it's the pseudoscientific "doctor" bit that's the problem though. People are thinking there's a genuine medical problem. And rather than asking their own, medically trained GP, they're taking the TV quack's word for it. (Then they come to people like me and try to use the TV quack's generalised information as wisdom which they are convinced will magically cure my disability, and get all huffy when I tell them no, I don't have any allergies, I'm just ill.) When I was at school I would go to a friends' house afterwards or someone would come back to mine and we'd have a sandwich and our mums would have a cup of tea. Now a friend of mine with a school-age kid can only do that with about two friends, because the mums watching the "doctors" on daytime tv have a medical reason for their kiddies to not eat a sandwich because they can only have "special" bread and no margarine and a particular brand of cheese. Healthy eating, as in plenty of fresh meat and vegetables and less overprocessed McFatMeals(tm), sure. But what we're getting here is a load of neurotic, obsessive packet-checkers who think it's somehow trendy to have an allergy.
