I’ve got a pretty severe sensitivity to – of all things – sugar. (I know, “sugar” isn’t very precise, but I’m pretty sure it’s either glucose, fructose, or sucrose.) I virtually never eat anything with added sugar or anything with any significant amount of natural sugar. And I’ve eaten that way for like 20 years now. I’m practically blind to half the produce department (any “sweet” fruits like apples, pears, cherries, grapes, oranges, etc) at the grocery store, let alone the candy isle.
Bologna
Breakfast cereal
I haven’t had either, in any way, shape or form, in decades.
There’s another one but this I’d like to try again - root beer with two scoops of vanilla ice cream. I’ve had the ice cream, but not the root beer.
