Are there different kinds of food allergies besides anaphylaxis? (i.e. one that causes you ingest more of a food than you should)

I was once told that I had an allergy to dairy, because I have a hard time limiting my intake of it, once I have eaten it. For example, it is very difficult for me to just have one cube of cheese, or one scoop of ice cream. It takes much more willpower to limit my consumption of dairy more than any other food. Is this because of an allergy of some sort? Or maybe some other reason?
