Bisphenol A or BPA is described as organic synthetic chemical compound, colorless solid and commonly found in hard plastics, resins, baby bottles, water bottles, medical devices, CDs, DVDs and other normal household items. As it is present in numerous products, they are becoming first medium to get exposure to BPA.
Through this enormous exposure to BPA, indirectly we are making it interferes with the production, secretion, transport, action, function and elimination of natural hormones. There is no exception for range of exposure in both babies and adults, all are equally affected.
BPA exhibits hormone-like properties that raise concern about its suitability in some consumer products and food containers. It works by imitating the natural hormone 17B-estradiol. BPA has been shown to alter glucose and lipid metabolism in animal studies. So the FDA authority has ended its authorization of the use of BPA in baby bottles and infant formula packaging, based on market abandonment, not safety.
Bisphenol A was first synthesized by the eminent Russian chemist A.P. Dianin in 1891.Later in 1980’s its industrial production started with amount of 1 million tons.
BPA can be produced by condensation of acetone compound with two equivalents of phenol and this reaction is catalyzed by the hydrochloric acid (HCl) or sulfonated polystyrene resin.
How to avoid exposure to BPA?
- As polycarbonate containers are rich in BPA content, avoid keeping them in microwave. The reason behind keeping them in microwave is, the high temperature in microwave may cause brake down of plastics and causes leaching of BPA into the foods.
- Avoid plastic items which are marked with the Resin Identification Code 7 because these may be made with BPA.
- Reduce the use of canned foods
- Follow precautionary steps while handling and manufacturing products which contain BPA, as inhalation and dermal exposures are the most probable routes.
- Use BPA free baby bottles.
