Migraine Trigger: Personal Food Allergens
Migraine sufferers test positive for more food allergens than healthy individuals (article link).
However, a migraine sufferer can have personal food allergens that are unpredictable. For example, tomatoes are a personal food allergen and migraine trigger for a very small number of migraine sufferers.
Personal Food Allergens are Hard to Find
IgE and IgG food testing is helpful to find and eliminate personal allergens, but they are not 100 percent accurate.
Personal food allergens are also hard to find on your own because they take an average of two to three days to trigger a migraine and they may trigger migraines in combination.
For example, when combined, bananas and oranges may be a migraine trigger for some individuals even though they are not migraine triggers individually and they do not test positive as food allergens.
Personal food allergens could include bananas, beans, citrus, starch, shellfish, starch, yeast, mustard, nightshades (tomatoes, hot peppers, bell peppers, eggplant), mushrooms, spices, peas, and just about anything.
“Virtually any food can be a personal food allergen…”
Some of the more common personal food allergens can be eliminated during a very strict and medically supervised elimination diet.
However, there are still limitations because virtually any food can be a personal food allergen and allergy testing is not accurate.
It’s also possible that reducing the top headache triggers will improve the headache threshold and make personal food allergens irrelevant.
What to Do?
For these reasons, the most common approach is to reduce or eliminate the top migraine triggers and monitor all other foods in a food diary.
Look for foods or food combinations that have been consumed within three days of any headache occurring.
Eliminate any foods suspected of being a trigger.
