While industry is working to replace BPA because of health concerns it may be going in the wrong direction. Plasticizers with estrogenic activity, such as bisphenol A (BPA), have been reported to have potential adverse health effects in humans. Due to mounting evidence of these health effects and public pressure, BPA is being phased out by the plastics manufacturing industry and replaced by other bisphenol variants in ‘BPA-free’ products. This study investigated the estrogenic activity of 6 bisphenol analogues (bisphenol S, BPS; bisphenol F, BPF; bisphenol AP, BPAP; bisphenol AF, BPAF; bisphenol Z, BPZ; bisphenol B, BPB) and found that all six of the substitutions mimicked estrogen. Three of the substitutes—bisphenol AF (BPAF), bisphenol B (BPB), and bisphenol Z (BPZ)—were more potent than BPA at mimicking estrogen in the cancer cells.
The activation of estrogen receptors is behind two thirds of breast cancer cases and all six of the chemicals in the study have been detected in breast milk and urine.
The message here is try to avoid plastics as much as possible. Especially for food storage.
