Childhood Food Allergy Prevention Advice: What the New Studies and Medical Guidelines Teach Us

Childhood Food Allergy Prevention Advice: What the New Studies and Medical Guidelines Teach Us

By Katie Marks-Cogan M.D.


There is groundbreaking new research that’s changing the way allergists look at childhood food allergy prevention. Unfortunately 1 in 13 children in the US now suffer from a food allergy.  Thankfully, findings from these recent landmark studies have shown us that a baby’s risk of developing common food allergies can be reduced by up to 80% through early and frequent exposure to allergenic foods.

Here are my 5 lessons for early allergen introduction to help reduce your infant’s risk of developing a food allergy based on this breakthrough research: 

  1. For infants with eczema, consult your pediatrician first: Infants with eczema are at the highest risk for developing a food allergy, however a discussion with your pediatrician is required before introducing any allergenic foods.  
  2. Starting early: Studies show that there is a critical window starting around 4 months to introduce allergenic foods. In fact, delaying introduction may put your child at a greater risk for developing a food allergy.  
  3. Only introduce when it’s best for baby: When planning to introduce allergenic foods, choose a time when baby is healthy and a parent/caregiver can monitor for any signs of an allergic reaction for at least 2 hours.   
  4. Start with a small dose, then gradually increase: The approach of one landmark study suggests that stepwise introduction (starting with a small dose and increasing to a higher dose) was a safe approach to introducing allergenic foods.  
  5. Sustaining exposure: Continuing exposure to allergenic foods for several months is critical to reducing your baby’s risk of developing a food allergy.  In fact, several landmark studies exposed infants to allergenic foods 2-7 times/week for 3-6+ months.


While this latest research on food allergy prevention is exciting, I’ve also seen many families struggle to comply with the new guidelines - particularly with sustaining exposure.  As a mom of two, I understand that getting a 4-11 month old to eat anything on a consistent basis is challenging given that most infants are picky eaters. That’s why we, along with a team of leading medical experts and inspired parents, developed Ready, Set, Food! so that parents everywhere can feel confident giving their child the best head-start towards an allergy-free future.

We’re proud to tell parents that Ready, Set, Food! is not only based on the dosing in the landmark clinical trials, but also is organic, non-GMO, and does not contain any added sugar or other additives.  Learn more about how Ready, Set, Food! can make lowering your child’s risk of developing a food allergy easy and all-natural here.
