CHOCOLATE IS A MIGRAINE-PROVOKING AGENT

Patients with migraine who believed that chocolate could provoke their attacks were challenged with either chocolate or a closely matching placebo. In a double-blind parallel group study, chocolate ingestion was followed by a typical migraine episode in 5 out of 12 patients, while none of the 8 patients challenged with placebo had an attack (p = 0.051). The median time to the onset of the attack was 22 h. This brief study provides some objective evidence that chocolate is able to provoke a migraine attack in certain patients who believe themselves sensitive to it.
