This is proven; while soy still has no evidence against it (even GM soy) – only speculation. Soy lecithin is found in a lot of modern processed foods. To make soy lecithin, soybean oil is extracted from the raw soybeans using a chemical solvent (usually hexane). [2] This supports the idea that soy lecithin could have similar estrogenic effects as other soy foods. gh – why do you say that lecithin has estrogenic activity? I can’t speak on behalf of highly processed “foods” (tofu is not one of them; it’s just curd) but there are 5th generation Vegans (and older) that are healthier than the rest of the US population. They concluded that “a so-far unidentified estrogen-like compound” is present in soy lecithin that accounts for its estrogenic activity. I know there very knowledgeable ladies here about this so I thought I'd ask here. This is thought to be because the isoflavones in soy can act like estrogen in the body, and increased estrogen has been linked to certain types of breast cancer. (9).
