A decade after a landmark study proved that feeding peanut products to young babies could prevent development of life-threatening allergies, new research finds the change has made a big difference in the real world.<\/p>\n
Peanut allergies began to decline in the U.S. after guidance first issued in 2015 upended medical practice by recommending introducing the allergen to infants starting as early as 4 months. The rate of peanut allergies in children ages 0 to 3 fell by more than 27% after guidance for high-risk kids was first issued in 2015, and by more than 40% after the recommendations were expanded in 2017.<\/p>\n
