Dietary Intervention for Migraine Relief

The goal of this clinical trial is to evaluate whether a low-glutamate diet can improve migraine symptoms in adults with migraine and to explore possible biological changes associated with dietary improvement. The study focuses on whether reducing dietary glutamate intake may influence processes involved in migraine, such as brain excitation, inflammation, and oxidative stress. The main questions this study aims to answer are: Does following a low-glutamate diet reduce the number of migraine days and the severity and duration of migraine attacks, and improve quality of life? Are improvements in migraine symptoms associated with changes in blood-based biological markers related to migraine activity? Researchers will compare participants assigned to the low-glutamate diet with participants assigned to a wait-list control group to evaluate differences in migraine outcomes and related biological measures. Participants will: Complete a baseline run-in period while tracking headaches using a daily migraine diary Either follow a low-glutamate dietary intervention or continue their usual diet as part of a wait-list control Complete standardized questionnaires related to migraine symptoms and quality of life Provide blood samples for laboratory analyses Undergo neuroimaging assessments (for a subset of participants)
