If someone can reasonably consider it food, fair to say that is food for the sake of this.
Like I said, I haven't met the food I don't like yet. It is impossible to know how I feel about the foods I haven't yet met. There is an infinite selection of food out there. Perhaps something will cross my plate someday that turns up my nose. I always try new foods when I have the opportunity, but that day hasn't yet come.
I can buy "I'll eat anything." If what you mean is "I like everything that someone somewhere will consider to be food," well, color me skeptical.
