In this new series of NNI Bites, Big Learnings, we are featuring episodes covering the NNI & WNSC Workshop 103. In this episode, Dr. Yvan Vandenplas speaks with Dr. Rosan Meyer about how early complementary feeding practices shape food allergy outcomes in infants. Dr. Meyer highlights that a four-to-six-month window of opportunity exists for allergen introduction — with evidence from the LEAP and EAT studies showing that early introduction of peanut and egg significantly reduces allergy risk — while also emphasizing that introduction before four months offers no benefit and may be harmful. She further encourages a holistic approach to complementary feeding that prioritizes dietary diversity across different food groups, culturally appropriate foods, and enjoyment — rather than focusing solely on allergy prevention.
