There are things in our personal care products, enviroment, food and water called endocrine disruptors. They are chemicals that may interfere with the body’s hormone system and produce negative reproductive, neurological, and immune effects in us and in wildlife. These substances are natural and also man-made they are thought to cause hormone disruption, including pharmaceuticals, dioxins and dioxin-like compounds, polychlorinated biphenyls, DDT and other pesticides, and plasticizers such as bisphenol A. Endocrine disruptors may be found things we use everyday– including plastic bottles, metal food cans, detergents, flame retardants, food, toys, cosmetics, and pesticides. The NIEHS supports studies to determine whether exposure to endocrine disruptors may result in human health effects including lowered fertility and an increased incidence of endometriosis and some cancers. Research shows that endocrine disruptors may pose the greatest risk during prenatal and early postnatal development when organ and neural systems are forming. They also make you fat, cause hair loss, make your PMT worse and.....they cause man boobs. Avoid.
