There's definitely something going on between my digestive system and corn, I know, but I'm not sure of the extent. Seemed to be corn on the cob makes me violently ill but I'm just fine with corn OFF the cob, and it had been yellow corn chips/taco shells made me sick but white corn ones were fine, except today I've spent most of the afternoon in misery apparently from white chips so I DON'T KNOW. I don't think it's one of those things where even, like, corn syrup is problematic, but maybe it IS (just less violently than corn on the cob), and that's why avoiding sugar has improved my mood/health-- because it's not sugar it's corn syrup. How would I go about getting something like that diagnosed?
