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.
Most cheese, really. I mean, I can eat it, but it rarely adds anything good to a meal for me. It wasn’t until I spent a good chunk of time in Erope ad came that I realized how much cheese we put on everything and how it just makes everything taste like, well, cheese.
So, I no longer add cheese as a topping to most things.
