Cuisines low in glutamate/umami?

I'm cutting back on foods high in msg in all forms, as well as free glutamate that occurs naturally (like in long-simmered tomato sauce, aged Parmesan cheese, soy sauce, etc. -- the taste sometimes described as "umami"). In other words, cutting back on lots of amazingly delicious foods! Turns out they trigger migraines for me, so it seemed like a good call.

My question: I'd love to identify cultures/cuisines that are naturally *low* in high-glutamate ingredients. It would be great to eat/cook delicious, authentic food that is headache-free. Any ideas or recommendations would be great!
