the soy oil is the worst, you can eat many grams of fish oil, peanut butter, sunflower oil and not get an estrogenic response whereas the same amount of soy oil can cause estrogenic effects like itchy/painful nipples etcJust speculating, but how many of the phytoestrogens are really left in the oil after the refining process? Probably not enough to have a distinct effect. I believe, like you said, that he was referring to the unsaturated fats being the problem. Not that added estrogens are good, but any PUFA is going to have the negative effects, based on Ray's teachings.
