Gut microbiota plays an important role in host health maintenance and disease pathogenesis. The development of a stable and diverse gut microbiota is essential to various host physiologic functions such as immunoregulation, pathogen prevention, energy harvest, and metabolism. At the same time, a dysbiotic gut microbiota associated with disease is altered in structure and function, and often characterized by a decrease in species richness and proliferation of pathogenic bacterial taxa. As a shared substrate between the host and the gut microbiota, diet significantly impacts the health and disease states of the host both directly and through gut microbial metabolite production...

Epigenetics can be defined as stable, potentially heritable changes in cellular phenotype caused by mechanisms other than alterations in the underlying DNA sequence. DNA methylation is amongst the most intensely studied epigenetic mechanisms and has been shown to play a major role in regulating fundamental aspects of cell biology including cellular differentiation, organ development, and cell type-specific gene expression. Importantly, it is becoming increasingly clear that epigenetic mechanisms operate at the interface between the genetic code and our environment and are able to mediate environmental changes into stable phenotypic alterations...

The gut microbiota represents a complex and diverse ecosystem with a profound impact on human health, promoting immune maturation, and host metabolism as well as colonization resistance. Important members that have often been disregarded are the methanogenic archaea. Methanogenic archaea reduce hydrogen levels via the production of methane, thereby stimulating food fermentation by saccharolytic bacteria. On the other hand, colonization by archaea has been suggested to promote a number of gastrointestinal and metabolic diseases such as colorectal cancer, inflammatory bowel disease, and obesity...

OBJECTIVE: Maternal high-fat diet (HFD) may alter the offspring intestinal immune system, thereby enhancing susceptibility toward inflammatory bowel disease. The objective of the current study was to investigate the impact of maternal HFD on offspring intestinal health using a mouse model of dextran sulfate sodium (DSS)-induced colitis. METHODS: Dams were provided with either HFD (60%) or control diet. After weaning, female offspring from both groups were kept on 45% HFD...

Eosinophilic Oesophagitis (EoE) is one of the most common causes of reflux like symptoms and feeding problems in children and food impaction and dysphagia in adults with a prevalence of 1:2500. Therapeutic options include diet, use of swallowed corticosteroids or dilation. In the last several years, recent clinical and translational research have identified some common and distinctive features, for example, the varying response to diet and medications. As EoE shares some characteristics with both asthma and inflammatory bowel disease, the advances in these fields suggests that various phenotypes may also exist in patients with EoE...

BACKGROUND: An increasing number of studies show low diversity of the gut microbiome in those with chronic diseases such as obesity, inflammatory bowel disease, and allergy. Manipulation of the microbiota may promote health. However, the adult microbiota is stable and may be difficult to change. Understanding the fixed and modifiable factors, which determine colonization in early life, may provide strategies for acquisition of a health-promoting microbiome. SUMMARY: Not enough is known about the long-term effects of established determinants of gut colonization, including delivery mode, perinatal antibiotics, and infant diet...

We wanted to investigate the current knowledge on the impact of diet on anti-TNF response in inflammatory bowel diseases (IBD), to identify dietary factors that warrant further investigations in relation to anti-TNF treatment response, and, finally, to discuss potential strategies for such investigations. PubMed was searched using specified search terms. One small prospective study on diet and anti-TNF treatment in 56 patients with CD found similar remission rates after 56 weeks among 32 patients with good compliance that received concomitant enteral nutrition and 24 with poor compliance that had no dietary restrictions (78% versus 67%, p = 0...

Inflammatory bowel disease (IBD) includes a set of pathologies that result from a deregulated immune response that may affect any portion of the gastrointestinal tract. The most prevalent and defined forms of IBD are Crohn's disease and ulcerative colitis. Although the etiology of IBD is not well defined, it has been suggested that environmental and genetic factors contribute to disease development and that the interaction between these two factors can trigger the pathology. Diet, medication use, vitamin D status, smoking, and bacterial infections have been proposed to influence or contribute to the onset or development of the disease in susceptible individuals...

Diet has been speculated to be a factor in the pathogenesis of inflammatory bowel disease and may be an important factor in managing disease symptoms. Patients manipulate their diet in attempt to control symptoms, often leading to the adoption of inappropriately restrictive diets, which places them at risk for nutritional complications. Health professionals struggle to provide evidence-based nutrition guidance to patients due to an overall lack of uniformity or clarity amongst research studies. Well-designed diet studies are urgently needed to create an enhanced understanding of the role diet plays in the management of inflammatory bowel disease...

Irritable bowel syndrome (IBS)-like symptoms are not uncommon in patients with quiescent inflammatory bowel disease (IBD). While gluten-free diet is applied by patients, there are no reported interventional studies. The low-FODMAP diet, on the other hand, has efficacy similar to that seen in patients with IBS in three unblinded or observational studies of IBD cohorts who had well-controlled inflammatory disease and in one small randomized cross-over study. FODMAP intake by patients with IBD is not elevated, and, in one study, fructan intakes were lower in patients with Crohn's disease than in controls...

Health-care systems around the world are facing increasing costs. Non-adherent, chronically ill patients are one such expense incurred by health-care providers. Web-based home-monitoring of patients-or eHealth-has been shown to increase adherence to medical therapy, facilitate contact between patients and health-care professionals, and reduce time to remission for patients with inflammatory bowel disease (IBD). Web-based treatment is a supportive tool for the health-care provider in an out-patient clinic. eHealth web-programs, such as the Constant Care application, visualize disease activity in a traffic light system and empower patients to screen for disease activity, enabling them to respond appropriately to their symptoms...

Prebiotics are non-digestible selectively fermented dietary fibers that specifically promote the growth of one or more bacterial genera in the gastrointestinal tract and thus provide health benefit to the host. The two most investigated prebiotics being the inulin-type fructans and galacto-oligosaccharides. Prebiotic specificity is mediated through species-specific gene clusters within saccharolytic bacteria controlled by signaling sensors for various substrates. Prebiotic health benefits are attributed to immune regulation and bacterial metabolite production...

There is growing recognition that composition and metabolic activity of the gut microbiota can be modulated by the dietary proteins which in turn impact health. The amino acid composition and digestibility of proteins, which are influenced by its source and amount of intake, play a pivotal role in determining the microbiota. Reciprocally, it appears that the gut microbiota is also able to affect protein metabolism which give rise to the view that function between the microbiota and protein can proceed in both directions...

Ambient particulate matter (PM) exposure is associated with atherosclerosis and inflammatory bowel disease. Ultrafine particles (UFP, dp < 0.1-0.2 μm) are redox active components of PM. We hypothesized that orally ingested UFP promoted atherogenic lipid metabolites in both the intestine and plasma via altered gut microbiota composition. Low density lipoprotein receptor-null (Ldlr(-/-)) mice on a high-fat diet were orally administered with vehicle control or UFP (40 μg/mouse/day) for 3 days a week...

Inflammation plays an important role in maintaining the body's homeostasis. It repairs the damaged tissues of the body resulting from injury or infection. In addition, a diverse array of diseases like hepatitis, arthritis and colitis has been reported and described to be associated with inflammatory processes. Some autoimmune diseases like inflammatory bowel disease (IBD) emerge by the influence of numerous genes in complex environmental situations belongs to inflammation. The currently available processes for curing inflammation and related disorders facilitate the use of non steroidal anti-inflammatory drugs (NSAIDs)...

BACKGROUND: Polyphenols represent a great variety of compounds occurring in fruits, vegetables and plant-derived products. Dietary polyphenols have been found displaying several biological properties, such as anti-inflammatory, antioxidant and anti-aging activities, cardiovascular and neuro-protection, and reduction of the risk of intestinal diseases. The bio-efficacy of polyphenols is tightly linked to their bioavailability, to structural complexity and composition of food matrix in which they are present...

The etiology of inflammatory bowel disease (IBD) is unknown, but it is thought to arise from an aberrant immune response to a change in colonic environment in a genetically susceptible individual. The intestinal microbiota are located at the complex interface of the epithelial barrier and are sensitive to changes in environmental factors, such as diets, drugs or smoking and signals derived from the intestinal immune system and the gut-brain axis. In patients with IBD, an imbalance in the structural and/or functional configuration of the intestinal microbiota leading to the disruption of the host-microorganism homeostasis (dysbiosis) has been reproducibly reported...
