I come out in a rash when I eat some brands of chocolate - the more expensive sort - but do not when I eat the best known brand on the market in Britain. Does this mean I have a food allergy or is this an intolerance?
Rashes are typical of allergic responses. There may be some kind of oil or emulsifier in the higher end chocolate that is not present in the more common brands. That is what I would suspect.
