The number of kids who were treated for food allergies rose 18 percent between 1997 and 2007. Whether this represents an actual increase or is simply the result of people knowing more about food allergies and seeking treatment is unknown. But healthcare providers report the number of children seeking treatment in emergency rooms for allergy-related symptoms has tripled since 1993, and about 4 percent of all children are reported to have food or digestive allergies. Food allergies can be life-threatening for children. Common culprits include peanuts, tree nuts, milk, eggs, soy, shellfish, fish and wheat. If you think your child has a food allergy, talk with your pediatrician.
