plant compounds that have estrogen-like effects. They are being studied as a treatment for osteoporosis.
So-called "plant" estrogens that are produced in the intestines from certain flavonoids, isoflavones (most notably genistein, biochanin A and daidzein) and lignans. Often scientists simply say foods "contain" isoflavones as a kind of shorthand. Phytoestrogens are 250 to 1,000 times weaker than human estrogen but still impact the body. They are suspected of blocking estrogens by tying up estrogen receptors on cells, thus affecting hormone-related cancers, including breast and prostate cancer. They also may decrease hot flashes and other symptoms of menopause, although most of the evidence is anecdotal so far. One scientist likens phytoestrogens to a key that can fit a lock but not open it, effectively blocking the real key. Some phytoestrogens are similar to tamoxifen, a drug used to treat some breast cancers. Soyfoods are rich sources. In one study, tofu was found to contain the most isoflavones of the foods tested, though amount varied by brand (53).
Chemicals found in plant foods that can act like estrogen in the body.
Botanical substances with a gentle estrogen effect
Estrogen-like substances from a plant. Sources include soy, herbs such as black cohosh, a member of the buttercup family, wild yam, dong quai, and valerian root
plant compounds that exert oestrogen-like effects
Estrogen like compounds present in soy and other plants that may help treat symptoms of menopause, certain cancers, and other complaints.
Plant derived oestrogen-like substances which may help with menopausal symptoms.
Estrogenic molecules from plants - especially powerful phytoestrogens come from red clover, soybeans, and hops. See Lancet report on extraordinarily high phytoestrogen levels in the Japanese diet.
Present in soy, black cohosh, and flaxseeds. Phytoestrogens may have a similar effect to estrogens. This may cause growth of liver cysts by triggering the hormone receptors within liver cyst cells. Almost all of us with liver cysts have commented upon that soy and flaxseed causes liver cysts to grow.
chemicals with oestrogenic activity produced in the gastrointestinal tract by the metabolism of complex polysaccharides
phytochemicals from plants such as soybeans that have weak estrogenic actions.
Plant compounds with estrogen-like activity. They are usually considerably weaker than one's own estrogens and compete for the same estrogen receptor sites throughout the body. They have often been used to decrease symptoms of estrogen excess.
Parts of plants that are chemically similar to the hormone oestrogen
Plant compounds that can mimic the human hormone estrogen.
Hormone-like compounds found in plant foods, especially soybeans.
which are plant based compounds that act like estrogen in the body and are found in many foods we eat. ‘Many different plants produce compounds that may mimic or interact with estrogen hormones. At least 20 compounds have been identified in at least 300 plants from more than 16 different plant families. Referred to as phytoestrogens, these compounds are weaker than natural estrogens and are found in herbs and seasonings (garlic, parsley), grains (soybeans, wheat, rice), vegetables (beans, carrots, potatoes), fruits (dates, pomegranates, cherries, apples) and drink (coffee). Phytoestrogens differ a great deal from synthetic environmental estrogens (Xenoestrogens) in that they are easily broken down, are not stored in tissue and spend very little time in the body.
Plant compounds with estrogen-like activity, but weaker than natural estrogen in the body.
Phytoestrogens are plant estrogens. Some studies have shown that they may play a role in conditions such as cancer.
estrogen-like substances derived from plants
Phytochemicals structurally similar to mammalian hormones, such as the female sex hormone estrogen. Phytoestrogens weakly mimic hormone activity in the human body.
A type of phytochemical with some influence on the estrogenic activity or hormonal system in humans. This rather broad term does not mean that the plant mimics human estrogen, only acts to affect it in some way. ()
Estrogen-like substances from certain plants that work like a weak form of estrogen.
Phytoestrogens are phenolic compounds that are natural components of certain plant foods and are structurally similar to mammalian estrogens. Current scientific wisdom says that the actions and effects of phytoestrogens are not thoroughly understood and that an increased (excessive) intake may have adverse effects depending on the age of the person taking them. Studies have shown it to inhibit human estrogen, and thus be a factor in reducing illnesses like breast cancer. Foods high in phytoestrogen have been noted to have positive effects on cancers, though whether that is the phytoestrogens specifically or other factors is unclear. Fermented soy products such as soy milk is high in genistein in particular. find all NHC pages containing: phytoestrogens
Weak, estrogen-like substances found in plants, especially soy. Because of their high phytoestrogen content, there is increasing interest in the role that soy foods can play in women's health. Phytoestrogens are associated with a lowered risk of many diseases, including heart disease, osteoporosis, and breast cancer.
Phytoestrogens are chemicals produced by plants that act like estrogens in animal cells and bodies. They are often trace substances in food. These chemicals mimic and supplement the action of the body's own hormones, estrogen (the British spelling is 'oestrogen').
