Cracking the Peanut Allergy

Every three minutes, a food allergy reaction sends someone to the emergency room in the US. It's an alarming statistic that worries parents and adults across the nation. In some extreme cases, mere nanograms of peanut protein can trigger a dangerous reaction and a mad dash to the hospital.

The US Center for Disease Control reported that from 1997 to 2011 the number of children with food allergies increased 50 percent. Over 15 million Americans suffer from food allergies, at a cost of $25 billion each year.
