Effect of food additives on key bacterial taxa and the mucosa-associated microbiota in Crohn’s disease. The ENIGMA study
In addition to their direct effects on bacterial growth, polysorbate 80 and/or carboxymethylcellulose can drive profound changes in the CD mucosa-associated microbiota via niche expansion of Proteus and/or Veillonellaceae – both implicated in early Crohn’s disease recurrence. These studies on the interaction of food additives with the enteric microbiota provide a basis for dietary management in Crohn’s disease.

To Fiber or Not to Fiber: The Swinging Pendulum of Fiber Supplementation in Patients with Inflammatory Bowel Disease
This review describes dietary fibers and their mechanism of action within the microbiome, details novel fiber sources, including resistant starches and polyphenols, and concludes with potential future directions in fiber research, including the move toward precision nutrition.

P380 Changes in faecal microbiome and metabolome are more pronounced in Crohn’s disease patients who adhered to the CD-TREAT diet and responded by calprotectin.
Treatment with the CD-TREAT solid food diet improves disease activity indices, faecal calprotectin (FCAL) levels and quality of life in adults and children with active Crohn’s disease (CD); particularly in patients who adhere to the diet. Here we describe changes in faecal microbiome parameters during therapy with CD-TREAT and explore these changes against adherence.

Unfermented β-fructan Fibers Fuel Inflammation in Select Inflammatory Bowel Disease Patients
Inflammatory bowel diseases are overall beneficially impacted by dietary fibers that are fermented by colonic microbes. Unfermented dietary β-fructan fibers induced proinflammatory cytokines in a subset of inflammatory bowel disease patient samples, via activation of the NLRP3 and TLR2 pathways; inflammation was reduced via fermentation by microbes.

The Effects of Commonly Consumed Dietary Fibres on the Gut Microbiome and Its Fibre Fermentative Capacity in Adults with Inflammatory Bowel Disease in Remission
Despite extensive microbial dysbiosis, patients with IBD have a similar capacity to ferment fibre and release SCFA as HC. Fibre supplementation alone may be unlikely to restore to a healthy status the compositional shifts characteristic of the IBD microbiome.

Dietary manipulation of the gut microbiome in inflammatory bowel disease patients: Pilot study
In conclusion, we demonstrate that the IBD-AID can favor bacteria commonly depleted in IBD patients which are key for maintaining immune tolerance and homeostasis in the gut via SCFA production. We demonstrated that foods encouraged/discouraged by the IBD-AID are linked to modulation of the immune tone.

Gut-Microbiota-Targeted Diets Modulate Human Immune Status
Two microbiota targeted interventions, plant based fiber and fermented foods, influence the human microbiome and immune system, whereby coupling them may provide longitudinal benefit.

Long-term Dietary Patterns are Associated with Pro-Inflammatory and Anti-Inflammatory Features of the Gut Microbiome
Authors identify dietary patterns that consistently correlate with groups of bacteria with shared functional roles in health and disease. Specific foods and nutrients were associated with species known to infer mucosal protection and anti-inflammatory effects, proposing a microbial mechanism for anti-inflammatory dietary effects
