	Menopause and Phytoestrogens - An Exciting Alternative
		Phytoestrogens are a group of compounds found in plants that influence our own estrogen activity.
		When the phytoestrogens are successful, they decrease overall estrogenic activity because their effect on the target tissues is less than if estradiol had been allowed to bind.
		Much of the early research on phytoestrogens was done with animals and interest was likely sparked by the observation that sheep that grazed too much on clover became temporarily infertile.

	Phytoestrogens : by Ray Sahelian, M.D., phytoestrogens menopause phytoestrogens research
		Phytoestrogens are non-steroidal plant molecules whose structure differs from gonadal hormones, but with an estrogen-type activity: they are capable of interacting with estrogen receptors, showing both agonist and antagonist methods of action.
		The beneficial effects of various classes of phytoestrogens present in nature are now known, but the main isoflavone present in soy, genistein, appears to be particularly effective.
		Although phytoestrogens have not yet been used in long-term trials to evaluate their ability to reduce the risk of prostate cancer, the evidence thus far suggests that they have a protective effect against the growth of prostate tumors.

	Phytoestrogens and Breast Cancer
		Phytoestrogens - acting differently from estrogen - may affect communication pathways between cells, prevent the formation of blood vessels to tumors or alter processes involved in the processing of DNA for cell multiplication.
		Phytoestrogen levels in urine are an accurate measure of phytoestrogens in the body, but it is uncertain how levels in the women with cancer compare to levels in these women during the decades when cancer was developing.
		Phytoestrogens are actively being researched for beneficial effects on cardiovascular and bone health.

	e.hormone \| Phytoestrogens
		In fact, phytoestrogens have one of several fates after being eaten: they can be excreted; they can be absorbed into our bodies; or they can be broken down into other compounds that can also be potent phytoestrogens.
		Evaluating health effects of phytoestrogens is difficult and depends on numerous factors, including the kind and dose (amount) of phytoestrogens eaten and the age, gender, and health of the person.
		Phytoestrogens may help reduce that risk because they may lower a person's lifetime exposure to natural estrogens by competing for estrogen receptor sites or changing the way natural estrogens are broken down.

	Phytoestrogens
		Phytoestrogens, also known as phytosterols or phytochemicals, are natural plant compounds which have a similarity to human estrogens.
		The benefits of phytoestrogens to good health are mainly due to the effects they have on the body's hormonal balance, acting as both agonists and antagonists.
		Phytoestrogens are also thought to act as estrogen antagonists by occupying estrogen receptor sites ahead of the body's natural estrogens and equally importantly ahead of synthetic estrogens and also environmental estrogens derived from chemical products, otherwise known as bad estrogens or xenoestrogens.

		The evidence to support the industry claim is scant and recent work indicates that phytoestrogens may actually increase the risk of breast cancer.

		By exposing your baby to such large amounts of phytoestrogens you are risking permanent endocrine system damage to your child.

	Phytoestrogens
		From analyses of levels of isoflavones (soya phytoestrogens) in soya-based infant formulas available in New Zealand, the researchers calculated that the biological effects of phytoestrogens typically consumed by a baby drinking soya milk would be 100 times greater than the amount of natural oestrogen the child would receive from breast milk.
		Growing evidence indicates phytoestrogens may reduce the risk of certain cancers, especially those which are hormone dependent such as breast and prostate.
		However, evidence also indicates that their action in the human body is complex, and that exposure to endogenous oestrogens, including phytoestrogens in the womb and during early childhood, may pose risks to sexual development.
