Yup, those are the ones. I used to get optical migraines fairly frequently. I stopped wheat for unrelated reasons about 12 years ago and haven't had a migraine since. Makes driving a lot safer.

interesting. i have also noticed that i don't get this problem anymore, but what was mainly causing it for me was energy drinks, combined with, probably, a lot of barley malt, so, yeah, gluten there.
idk hwat it is, inositol, glucuronolactone, one of those. has some interaction with the immune system, and i think that what's happening is inflammation in the visual cortex.
Hmm. Who knows what other havoc it was causing. Visual is probably the most obvious. But I wouldn't be shocked to learn that my general cognitive ability dropped across the board.
