What are phytoestrogens?<\/strong><\/span><\/h3>\n\n\n\n

Phytoestrogens are natural substances that are found in more than 300 plants and are found mainly in their outer layers. Their chemical structure resembles that of polyphenols, and otherwise they resemble the body's own estrogens. <\/span><\/p>\n\n\n

Phytoestrogens have different sub-groups of substances, the two most important being isoflavones and lignans.<\/span><\/p>\n\n\n\n

Isoflavones are mainly found in soybeans and other legumes. Lignans are mainly found in oilseeds such as flaxseed and some cereals. The content of phytoestrogens in plants is quite different and varies further depending on the method of cultivation, processing, climate, time of harvest and storage conditions.<\/span><\/p>\n\n\n\n

How do phytoestrogens work?<\/strong><\/span><\/h2>\n\n\n\n

Phytoestrogens<\/strong> <\/a>have an effect similar to that of the body's own estrogens, but their effectiveness is no more than one thousandth that of estradiol, the most potent endogenous estrogen. <\/span><\/p>\n\n\n

With a diet rich in phytoestrogens, it is possible to consume such high amounts that they can supplement or replace the deficiency of the body's own estrogens.<\/span><\/p>\n\n\n\n

Phytoestrogens have one very useful property: When estrogen is deficient, they exhibit an estrogen-like effect. However, if there are large amounts of estrogens in the body, they can weaken their effect, i.e. may also act as anti-estrogenic.<\/span><\/p>\n\n\n\n

There is evidence that phytoestrogens suppress the growth of glandular tissue cells in the breast (anti-estrogenic effect) but have a positive effect on bone density (estrogen-like effect). There are various epidemiologic and initial clinical studies demonstrating beneficial effects of phytoestrogens on hot flashes and sweats, cardiovascular disease, osteoporosis, and breast cancer.<\/span><\/p>\n\n\n\n
