Chocolate: Trigger or Craving?

There is a belief that chocolate is a migraine trigger for many people. Some people eat chocolate before a migraine and then believe the chocolate caused it. But what if chocolate is a craving indicating a migraine has already started?


According to the American Migraine Foundation, chocolate is the second most common trigger; 22% of people with migraine reported chocolate as a trigger. According to Histamine Intolerance Awareness in the UK, chocolate and cocoa-based products are high in histamine. Histamine affects the central nervous system by dilating (widening) blood vessels in the brain, thought to be a cause of migraine.


On the other hand, craving chocolate can be an indication a migraine is on its way. Cravings can be part of a migraine's prodrome (initial) phase, so it is easy to see why some people misinterpret this craving as a trigger.


If you think chocolate is a trigger for your migraines, you could try an experiment. When you feel good, and your migraine threshold is high, try a bit of chocolate. If you get a migraine, chocolate may indeed be a trigger for you. However, if you love chocolate, you might want to try at least a couple of times to be absolutely certain!
