pHey everyone,/p
pI just finished speed reading old posts on acorns and still don't feel like I have a definitive maybe some other help here?/p
pTeacher asked me today if it's okay for my pa son to use acorns, chestnuts for crafts? I said "I don't know but I'll look into it" so here I am asking if anyone knows for SURE because they have asked their allergist(mine has gone home now)if they pose a risk? My son supposedly isn't tree nut allergic(although he has only ever had almonds/walnuts)and was scratch tested for whatever the most popular tree nuts are(around 8).br /
Thanks guys!/p

I was wondering the same as my dd picked up acorns all around Grandpa's house yesterday! She was fine, but I was going to run it by you all as well.
My opinion, and that is all it is, is that if they are found in nature, and not ingested, and your child is PA only(not tree nut allergic) it is likely to be okay. It is different than nuts processed with others, or like bird seed, where things are in a factory together. Does this make any sense? becca

But, they are tree nuts. So, if a child is TNA they may react to these. Does the teacher really need to use these, or could a non-food item be substituted?

I'm searching for info on these nuts on the net and it lists acorns from a fruit tree.
The net has very conflicting info. on the acorns but yes the chestnuts are listed as a tree-nut.
I'm just going to say no to the acorn and chestnut craft idea since there seems to be people out there allergic to both.
Thanks guys!

This came up at our last Food Education Allergy Support Team meeting to our medical advisor who said to contact FAAN. One of our members did and this is the response:
"Lynn Christie answered this question for an upcoming newsletter...
There is no information in the literature that suggests that individuals with a nut allergy should avoid skin contact with acorns. Acorns are the fruit or nut of the oak tree. Like tree nuts that cause allergic
reactions in some individuals, acorns have a hard shell or outer coating and the "meat" of the nut is inside. Fortunately, we do not use acorns as a part of our diets like the Native Americans did over 400 years ago. The meat of the acorn is very bitter and requires intense labor to make it palatable.
When someone is diagnosed with a tree nut allergy, they may be allergic to one or more types of tree nuts. They are usually counseled to avoid all tree nuts: almond, Brazil nut, cashew, chestnut, filbert/hazelnuts, hickory nuts, macadamia nuts, pecan, pine nuts, pistachios, and walnuts. This is because of the difficulty in determining if one type of nut is
substituted for another in a recipe, cross-contact during processing or shipping, and
unlikely potential of cross-reactivity. These situations put one at risk of an accidental ingestion.
If one has skin contact with the "meat" of the specific tree nut to which they are allergic, they may experience hives or contact dermatitis.
This is very individualized. There were no scientific papers or case reports of
allergic reactions associated with skin exposure to acorns or pinecones. After consulting with my peers, we comfortably recommend that if one has a nut allergy, they should be able to have contact with
acorns or pinecones without risk of an allergic reaction.
Lynn Christie, M.S., is a registered dietitian and clinical coordinator
for the Pediatric Allergy and Immunology Division at Arkansas Children's
Hospital, University of Arkansas Medical Science, Little Rock, AR. She is also a member of FAAN's Program Committee."

Jason is allergic to peanuts and tree nuts, but does not have problems with acorns. He reacts to walnuts and pecans on contact.

My dd is allergic to cashews and pistachios. She is not allergic to the other tree nuts, but she does not eat them due to the potential of developing a sensitivity, and especially due to cross-contamination concerns during packaging. I did specifically ask her allergist if she could handle the acorns and hickory nuts we have in our Michigan woods, and he felt they would pose little danger to her. He gave us the go-ahead to play in the woods and do art projects with them, but emphasized there is no guarantee, and we keep the epi-pen near. She has had no ractions with these nuts.

Chestnuts come from trees but are not true nuts, they are a carbohydrate. The products of chestnuts are used by many people who cannot consume gluten (celiac disease). Peanuts are legumes, they grow in the ground. All that being said, there are those allergic to chestnuts. You may find this abstract interesting
Better to be safe than sorry, but I would have an allergist formally test for individual response. Chestnuts are a good would be great to not have to avoid them, but no one wants anaphylaxis.

My PA child has eaten acorns as part of making Ohlone Indian corn bread at camp and in school several times. It's definitely labor intensive to prepare acorns. He had a lot of exposure several times to the acorn gathering, grinding, washing, etc. Lots of skin exposure and ingestion.
I don't know the details of botanical differences, but tree nuts that are seeds such as walnuts, almonds, pecans don't seem to be the same as acorns, chestnuts and pine nuts. Not to say people are not allergic to these things, but it's they aren't a cross reactive allergen to peanuts for my child.
