I've got... too many food issues, haha. I'm a finicky eater, I guess, but only some of it is me being 'picky'.
My allergies, some of which are super weird, and most of which I actually really loved before I became allergic:
Banana, honey (I don't know ANYONE else allergic to honey), curry (don't know what in the curry it is, since it's a spice blend), peanuts (formerly my fave, really recent allergen), shellfish, anything fermented tends to make me really sick, even if it's not technically an 'allergy'...
Polenta/grits, couscous... Tomato I like the taste of but hate to bite into, so I enjoy salsas and sauces and such but avoid the chunks. Some things have to be prepared a certain way-- or can't be prepared a certain way-- for texture to not set me off.
Veal, lamb... I just don't want to eat anything that's a baby! I also won't eat rabbit (used to have a house rabbit, and just generally love them), or octopus (they are so intelligent, I can't eat something so obviously sentient!)...
Just the grossest:
Mushrooms, most squashes, zucchini, rhubarb, canned green beans... It's a combo of texture issues and flavors here.
Cream sauces are just usually too rich for me, and I don't enjoy them enough to put myself through the discomfort.
Spicy foods, acidity, and fried foods all set off my acid reflux, but that doesn't mean I won't eat them-- I just have to make choices. If I'm going to eat something fried today, I need to avoid a bunch of spice and acid in the rest of my meals, and eat blander foods the next day, if I want orange juice then I can't have a lot of oil or spice that day...
