Peanut Allergy Experiment in Young Children

Description

In the late 1990s, it was believed that young children should exclude peanuts from their diets to reduce the chance of developing an allergy. In 2008, researchers were no longer so sure. This experiment evaluates whether peanut exposure is helpful or harmful. A peanut diet regimen (consume or avoid) was assigned to over 500 young children during years 2-5, ages during which children had previously been told not to eat peanuts. The key outcome was testing for a peanut allergy when each child turned 5.
