Celiac disease is an autoimmune condition triggered by gluten ingestion, leading to chronic inflammation of the small intestine. This damage alters the intestinal mucosa and impairs nutrient absorption. The only treatment is a strict gluten-free diet, which generally controls symptoms but does not fully restore intestinal function.
In this context, increased fiber intake is often recommended to support digestion and gut health. However, the effectiveness of this strategy may be limited by a previously underestimated factor: the composition of the gut microbiome.
