I stopped eating cheese at around 4 or 5 years of age. I just stopped liking it one day and started hating it instead. When I turned 25 I began eating pizza as an experiment, and had no problems with it, but still many years later I do avoid cheese and other dairy products in most situations. I suspect it might have something to do with lactose intolerance, but I have never attempted to verify this.
