Interested to see if anyone has information on two foods not related eg. peanuts and cotton seed oil. From what I have been reading cotton seed oil has the same weight and molecular structure as peanuts.

Very interesting information. It makes a lot of sense. My kids both have pollen allergies and both have had reactions/sensitivities to some fruits and pine nuts.

My daughter is allergic to cow's milk, egg, peanut and tree nut. She is 5 years old and has eaten apples (raw or cooked) without any issue for years. Last spring/summer she started complaining of itchy mouth after eating apples (in raw form). She ate them all winter (raw or cooked) with no issue. This spring started with more intense complaints of itchy mouth and itchy skin (no visible hives) after eating raw apples. Her IgE blood work was positive for apples (lower value, yet positive).

Hi Kara! That sounds like Oral Allergy Syndrome to me. My dd has OAS. I would consult with your allergist to see if cooked apples are okay or if you should avoid.

I am 43, and have some form of Oral Allergy Syndrome. I get small itchy blisters on my lips, roof of mouth, and down my throat, if I eat fresh fruit that you can eat the skin. This started about 8-9 years ago. I can't eat fresh apples, grapes, strawberries, peaches, etc. If you have to peel it, I can eat it. But I'm not allergic to the fruit itself. I can eat most frozen fruits, but not peaches. I believe its the pesticides used on the fruit. I've tried organic, and I get the same reaction.

My son has OAS with apples. His reaction did not occur immediately, but rather almost 12 hours later. I took a picture of his reaction and showed his allergist. Allergist agreed it was definitely OAS. Apparently his reaction was NOT common in that it took so long to show. Just something to think about...

Interesting possibility Eskimomama. My daughter has OAS and reacts differently to different varieties of the same fruit. Sometimes she can eat more, sometimes very little before she feels the reaction. Since it's a cross reactivity to the pollens, it seems to correlate with when the pollen is high or her overall allergy load is high (d/t environmental issues in general). But she reacts to conventional and organic. She seems to be able to eat dried fruits but we haven't really tried frozen.

Wow and THANKYOU I'm not mad or sooking. I starred getting itchy after eating fresh fruit and veg 7 years ago when pregnant, but midwife shurged it off as one of those things. And still have issues now. Had linked it to my reaction to pollens but that's all. So nice to see a reconised reason to what I feel.

Eskimomama4, having any type of food or environmental reaction is inconvenient and frustrating to say the least. I hope it gives you some comfort to know it's actually very common with OAS to react to the skin of fruit but not the peeled fruit inside. Regarding peach, it's a different little beast. According to FARRP because the peach allergen is "heat-stable and highly concentrated under the fruit skin" they recommend avoidance all together. Meaning, sadly, you can't peel it and enjoy like...

Eskimomama, another thought I had was regarding the geographic area in which you live. Chances are you live in an area where there is little or no (for example) birch pollen but the store bought varieties come from regions where there is. Sounds like you should stick to local fruits for sure. Just a thought.

My son has been skin pricked tested 4 times and the last time 3 month ago his tree nut came back negative. All other three skin prick test came back 6+ peanuts & 3+ tree nuts I was suprised when tree nuts came back negative. We still keep him away from all tree nut just to be on the safe side but what are the chances of him outgrowing just the tree nut since he was 3+ before? He is will be 13 in May and is doing great being his own advocate of his allergy and we are very proud of him. We...

In the 1990s I tested big positives to tree nuts and fish. Fast forward to 3 years ago. The same allergist skin tested me for tree nut and fish, and they all came back completely negative. My allergist questioned the results, and had me come back a few weeks later and had the tree nuts and fish skin tested again, as well as did blood work. This second time, my tree nuts skin test and the blood work all came back negative and I can eat them fine. However, my fish skin test and blood work all...

Tina - did he ever have a reaction to tree nuts? Or was that diagnosed on testing alone? Sorry about the school situation - is the school supposed to be nut free?

The one thing that's not stated here is children that are seriously allergic to red dye that is in almost all foods, I have kids that are seriously allergic to red dye and made many trips to the emergency room cause of it, I found that really only organic and all natural foods don't have it and that can be really expensive to buy all the time so making your own foods is best for that one.

Welcome, @Crazy dragon mama ! You're right that it's really hard to deal with a food allergy to an ingredient that's in many foods. We have other folks who deal with "non Top 8" allergies like your family's on our forums ... why not hop over to our Food and Cooking forum and start a topic to share some of your tips and tricks? I'd definitely be interested in comparing notes!

Report: 150% Rise in ER Visits for Severe Allergic Reactions Among Children

Kids With Food Allergies ·
The Blue Cross Blue Shield Association (BCBSA) released a report called Childhood Allergies in America. The study showed that allergy rates among children increased from 2010 to 2016. The study looked at about 9.6 million U.S. with health insurance, ages 18 and younger. It found that 18 percent of these children have allergies. They looked at anaphylaxis (a severe allergic reaction), dermatitis (inflamed skin or skin rash) and rhinitis (runny, stuffy nose).
