A chemical used to in coatings applied to the interior of food and beverage containers and clear plastic bottles has been linked to heart disease, and women are especially at risk. Researchers at the University of Cincinnati have discovered that bisphenol A (BPA) may be responsible for arrhythmias (irregular heartbeats).
BPA is used in several items that we use on a regular basis, including bottle tops and baby bottles. In use for the past 50 years, it is also found in dental fillings and sealants. This material has previously been linked to prostate cancer, breast cancer, and certain neurological defects.
The current study, conducted on mice, showed that BPA acts on the heart in the same way as estrogen does; it changes the concentration of free calcium in the heart muscle and causes it to beat in an irregular manner.
