Endocrine Disruptors
Lesley Glover, MD
There has lately been a lot of discussion and concern about how chemicals in the environment can affect our health. At a continuing education conference recently, we reviewed substances known as endocrine disruptors – chemicals, both natural and man-made, that can interfere with the hormonal system. This discussion served as a reminder of things that many of us know, but also as a learning experience. Here is some background, as well as tips to minimize your exposure to endocrine disruptors.
The endocrine system, also referred to as the hormone system, is found in all mammals, birds, and fish. It is made up of glands located throughout the body; hormones (i.e., chemical messengers) that are made by the glands and released into the bloodstream or the fluid surrounding cells; and receptors in various organs and tissues that recognize and respond to the hormones. The endocrine system regulates all biological processes from the conception of an organism through adulthood and into old age regulating many functions of a body, including metabolism, blood sugar levels, growth and function of the reproductive system, and the development of the brain and nervous system. The female ovaries, male testes, and pituitary, thyroid, and adrenal glands are all endocrine glands.
Some chemicals can interfere with the endocrine system. They are called ‘endocrine disruptors’. . Endocrine disruptors may be found in many everyday products– including plastic bottles (BPA and phthalates), metal food cans, detergents, flame retardants, food (especially soy and beef), toys, cosmetics, lotions (ie tea tree oil and lavender), and pesticides. It is extremely difficult, if not impossible, in this day and age to avoid all endocrine disruptors, but here are some steps we can take in our daily lives that can decrease our exposure:
Try to go organic where possible, with foods. This minimizes exposure to added hormones as well as pesticides. Store foods in glass containers instead of plastic, when feasible. Pay attention when purchasing food or drinks in plastic containers – look for bisphenol-A/phthalate free containers. Also , avoid plastic food and drink containers that are designated as number 3, 6, or 7 (numbers usually located inside a small triangle imprinted in the container). Never heat plastic containers (including baby bottles) in the microwave. Do not wash plastic dishes in the dishwasher.
There is not enough room in any one article to detail all of the different chemicals that are considered endocrine disruptors, but the above suggestions are a good place to start. You can also find more information at the Centers For Disease Control website at cdc.gov/exposurereport.
