Possible Legume Allergies

Hi,
My 20-month old son seems to have developed a sensitivity or allergy to foods he has previously eaten, namely chick peas, green peas and soy beans. He can't keep hummus (chick peas) down anymore, it leads to violent retching. He had soy beans (edamame) for the first time tonight and immediately threw it up. Then approx. 30 minutes later at dinner he ate some green peas, which had been pureed into an asparagus sauce for pasta. He didn't throw up (until I gave him Benadryl anyway, which he promptly threw up), but he developed itchy hives on his face and neck. So, I'm thinking he has developed a legume allergy, which concerns me quite a lot because peanuts are a legume. He hasn't had peanuts yet. The thing is, he can eat soy sauce and tofu (made from soy), which is he even had for lunch today. Does anyone have any experience with this? That is, with legume allergies or late developing allergies or allergies to only certain versions of the same food? I'll call the doctor in the am, but, for now, I'd like to know your thoughts/experiences! Thank you.

What can I do next?

Hi L.,
My grandchild developed many allergies . her WORST outbreaks were about 18-20 months [ summer] and again at age 5/6 year old.
WRITE everything DOWN . log everything , ck his breathing , upper respitory etc ...
Go to DR. / ALLERGIST .. he may not need meds !
the more you are AWARE and write down , the more help it will be to a dr.
Age 5/6 my grandchilds face blew up like a ballon ...that was asap ....ER stuff !!!!!
her allergist [ no daily meds ] stated ,' if a child will live with allergies by age * 6years it will be FULL BLOWN or DISAPATE on it's own.
the dr. was correct .
today she has an outbreak here and their [ seasonal ] a hive outbreak every summer, nothing to be crazy about .... we simply give her ' zertex' as needed seasonal ... as the child grows ; they TELL you of the allergy .. they do know it .
I do recomend going to a dr.

The difference between the peas, edamame and chick peas vs. the tofu and soy sauce is that the latter two are fermented legumes, while the first three are unprocessed legumes. I know several people whose food allergies are muted by fermentation of the allergen (specifically soy and dairy products. Something about how the proteins are altered by the fermentation process.)

Lots of allergies wax and wane, and it does sound like an allergy. Which sucks for you, because legumes are in like everything, and that means a lot of reading labels, buying expensive foods or making things from scratch. But many people get through it, and the soy- and peanut-free aisles are getting bigger at many groceries. And it's good to know that he can still eat fermented legumes, so your options are not so limited as they might be.

Good luck; I wish you all the best!

Get to an allergist and have him tested. Meanwhile stay away from the legumes and stop experimenting as it could be dangerous. My daughter has a severe allergy to peanuts and we didn't know the extent of her allergies and what was making her sick until we went for testing. It ended up being to all tree nuts. Wow, do we ever read EVERY food label. What we also didn't know that with each exposure her reactions increased in severity. Best of luck.

The issue with soy is that it is genetically modified in our country. That means that viruses or bacteria were inserted into the gene to make the plant resistant to herbicides. So not only are these soy beans not natural, they are sprayed like crazy with toxic chemicals. You should get your child checked for allergies. They can test his blood for all the common allergens, including peanuts. Don't risk giving him peanuts until you get him tested. And stay away from soy - the genetically modified giants have ruined that crop for all of us.

L.,

Take him to his pedi and they will be able to do what is best. Allergies can happen at any time. My son is allergic to cashews and this didn't come up until he was 10 (mostly because he generally doesn't eat nuts). If I didn't have a friend with allergies, I wouldn't have noticed it (i.e. no hives, etc.). A good source of information is the Food Allergy Network.

Go to an allergist, but to me it sounds more likely to be the soy he ate at lunch time rather than the peas and asparagus at dinner. Soy is a very common allergen as far as I'm aware. The fact that he had tofu at lunch and then edemame sounds like it was too much for him.

Wheat is another common problem. Are you vegetarian and trying to keep him vege too? If not, try to cut out the soy entirely and give fish and veg for protein. Does he have a problem with dairy?

Hives don't necessarily come up straight away, and what they throw up isn't necessarily the thing that's bothering them - that's the confusing bit. The fact that he throws up hummus might simply mean he's associating it with what he's thrown up before, and this time it sounds like the benedryl might have caused the reaction not the peas.

Try cutting out the soy and other suspicious foods entirely, don't give him any hummus, and then in about a month, try peas etc again one at a time (1x per week) as an experiment.

I don't know anything apart from my own son's sensitivities to milk and other things at first (that he's now growing out of), but I had the help of a kinesiologist which was reassuring and gave me some guidance.

It does sound odd that he could be allergic to peas to me, but just because I've never heard of it before, so what do I know!

I know its hard - what to feed him then? That's what you need some help with - nutritionists can sometimes be helpful.

Good luck.

My son threw up violently to hummus too. It turns out he is allergic to SESAME (tahini is a sesame paste in hummus). Apparently, sesame allergy is becoming more common in the U.S., often showing up in kids who have an allergy to peanuts. But, just because something is in the same grouping, does not necessarily mean you'll be allergic to all of it. For instance, my son eats peas.

Anyhow, give him only safe foods (watch out for sesame seeds on buns and breads) until you see the allergist. Hives on the face, especially around the mouth, and throwing up are sometimes associated with life-threating reactions where breathing can stop. You may want to get a Rx for Epi-pens from you pediatrician to have on hand just in case your son has a more severe accidental reaction to something before you can get an appointment and testing.

My heart goes out to you and your son. I'm not trying to scare you. I hope this is not the case. If you have any questions and would like to chat, just send me an email. We've been dealing with peanut, tree nut, and sesame allergies with my 3 year old son for a couple years now. It's a little daunting at first, but gets easier. He has a great life...we just take a few extra precautions here and there.

Hi L., It has been my experience that some allergies can come and go. One of my daughters began to throw-up pineapples when she was 5...a couple of years later she ate a piece without knowing it and she had no problems with it after that. Another one of my daughters ate grapes all the time, then one night she started to throw-up every time she ate one. That too disapeared after a couple of years. When I was a child I was tested and they told me I was allergic to mustard...again a couple of years later I had some mustard and haven't had a problem with it since. Allergies can also get more sever...I have always been allergic to shell fish (throwing up vicious diarrhea) but when I had a medical test (telling the Doctor I was allergic and what happened to me he dismissed my reaction as "not an allergic" reaction) and he chose to ignore me...and I ended up passing out on the way home from the hospital the next morning (after I told the resident there was something wrong with me)so I was taken to the er, and put back in the very same room I had left just an hour before...my reaction lasted for WEEKS as the iodine worked it's way out of my system. Now I am terrified of what could happen if I'm exposed again! So my suggestion is if you note a reaction to a food wait a few months before offereing that food item again (with no other new foods at least two days before and two days after). Otherwise you could have your son tested by your Doctor. Best wishes.
