If your migraines seem random, but often follow certain meals — pizza, chocolate, bread, wine, or heavy restaurant food — delayed IgG food sensitivities may be part of the picture. These reactions can quietly increase inflammation and change how your brain and blood vessels respond to everyday foods.
Not all migraines are food-related. Hormones, stress, sleep, environment and medical conditions all play roles. But for some people, certain foods repeatedly show up before a migraine attack — even when hours or a full day separates the food and the headache.
These delayed immune reactions can increase low-grade inflammation, affect the gut–brain connection and change vessel tone and neurotransmitters involved in headache pathways. Our article Does Food Sensitivity Cause Headaches & Migraines? goes deeper into the mechanisms.
To understand how this is different from classic food allergy or intolerance, see:
Everyone’s triggers are different, but certain patterns show up repeatedly in people with food-related headaches and migraines. These often overlap with other symptoms like bloating, fatigue, mood changes or skin issues.
Instead of guessing which foods are involved, the Pinnertest Food Sensitivity Test measures IgG reactions to more than 200 foods. Your report shows which foods provoke the highest reactions so you can focus your elimination efforts where they matter most.
To see how Pinnertest works and how it differs from allergy testing, explore:
If you notice patterns between certain foods and your migraines, you can start by tracking both for a few weeks — noting what you ate, when symptoms appear and which other signs (bloating, fatigue, mood changes) show up with them.

These guides can help you plan that process:
No. Pinnertest does not diagnose migraines or any medical condition. It measures IgG food sensitivities, which may be one contributing factor in some people. Your migraine diagnosis and treatment plan should always be managed by your healthcare provider or neurologist.
Many people have multiple triggers: hormones, stress, lack of sleep, environment and sometimes food. Even if food is not the primary cause, reducing specific trigger foods may still help some people lower their attack frequency or intensity. Always coordinate any diet changes with your provider.
Some people notice changes within a few weeks of removing high-reactive foods, while others may need a longer trial. Our article How Long to Feel Better After Eliminating Foods explains typical timelines and why tracking is important.
Not necessarily. Many elimination plans use a temporary removal period followed by supervised reintroduction to see how your body responds. The goal is to better understand your personal thresholds, not to create an unnecessarily restrictive diet. This should always be done with guidance from your healthcare provider.
