Yoga of Menopause - Alternatives to Hormone Therapy
weak hormones and hormonal precursors. Phytoestrogens in foods are metabolized by the short path. Phytoestrogens appear to protect tissues from the cancer-causing effects of estradiol, xenoestrogens and pharmaceutical hormones. Phytoestrogens in foods prevent cancer and promote health; phytoestrogen supplements and processed soy fake-foods may do the opposite. Breast cancer occurs four times more often in women whose urinary output of phytoestrogen by-products is low compared to women whose urinary output is high.
Phytoestrogens are common in food. They are concentrated in seeds (grains, beans, nuts, berries) and roots. The exceptions to the rule that plants don't contain human hormones: French beans, rice, apple seeds, licorice, and pomegranate seeds contain the "weak" estrogen estrone.
To get the greatest benefit from phytoestrogenic foods and herbs remember:
1. Isolated phytoestrogens are not as safe as those "in matrix."
2. To make use of plant hormones, you need active, healthy gut flora.
3. Herbs and foods rich in phytoestrogens need to be used in different ways.
4. Phytoestrogens may have different effects on women who do not have their ovaries.
1. Plants contain many types of phytoestrogens; additionally, they contain minerals and other constituents which help our bodies modify the phytoestrogens and so we can use them safely. Red clover is mineral-rich and contains all four of the major types of phytoestrogens: lignans, coumestans, isoflavones, and resorcylic acid lactones. It is the world's best-known anti-cancer herb. In general, foods and herbs rich in phytoestrogens, with the possible exception of licorice, show anti-cancer abilities. Isoflavone, however, when isolated (usually from soy) has the opposite effect: in the lab it encourages the growth of breast cancer cells (endnote 32 in New Menopausal Years).
2. Plant hormones, including most phytoestrogens, can't be used by humans. But we can convert them into ones we can use - with the help of our gut bacteria. When women take antibiotics, their excretion of phytoestrogens plummets. Get your gut flora going by eating more yogurt, miso, unpasteurized sauerkraut, homemade beers and wines, picked-by-your-own-hands-and-unwashed fruits and salads, sourdough bread, and whey-fermented vegetables. (See Nourishing Traditions by Sally Fallon for whey-fermented vegetable recipes.)
3. Plants which are exceptionally rich in phytoestrogens are regarded as powerful herbal medicines. Plants which are good sources of phytoestrogens are regarded as foods. While food can certainly be our medicine - a practice I advocate - it is also true that medicines are more dangerous than foods. Foods rich in phytoestrogens are different than medicinal herbs rich in
