Single nut or total nut avoidance in nut allergic children: outcome of nut challenges to guide exclusion diets


Background:  Children with diagnosed nut allergy are typically advised by health professionals to exclude all nuts from their diets, irrespective of the outcome of allergy testing, to avoid inadvertent contact through contamination or the possible development of new allergies.

Conclusion:  Children allergic to peanuts with negative allergy tests to tree nuts had no co-existing allergy, but were at risk of tree nut allergy where PTs were positive. Children with tree nut allergy were at risk of co-existing peanut or other tree nut allergy whether PTs were positive or negative. Oral challenges to clarify allergy status in all nuts show co-existing allergies even in young children and in so doing may reduce anxiety, minimize unnecessary dietary restrictions and prevent later episodes of anaphylaxis through uninformed exposure. ... x/abstract

Assuming you can find safe nuts with no cross contamination issues. It's probably OK if you buy nuts in the shell, then wash and open them yourself.

The only nuts I can find here with no issues with corss contamination are pistachois, and my daughter doesn't like them.. *sigh*. It's too bad really, because they would be a nice added source of protein!

Our experience is a little backwards from most - my ds is NOT allergic to peanuts, but is severely allergic to tree nuts. Since he tests positive for different tree nuts each time, we avoid all tree nuts (reactions to walnut & pecan, but +ve tests to hazelnut, cashew, pistachio). But peanut butter is a staple in his diet (at home only), and he has eaten and enjoyed peanuts in-the-shell as well. He has accidentally eaten honey-nut cheerios, which the label says contain almonds, and had no reaction. Still, we don't normally include almonds in his diet, even though I've been told that they are also not a "tree nut".

Curious as to that comment about almonds. I've never heard that before - only that coconut is not a tree nut.

My daughter is also allergic to tree nuts but not peanuts. She is definitely allergic to almonds - postive skin prick, RAST and failed the oral challenge.

me: allergic to crustaceans plus environmental
teenager: allergic to hazelnuts, some other foods and environmental
