Some food allergens are more likely to be migraine triggers, but personal food allergens can be unpredictable. Document everything you eat in a food diary and eliminate foods or combinations of foods that are repeatedly noted as having been consumed within three days of a migraine occurring
Lectins are found in most healthy foods; however, foods with high levels of lectins have been found to stress the digestive track. Foods with high concentrations of lectins should not be consumed in excess.
Sulfites are a suspected migraine trigger, but research is limited. Sulfites are found in natural foods, but they contain less than 10 parts per million (ppm). Foods with over 10 ppm of sulfites must be labeled and may actually contain over 200 times the amount of sulfites found in nature.
