One of these is not like the others: > Phytoestrogens — naturally occurring substances in plants that have hormone-like activity, such as genistein and daidzein that are in soy products, like tofu or soy milk Your comment doesn’t explicitly say that Phytoestrogens are only present in soy, but it should be clear that such compounds are extremely common, even though people tend to single out soy (largely because soy has been the most studied for potentially positive health reasons). Phytoestrogens are present in many different grains, legumes, nuts, seeds, vegetables, etc [0] [0] https://en.wikipedia.org/wiki/Phytoestrogen?wprov=sfti1 https://en.wikipedia.org/wiki/Phytoestrogen?wprov=sfti1
