BPA, or bisphenol A, is a chemical compound commonly used in the production of certain plastics and resins. It is often found in items like water bottles, food containers, and the lining of canned foods. BPA helps make these products durable and resistant to heat. Concerns have been raised about the potential health effects of BPA, particularly its ability to mimic hormones in the body. Some studies suggest that exposure to BPA may be linked to various health issues, prompting many manufacturers to create BPA-free alternatives for consumer safety.
