One Mayo Clinic researcher and one of the
institute’s neurologists said
in a news
site, that some migraine sufferers might be experiencing
symptoms from a mild, undiagnosed food allergy. He noted that
more research needed to be done in the area of the link between
migraines and food allergies. Pointing to a recent study
published in the journal Cephalalgia, he explains that a
migraine headache may be a immunological response.
The study involved testing migraine sufferers for IgG
antibodies against 266 different foods. If the antibodies were
present, it meant the person had allergy to that particular
food. Study participants were first put on a diet rich in foods
that they were allergic to then placed on a diet that
eliminated those foods. The researches compared frequency and
severity of headaches between the two diets and found that the
number of attacks and the number of days with a headache was
lowered on the elimination diet.
The researcher suggested that people suffering from unexplained
migraines may want to get tested for food allergies that either
were previously undiagnosed or that aren’t so severe that
they cause other symptoms or forms of illness.
