When it comes to allergies, new research suggests where you grow up matters and Americans, in particular, have it bad.
FOX's Colleen Cappon has the reason why in today's "Housecall for Health":
New research suggests where you were born can increase your risk of allergic disease, specifically the United States. A Northwestern University study surveyed 80,000 children and found that kids born abroad are half as likely to develop asthma and allergies.
Researchers say the reason may be the hygiene hypothesis, which suggests U.S. children are too clean and their immune systems don't get exposed to common allergens.
