We are thrilled to have Dr. David Stukus back on TRC! He tells us what the science has to say about introducing allergenic foods into an infant’s diet plus he answers some checker’s questions. Dave is a pediatric allergy and asthma specialist at Nationwide Children’s hospital. He’s the social media medical editor for the American Academy of Allergy, Asthma and Immunology and a member of the Joint Task Force on Practice Parameters. He is an author, podcaster, and a strong advocate of science based-medicine on Twitter.
