-first do no harm. And then feed peanut.

The -- were developed to build on previous food allergy guidelines after several key studies demonstrated the benefit of early introduction of allergenic foods. These landmark studies including the Learning Early about Peanut (LEAP), LEAP-On and Enquiring about Tolerance trials created a paradigm shift in food allergy prevention. The "take home" messages of this guideline include that peanut should be introduced early in the first year of life, and for the majority of infants, peanut can be introduced at home. The only group of infants for which medical assessment is recommended is those with severe eczema, egg allergy or both. Here we summarize the Guideline recommendations, endorsed by the Canadian Society of Allergy and Clinical Immunology, and highlight important aspects relevant to Canadian practitioners.
