The first study to map kids' food allergies has found that being
a kid in the city means you're more likely to grow up with food
allergies. According to CBS News, the study looked at 38,500
kids under the age of 18 and found that 9.8% of those raised in
urban areas had food allergies compared to the 6.2% raised in
rural communities. City kids were also twice as likely to have
peanut and shellfish allergies then the rural kids. It's not
exactly clear why children in cities would be more prone to
allergies, but the researchers theorize that it may have
something to do with exposure to a certain environmental
element. So if this sounds like your kid, you might want to do
something about it or they might end up being allergic to
everything.
