Phytoestrogens = “plant” estrogens.
These compounds attract quite a bit of controversy, almost as much as the lectins, oxalates, phytates, and goitrogens we’ve talked about previously.

First things first. The term “phytoestrogen” is actually a bit of a misnomer. These compounds are actually not “estrogens” but more accurately “estrogen receptor modulators.” This means they can bind to estrogen receptors to elicit a number of different effects.
There are a number of different plant compounds that are classified as “phytoestrogens.” Far and away the most potent of them are the isoflavones like genestein found in soy. Other compounds include lignans, a type of polyphenol highest in flax, stilbenes like resveratrol found in grapes, and coumestans like coumestrol found in Brussel sprouts, spinach, all legumes, and many other foods.
These fancy-named compounds are all, in a word, “phytonutrients.” When we eat these compounds present in our plant foods our bodies, with the help of the microbes in our gut, respond in all sorts of ways. In today’s episode, we do our best to cover the latest science as it relates to the “plant estrogen” compounds in both male and female bodies.
Spoiler alert - phytoestrogen consumption does not cause female reproductive cancer, nor does it cause men to grow “man boobs!”
