Xenoestrogens. What Are They And What Do They Do?
Xenoestrogens are compounds like here http://www.zeroxeno.com that imitate the effects of natural estrogen even though different in structure and chemical composition. They are a sub-category of endocrine disrupters with the ability to bind to the same receptors as natural estrogen and blocking their effects. Estrogen as a natural hormone is regulated through complex bio-chemical pathways and is essential for the growth of bones, clotting of blood and reproduction in both men and women. The endocrine system is meant to release hormones that direct different tissues on what to do.
However, in the presence of the xenoestrogens, the hormone receptors are blocked and this can be critical to sensitive body organs such as the uterus, neurological and immune systems. Xenoestrogens tend to increase the amounts of estrogen present in the body resulting to a situation described as estrogen dominance. This endocrine disrupter is not biodegradable and usually gets stored in the fat cells. The outcome of such a situation is seen through hormonal imbalances and conditions such as infertility, obesity, prostate and testicular cancer, early onset puberty and miscarriages. Sources of xenoestrogens Xenoestrogens are almost everywhere around us.
They are found in:
- Cosmetics, deodorants and hair products which are preserved using parabens.
- Pesticides and agricultural chemicals also contain estrogen like activity which is introduced into the body through ingestion.
- Plastic containers used to food and other household items which contain Bisphenol (BPA). BPA is also found in perfume fragrances in the form of phthalates which is a xenoestrogen.
- Combustion activities, chlorine bleaching of wood pulp and pesticide manufacturing also produce the toxic substances that are released into water masses and land, reaching humans through animals which are the primary consumers.
- Insecticides and aerosols used in homes contain traces of the endocrine disrupter.
- Livestock growth promoters such as zeranol. – Plastics used in making computer monitors, textiles and televisions that contain polybrominated biphenyls (PBB). These plastics do not easily degrade in end up in soil, air and water compositions.
