Child with severe allergy to peanuts and soy. Any way of outgrowing the allergy?

My 6 year-old daughter is allergic to soy. Tests results: 4.62 kUA/L. She is also severely allergic to peanuts (40.80 kUA/L with one severe reaction so far) and 8 other food allergens. We haven't witnessed any symptoms that we could have linked to soy consumption.

- What exactly would you recommend she avoids: food that may contain trace amounts of soy? food that contain soy protein? food that contain soybean oil? What about soy lecithin?
- How important is it that she avoids contact with soy to eventually outgrow her allegy to soy?
- Would daily, moderate exposure to soy increase chances of aggravating her allergy to soy? and her prognostic for outgrowing her allergy to soy?

Many thanks in advance,
Matthieu

Thanks for using Health Care Magic Forum,

Soy Induced Anaphylaxis in Child with Asthma and Peanut Allergy
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?
The child suffer fatal asthma attacks.

What Can I Do to Protect My Child with Peanut Allergy?
"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.”

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.
Daily moderate exposure to soy increase chances of aggravating her allergy .
