of gut microbiota, this authoritative volume features contributions from recognized experts in the field, exploring specific families of extractable and non-extractable phenolic compounds that exhibit potential health effects. Topics include structural diversity of polyphenols and distribution in foods, bioavailability and bioaccessibility of phenolics, metabolism, and gastrointestinal absorption of various metabolites and their health effects. This comprehensive volume: Discusses the bioavailability, bioaccessibility, pharmacokinetics studies, and microbial metabolism of different groups of phenolic compounds Examines the interaction between polyphenols and gut microbiota Describes analytical methods for identifying and quantifying polyphenols in foods and biological samples Reviews recent epidemiological and clinical intervention studies showing protective effects of polyphenols Dietary Polyphenols: Metabolism and Health Effects is an important resource for scientists working in the area of dietary polyphenols and health effects, microbiota, and their interaction with other nutritional compounds, and for health professionals, nutritionists, dieticians, and clinical researchers with interest in the role of polyphenols in the prevention and treatment of chronic diseases.
Download or read book Metabolism of Alimentary Compounds by the Intestinal Microbiota and Health written by François Blachier and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of the metabolism of dietary compounds by the intestinal microbiota, and on the consequences of such metabolic activity on host metabolism and physiological functions; both in intestinal and peripheral tissues. Over the last years, our understanding of the causal links between microbiota metabolic activity towards dietary and endogenous substrates and human health status has evolved extensively. In this context, the book starts with a comprehensive introduction devoted to the physiological and metabolic functions of the intestinal epithelium, followed by a part dedicated to the way intestine offers board and lodging for microbes being on a short- or long-term stay. The next chapters focus on the utilization of the available substrates from diet by the intestinal bacteria to produce numerous bacterial metabolites, and on the impact of such microbial activity, in the first place for communication between microbes, and for communication between microbes and lodging host. As will be detailed, this latter process of interkingdom communication leads to either beneficial or deleterious effects on intestinal physiology and metabolism. Special attention is given to selected pathophysiological processes namely chronic intestinal inflammation, colorectal carcinogenesis, and diarrhea. Then, the effects of modifications of bacterial metabolites and other bioactive compounds by the host after intestinal absorption, and consequences for peripheral tissue functions are presented. Summarizing the state of the art on what is known about the metabolic crosstalk between gut microbiota and human metabolism, as well as perspectives for further experimental and clinical research, this book provides a useful resource for researchers, professionals, and students with a background in biology, and/or nutrition, medicine, pharmacology, and for those which are involved in the agriculture and food production. By explaining technical terms all along the text, this book should be understandable also for interested non-specialists.

Download or read book The Impact of Food Bioactives on Health written by Kitty Verhoeckx and published by Springer. This book was released on 2015-04-29 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Infogest” (Improving Health Properties of Food by Sharing our Knowledge on the Digestive Process) is an EU COST action/network in the domain of Food and Agriculture that will last for 4 years from April 4, 2011. Infogest aims at building an open international network of institutes undertaking multidisciplinary basic research on food digestion gathering scientists from different origins (food scientists, gut physiologists, nutritionists...). The network gathers 70 partners from academia, corresponding to a total of 29 countries. The three main scientific goals are: Identify the beneficial food components released in the gut during digestion; Support the effect of beneficial food components on human health; Promote harmonization of currently used digestion models Infogest meetings highlighted the need for a publication that would provide researchers with an insight into the advantages and disadvantages associated with the use of respective in vitro and ex vivo assays to evaluate the effects of foods and food bioactives on health. Such assays are particularly important in situations where a large number of foods/bioactives need to be screened rapidly and in a cost effective manner in order to ultimately identify lead foods/bioactives that can be the subject of in vivo assays. The book is an asset to researchers wishing to study the health benefits of their foods and food bioactives of interest and highlights which in vitro/ex vivo assays are of greatest relevance to their goals, what sort of outputs/data can be generated and, as noted above, highlight the strengths and weaknesses of the various assays. It is also an important resource for undergraduate students in the ‘food and health’ arena.

Download or read book Hormones and Resistance written by Hans Selye and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 1158 pages. Available in PDF, EPUB and Kindle. Book excerpt: 7 If so, the individual members of each class thus identified could then be subjected to a more profound pharmacokinetic analysis. In other words, we had to determine first which hormone protects against which drug, before we could explore how it did this. We had to know first that a hormone has adaptive value before we could ask whether this is due to a syntoxic or a catatoxic mechanism. Such observations, as the fact that an indomethacin-induced intestinal ulcer can be prevented by ethylestrenol, orthat cortisol aggravates certain infections, reveal nothing about how these hormones work; but only findings of this type can tell us where further research would be rewarding. Of course, scientists can rarely identify by direct observation the tbings that they are looking for; most of the time they have to be guided by indirect indices. The ebernist often first detects a compound, or even a particular functional group in its molecule, by inference from a color reaction, a revealing X-ray diffraction pattern or the formation of a characteristic precipitate. The physician must first suspect the presence of a microbe through certain clinical signs and symptoms before he can verify his diagnosis by looking for a particular organism. It is perhaps not too daring to hope that in our first efforts to clarify the role of hormones in resistance, simple, directly visible indicators might also serve us best.

Download or read book Diet Microbe Interactions in the Gut written by Kieran Tuohy and published by Academic Press. This book was released on 2014-08-04 with total page 268 pages. Available in PDF, EPUB and Kindle. Book excerpt: Drawing on expert opinions from the fields of nutrition, gut microbiology, mammalian physiology, and immunology, Diet-Microbe Interactions for Human Health investigates the evidence for a unified disease mechanism working through the gut and its resident microbiota, and linking many inflammation-related chronic diet associated diseases. State of the art post-genomic studies can highlight the important role played by our resident intestinal microbiota in determining human health and disease. Many chronic human diseases associated with modern lifestyles and diets — including those localized to the intestinal tract like inflammatory bowel disease and celiac disease, and more pervasive systemic conditions such as obesity, diabetes and cardiovascular disease — are characterized by aberrant profiles of gut bacteria or their metabolites. Many of these diseases have an inflammatory basis, often presenting with a chronic low-grade systemic inflammation, hinting at persistent and inappropriate activation of inflammatory pathways. Through the presentation and analysis of recent nutrition studies, this book discusses the possible mechanisms underpinning the disease processes associated with these pathologies, with high fat diets appearing to predispose to disease, and biologically active plant components, mainly fiber and polyphenols, appearing to reduce the risk of chronic disease development. - One comprehensive, translational source for all aspects of nutrition and diet's effect on gastrointestinal health and disease - Experts in nutrition, diet, microbiology and immunology take readers from the bench research (cellular and biochemical mechanisms of vitamins and nutrients) to new preventive and therapeutic approaches - Clear presentations by leading researchers of the cellular mechanisms underlying diet, immune response, and gastrointestinal disease help practicing nutritionists and clinicians (gastroenterologists, endocrinologists) map out new areas for clinical research and structuring clinical recommendations
Download or read book Microbial Endocrinology written by Mark Lyte and published by Springer. This book was released on 2010-10-22 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Missing Microbes written by Martin J. Blaser, MD and published by Henry Holt and Company. This book was released on 2014-04-08 with total page 289 pages. Available in PDF, EPUB and Kindle. Book excerpt: “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
Download or read book Environmental Chemicals the Human Microbiome and Health Risk written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2018-03-01 with total page 123 pages. Available in PDF, EPUB and Kindle. Book excerpt: A great number of diverse microorganisms inhabit the human body and are collectively referred to as the human microbiome. Until recently, the role of the human microbiome in maintaining human health was not fully appreciated. Today, however, research is beginning to elucidate associations between perturbations in the human microbiome and human disease and the factors that might be responsible for the perturbations. Studies have indicated that the human microbiome could be affected by environmental chemicals or could modulate exposure to environmental chemicals. Environmental Chemicals, the Human Microbiome, and Health Risk presents a research strategy to improve our understanding of the interactions between environmental chemicals and the human microbiome and the implications of those interactions for human health risk. This report identifies barriers to such research and opportunities for collaboration, highlights key aspects of the human microbiome and its relation to health, describes potential interactions between environmental chemicals and the human microbiome, reviews the risk-assessment framework and reasons for incorporating chemicalâ€"microbiome interactions.

Download or read book Microbial Endocrinology The Microbiota Gut Brain Axis in Health and Disease written by Mark Lyte and published by Springer. This book was released on 2014-07-05 with total page 440 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of microbial endocrinology is expressly devoted to understanding the mechanisms by which the microbiota (bacteria within the microbiome) interact with the host (“us”). This interaction is a two-way street and the driving force that governs these interactions are the neuroendocrine products of both the host and the microbiota. Chapters include neuroendocrine hormone-induced changes in gene expression and microbial endocrinology and probiotics. This is the first in a series of books dedicated to understanding how bi-directional communication between host and bacteria represents the cutting edge of translational medical research, and hopefully identifies new ways to understand the mechanisms that determine health and disease.
