This is a nice overview on the dangers of BPA. Among the risks: “According to Environmental Defence, even low-level exposure to BPA, or 4,4’-(propane-2,2-diyl)diphenol, is linked to infertility, heart disease, miscarriage, behavioural problems, and predisposition to breast and prostate cancer”. It has also been linked to childhood obesity. A common exposure to BPA is via the lining used in canned goods. Please limit canned foods to those which are either in glass or are labelled BPA-free.
