At the time, nothing could have been further from U.S. standard practice, which cocooned babies from allergens until they were toddlers. But, horrifyingly, in what\u2019s known as <a href=\"https:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMoa1414850\" rel=\"nofollow noopener\" target=\"_blank\">the LEAP study<\/a>, the team discovered in 2015 that this avoidance might have been causing the epidemic of peanut allergy that had engulfed children in the U.S. and elsewhere\u2014children given peanuts in the first months of life were around seven times less likely to develop an allergy to it. Recommendations were revised in 2017, and in October 2025 a <a href=\"https:\/\/publications.aap.org\/pediatrics\/article\/156\/5\/e2024070516\/204636\/Guidelines-for-Early-Food-Introduction-and?autologincheck=redirected\" rel=\"nofollow noopener\" target=\"_blank\">paper in Pediatrics<\/a> revealed that the alteration led to a 43% drop in peanut allergy incidence in the years following.
