New research shows that approximately 8 percent of U.S. children have been diagnosed with food allergies, and more are being treated in emergency departments for anaphylaxis. In the study, “The Public Health Impact of Parent-Reported Childhood Food Allergies in the United States,” researchers surveyed parents of nearly 40,000 U.S. children between Oct. 2015 and Sept. 2016 asking if their children have food allergies. Parents reported on whether their child had ever had a suspected food allergy, if it was physician-diagnosed, specific allergic reaction symptoms and other details about food allergy management. The most common allergens were peanuts, milk, shellfish, tree nuts, egg, fin fish, wheat, soy and sesame. Sesame was the ninth most common allergen and one in three kids with sesame allergy reported at least one severe allergic food reaction warranting an emergency department visit in the previous year.
