I also thought that exposing my daughter to the soybean oil and soy lecithin was OK but, instead of HELPING her to outgrow it she is MORE severely allergic NOW after 2 years of her eating things with soybean oil in it. [img]http://uumor.pair.com/nutalle2/peanutallergy/frown.gif[/img] The allergist told me that she was so mildly allergic at the age of 2, that by the age of 3 or 4 that she should have outgrown it! WRONG!!! She is more allergic now and her Dr. feels it is because I exposed her to the proteins that we thought was OK for soy-allergic kids.

With Jason, the soy allergy (mild to moderate) came before the peanut allergy (severe, but yet to experience an anaphylactic reaction to peanut *touch wood*)

Maddiesmom, I know you said that your daughter's numbers for soy had gone up after only exposing her to oils/lechithin, but was she showing signs of a reaction to soy prior to the testing? I ask because as I stated earlier, my daughter's soy allergy increased when we gave her soy milk and she showed physical signs of reacting - eczema flare - but once we stopped giving her obvious soy protein sources, but continued with oils and lechithin, she does not appear to have allergy reactions from soy. My hope is that she is outgrowing it as she did with milk. On the other hand, your situation worries me that giving her any soy could make her numbers worse. Thus, Maddiesmom, that is why I wanted to know if your daughter seemed to react? Thanks.

My son is allergic to peanuts, nuts, some legumes and soy. He does not appear to react to soy lecithin or soy oil and enjoys them frequently. I imagine this is due to the fact that soy lecithin is generally one of the last items listed, and thereby contains a very small amount.
To make sure I understand what the theory being put forward, let me repeat what I think I'm reading:
Even though there are no visible reactions or signs to ingesting soy lecithin and oil, if a child is allergic to soy, then prolonged exposure to *any* soy products, may make the reaction to an accidental dose to a more dense source of soy (soy sauce, or flour,)more severe?
Have I interpreted correctly?
If this is true, or even might be true, this is very concerning and is definitely something I need to research further.

A newspaper article which raises the question about the link between soy and peanut allergies:
Peanut allergies vex researchers
Reactions rare in Asia, climbing in West

The Chinese cook them with chilies in kung pao chicken, and Thais shower them over the tamarind noodles of pad thai. But peanuts rarely provoke allergic reactions in Asian countries, though those are among the world's top producers and consumers of the increasingly troubling legume.
While research efforts to battle peanut allergies intensify, scientists are still stumped to explain why the numbers seem to be ballooning in Western countries while holding low and steady in the East.
Hugh Sampson, a leading pediatric allergist at Mount Sinai School of Medicine in New York, noted this week that "China has virtually no peanut allergy cases."
The numbers are similarly skimpy in countries like Thailand and Singapore, where peanuts are also pillars of the local diet.
Researchers suspect that the disparity may in part reflect the fact that Eastern cuisine uses boiled or fried peanuts, while peanuts in the U.S. are typically roasted, said Dr. Sampson, whose Mount Sinai colleagues recently investigated the issue.
They concluded that roasting uses a higher temperature that seems to increase the allergenic properties of a peanut, allowing its protein to bind more easily to the IgE antibody that triggers the intolerant reaction.
More than 150,000 Canadians are estimated to suffer from peanut allergies, as are 1.5 million Americans, numbers that seem to have soared in the past two decades.
No Canadian studies have documented the incident rate over time, but it's likely to be similar to data collected elsewhere, said Karen Binkley, an allergist and clinical immunologist at St. Michael's Hospital in Toronto. A British study published last November, for example, found peanut allergies have tripled since 1989, to 3.3 per cent of children.
The report, echoing a Canadian finding in 2001, also suggested that eating peanut products while pregnant or breastfeeding contributes to the increase.
But this week, a study by Gideon Lack of Imperial College in London, England, found no such link. His report, published in the New England Journal of Medicine, concludes that use of topical lotions or ointments that contain peanut oils, either by nursing mothers or on infants with broken skin from diaper rashes or eczema, is a significant contributor to peanut allergies.
Jane Salter, president of Anaphylaxis Canada, an education and support group for people with severe allergies, said that with so many possible explanations and no definite answers, "I wonder if we are chasing after cures instead of chasing the root causes."
Dr. Salter, whose daughter has a peanut allergy, said she would like to see further investigation of Dr. Lack's finding that an infant's exposure to soy products in the first six months of life may also increase the risk of peanut allergies.
Although an allergy to peanuts does not imply an allergy to soy, the two legumes do share a similar chemical structure. Theoretically, soy may trigger an immune-system response that contributes to a peanut allergy.
And soy, Dr. Salter noted, has been part of the Asian diet for thousands of years, yet prevalent in Western food only in recent decades. She noted that soy is found in both cattle and chicken feed, and in an array of different food sources.
Four-year-old Dana McNeil, who has a severe peanut allergy, was six months old when her mother switched her to a soy milk formula after finding that cow's milk upset her stomach. "She was on soya for a few months," said Karen McNeil, of Pickering, Ont. "Now this really makes me think and wonder if this had anything to do with triggering the allergy."
Dr. Binkley said the increase in peanut allergy rates despite the relative immunity of Asian countries is not likely to be explained by a single factor.

Bootsy- My daughter had mild reactions to soy from birth. She was breastfed till 4 months old, then I gave her milk based formula which she vomitted from. I then switched to soy based and she got exzema. I then put her on Aulimenten (spelling?)and she was fine.
At 18 months she had a severe reaction to pn and we had the whole allergy test done. Showing soy, milk, wheat, peas, pn, tn, egg allergies. She outgrew all of them put soy, peas, pn and tn by the age of 2. At that time they told me because her soy #'s were low and the skin test only showed her mildly allergic, to stay clear of soy flour, soy proteins, and soy products. BUT that any product with soy lecithin and soybean oil were OK. As I said above, she seems to not have any reactions from the soy lecithin and soybean oil. Life seemed good for once. UNTIL 2 weeks ago when we had her retested and she is more allergic to soy now. Her numbers have more than doubled.
I understand your confusion and concern because I am equally confused about the whole thing. We have been completely SOY free (no lecithin or oil) for the past 2 weeks, and it has been very difficult, but hopefully in a year when we have her retested, her allergy will have gone down or at least stay the same. My allergist and I hope that if we stay clear of soy products all together that she has a higher chance of outgrowing it.

Maddiesmom - thanks for the information about your daughter. Our stories seem very similar. I will post when we have dd retested, probably in September, for soy. Since she has not been reacting, I have assumed that the oil/lechithin would not be increasing her numbers, but it seems that may not be the case. Thanks again. Bootsy

My son was initially allergic to all treenuts, peanuts, soy and eggs. We he had soy formula (at 5 months), he vomited violently -- all night...but we did not catch on until later (we just thought he was sick). Then we put him on Nutrimagen (with soy oil) and he was fine. When we introduced tofu (at 12 mos. to add some protein to his diet)and he vomited violently again. Then we knew it was soy, and he tested positive.
At 2.5 years, he tested negative and we reintroduced soy. He seems fine with it now (though I have never given him large amounts). While he was still allergic he consumed lots and lots of soy oil and lethicin -- with no problem at all.
Interesting while pregnant with him I drank calcium enriched soy milk...never milk. He was allergic to soy, but never milk. We practiced strict avoidance with milk once we saw his allergic tendencies (in my diet, I was nursing, and in his) but he was never allergic to milk! My next pregnancy I drank milk, and very little soy and my second son was allergic to milk for the first year of his life!

I posted under another topic and then noticed this one - I have a 3 year old who is PA, a 5 year old who used to get eczema from milk protein and now I have a 7 month old who I've only breastfed so far. I was thinking of supplementing but now that I've read all this about soy, I'm not sure I will! I nursed my PA son for 9 months then went to soy formula since I (from 1 year of age) get eczema from milk and my older son did as well. I never knew formula was milk-based until the first time I gave it to my oldest son at 5 months when I had a medical procedure done. He flared up all over. Whenever I supplemented from then until I weaned him at 11 months, I used soy formula. I had planned to do the same for my third son but I keep reading about the possible link between soy and PA! Wouldn't it be great if they discovered what caused allergies, found their cure and then eliminated them from the future ? [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img]
I haven't given my baby formula yet but was trying to research Nutramigen or any other non-milk, non-soy. Any problems or suggestions anyone can offer? I have avoided all peanut products since my 3rd was born but I ate peanut butter while pregnant (wish I had discovered this site earlier!) I told my son's allergist about this site and the useful information it contained.
I just don't know what to do about introducing formula. I want to nurse as long as I can but with 3 boys [img]http://uumor.pair.com/nutalle2/peanutallergy/smile.gif[/img] it gets harder each day! But I want to do everything I can to avoid sensitizing my littlest one...
