The idea of introduction of peanuts early to prevent peanut allergy was radical when it was first proposed. This was the work done by Gideon Lack and published in the LEAP trial which lead to LEAP-ON and LEAP Trio. There were initial thoughts that the prevention may only be temporary and that what we are seeing is just early desensitization and that eventually we will see higher rates of peanut allergy in the early introduction group over time. However, the follow up studies confirm that indeed it is true prevention.
Studies and guidelines encourage early introduction of allergenic foods to prevent food allergy.
