If you’ve been to a children’s birthday party lately, chances are at least one of the little guests had a portable needle loaded with epinephrine. Its standard equipment for a growing generation of highly allergic kids: more than three times as many children have food allergies now than twenty years ago. And one out of every three children is now allergic to foods, animals, or plants. Something puzzling, and frightening, is going on with our immune systems. The Allergy Fix travels across Canada and to the US, the UK and Germany to investigate why allergies are on the rise – and what’s being done about it.
