Faecal and urine metabolites, but not gut microbiota, may predict response to low FODMAP diet in irritable bowel syndrome Fecal Microbial Composition and Predicted Functional Profile in Irritable Bowel Syndrome Differ between Subtypes and Geographical Locations Long-term personalized low FODMAP diet improves symptoms and maintains luminal Bifidobacteria abundance in irritable bowel syndrome Role of the microbiome in regulating bone metabolism and susceptibility to osteoporosis The Impact of Almonds and Almond Processing On Gastrointestinal Physiology, Luminal Microbiology and Gastrointestinal Symptoms: a Randomized Controlled Trial and Mastication Study Long-term personalised low FODMAP diet improves symptoms and maintains luminal Bifidobacteria abundance in irritable bowel syndrome Psyllium reduces inulin-induced colonic gas production in IBS: MRI and in vitro fermentation studies Contrasting effects of viscous and particulate fibers on colonic fermentation in vitro and in vivo, and their impact on intestinal water studied by MRI in a randomized trial Dietary fibre in gastrointestinal health and disease Emulsifiers impact colonic length in mice and emulsifier restriction is feasible in people with Crohn’s disease Fibre from nopal cactus (Opuntia ficus-indica) improves symptoms in irritable bowel syndrome in the short term: A pilot randomised-controlled trial Food additive emulsifier restriction is feasible in people with Crohn's disease Food additive emulsifiers: a review of their role in foods; legislation and classifications; presence in food supply; dietary exposure; and safety assessment Food additive emulsifiers and their impact on gut microbiome, permeability and inflammation: mechanistic insights in inflammatory bowel disease Low FODMAP diet & prebiotic β-galactooligosaccharides improve irritable bowel syndrome and response to low FODMAP is predicted by urine and faecal metabolites: A randomised controlled trial Nopal fiber (Opuntia ficus-indica) improves symptoms in irritable bowel syndrome in the short term: a randomized-controlled trial Prebiotic β-galacto-oligosaccharide impact on clinical, inflammatory and microbiota outcomes in active ulcerative colitis: An open-label study β-Galactooligosaccharide in Conjunction With Low FODMAP Diet Improves Irritable Bowel Syndrome Symptoms but Reduces Fecal Bifidobacteria β-Galactooligosaccharide in Conjunction With Low FODMAP Diet Improves Irritable Bowel Syndrome Symptoms but Reduces Fecal Bifidobacteria β-galacto-oligosaccharide in conjunction with low FODMAP diet improves irritable bowel syndrome symptoms but reduces fecal bifidobacteria Fermented Foods: Definitions and Characteristics, Impact on the Gut Microbiota and Effects on Gastrointestinal Health and Disease Nutrition: an old science in a new microbial light Prebiotics in irritable bowel syndrome and other functional bowel disorders in adults: a systematic review and meta-analysis of randomized controlled trials Dietary fiber intervention on gut microbiota composition in healthy adults: a systematic review and meta-analysis Beyond Sodium, Phosphate and Potassium: Potential Dietary Interventions in Kidney Disease Irritable bowel syndrome and diet: Where are we in 2018?
