The Soy-ling of America: Second-Hand Soy from Animal Feeds

This article appeared in Wise Traditions in Food, Farming and the Healing Arts, the quarterly journal of the Weston A. Price Foundation, Summer 2012.

...People who are allergic to soy may also react to eggs, dairy and flesh foods. This is usually chalked up to multiple allergies, but the cause might well be soy residues from the soy-based chows fed to poultry, cows, sheep and fish. (article)

"This represents a clear and present danger for individuals with soy allergies, and for anyone who wants to avoid over-estrogenization (such as growing boys and women prone to breast cancer)."

Study: Transfer of Soy Isoflavone into the Egg Yolk of Chickens

"A diet containing a high concentration of soy isoflavone was administered to laying hens and the contents of the isoflavones transferred to the plasma and egg yolk were measured."

"A method for quantitatively measuing the concentration of isoflavone in the yolk was first established, before a high concentration of..." (full study).

"These findings clearly demonstrate that soy isoflavone was transferred into the yolk from the feed..."

Study: Biotransformation of soy isoflavone-glycosides in laying hens

..."Here we report that in laying hens daidzin, a soy isoflavone-glycoside, in the diet was transformed into equol, absorbed, transported in circulating peripheral blood, and preferentially accumulated into egg yolkin its conjugated form."

"...These results raise the possibility that feeding domestic animals soy-based fodder produces animal-based foods rich in a more active form of phytoestrogens."

Study: Effects of Dose and Glycosylation on the Transfer of Genistein into the Eggs of the Japanese Quail

"Soy isoflavones have been associated with several beneficial effects of soy in human diets. However, most soy is consumed by livestock in the Western countries."

"... The higher dose of genistein (phytoestrogen) supplementation resulted in higher genistein concentrations in egg yolks. Glycosylation decreased the transfer and accumulation of genistein into the egg yolks." (full study).

"It is possible that isoflavones could be transferred and/or accumulated into animal products, which could become additional sources of dietary isoflavones for humans."

Study. Department of Nutrition and Food Science, University of Maryland


"...Forty-eight laying hens were fed three types of chicken feed: a soy-free feed, a regular feed containing 25 percent soybean meal or a special feed that packed 500 mg soy isoflavones per 100 grams."

..."Not surprisingly, all brands of commercial or organic eggs, whether free range or caged, contained soy isoflavones, with the total isoflavone content per egg ranging from 33μg to 139μg per 100g of egg yolk." (full study).

"The results showed that diet can be altered to modulate isoflavone content in hen eggs and tissues."

Book: The Whole Soy Story: The Dark Side of America's Favorite Health Food

A groundbreaking expose that tells the truth about soy that scientists know but that the soy industry has tried to suppress. Soy is not a health food, does not prevent disease and has not even been proven safe. Epidemiological, clinical and laboratory studies link soy to malnutrition, digestive problems, thyroid dysfunction, cognitive decline, reproductive disorders, even heart disease and cancer.
