Our approach to preventing egg and peanut allergies has changed over the past 2 decades. At the turn of the century, the American Academy of Pediatrics (AAP) made an expert consensus recommendation that high-risk infants avoid eggs until age 2 years and peanuts until age 3 years. Unfortunately, the ensuing decade saw a substantial increase in self-reported peanut allergy prevalence, rising from 0.4% of US children in 1997 to 1.4% in 2008 . Subsequent randomized trials found that introducing peanuts by age 6 months reduces the risk of developing a peanut allergy by age 5 years, leading to a reversal of the earlier recommendation. In Australia, infant feeding guidelines were revised on a similar timetable as in the United States, with a 2016 guideline recommending that all infants be introduced to peanuts and eggs in the first year of life, regardless of allergy risk factors. A cross-sectional study found that the percentage of Australian infants who consumed eggs by age 6 months incre...
