Part of it is definitely plastics. Specifically plasticizing agents such as BPA that mimic estrogen, though BPA is far from the only one. The plasticizers that have been used to replace BPA have not been well studied, and they are similar molecules. There is no evidence they are more safe. Ever eat or drink something hot out of a plastic container? Ever touch thermal paper such as a receipt? You just received a dose of synthetic estrogen. Hopefully there will come a time when greater society decides to care about this and limits plastics in food manufacturing and storage.
