Food allergies in kids have dropped by 36% over the past 10 years — a change mostly attributed to a 43% drop in peanut allergies, according to a study published in the journal Pediatrics. Now, eggs have overtaken peanuts as the most common allergen among children. This decrease comes 10 years after a study found that early exposure to peanut products cuts the chances of developing a peanut allergy by 80%. In 2017, the National Institute of Allergy and Infectious Diseases formally issued national guidelines for this early introduction.
“Early allergen introduction works,” Dr. David Hill, the lead author of the study, said to NPR. For the “first time in recent history, it seems like we are starting to put a brake pedal on the epidemic of food allergy in this country.”
Peanut allergies occur when the body’s immune system “mistakenly identifies proteins in peanuts as harmful and releases chemicals that trigger allergic symptoms, including hives, respiratory symptoms” and sometimes “life-threatening anaphylaxis,” said CBS News. Because of this, parents were previously advised to avoid feeding their kids foods likely to trigger allergens before the age of 3.
The current guidelines, updated in 2021, call for “introducing peanuts and other major food allergens between 4 and 6 months, without prior screening or testing,” said CBS News. It “doesn’t have to be a lot of the food,” just “little tastes of peanut butter, milk-based yogurt, soy-based yogurts and tree butters,” Hill said. These are “really good ways to allow the immune system exposure to these allergenic foods in a safe way.” |
