BPA is bisphenol a. It has been around since the 60s. It is considered to be an industrial chemical. It is used in polycarbonate plastics and epoxy resin production. These plastics are often used to store food and beverages such as water bottles, CDs, and DVDs. It is also used in thermal paper for sales receipts. I am aware of the sales receipts of both McDonald's and Walmart being coated with BPA. You can tell if a receipt has BPA on it by taking something hard such as a coin and scratching it on the paper. If a black type tracing develops then it is BPA coated. Individuals handling these receipts have high estrogen levels. Epoxy resins are used to coat the interior of cans and bottle tops as well as water supply lines. Some dental sealants and composites also contain BPA.
Some research has indicated that BPA can seep into food and/or beverages.
One should avoid plastic containers particularly those that are hardened and clear.
BPA exhibits hormonelike properties. It is referred to as an endocrine disruptor.
BPA's ability to mimic the effects of natural estrogen comes from the similarity of the phenol group on both BPA and estradiol. This enables the synthetic molecule to trigger estrogen pathways in the body. Biphenyl a is and endocrine disruptor. It interferes with the production, secretion, transport, actions and functions and elimination of natural hormones. BPA can imitate the body's own hormones in a way that could be hazardous for health.
Babies and young children are especially sensitive to the effects of BPA.
BPA mimics estrogen in the body and can cause reproductive disorders such as affecting egg maturation, male impotence, with erectile dysfunction as well as problems with memory and learning and normal development.
BPA has also been associated with asthma.
Look at the information encoded on a plastic bottle. If not made from BPA leaching plastic it should be marked BPA free. Look for the words like polycarbonate, Lexan, polysulfone, as these are plastics that often contain BPA.
Bottles marked with 7 are likely containing BPA and those marked with the 1,2,4 or 5 are probably not.
Colored plastics are usually BPA free. Also the plastics that are a bit flexible are usually free of BPA.
My research has led me to believe that the powers that be could have used a substance in the production of plastic that would not have had these estrogen mimicking tendencies. Furthermore the alternative substances actually cost less then BPA. It has been stated that there is hyper feminization of the females and feminization of the males and this seems to be the ultimate goal. Girls are now entering puberty at 8-9 years old as compared to 12-13 in the past. Overall fertility levels have been dropping.
My patients are made aware of the dangers of BPA and if this is the type of physician that you would like to have contact the clinic to make an appointment.
