"This mutation means migraine sufferers are likely to have higher levels of a particular amino acid or protein called homocysteine in the blood. But a diet rich in folate can reduce levels of homocysteine. For many people folate-rich foods such as green vegetables or folate supplements could not only help ward off migraines but may also help prevent strokes."

Dr Lea says it is too early to say whether folate rich diets are the cure-all for people who suffer from migraine. But the appeal of this therapy is that it is not only simple and cheap, but may also help prevent migraine attacks in people for whom traditional drugs are not effective.

The results of the study have been published in a leading international medical journal. The team is now hoping to organise clinical trials to assess how effective folate can be in reducing migraine symptoms.
