Will the phytoestrogens get into the eggs of chicken fed soy?
A. Yes, the phytoestrogens can end up in the yolks–not as high as in commercial eggs, but they will be there. However, eggs are such a good food that we still recommend them. One of our goals is to get farmers away from using soy for their chickens. But this is going to be difficult as the practice is almost universal–even for pastured poultry. We’d like to see chickens given whey, skim milk and bugs as their protein source. But without soy (which contains growth-stimulating estrogens), chickens grow much slower. Consumers must be prepared to pay more for soy-less chicken and eggs.
