Are Walnuts Highly Allergenic? (more). . .

Are walnuts highly allergenic? This morning my 2 year old son (who has not been shown to be PA, although my 5 year old daughter is PA) had an allergic reaction. The only thing I did differently was put flax seed oil & walnuts in the waffles. My son ate breakfast berfore I did (cereal) so I'm not even sure he took a bite of his waffle. He seemed to want a waffle so I got him a plate & handed him a piece, but he didn't seem interested (which is why at the time, I didn't even think he took a bite). Then I ate & didn't really pay attention & he ran off to play. Shortly afterwards, he was crying & rubbing his eyes & they were swelling shut & his face & neck were red & blotchy with some hives on his forehead and his ears itched. I gave him benadryl & called the nurse advice line, and he is doing much better (just a little swelling left). But I really wonder what brought it on. And I'm nervous about the severity. Looks like it's time to see the Dr & allergist again & get more Epipens (I really hoped my son wouldn't have bad allergies!). Any info or thoughts greatly appreciated.

Hi,

Sorry to hear about the reaction. Many people who are allergic to peanuts also are allergic to tree nuts (ie: walnuts, pecans, etc...)... So you should have your child tested..

I am lucky in that I am only allergic to peanuts. But I still try to avoid tree nuts due to the possiblility of cross-contamination (ie: the production line used to package walnuts may also be used to package peanuts, so traces of peanuts could appear with the walnuts).

So I recommend avoiding all nuts, and go to an allergist for testing too. Best wishes.

Yes, I think that walnuts are highly allergenic! I find it upsetting that your allergist didn't warn you about this in the first place. The AAP reccomends that children with a family history of allergies avoid all tree nuts until age three. My own daughter is allergic to both walnuts and peanuts. We have not tried any other nuts but have been advised to avoid all of them. Tree nut allergies tend to be as severe (potentially life threatening) as peanut allergies are, and also to be life long. I have also met a number of adults who have developed walnut allergies as adults. Good luck, and at least you are already prepared. Take care, Miriam

my daughter is PA and just skin tested positive for cashews (but NOT walnuts or almonds). Funny, as her CAP RAST for all the nuts was NEGATIVE, including the PEANUT (but skin tested a 4+ for peanuts and 3+ for cashews). We are avoiding all tree nuts at this time. I am going to have her CAP RAST tested again for peanuts at age 5...as I am having a hard time understanding why is is a NEGATIVE CAP RAST for peanuts, but a positive skin test...I almost want to have her food challenged, but won't press for that at her age of 3....

I think that I read somewhere that 30% of PA also have TNA, and among TNA's walnuts are a leader. SO I would say yes, walnuts are highly allergenic. Sorry you are having trouble with them. Aside from the loss of protein, they aren't too hard to avoid if you are already dodging peanuts though. Note: lots of frosted cereals used almond paste, including some made by General Mills- it is close to the bottom of the ingredient list.

My son has been tested for a few tree nuts (walnuts, cashews, pecans, almonds) and walnuts were the worst. He is questionably allergic to almonds, but we avoid them like everything else. (He is also PA.)

Take care, Tammy

I,m PA/TNA, but seem to be worst with almonds. I have had a known walnut reaction, but it didn't seem as bad.

Thank you so much for your very informative input!! It was extremely helpful and very EYE OPENING!! (Would you believe that the Nurse on the advice line for Oakland Children's Hospital didn't think that walnuts were very allergenic? There's a lot to be learned in the health care field about allergies!)

My son is VERY allergic to walnuts...and he has never eaten them...we saw his first and second reactions (the first time we did not figure it out) from simply TOUCHING walnuts and touching him! He had mysterious hives (just one or two) for months, and bad eczema (from what I was eating...I was nursing). Then one day when he was 6 months old I held him after crumbing walnuts on a salad...he broke out in hives wherever I touched him (it was so dramatic we took photos to show the doc). At that point we did not make the connection. Two weeks later, my parents put walnuts on a sundae and then held his hands to help him stand...he broke out in hives all over his hands...then we figured it out.

I would hate to see what happened if he actually ate nuts, but he is VERY allergic to walnuts. Did you touch the walnuts and then touch your son?

My father in law is allergic to walnuts (all tree nuts). He has had two anaphylactic reactions that I know of and ended up in the emergency room. He is not allergic to peanut.

Definately, see an allergist. Tree nuts can be just as bad as peanut.

My son actually touched the waffle with walnuts in it, but at the time, I didn't think he took a bite because he pushed it away and then threw a fit (he's 2) while I ate. Immediately after that, he broke out. I sort of hope he took a bite, because if he broke out like he did just from touching it, THAT'S SCARY! (But from your stories, I can see that he may have just touched it). --Amy
