Does Soy Raise Estrogen Levels?

Soy: Healthy or Dangerous?

Lecithins are oily substances that occur naturally in plants (soybeans) and animals (egg yolks).
soy lecithin is made from soy oil, which is usually made through a chemical process using hexane.
Soy lecithin is an additive found in many everyday foods, but it’s normally used in such small amounts that it rarely exceeds more than 1 percent of the weight of any food product. It works as an emulsifier in candy bars, keeping the cocoa and cocoa butter from separating. Soy lecithin also can be used in baking to make the dough less sticky and help it rise. It works as a so-called wetting agent, too, making cake mixes easier to spread into a pan when liquid is added.

But what exactly is it? Well, it’s a substance that is extracted from soybeans using a solvent such as hexane, and it’s a by-product of soybean oil.
In 2007, the GMO Compass reported that soy lecithin, like many food products in American supermarkets, contained genetically modified soy.
A compound of soy lecithin, phytoestrogen, can produce effects on the body similar to the hormone estrogen.
Soy and soy lecithin contain a compound called fenistein that may have a negative effect on fertility and reproduction. According to a study at Johns Hopkins Medical Institutions, rats that were fed soybeans containing genistein produced offspring with abnormal reproductive organs, including smaller testes, larger prostate glands and lower testosterone levels.
Soy lecithin may affect immature brain cells leading to impeded brain development. “Developmental Psychobiology” published the results of a study on brain function in rats fed soy lecithin.
lecithin and other dietary supplements do not need FDA approval,

The concern with soy and cancer comes from the fact that soy contains isoflavones, which are phytoestrogens that in some ways mimic the action of estrogen. However, these phytoestrogens are many times weaker than the estrogen made in human bodies. According to the American Institute for Cancer Research and American Cancer Society, research has shown that moderate consumption of whole soy foods appears safe for both breast cancer survivors and the general public. Moderate consumption of whole soy foods, or 1-2 servings per day, does not increase cancer risk, and may actually lower the risk of cancers of the breast, prostate, and other cancers. One serving is one cup of soy milk, a half cup of cooked edamame or soy beans, or one ounce of soy nuts.
