Villains among EWG’s BPA-free “Best Players”

blog bpa free just released a list of manufacturers who continue to use BPA (bisphenol A) in their products along with a list of the “Best Players” who no longer do. However, there is a big problem lurking with those on their “Best Players” list: Most manufacturers NOT using BPA are instead using its endocrine-disrupting relatives BPS (bisphenol S) and BPF (bisphenol F).

A recent comparison of BPA, BPS and BPF found NO evidence that these bisphenols are safer than BPA and in fact may “have added disruptive effects that have not been detected with BPA.” This means that those “Best Players” may not be good at all!!!

Today, BPS is used in thermal paper products marketed as “BPA- free paper” — your cash register receipts thus continue to provide significant exposure to bisphenols.

BPF is found in BPA-free water pipes, dental sealants, and food packaging.

Both BPS and BPF are in BPA-free personal care products (hair care, make up, lotions, toothpastes), paper products (currency, boarding passes, tickets), and food (dairy products, meats, canned foods, and cereals). BPS and BPF are present in about the same concentrations as BPA in humans, with BPS found in 78% and BPF in 55% of those tested.

BPA is a xenoestrogen, an endocrine disruptor with some 100 human studies showing its negative impacts on our reproductive health, the brain development of our children, our thyroid function, and our metabolic health. BPS and BPF have not been in use long enough to have many human studies showing health issues — yet. But the early studies definitely spell trouble ahead:

BPS killed Daphnia (a food source for many fish), it has acute toxicity. It is estrogenic in rats. In zebra fish, it changed estrogen and testosterone levels, disrupted reproduction, and increased malformations in baby fish and had negative effects on the development of their nervous systems. Some but not all studies showed BPS to be stronger than the strongest human estrogen. There are signs that BPS can damage our liver cells and our DNA.

BPF disrupts estrogen, testosterone, and thyroid function. It is too is acutely toxic to Daphnia. It has a xenoestrogenic effect in rats and altered thyroid hormone levels.

There are signs that BPF may be a stronger estrogen disruptor than BPA is, while BPS may have a somewhat lower estrogenic effect than BPA. But many scientists think their relative potency is irrelevant because any estrogen disruption spells trouble.

Finally, both BPS and BPF had a much greater effect on the hormone progesterone. Hence the study’s conclusion that the new BPA replacements may cause problems not seen BPA.

blog bpa free 2It is absolutely clear that we should avoid BPA. It is equally clear that we need to look far beyond “BPA-free” to protect our health. And this is possible: Many of Eden’s canned foods use waxes instead of plastic. Puget Consumer’s Co-op (PCC) uses vitamin C treated cash register receipts.

At the same time, others on the “Best Players” on EWG’s list are villains in disguise, having simply switched to other bisphenols. Remember, we need lists of “bisphenol free” products, ” BPA-free” is not good enough. BPA-free list:
