A 4-week low FODMAP diet can impact the gut microbiota to some degree in gluten-free diet-treated celiac disease patients having persistent gastrointestinal symptoms.
In a recent groundbreaking study, researchers have found that a diet low in fermentable oligo-, di-, monosaccharides and polyols (FODMAP) can be a game-changer for individuals with celiac disease who still experience gastrointestinal symptoms in spite of adhering to a gluten-free diet (GFD).
The study, a randomized controlled trial involving GFD-treated celiac disease adults with persistent gastrointestinal issues, investigated the impact of a combined low FODMAP diet (LFD) and GFD on gut health.
Participants were divided into two groups: one consumed the LFD and GFD combination (n=39), while the other continued with the GFD alone (n=36). Remarkably, the LFD group showed significant changes in their overall faecal microbiota profile compared to the control group. Using 16S rRNA gene sequencing, researchers found a distinct shift in the gut microbiota of those following the LFD. Specifically, there were lower levels of genus Anaerostipes and higher levels of class Erysipelotrichia in the LFD group.
Despite concerns about the LFD's potential impact on gut health, the study revealed no adverse effects on faecal bacterial α-diversity or faecal neutrophil gelatinase-associated lipocalin, a biomarker of gut integrity and inflammation. This indicates that the LFD had a modest effect on the gut microbiota while maintaining gut health. Moreover, participants with high faecal propionic and valeric acid concentrations at baseline experienced lower levels after following the LFD, suggesting promising benefits for those with elevated levels of these compounds.
Overall, the results of this study provide encouraging evidence for the effectiveness of the LFD strategy in alleviating functional gastrointestinal symptoms in celiac disease patients. This breakthrough could bring much-needed relief to individuals suffering from this chronic condition and potentially improve their quality of life. Further research is likely to build upon these findings, as scientists continue to explore innovative dietary approaches for managing and treating celiac disease and related gastrointestinal disorders.
