The research, published in the Journal of Headache and Pain, revealed that 35 out of the 40 subjects tested reported a significant improvement in the level of pain and frequency of migraines when triggers such as meat and diary produces were eliminated.
The results were attributed to different mechanisms in particular as migraine involves involvement of neurogenic inflammation and neurogenic vasodilation. Many plant foods contain a high level of antioxidant and anti-inflammatory compounds. Previous studies have revealed that meat products have inflammatory properties and some cheese and meat products contain tyramine which has also been linked to migraine.
The researchers also attribute the fact that vegan diets often cause lower blood pressure and hormonal changes, which again may impact on migraine symptoms.
Most of the study participants chose to continue with a vegan based diet recognizing the obvious health benefits attributed to the life style.
