As of 2014, plant-based estrogens are thought to be part of a healthy diet, though there is a lot of conflicting data whether a diet rich in soy-based products is healthy, according to the Breast Cancer Fund. While soy is a rich source of phytoestrogens, some research indicates that it causes an increased risk of breast cancer in women.

The similarities of phytoestrogens to the body's naturally produced estrogen on a molecular level allows the plant-based estrogens to both mimic and act as an antagonist to the body's natural estrogen. These substances have been shown to help lower the risk of osteoporosis, breast cancer, heart disease and menopause symptoms, according to the National Institute of Health. However, many phytoestrogens are thought to be endocrine disruptors, meaning that they can cause potentially adverse effects to one's health.
