If you've worked with kids lately, or if you're a new parent yourself, then I'm sure you know all about this epidemic of food allergies. According to a 2011 study, 8% of American children under 18 have at least one food allergy, and that is up from 4% in 2009 (
1). Peanut allergies in particular have been on the rise. In one Midwestern county, the prevalence of peanut allergies in children
tripled between 1999 and 2007 (
2). But you don't need numbers to realize it's a problem. Just spend a day in a school cafeteria. Or a summer camp. Just enter an elementary school classroom at all and you'll hear about it; the concern is clearly growing. Dairy may be the most common allergy, and it seems kids can have a reaction just looking at a peanut, but there are others to worry about as well, including wheat, eggs, soy, tree nuts, fish, and shellfish.
But it wasn't always this way. When I was a youngster, I don't recall ever hearing about another kid having a food allergy. Maybe the most I ever heard was that a classmate was lactose intolerant. But there was no mention of peanuts. Nobody had a wheat allergy. Nobody went into anaphylactic shock at the mercy of a pistachio. So what gives?? Why are food allergies exploding?
Well, sadly I don't think we know the answer to that question. Much has changed in the food and health world over the past few decades, so we have many likely culprits. Over these next few posts, I'll be exploring the options, in a sort of thinking-out-loud fashion. Excuse me if what follows turns into an incoherent mess.
