I know I never appreciated the flavors of vegetables until I went on a strict allergy diet - meaning no salad dressings at restaurants, because I couldn't have vinegar at all, and couldn't be sure that oil didn't contain corn oil.

Now that I'm not so strict, a few drops on a fork is plenty to flavor a salad. It's not that I don't like the flavors of salad dressings, but I have no desire to smother the flavor of the vegetables, either.

Ice cream's another thing that I don't desire one bit. If I taste a half a spoonful of someone else's, in a vacuum I could say I enjoy the way it tastes. But I can't separate it from how awful it's going to make me feel. No desire at all.
