Safe foods

I often wonder if there is such a thing as safe food for any migraien sufferer.

I try to eat healthy and prepare all my meals myself from the basic ingredients, I avoid fatty fried food, never buy ready meals or processed sauces etc, I also eat lots of vegetables and fruit (when in season) so I consider my diet to be reasonably healthy.
I know that in this way I save myself from few more M.

I am sure that many foods trigger M from the previous experience, so I obviously I try to avoid them.
But in the end, I am never sure what is safe, and what is not, and if there is such thing as completely safe food.
Any ideas on the subject? Can we try to create a list of what we think is a safe food?
