Food Implications in Central Sensitization Syndromes.
Aguilar-Aguilar, Elena, Marcos-Pasero, Helena, Ikonomopoulou, Maria P et al. · Journal of clinical medicine · 2020 · DOI
Quick Summary
This review examined what is known about how food affects three related conditions—fibromyalgia, ME/CFS, and multiple chemical sensitivities—that all involve heightened nervous system sensitivity. The authors found that changing diet can help improve quality of life for many patients, but the best approach is personalized and done with help from a dietitian and doctor. They warn against following strict diets without professional guidance.
Why It Matters
ME/CFS patients frequently report food sensitivities and seek dietary guidance but face contradictory advice. This review consolidates fragmented evidence to help clarify what dietary approaches have support and emphasizes the need for personalized, supervised interventions rather than one-size-fits-all recommendations.
Observed Findings
- Dietary modifications may improve quality of life in CSS patients at relatively low cost
- Micronutrient deficiencies appear present in some CSS populations
- Food additives may trigger symptoms in sensitive individuals
- Multisyndromic patients (overlapping FM, CFS, MCS) require different nutritional approaches
- Personalized interventions considering disease severity, comorbidities, and individual food tolerances show promise
Inferred Conclusions
- Personalized dietary management tailored to individual symptom severity, nutritional status, and tolerances is more appropriate than standardized dietary protocols for CSS patients
- Dietary interventions warrant consideration as a low-cost, quality-of-life-improving component of CSS management
- Supervision by both clinicians and registered dietitians is essential to prevent harm from unsupervised dietary restrictions
Remaining Questions
- What specific micronutrient deficiencies are most common and clinically significant in ME/CFS populations?
- Which food components or additives trigger symptoms in which patient subgroups, and what are the underlying mechanisms?
What This Study Does Not Prove
This review does not establish causation between specific foods and CSS symptoms, nor does it identify universal dietary interventions effective for all patients. The contradictory evidence noted suggests that current data cannot definitively prove which nutrients or elimination strategies are necessary for any given patient.

About the PEM badge: “PEM required” means post-exertional malaise was an explicit required diagnostic criterion for participant inclusion in this study — not that PEM was studied, observed, or discussed. Studies using criteria that do not require PEM (e.g. Fukuda, Oxford) are tagged “PEM not required”. How the atlas works →
