Embryologic Whey Protein is the first whey protein in the history of the sports nutrition industry to NOT contain soy lecithin.
Soy oil contains phytosterols and because soy lecithin comes from soy oil, it too contains phytosterols. Therefore soy lecithin exerts estrogenic effects in the human body.
The plant estrogens known as phytosterols; beta-sitosterol, campesterol and stigmasterol have all been found in soy lecithin through independent laboratory analysis. Years ago pharmaceutical companies used these phytosterols to make human sex hormones. And now big whey protein manufacturers use soy lecithin to instantize your whey protein powder. The phytosterols in soy lecithin cause endocrine disruption in the body. The phytosterols are similar to the isoflavones found in soy protein (genistein and daidzein). Even more alarming is the phytosterols found in soy lecithin are structurally similar to the synthetic estrogen diethylstilbestrol (DES). Therefore soy lecithin may increase estrogen and decrease testosterone in your body.
I have estrogen receptor positive breast cancer and cannot have soy products. The phytoestrogens produced from the metabolism of soy stimulates the growth of tumor cells. I looked everywhere for soy free whey because I need more protein in my diet. Every protein product I looked at had soy lecithin in it until I looked online and found this site. I finished my first canister of powdered whey yesterday and loved it! I got the chocolate flavor. I just ordered more and highly recommend this product.
YAAAA! NO SOY! I had about given up on finding a no-soy product.
I love the taste mixed with water; hubby doesn't. I'm using it as weight loss meal replacement and it's working great.
