Chemicals like bisphenol-A (BPA) and phthalates have been getting some airplay recently. These chemicals are used in plastics and other products you may have around the house.
Research has been uncovering some disturbing data about these chemicals for some time. And now, there is something more to worry about.
Turns out that research from the University of Michigan has indicated BPA and phthalates may alter your thyroid hormone levels. This is bad news because thyroid hormones affect so many aspects of your health and well-being.
Thyroid hormone system regulates your body temperature and heart rate. It maintains your digestion, your metabolism, your mood and your ability to reproduce.
BPA is used in some plastic bottles and canned-food linings. Drink the liquid from the bottles, eat the food from the cans, and you are very likely also ingesting some BPA.
Researchers saw that the more exposure to these chemicals, the lower the level of thyroid hormones. This research was reported on July 14, 2011, in an article on MedlinePlus, as well as in a July 11, 2011, Eurekalert! public release.
Ready for some more letters of the alphabet that seem to be up to no good?
According to a January 21, 2010, article on Sciencedaily.com, research from the University of Exeter and the Peninsula Medical School has found a possible connection between perfluorooctanoic acid (PFOA) and thyroid disease.
PFOA is used in non-stick cookware and stain-resistant, water-resistant carpets and fabrics. It has become popular because it's great at repelling grease, heat, stains and water.
It's in clothing that is flame-resistant and waterproof. It's used to coat wire and is found in chemical-resistant tubing. PFOA can also show up when other chemicals break down in fast-food containers.
The presence of PFOA has spread so that PFOA is found in our blood. It is found in animals. It is speculated that we are ingesting PFOA and it is contaminating us through products in our homes.
People in the study with higher levels of PFOA in their blood also had a higher occurrence of thyroid disease.
