Do soy allergens end up in eggs of chickens that eat soy-based feed? For that matter, what about wheat gluten?
The Tropical Traditions site says this:
"Almost all commercial eggs, including those that are organic or marketed as 'Omega 3' eggs, are from chickens fed high concentrations of soy beans. Many people are consuming soy protein in their eggs without probably realizing it. Tropical Traditions’ soy-free organic eggs have been tested to be soy-free."
I have been trying to find evidence of this research. As an extremely soy and wheat-sensitive celiac, I am somewhat skeptical. I eat a lot of eggs and can't trace any allergic reactions to eggs; however, I do get an outbreak of a very persistent rash from time to time and I cannot identify the source. My eating is 100% clean (I prepare all my own meals...I use NO grains, NO processed food, and most adamantly NO soy and or gluten)--unless I'm ingesting something well hidden.
I have long rationalized eating (potentially) eggs from soy-fed chickens on the grounds that the soy proteins are destroyed by the chicken during its metabolism of the feed.
Solving this rash problem is my #1 most difficult and enduring health challenge. As I've learned to identify hidden allergens, I've brought the incidence of rash down to once every couple months. It is the same rash I had when I used to get exposed to soy and wheat on a regular basis, after adopting a soy and wheat-free diet (i.e., when restaurant servers mischaracterized the food they served me, or when I ate something without studying up on it or reading the label).
For what it's worth, I buy both "cage free" and "pastured" eggs from my local co-op. They're all from local chickens but I buy a variety of different brands from many different farms. I have not investigated what each farm feeds their birds but I avoid any egg that says "100% vegetarian diet" (for obvious reasons...chickens aren't vegetarians).
If one (or more) of my sources is periodically giving me a dose of soy proteins, this could explain the rash.
Thoughts? References to research that shows allergen proteins ending up in the eggs (or even flesh) of any animal that ingests said proteins?
