Regarding bananas… Yes, they’re a definite trigger because they contain tyramine.
A few months ago, some of us put together some Wiki pages and included information and links that we had found in our research. I posted several things in the Diet Wiki, which you can find here:

Scroll down to my post and then go to the “Yes List” and “No List” images. Then just below that there is a link for a “Tyramine-safe food list.”
Tyramines are compounds produced by the breakdown of an amino acid called tyrosine. Basically in some foods, the tyramine levels build up as the food ages. So a ripe banana contains more tyramine than a greener banana. Aged foods containe more tyramines than fresh foods.
For some people, tyramines are a migraine trigger. That’s why you’ll frequently see things like aged cheese and red wine on lists as possible triggers.
I have a friend who says that bananas are a major trigger for her.
