Hormonal

Dietary phytoestrogens (specifically isoflavones from soy and lignans from flax) may confer health benefits for cardiovascular disease, cancer, osteoporosis, and menopausal symptoms through both estrogen-receptor-dependent and independent mechanisms.

Incorporate soy (tofu, tempeh, soy milk) and flaxseed into your diet. While clinical results on cholesterol vary, the mechanistic and epidemiological evidence suggests these foods may support heart health and hormonal balance, especially for postmenopausal women. Note that individual gut bacteria determine how effectively you process these compounds.

ModerateConditionalMEDIUM confidence
Accumulating evidence from molecular and cellular biology experiments, animal studies, and, to a limited extent, human clinical trials suggests that phytoestrogens may potentially confer health benefits related to cardiovascular diseases, cancer, osteoporosis, and menopausal symptoms.

Why this rating

Strong mechanistic and epidemiological data, but human clinical trials show inconsistent results regarding lipid profiles and other outcomes.
