Living in U.S. raises risk of allergies

“Children born outside the United States have a lower risk of asthma, skin and food allergies, and living in the United States for a decade or more may raise the risk of some allergies, said a study Monday. The research in the Journal of the American Medical Association suggests that certain environmental exposures could trigger allergies later in life, overcoming the protective effects of microbial exposure in childhood.  The study examined records from 2007-2008 phone surveys of nearly 92,000 people in the United States, where food and skin allergies have been on the rise in recent years.”
