It would likely be just for glutamates since they are a core excitotoxin we as a species consume the most and which can propagate cell responses that might not be good for certain people, still though there's not enough research to really nail stuff down besides glutamates being a factor in cell death when overabundant.
Depends entirely on the context of migraine. I get headaches with glutamates, never have a problem if I avoid those foods.
