Polycarbonate drink containers are also a source of exposure, although most disposable drinks bottles are actually made of PET, which contains no BPA.
Polycarbonate is commonly used in eye protection, as well as in other projectile-resistant viewing and lighting applications that would normally indicate the use of glass, but require much higher impact-resistance. Polycarbonate lenses also protect the eye from UV light.
The study's findings include: 1) evidence of BPA in participants' urine decreased by 50% to 70% during the period of eating fresh foods; and 2) participants' reports of their food practices suggested that consumption of canned foods and beverages and restaurant meals were the most likely sources of exposure to BPA in their usual diets.
These physical changes can be considered when assessing why an older person might not be getting the nutrition they need. As taste buds change with age, certain foods might not be seen as appetizing.

A precursor to the Oreo Mega Stuf, the Big Stuf consisted of one giant Oreo the size of your palm, which stuck around for seven years until it was discontinued in 1991. Reddit 24.
A polycarbonate is an oxocarbon dianion consisting of a chain of carbonate units, where successive carbonyl groups are directly linked to each other by shared additional oxygen atoms. That is, they are the conjugate bases of polycarbonic acids , the conceptual anhydrides of carbonic acid , or polymers of carbon dioxide .
