Patients with fibromyalgia demonstrate significantly lower adherence to the Mediterranean diet compared to those with rheumatoid or psoriatic arthritis. A cross-sectional study of 422 participants reveals that dietary patterns vary meaningfully across rheumatologic diseases, with fibromyalgia patients showing the lowest compliance scores.
Higher adherence to this dietary pattern correlates directly with reduced disease burden. Data indicates that fibromyalgia patients maintaining closer adherence report lower impact questionnaire scores and reduced polysymptomatic distress. Sensitivity analyses confirm these associations, suggesting nutrition plays a distinct role in managing fibromyalgia severity that is not observed in other arthritic conditions.
Lifestyle factors further differentiate this demographic. Nearly half of fibromyalgia participants reported food intolerances, leading to frequent restrictive eating. Approximately 35% follow lactose-free diets while 15% avoid gluten. These self-directed restrictions may inadvertently reduce overall Mediterranean diet adherence.
Researchers emphasize that while causality remains unproven, nutritional counseling warrants integration into multidisciplinary care. Future longitudinal studies are necessary to determine if targeted dietary interventions can actively reduce fibromyalgia burden or if symptom management simply enables healthier eating habits.
