Chocolate and migraines
Migraines are debilitating headaches caused by spasms of the arteries leading to the brain. The underlying mechanisms remain unclear, but a number of triggers seem to be needed to start the migraine process. Certain foods, including chocolate, are commonly cited as triggers. For most sufferers, however, chocolate can’t start the migraine chain reaction by itself.
Numerous international trials have found that other factors, such as stress (as a result of tiredness, excitement or anger) and hormones need to be present at the same time.
More research is needed to clarify the link between chocolate and migraines.
