Earlier this year, reports emerged about a new study which would offer hope to children suffering from peanut allergies. Many parents get conflicting information as to when to introduce nuts to their child and how to detect if they're allergic to them. Today, Parents Ask expert Dr. Cara Natterson answers some of these common questions and concerns.

Q: At what age can I introduce nuts to my child? What are common/typical allergic symptoms/reactions? What is an ideal order of introducing nuts? (Almonds before peanuts? etc.)

A: Until 2008, the AAP (American Academy of Pediatrics) recommended waiting to introduce peanuts and tree nuts until age 3. But in 2008, they changed their stance. Dr. Frank Greer, MD, Chairperson of the AAP’s Committee on Nutrition was quoted as saying: “[Waiting] makes absolutely no difference. For instance, if you are going to have peanut allergy, it has nothing to do with when you were introduced to peanuts. If a mother eats peanuts during pregnancy or lactation or if she feeds her 6-month old peanut butter, it has no effect on whether you get peanut allergy. If you are going to get it, you’re going to get it.” That said, most pediatricians (myself included) do not recommend peanuts and tree nuts in the first year or two of solid food eating, especially if there is a family history of allergy. Symptoms of allergy can range—including mild stomach upset, rash (anything from splotchy to hives), swollen lips, coughing, even vomiting. The Food, Allergy and Anaphylaxis Network website (www.foodallergy.org) has terrific guidelines for parents about what allergic reactions look like and when you need to worry.
