Chocolate is often blamed for triggering migraines. I know of one Italian study where migraine sufferers had to eat chocolate on certain days, and the migraines experienced the following day were monitored. According to the study, chocolate does not cause migraines.
Why do many people feel chocolate triggers their migraine?
This is related to the premonitory symptoms of migraine, which can occur up to two days before the pain phase. Increased appetite, especially a craving for sweets, can be among the first symptoms of migraine. Afterwards, it might feel as if eating chocolate caused the migraine, when in reality, the migraine caused the craving for chocolate.
What does chocolate contain?
Chocolate contains small amounts of caffeine and theobromine, which has similar but milder effects to caffeine. For some, sleep quality may deteriorate after eating chocolate, and sleep disturbances can predispose to migraines.
Should chocolate be avoided?
Chocolate, especially dark chocolate (over 70% cocoa), has several proven positive health effects when consumed in moderation. The most significant benefits are related to cardiovascular health, antioxidant effects, and mood improvement.
Flavonoids in dark chocolate can lower blood pressure, improve blood vessel function, and reduce the oxidation of LDL cholesterol, which protects the heart and blood vessels.
Additionally, chocolate contains tryptophan and phenylethylamine, which promote serotonin production and can improve mood.
Summary
Eating chocolate is good for your health, as long as it doesn't trigger migraine attacks based on your observations. However, milk chocolate is not the best option – dark chocolate is a better choice.
