What are bisphenols?

Bisphenol A (BPA) is a chemical compound used in manufacturing various plastics and resins. It's commonly found in products like plastic containers, water bottles, and the linings of food cans. While BPA is well-known, there are other bisphenols, such as BPF and BPS, which are used as substitutes but are not very different chemically. These substitutes often escape regulatory scrutiny and labeling because products may only state "BPA-free," not mentioning the presence of BPF or BPS, which may be just as harmful 1.
