Summary

This study looks at whether eating less glutamate—a natural compound found in many foods—can reduce the number and severity of migraine attacks in adults. Forty participants will either follow a low-glutamate diet or continue their usual eating habits while tracking their headaches. Researchers will also check blood samples for biological changes linked to migraine improvement.
