I don't think I have particularly weird food hang-ups. When I was younger I was the type to eat all of one item on my plate before moving to any other item, but I've broken myself of that habit.
Probably my biggest "weird" thing is that I find it completely acceptable to not eat anything until dinner. I've had a lot of people tell me that they get headaches, or feel ill, by early afternoon if they haven't eaten anything. My wife says that not eating anything until dinner is an unhealthy habit. But I've never had a problem. I can go all day, especially when I'm busy at work, and not even feel remotely "hungry" until the late afternoon.
Other than that, I'm a very adventurous eater, and not particularly picky. I generally avoid sweets, and there are a few things that I find offputting [coconut, most refried beans, etc], but in general I'm willing to try just about anything. I honestly love traveling in Asia for just that reason. I can--and do--get to try a lot of things that I wouldn't ever normally encounter in the US.
