I've got a food intolerance with mustard, seafood and certain fish like salmon, peanuts and things with huge amounts of vinegar, I still eat a lot of these things but just dose up on anti-histamines which work half the time. It's not an allergy as such as I don't suffer an anaphylactic shock, I just go red and rashy, my heart pounds, breathing gets a bit rapid I get a strange taste in my mouth and a bad headache. I think I have an intolerance to ar*eholes too, as I react in much the same way.
