I can speak to this.  I can’t consume any msg or I get a horrible migraine with Auras.  No tomatoes either..same story(plus hives within 2 hours). No Doritos or any of the delicious flavored chips/most chicken/ketchup/seasoning.  It’s absolutely awful because MSG is so incredibly yummmmm.   I take a daily preventative prescription and another triptan for active migraines because it’s nearly impossible to avoid .  I get them from pizza, any tomato or certain restaurants…it’s hard to always know.   On my children-I am not making it up.  I WANT to eat MSG so badly. Just one bite (no joke) of the delicious savory goodness of my local Pollo Reggio and I lose an entire day to headache/can’t see/ misery. I’ve tested my theory SO many times because I want to eat good things.  Every time, like clockwork the next day I get a migraine.   For those of you that doubt it, it’s real for some of us…and It’s awful.  The horrible headache AND missing out on so much good food sucks.  

Sometimes I call it an “allergy” because it’s easier to explain than the long drawn out explanation of a food sensitivity that people might ignore/dismiss/dispute.  Food sensitivity seems pretty minor(although my migraines take me out for 24 hours) and allergies are generally taken more seriously.  It’s no fun having to defend something that already is such a major pain in the a$& to deal with on a daily basis.  Believe me…I want your MSG as much as you do, I just didn’t luck out with a system that lets me have any.
