I don't believe in them. When I was a kid we all went to birthday parties and ate cake and ice cream. No one was lactose-intolerant, no one got spelt cake, or whatever, because they were allergic to gluten. Kids ate PB&J for lunch, just like their parents did. I just can't believe that in a single generation we've gone from largely omnivorous to wildly limited in our ability to digest food. Allergies are usually imaginary and I don't approve of them.
