Since those who have PCOS have high testosterone levels, it would make deductive sense that increasing phytoestrogen consumption would help to mitigate symptoms—and many studies support that theory. It’s important to note, though, that soy is often genetically modified and processed, which can further perpetuate hormone imbalances by potentially triggering an overload of estrogen—which comes with its own set of symptoms.
These plant-based estrogens are not produced by your endocrine system. They’re gained through eating phytoestrogen-classified plants. Soy is the most controversial phytoestrogen and is common in a lot of gluten- and plant-based products due to its high protein content. However, all legumes (think: lentils, flaxseeds, and sesame seeds) are considered phytoestrogens.
