What this trial studies

This clinical trial aims to confirm previous findings that a specific dietary intervention can significantly improve symptoms in veterans with Gulf War Illness. Participants will be randomized into either the dietary intervention group or a wait-listed control group, with assessments conducted before and after one month of the intervention. The study will also explore changes in the nervous system and identify blood markers associated with symptom improvement. By including a larger and more diverse group of veterans, the research seeks to validate earlier results and enhance understanding of the diet's effects.

Who should consider this trial

Good fit: Ideal candidates are veterans who served in the 1990-1991 Persian Gulf War and meet the criteria for Gulf War Illness.

Not a fit: Patients with recent substance use disorders or those unwilling to change their diet may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a no-risk, low-cost treatment option for veterans suffering from Gulf War Illness.

How similar studies have performed: Previous smaller studies have shown significant improvements with similar dietary interventions, suggesting potential for success in this larger trial.
