A migraine headache is a form of vascular headache caused by vasodilatation (enlargement of blood vessels) that causes the release of chemicals from nerve fibers that coil around the large arteries of the brain. Enlargement of these blood vessels stretches the nerves that coil around them and causes the nerves to release chemicals. The chemicals cause inflammation, pain, and further enlargement of the artery. The increasing enlargement of the arteries magnifies the pain.
Some of the symptoms associated with migraine attacks are nausea, vomiting, and diarrhea.
According to a report published in the journal Pediatric Neurology, the list of foods, beverages, and additives thought to trigger migraine symptoms in some people includes:
• Citrus fruits
• Hot dogs
• Monosodium glutamate (www.2u2eat.com)
• Fatty foods
• Ice cream
• Caffeine withdrawal
• Alcoholic drinks, especially red wine and beer
Published surveys have found that the most commonly reported food triggers are cheese, chocolate, alcohol, bananas, and citrus fruit.
