Allergic to Peanuts AND SOY -- All Legumes? - Peanut Allergy Information

Allergic to Peanuts AND SOY -- All Legumes?

Publish date:

My girls (ages 10 and 13) are both allergic to peanuts. But on a lesser level, they are also allergic to soy protein (soy products make their throats itch). They are also allergic on some level to various tree nuts.

As you may know, soy flour is making its way into EVERYTHING lately, which is maddening.

I am assuming that since peanuts and soybeans are legumes and technically in the same "family," my girls may be allergic to ALL legumes, such as various types of lentils. They are positively allergic to green peas, so I keep them away from any type of "pea" vegetable -- even green beans, just to be safe.

But I'm confused about a few foods, such as chickpeas and pine nuts (pinons).

Are there any other people on the board who are dealing with an all-inclusive type of legume allergy? Or a peanut allergy along with a soy allergy? I would love to communicate with you. I have been dealing with this in total isolation for many years.

My DD (22 months) is allergic to soy & peanut as well as milk & egg. She also has reacted to green beans. She is actually going to the allergist tomorrow and I am going to talk to him about what all we need to avoid. I'm not sure what all he will test for, but I've been avoiding giving her any legumes since the green bean incident. There are many others on this board with the same situation. You are not alone!

I'm not up to speed on some of the abbreviations. What is a DD?

Anyway, I thought that green beans were not a legume, but I'm really confused about it. Chickpeas also -- legumes or not?

My youngest ate and loved green beans before she developed her peanut allergy at age 6 (after accidently taking a bite of a peanut butter cookie). She ate green beans a few times since being diagnosed with the peanut/legume allergy and had no reaction. Now that she's older (age 10), she will not touch green beans -- she's too scared to eat them. And since I'm unclear, I side with her.

It's so confusing....

(DD=Dear Daughter)

It is confusing...but you will find so much info on these boards. I recommend you use the search option. My dd has the same allergies as yours (PA, Soy, and TNA). She has a history of anaphylaxis and has asthma. We strictly avoid peanuts and treenuts. Soy not quite as much. She tested a Class 3 but doesn't seem to react unless it is listed in the top 3 or so ingredients, thankgoodness! You are right soy seems to have snuck into everything! As far as chickpeas and lentils...hmmm....I don't give them to my daughter either but to my knowlege she has not tested positive to them. But we do avoid for some reason. Like I said, if you use the search feature, you can find old threads that may prove useful to you.

Thank you for reminding me about the search feature. I will be spending a lot of time here researching things.

I have been dealing with this in total isolation for almost 13 years. It's a relief to find some support!

My dd was diagnosed 8 yrs ago and I didn't find this site until @1yr ago. Wish I would have found it sooner. You are not isolated anymore [img][/img] Happy searching!

Green beans are a legume but from what I understand (and that is very little these days) is less likely to be allergenic. Of course, as you probably know, you can be allergic to anything.

My son (22 mo) is allergic to soy and peanuts. We are avoiding peas until we test for them this week. We have slowly and successfully introduced other legumes - black beans, chili beans, white beans & green beans. Something about peas scares me though - guess I read one too many instances of those with soy and peanut allergies having bad reactions. He is not of an age where he can really tell us if it bothers him, usually manifests itself in major hives.

I commend you for allowing your daughter dictate what she does and doesn't feel comfortable eating. It is really hard for us as we were told to eat our vegetables growing up. I was a good eater, but my brother was forced to sit at the table for many a night until he finished his vegetables. I learned the hard way that if I push, it's usually going to end badly.

I had issues with bananas growing up. Everytime I ate them, my throat would become itchy for longer periods of time. I finally gave up eating them (though I loved the taste) because it just wasn't worth it to me. As an adult, I was mistakenly served banana nut pancakes and went into anaphylactic shock after just a few bites. My heart knew it would be bad if I ate them again (prior to the anaphylactic reaction) - does this make sense?

The soy is annoying. I think honestly I find it more annoying than the nuts. Actually it's gotten to the point that nuts are the last thing I read for on an ingredient list. We are also trying to avoid soy lecithin though even though I have heard conflicting reports on whether or not it helps. Unfortunately the lecithin is not usually bolded or listed as a "contains soy" as the oil is not supposed to contain the protein which many are allergic to. We are possibly on the cusp of outgrowing a few of his allergies and hoping that my strict avoidance has helped. All in all it has forced him to eat healthier (which has also been a benefit for us and my mother in law who lives with us). I sometimes do wish he could eat more though as it's a constant struggle to keep weight on him.

Keep plugging - it's hard, almost impossible to understand sometimes, but our kids will benefit from all the knowledge we can obtain to keep them safe!

I would agree with avoidance.

From simply a PA (peanut allergy) perspective, though, I would stay away from pine nuts. My DS is PA and a little soy allergic, but we stay away from pine nuts because a) he hasn't been tested for them (he has been tested for some tree nuts and can technically eat them if we shell them or if we know they're processed by a company that does no other nut at all [he can have walnuts and pecans, but I wouldn't buy pecans from someone who also does walnuts--only pecans--just my comfort zone--and he only has them every once in a while]) and b) of cross contamination (you might see that has cc or xc here). I haven't found dedicated pine nuts. I don't know how to buy them whole. So we haven't had him tested. We can make a pesto w/o them.

So--that's just my take. If you're having a hard time with other legumes, that, to me would be the first reason to stay away--but cross contamination concerns would be the second.

Jason used to be allergic to peanuts and soy, but he recently outgrew the soy allergy.

We didn't avoid the rest of the legumes. He never had a problem with other legumes.

My son is allergic to all legumes and lentils. According to Dr. Sicherer, this is actually fairly rare - about 1 in 20 for children who have a peanut allergy. Dr. Sicherer postulated that he was allergic to a protein in the seed pod that is shared in common.

When he was younger (<4), he used to be able to eat some beans and peas including chick peas, fresh green beans and snap peas and garbonzos. However, he developed allergies to all of these around 4.

He's now 11 and is still allergic as far as we know. There are a few beans he can tolerate, like carob. He now eats nuts other than peanuts without a problem. He has had anaphylactic reactions in the last few years to soy, so we know this is still a problem.

Let me know if there's anything specific you're wondering about, as my DH and I may have run across the answer over the years. We have so many books on food additives that our bookshelves look like we're chemists.

My 13 month old son is allergic to peanuts, soy and all legumes (as well as egg and dairy). I would probably stay away from the pine nuts and chick peas (garbanzo beans) as they are in the same family.

I agree about the soy being in everything. It drives me crazy. I think I've found something for my son to eat and then I find out it has soy in it.....


On Nov 28, 2006

One thing I find very confusing is: what is a legume and what is a bean? I know that technically legumes come in seed pods (peanuts, green peas, soy beans). But without being an agricuturalist, how do you know if a certain bean is technically a legume? I have a list, but I'm always afraid I've missed something.

OK -- like Tamarind. In Indian restaurants they have tamarind sauce. Tamarinds come in pods. Are they legumes?

My kids seem to be able to eat pinto beans and black beans (the type served in Mexican food). So I suppose that those are "just beans." My oldest daughter tolerated hummas when she was a toddler, but since I found out that chickpeas might be a legume, I won't let her near it.

But in the same breath, I say that my girls have eaten something in Indian restuarants for years I later found out is made with chickpea flour. So maybe they ARE OK for her and her sister.

I was actually thinking of writing to a chef or a cooking school (or an agricultural expert) to find out for sure.

It's so funny how people are surprised when I tell them that my girls are allergic to peanuts and soy. "Soy too?" they ask incredulously. Then I explain how peanuts and soybeans are both legumes, technically in the same family. I think that people think of soy as some other type of food -- tofu or soy sauce -- and don't think about the "bean" in the word "soybean.

We have had trouble with soybean oil....don't trust it. Also, chickpeas or garbonzo beans are poison to my peanut/legume son.

On Nov 28, 2006

My son at one time did NOT react to soy when he was much younger. He reacts at the highest level for peanut on the RAST tests, and now is nearly the same for soy! There are no hard and fast rules on outgrowing an allergy, but always remember that things can become worse unexpectedly!

I'm severely allergic to soy and have a tag-a-long peanut allergy. I'm fine with other legumes. I eat green beans, lentils, other beans, licorice, mesquite, alfalfa. . . you name it. Rooibos tea is a big fave of mine--also a legume.

I do try to stick with dried beans and lentils. And ALWAYS sort. I often pull soybeans out of bags of dried beans (along with rocks, sticks, grains, and other things which don't belong). If you eat grains, always sort those, too.

I react to soybean oil and lecithin and soy-derived vitamin E.

Whoa! You named a bunch of foods I would never have associated with peanut/legume allergy! Licorice? Mesquite? Alfalfa? And...I never knew that Vitamin E could have soybean oil in it. Does that go for other oil-based vitamins, too? My kids are not allergic to soy lecithin or soybean oil or soy sauce (because, I presume, there is no protein in those).

On Dec 1, 2006

The foods I named are legumes. There are tens of thousands of legumes. It's one of the largest plant families. You may only react to pulses/beans, though.

As far as vitamin E/tocopherols, vitamin E is frequently derived from soybean and carried in soybean. Another natural source is wheat germ. Yet another is sunflower. It can also be synthetically derived.

There are proteins in soybean oil, soy lecithin, and soy sauce, but they may not be the proteins you react to or there may not be enough for you to react. There are medical studies showing some soy allergic individuals do react to oil/lecithin.

Well add our names to those allergic to peas. Something in my heart would never let me give it to my son even though I covered just about every legume. Always passed on the pea. We had a positive SPT on Wednesday.

No peas on earth for us LOL

My DD is 4 1/2. She is allergic to peanuts, tree nuts, sunflower seeds, sesame seeds, buckwheat, coconut, cinnamon, wheat (anything with gluten), egg, latex, avocado, bananas, and apples. She used to eat other legumes with no problem, but now seems to have developed an allergy to peas and pinto beans. I have an appointment with her allergist soon, but don't know at this point if it is safe to feed her other legumes. :(

My 6 year old son is also allergic to peanuts and tree nuts, but has never reacted to other legumes.

I am allergic to peanuts, tree nuts, and soy (developed later) as well. For me, I've determined that I only react to soy when it is either in a pure form (soybeans, soy milk, etc) or listed as "soy protein concentrate" and not in any other form so far. Soy flours and oils have not been an issue, thank goodness, since they are in everything now. I also cannot eat lentils, as they give me a scratchy throat. However, I can have chickpeas with no problem at all along with all other types of beans. I've read in the past that a soy allergy is quite common in those with peanut allergies, as their protein structures are very similar and cross reaction is common. Feel free to PM me any time with questions! You shouldn't have to navigate the allergy world in isolation.
