I have a ten year old son who has a peanut allergy as well as some environmental allergies and asthma. He was diagnosed when he was two and had an anaphylactic reaction to a peanut butter cup that he had had a bite of. He has only had one reaction as we are very careful with the foods he consumes. He is not allergic to tree nuts or seeds. We avoid all peanuts, all tree nuts and all products that "may contain". He has had sunflower seeds, pumpkin seeds and sesame seeds. I am wondering if anyone knows if pine nuts are a nut or a seed? And are pine nuts related to peanuts? Please let me know if anyone has information on this.

Hmmm, seems to be conflicting information from 2 reliable sites.
I would avoid them until I spoke to my own allergist if I were you.

What about seeds, tropical oils, exotic nuts?
Foods such as water chestnut, pine nut (pignolia or pinyon nuts), coconut, nutmeg do not need to be avoided by nut allergic people unless they are also allergic to these foods. However, allergies to these foods are uncommon. Palm oil and tropical oils do not need to be avoided. Seeds, e.g., sesame, sunflower, poppy, mustard, safflower, canola, do not need to be avoided unless you are allergic to these as well.

Which tree nuts are included in Canada's list of priority food allergens?
The tree nuts of concern are almonds, Brazil nuts, cashews, hazelnuts (filberts), macadamia nuts, pecans, pine nuts (pignolias), pistachio nuts and walnuts. Peanuts are part of the legume family and are not considered a tree nut.

Pine nuts aren't related to peanuts, and experts (such as Dr. Ham Pong whom Susan quotes above) say pine nut allergy is quite uncommon.

But has your son ever been tested for tree nuts? While tree nuts and peanuts aren't related, experts have confirmed to me that about a third of peanut-allergic patients are also tree nut allergic. Even if your son is allergic to tree nuts, pine nuts might be OK. You could do a test separately on that with your allergist. Just bring in actual pine nut to skin-test with.

Even if he's not allergic to pine nuts, though, you're not entirely out of the woods. You'd still need to check labels, probably check with a manufacturer to make sure peanuts weren't processed on the same line as the pine nuts. Might be worth the trouble though - pine nuts are tasty, pesto is lovely on pasta ....

Allergic to soy, peanut, shellfish, penicillin
