Dear AllergyKids’ Friends,
Soy Induced Anaphylaxis in Children with Asthma and Peanut Allergy
As many of you know, soy is one of the top eight allergens. What you may not know is that a child with a peanut allergy can have an allergic reaction after eating a food that contains soy, according to the Asthma and Allergy Resource Center.
How could soy cause an allergic reaction in my child with peanut allergy?
In scientific terms, soybean allergens are “homologous” to known peanut allergens and can be recognized by 44% of peanut-allergic patients.
What that means is that a child with a peanut allergy can have an allergic reaction and even go into anaphylaxis after eating soy. Because this cross-reactivity is rarely mentioned in the press, many parents are unaware of the potential health risks that soy may present to children with peanut allergies.
What are the Signs of a Cross-Reaction to Soy?
According to Ingrid Yman, PhD of the Swedish National Food Administration, these deaths initially appear as an asthma attack, with no or very mild symptoms for the first 30-90 minutes after the consumption of food containing soy. Then, the children suffer fatal asthma attacks.
What Can I Do to Protect My Child with Peanut Allergy?
According to Dr. Yman, PhD of the Swedish National Food Administration, “If your child is allergic to peanuts, you should consider eliminating soy as well as all peanuts from your child’s diet, even if your child has never reacted poorly to soy in the past. Some sensitive children have “hidden” soy allergies that manifest for the first time with a severe – even fatal – reaction to even the low levels of “hidden” soy commonly found in processed food products. Those at the highest risk suffer from asthma as well as peanut allergy.”
The Swedish National Food Administration study analyzed severe food allergy reactions of children that died after consuming soy. These children had known allergies to peanuts but not to soy.
What products contain soy?
Soy can be found in soy milk, tofu, soy sauce, baby formula and other soy products.
Soy is also used in many processed foods, as soy lecithin, soy lectin, soybean oil and other soy derivatives.
Soy is commonly used as animal-feed in livestock.
It is only within the last nine years that soy has become one of the top eight allergens.
Soy has recently been genetically engineered to contain new proteins and potential allergens.
Are there other facts that I may not know about soy?
According to Daniel Sheehan, PhD and director of the Food and Drug Administration’s (FDA’s) National Center for Toxicological Research, soy-fed babies are taking part in “a large, uncontrolled and basically unmonitored human infant experiment.”
The British Dietetic Association now warns parents to avoid soy formula given the results of a 2003 study conducted by Dr. Gideon Lack from St Mary’s Hospital, Imperial College, London, UK.
The French Food Agency will soon require warning labels on all soy foods, soy formulas and soy milk so that consumers will be aware of the risks that soy poses to children under the age of three, those with hypothyroidism, and women with a family history of breast cancer.
In January 2006, the American Heart Association reversed its position on soy.
Why haven’t I heard this before?
AllergyKids is one of the first independently funded food allergy organizations in the world. We highlight all food allergy research that relates to the health and well-being of children and their families.
Being independently funded, AllergyKids is able to avoid conflicts of interest that funding ties may present – the importance of which is detailed in the work of Dr. Susan Linn of Harvard University and Marion Nestle, former editor of the Surgeon General Letter on Nutrition and Health.
What can I do to learn more?
AllergyKids would like to highlight the work of Kaayla Daniel, PhD. In her book, The Whole Soy Story, Dr. Daniel details the cross reactivity between soy and peanut, specifically addressing in detail the risks that soy poses to children with peanut allergy and asthma.
In the United States, the Weston A. Price Foundation is spearheading efforts to address children with peanut allergy who were fed soy as infants and toddlers.
What else can I do?

As Robert F. Kennedy said, “Some men see things the way they are, and ask ’why?’”
For our children, we see things the way they should be, and ask ’why not?’
In our quest for a cure for these children, no truth is too complex. We must simply have the courage to pursue it.
With hope for our children,

About Robyn O’Brien: Prior to launching AllergyKids, Robyn was in the process of applying for a PhD after drafting her first book, Sugar Mamas: Nutrition’s Impact on the Health and Well-Being of Mothers and Their Children. When her fourth child was diagnosed with potentially life threatening food allergies, she curtailed her personal pursuit in an effort to create greater awareness of the millions of children with food allergies.
Prior to motherhood, Robyn worked as an analyst on one of the nation’s largest mid-cap portfolio management teams. Her team was responsible for $20 billion in assets, covering everything from Enron, to Ebay to Martha Stewart. Robyn received an MBA in finance on a full scholarship and was a Fulbright Fellow.
In her efforts to create awareness of children with food allergies, she has received encouragement from Erin Brockovich and parents around the world.
Robyn asks that you please consider forwarding this email to others who are looking to protect the health and well-being of their families.
I could not get into the conference call, but it is a very educational conversation.
AAAAI: Oral Immunotherapy Dampens But May Not Cure Peanut Allergy

SAN DIEGO — An oral immunotherapy regimen can help take the sting out of severe peanut allergies, reported investigators here.
Five of seven children with severe peanut allergy were able, after two years of immunotherapy, to tolerate a dose of 7.8 grams of peanut flour, equivalent to eating more than 13 peanuts, reported Scott David Nash, M.D., of Duke in Durham, N.C., and colleagues.
Caution patients that oral immunotherapy should not be attempted at home, and should only be performed under the close supervision of a physician because of risk of anaphylaxis.
This study was published as an abstract and presented as a poster and at briefing at a conference. These data and conclusions should be considered to be preliminary as they have not yet been reviewed and published in a peer-reviewed publication.
Yet while oral immunotherapy can desensitize patients to peanuts, children who undergo it may not be in the clear, cautioned the authors in a featured poster session at the annual meeting of the American Academy of Allergy, Asthma & Immunology here.
“We think that our patients are now at decreased risk for anaphylaxis if they have accidental ingestion [of peanuts], but we’re not recommending that our patients reintroduce peanuts into their diets, and all patients were on peanut-elimination diets during the study,” said Dr. Nash.
The investigators enrolled children with a convincing clinical history of peanut allergy who had peanut-specific immunglobulin E (IgE) of 7kU/L or greater.
The children were started on a modified rush immunotherapy protocol, performed in the research unit, in which they would receive over one day increasing multiple doses of peanut flour (mixed in a food of choice, such as applesauce), with dose escalating from 0.1 mg to 25 mg, or, if tolerated, to 50 mg. About half of the patients were able to tolerate the 50 mg dose by the end of the day; the remainder were able to tolerate either 12.5 or 25 mg, said Dr. Nash.
The children then went home and remained on their current dose daily, returning to the center every two weeks for a dose increase until they reached a dose of 300 mg, equivalent to about one peanut. Parents were asked to keep a daily diary of symptoms.
After patients had been maintained on 300 mg of peanut flour daily for two years, they returned to the center for an open food challenge of up to 7.8 g of peanut flour, equal to a good adult-sized handful of nuts. The challenge was delivered as escalating doses beginning at 600 mg every 30 minutes up to the maximum.
In all, five of seven patients had no reaction on the food challenge. One patient took the full dose, but 90 minutes later had a reaction, including stridor, that required epinephrine. The remaining patient made it to 4,200 mg, and then required epinephrine for cough and diffuse hives.
They also looked at immunologic characteristics of food allergy, and found that peanut-specific IgE and IgG both rose initially and the fell during the study, while peanut-specific IgG4 increased throughout the study.
“Peanut oral immunotherapy, we feel, is safe and effective for peanut-allergic patients, and we feel that our immunologic findings for peanut oral immunotherapy are similar to what we find for other forms of oral immunotherapy,” Dr. Nash said.
