BPA in Canned Food: Health hazards of BPA
Bisphenol A has been shown to mimic thyroid and sex hormones in people and animals. It has been associated with a wide variety of health problems, including altered brain and nervous system development and changes in the reproductive system. Much of the evidence of BPA toxicity is based on laboratory animal studies, where low exposures to BPA during pregnancy or early life can permanently affect fertility, behavior and body size and can predispose animals to later life cancers (Vandenberg 2013).
There is less than definitive evidence of BPA toxicity to people, but observational studies associate BPA exposure with a host of issues, including behavioral changes in children and diseases like obesity and heart disease.
While it is not clear how much BPA ingestion is harmful to humans, the existing evidence suggests that the developing fetus and young child are most at risk. Children cannot metabolize and excrete BPA as quickly and efficiently as adults (Edginton 2009, Ginsberg 2009). Detoxified BPA can be reactivated as it passes through the placenta to the fetus (Corbel 2015).
