Confirmation of Diet as a Treatment for Gulf War Illness

This study tests whether a specific dietary intervention can reduce symptoms of Gulf War Illness (GWI) — a poorly understood chronic condition affecting many veterans of the 1990-1991 Gulf War. Researchers believe that dietary changes affecting brain chemistry may help reduce fatigue, pain, and cognitive symptoms. You may be eligible if... - You are a Gulf War veteran aged 50 to 75 - You meet both the CDC and Kansas definitions of Gulf War Illness - Your medications and supplements have been stable for at least 1 month - You are willing to maintain stable medications throughout the study You may NOT be eligible if... - You have had a substance use disorder in the past year - You are unwilling to stop using alcohol, tobacco, vaping, or marijuana - You are unwilling to change your diet as part of the study - You have a diagnosed seizure disorder or severe asthma requiring hospitalization - You currently take medications affecting glutamate or GABA brain signaling (unless you can safely wean off with your doctor) Talk to your doctor about whether your Gulf War Illness meets the required criteria, your current medications, and whether dietary changes are medically safe for you.
