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?

Ive seen anecdotal studies all over about this from individuals with a soy allergy.
Fresh meat??? When an animal is fed a soy-based diet, does the soy ???come through??? in the meat? How about eggs and soy-fed hens? I have never seen research on this subject. I have, however, had one of the worst allergic reactions of my life after eating a small amount of chicken (and nothing else) from a certain famous company. A call to this company revealed that the diet fed to these chickens was entirely soybeans. It is a given that most food animals are fed a diet high in soy??? we discovered firsthand how difficult it is to find soy-free commercial animal feed when we first started feeding our pig, goat, chickens, ducks, and geese. (For the record, these animals were all pets and not for food.) Not everyone will want to do as we have done??? we have almost entirely eliminated meat from our diet, and we have done this for a variety of reasons besides soy??? but if you???re still having reactions and can???t trace the cause, meat from soy-fed animals could be the hidden culprit. Also, with the holidays coming up, you will want to avoid self-basting turkeys or any turkeys that have an ingredient list with ???natural flavors added.???
For highly allergic people, the new labeling law is not enough. Soy oil, lecithin and vitamin E (often added as a preservative) do not fall under the labeling requirement. (The FDA reasons that such products are free of soy protein, which is only true when they are manufactured under perfect conditions.) Animal products too may unexpectedly contain "hidden" soy. Some will appear on labels such as "extenders" added to ground meat, "plasticizers" used to hold patties, meat balls and hot dogs together or soy oil pumped into pre-basted turkeys. But labeling won't help the increasing numbers of people who are starting to react to the flesh of fish, poultry, lamb or cattle that were fattened on soy feed and to eggs laid by soy fed chickens.
Edit: extremely disappointed to find that the Christopher eggs are actually not soy free.
Found another option:

I think they are broken down into their various amino acids and then reconstituted as "egg protein" or "chicken protein." What would transfer over would be the high omega-6 in the feed.

I've had a bout of egg-reaction this week that I'll never forget! Almost sent me to the emergency room. The only trace back was from farm eggs that I bought at a local farmer's market this past week.
I'll certainly be asking some questions next time I'm down there...

I used to get very sick from eating eggs--like food poisoning, about 20 minutes after eating. I went to the doctor and had an allergy test, but negative for eggs. The doctor said that the reaction could be caused by the feed the chickens were eating. Now I only eat eggs from my daughter's chickens, who are fed corn. I don't have any problems with them.

This is effectively what I was trying to ask (in part) in my recent post here
But just worded much better. Thanks for asking this Wjones, I'm looking forward to answers.

Hi Everyone!! Most people who have reactions from eating eggs, are having a reaction to the grain they are fed. It isn't so much the kind of grain soy, wheat, rye but how it is grown, whay it is sprayed with, the biggest problem is the use of roundup. Most hens are fed low quality feed that are made with poor quality grain then preserved with chemicals so the feed doesn't mold and spoil before it is used months later. You should buy eggs from a local farm, where you can speak with the farmer, ask questions like what type of diet do you feed plant based, is your feed laced with chemicals to extend its life? If you have trouble finding a farm close to you, there's farm in Williamstown FAR Wind Farm 1844 Winslow Road 609-774-0629they have a facebook page and a website where you can check them out

If you are affected by soy and gluten because of an autoimmune thyroid disorder, as I am, you may not get a violent reaction when eating eggs that contain those ingredients, but you can still have harm done to your body that you might not detect, like on an immune level. Not everything happening to the body because of soy and gluten is going to show up in an obvious way. But it can still be bad for you. I think we need to eat animals that are raised the way the animals were created to eat. There will always be less problems when we do.

Yeah, unfortunately it's true. Just one "soy-fed-egg" and I'll look like I've spent the night on an anthill.
