Well, something for "food video" is pretty generic and open-ended, doesn't really tell us what you are doing or what your camera needs and requirements are. Other than, at some point, food is involved in some fashion.
That being said, though, the C100 is an excellent camera. Since you mentioned you can't afford a C300, that leads me to believe that in a perfect world the C300 would be your camera of choice. If that's true, the C100 should do most if not all of the things that you'd ask of the C300. Can you afford the C200? I don't think there's a huge price difference, and the C200 will have several advantages over the C100.
