Soy Protein Found In Egg Yolks & Chicken Tissue
Do you go out of your way to avoid soy? Do you have soy allergies? Did you ever find yourself allergic to eggs?
You might actually be allergic to the under-the-radar soy found in eggs and chicken, even organic. We are so busy checking ingredients lists that it can be easy to overlook the soy that winds up in the animal and eggs through its feed – heavily soy-based. Commercial chicken and eggs, even organic ones, are better avoided if truly free range non-soy fed chickens can be found.

Soy protein present in egg yolks and chicken tissues
There is a growing market today of consumers trying to avoid soy in their diet. Many people have developed soy allergies, and a number of people are concerned about the plant estrogen properties of soy protein. Soy protein is linked to the rise in hypothyroidism, early puberty in young girls, and lower testosterone levels in men, among other problems. Much of this research is documented in Dr. Kaayla Daniel’s book “The Whole Soy Story.”
What most people do not realize, however, is that due to the predominance of soy in animal feeds, soy protein is probably present in your food even if it is not listed as an ingredient anywhere. Very little testing has been done to determine if the soy protein from the animal feed is passed into the end products we consume. Most laboratories do not even have tests available to test for this.
Professor M. Monica Giusti, a poultry biologist of The Ohio State University, is one of the few people who has done research on soy isoflavones appearing in commercial egg yolks. She has designed lab tests to detect soy isoflavones. In 2009 one of her students published a master’s thesis on the transfer of the soy protein into egg yolks and chicken tissue: Quantification of Soy Isoflavones in Commercial Eggs and Their Transfer from Poultry Feed into Eggs and Tissues. The results of the study as stated in the abstract:
Isoflavones are potent phytoestrogens found in soybeans. Soybean meal constitutes a main ingredient of poultry feed and isoflavones may transfer into eggs and tissues. Our objective was to determine the transfer and accumulation of isoflavones from the feed into hen eggs and tissues, making them isoflavone sources in the human diet. Isoflavone content of commercial eggs with different claims were analyzed by HPLC-MS after hydrolysis. All commercial samples contained soy isoflavones and the metabolite equol. Then, 48 laying hens were fed soy-free, regular (25% soybean meal) or isoflavonerich diet. Isoflavones were found in experimental eggs and tissues. Enhancement of the diet with 500 mg isoflavones/100g feed resulted on egg yolks containing 1000μg isoflavones/100g while livers, kidneys, hearts and muscles contained 7162 μg/100g, 3355 μg/100g , 272 μg/100g and 97 μg/100g , respectively. The results showed that diet can be altered to modulate isoflavone content in hen eggs and tissues.
The author of the study has a pro-soy view of soy protein, so the study was designed to encourage more soy protein to be transferred to egg yolks and poultry tissue. The parameters of the study included comparing chickens fed a soy-free feed, and at the time Tropical Traditions’ soy-free Cocofeed was the only feed available for them to use. Since they started with laying hens that had been raised on a soy-based diet, they conducted periodic tests to determine how long it took the soy-protein to not show up in egg yolks after starting on the soy-free Cocofeed. No trace of the soy isoflavone was found after 10 days following the conversion to the soy-free Cocofeed.
So if you think you are allergic to eggs, it could be that you are actually allergic to soy protein, which is present in virtually all commercial eggs, including organic ones.
Tropical Traditions currently sells its soy-free feed from a feed mill in southwestern Wisconsin, and is currently in the process of having a feed mill on the west coast also have it available. They can be contacted here. In addition to their soy-free eggs, Tropical Traditions sells chickens and turkeys raised on their soy-free Cocofeed from their Grassfed Traditions website.

Soy isoflavones are not protein, so the whole allergy premise is wrong. There could be concern about phytoestrogens, but the amounts are in micrograms, and isoflavones in soy and other products are measured in milligrams. It’s important to be concerned about our food supply, and there is a legitimate debate about soy. But, this article is simply filled with misinformation.
I’m allergic to soy and eggs aren’t ok for me to eat anymore either. Even a trace of soybean oil can make me very very sick.
Even in situations where I’m not supposed to be able to have a reaction to it. Soy has pretty much destroyed any chance at normal life for me since it’s in everything and I’m constantly having to fight my own immune system. I’m so tired of being sick from things I can’t control.
I’ve been allergic to soy for about 5 years now. I have been developing my own research by testing foods that have the smallest traces of soy, but I still react even to the smallest amount. I had also been reacting to eggs for about 2 years now, so I stopped eating them. Later, I saw an advisement for eggs saying, “We feed them soy!” At once, I thought oh my goodness. I hadn’t even thought of it being traced into the eggs and meat. I was able to find local farmers that feed their chicken corn and not soy. I haven’t had a problem with them since. I love your research. I’m so glad there is actually some testes backing it up now, some nutritionists that I have talked to just thought I was crazy, but it is true. If you don’t believe the research, I’m leaving proof. If the chickens are feed soy, it is traced into their eggs!!!
S.M. I don’t know who you are, but I would love to help support you. I felt the same way you do right now. But in the past year, I’ve really been able to take control of this allergy. And now I’m living with somewhat of a normal life. It may not be normal to other people, but I’m strong, health, and I feel more confident now that I can control my life and not this soy-allergy.

Soy is toxic and that is why they are lacing it into everything,… they are decereasing the agenda by poisoning us through the food supply and vaccines. Americans better wake up to all this before they are dead! Its a shame people are so dumb!
Some eggs are worse than others. I am guessing it is the percentage of soy in the feed and the type of chicken and other demographics in the flock. Soy makes me feel like garbage so I know if I have eaten anything with it..even if it is not listed. Eggs and chicken are the main offenders. They are soying us to death to make us sick, tired, and sterile.
Dear Peggy
“But,this article is simply filled with misinformation.”
How I wish you were correct. IMO it is right on.
You are correct soy isoflavones are not protein. BUT they act as hormones in the human body and hormones are weighed in units below the nanogram.
The problem with flooding your body with xenohormones is the foreign hormones send signals throughout your body; signals that act as random noise or worse. These signals may cause a cell to abort an action in progress or initiate a harmful action. IMO they may possibly initiate cell destruction. Xenohormones threaten our very existence as a Species. Which is why they are in our “food supply”. Depopulation politics reigns supreme. Each generation more young couples have trouble conceiving a child and often must pay many tens of thousands of dollars for what 200 years ago took a simple roll in the hay to accomplish. In a generation or two no amount of money will enable them to conceive, just as planned and engineered. Please wake up we are being systemically exterminated. You can bet your bottom dollar the Rothschilds and Rockefellers do not eat this crap.
Soy isoflavones may have a pharmaceutical use just as the dearly SSRIs have a pharmaceutical use. But no one cognizant of health will use them.

Fortunately I don’t seem to have any soy allergy, but I do have allergies. I know it is not ning to be a protein necesary for something to cause allergies. I never once gave any thought to soy being in eggs though. But whatever is in the air here in Oregon is bad enough I have noticed in the last 6 months or so. That my nose is constantly stuffy and crusty and every single day I wake up with what looks like salt water evaporation pools around my eyes, that need copious water to remove. Watch out people they seem to have stepped up whatever they are doing. In my opinion I think we need to stop supplimenting animal feed with grains and get back to what they would be eating if they were not being kept by humans. All grass feed beef and chickens that are outside pecking at the ground like nature intended, they also get protein from feeding that way, you don’t think grass is sterile and bug free do you?
