Based primarily on the results of the 2015 UK study LEAP (Learning Early About Peanut Allergy), national guidelines have been released from the NIH and international allergy organizations that recommend introducing peanut in the diet between 4-9 months of age to foster tolerance; once eczema starts food allergy is soon to follow, therefore if the baby has not introduced peanut when eczema begins, a simple skin test or blood test to peanut should be done to make sure they haven’t become allergic and as such would react upon consuming peanut.

If the test is negative, peanut feedings can begin safely at home.  If positive, the patient should see us at Windom Allergy for a simple food challenge.  In the British study, 22% of babies with eczema had a positive peanut test, but only 2% were allergic based on the food challenge.
