#Dietary fibre counters the oncogenic potential of colibactin-producing Escherichia coli in colorectal #cancer

Diet, microbiome, inflammation and host genetics have been linked to colorectal cancer development; however, it is not clear whether and how these factors interact to promote carcinogenesis. Here we used Il10−/− mice colonized with bacteria previously associated with colorectal cancer: enterotoxigenic Bacteroides fragilis, Helicobacter hepaticus or colibactin-producing (polyketide synthase-positive (pks+)) Escherichia coli and fed either… Continue reading #Dietary fibre counters the oncogenic potential of colibactin-producing Escherichia coli in colorectal #cancer

Impact of Plant-Based Dietary #Fibers on Metabolic Homeostasis in High-#Fat Diet Mice via Alterations in the Gut #Microbiota and Metabolites

BackgroundThe gut microbiota contributes to metabolic disease, and diet shapes the gut microbiota, emphasizing the need to better understand how diet impacts metabolic disease via gut microbiota alterations. Fiber intake is linked with improvements in metabolic homeostasis in rodents and humans, which is associated with changes in the gut microbiota. However, dietary fiber is extremely… Continue reading Impact of Plant-Based Dietary #Fibers on Metabolic Homeostasis in High-#Fat Diet Mice via Alterations in the Gut #Microbiota and Metabolites

#Diet shapes the metabolite profile in the intact human ileum, which affects PYY release

The human ileum contains a high density of enteroendocrine L-cells, which release the appetite-suppressing hormones glucagon-like peptide-1 (GLP-1) and peptide tyrosine tyrosine (PYY) in response to food intake. Recent evidence highlighted the potential role of food structures in PYY release, but the link between food structures, ileal metabolites, and appetite hormone release remains unclear owing… Continue reading #Diet shapes the metabolite profile in the intact human ileum, which affects PYY release

Opposing diet, #microbiome, and metabolite mechanisms regulate inflammatory #bowel disease in a genetically susceptible host

Highlights•Dietary fiber-deprived gut microbiota elicits lethal colitis in Il10−/− mice•Mucolytic gut bacteria weaken mucus and drive inflammatory immune responses•Alterations in bacterial IgA coating and increased NK cells precede inflammation•Exclusive enteral nutrition promotes bacterial isobutyrate, reducing inflammationSummaryInflammatory bowel diseases (IBDs) are chronic conditions characterized by periods of spontaneous intestinal inflammation and are increasing in industrialized populations. Combined with… Continue reading Opposing diet, #microbiome, and metabolite mechanisms regulate inflammatory #bowel disease in a genetically susceptible host

Association of Diet and Antimicrobial Resistance in Healthy U.S. Adults

Antimicrobial resistance (AMR) represents a significant source of morbidity and mortality worldwide, with expectations that AMR-associated consequences will continue to worsen throughout the coming decades. Since resistance to antibiotics is encoded in the microbiome, interventions aimed at altering the taxonomic composition of the gut might allow us to prophylactically engineer microbiomes that harbor fewer antibiotic… Continue reading Association of Diet and Antimicrobial Resistance in Healthy U.S. Adults

Global, distinctive, and personal changes in molecular and microbial profiles by specific fibers in humans

Dietary fibers act through the microbiome to improve cardiovascular health and prevent metabolic disorders and cancer. To understand the health benefits of dietary fiber supplementation, we investigated two popular purified fibers, arabinoxylan (AX) and long-chain inulin (LCI), and a mixture of five fibers. We present multiomic signatures of metabolomics, lipidomics, proteomics, metagenomics, a cytokine panel,… Continue reading Global, distinctive, and personal changes in molecular and microbial profiles by specific fibers in humans

#Gut-microbiota-targeted #diets modulate human immune status

Diet intervention with systems profiling reveals links in diet-microbiome-immune axis•High-fiber diet changes microbiome function and elicits personalized immune responses•Fermented-food diet increases microbiome diversity and decreases markers of inflammation SummaryDiet modulates the gut microbiome, which in turn can impact the immune system. Here, we determined how two microbiota-targeted dietary interventions, plant-based fiber and fermented foods, influence… Continue reading #Gut-microbiota-targeted #diets modulate human immune status

High-#Fiber, Whole-Food Dietary Intervention Alters the Human Gut #Microbiome but Not Fecal Short-Chain Fatty Acids

Dietary shifts can have a direct impact on the gut microbiome by preferentially selecting for microbes capable of utilizing the various dietary nutrients. The intake of dietary fiber has decreased precipitously in the last century, while consumption of processed foods has increased. Fiber, or microbiota-accessible carbohydrates (MACs), persist in the digestive tract and can be… Continue reading High-#Fiber, Whole-Food Dietary Intervention Alters the Human Gut #Microbiome but Not Fecal Short-Chain Fatty Acids
