#129: Exploring the Eczema & Food Allergy Risk Link with Rebecca Hartman, MD MPH
🎧 Listen to this Episode
📝 Episode Description
If your baby has eczema, you may have heard that it could increase their risk of developing a food allergy. But what does the research actually say, and what should you do when you’re introducing allergenic foods?
In this episode, I sit down with board-certified dermatologist Dr. Rebecca Hartman to unpack the connection between eczema and food allergy risk. We talk about why the skin barrier matters, how eczema severity affects risk, what signs of an allergic reaction parents should watch for, and practical ways to care for your baby’s skin while starting solid foods.
If you’re feeling nervous about introducing foods like peanut or egg because your baby has eczema, this episode will help you better understand the evidence and leave you feeling more confident about your next steps.
