Isoflavones are phytonutrients found in lentils, soy and other legumes. The chemical structure of isoflavones is very similar to that of our own estrogen and sometimes is referred to as “phytoestrogens” ie plant estrogens.
Studies have shown isoflavones ability to slow prostate cancer growth and caused prostate cancer cells to die. Population-based studies also show a strong link between consumption of isoflavones and a reduced risk of breast and endometrial cancer.
Soy isoflavones appear to reduce cardiovascular disease risk by inhibiting the growth of cells that form artery clogging plaque. Isoflavones also help in the preservation of the bone substance and fight osteoporosis.
Legumes, particularly soybeans, are the richest sources of isoflavones in the human diet.
