Core Tip

Core Tip: Fibromyalgia (FM) syndrome is mainly characterized by widespread pain but in many cases, gastrointestinal distress is also reported, suggesting the potential pathogenic role of the intestinal microbiota. Since gut microbiota is deeply influenced by diet, significant symptom improvement has been reported in FM patients following various nutritional interventions such as vegetarian diet, low-fermentable oligosaccharides, disaccharides, monosaccharides, and polyols based diets, gluten-free diet, and especially an ancient grain based diet. We reported that a replacement diet based on ancient Khorasan wheat, compared to a control wheat diet, resulted in beneficial gut microbiota compositional and functional modifications that positively correlated with an improvement of FM symptomatology.
