I have a theory. Actually I have a lot of theories. But I fear a lot of them would lead to this website being vandalised by web-fascists. But this one is relatively tame. It seems to me that these days there are far more kids around with allergies. Have people just become more aware of allergies? Or is this a symptom of the kind of parenting that means kids are never allowed to play unsupervised and an allergy is perhaps some kind of status symbol? Or are allergies more common than they used to be? I suspect it may be the third option. For a couple of generations now women and girls in the Developed World have lived on a diet of processed food packed with unnatural additives. Is it possible than some of these chemical food additives have resulted in kids being born more susceptible to allergies? Just a thought.
