What’s the deal with BPA free?

Bisphenol A has to be one of the most infamous and controversial chemicals. We are all slammed with media telling us not to use products containing BPA. “HC’s (Health Canada’s) study of BPA levels in canned drinks, for example, notes that a person would have to consume 940 canned drinks in one day to reach the tolerable daily intake[of BPA]” – Tolerable daily intake is the amount that a person can safely consume every day in their lifetime. If you drank 940 cans of soda a day do you think it’s the BPA that’ll kill you?

In “More Junk Science? The Anti-BPA Crusade Is BackRonald L. Doering provides an interesting discussion on the safety of BPA, the merits of BPA critics, and additional issues, such as the substantial amount of money that has been spent on BPA research. It’s a short and interesting read! Note that he did not include the references he mentioned, so I will provide most of them here.
