BPS, like BPA, disrupts estrogen and thyroid hormones.
BPA-free plastic alternatives may not be safe as you think by Sandee LaMotte February 1, 2016, CNN http://www.cnn.com/2016/02/01/health/bpa-free-alternatives-may-not-be-safe/index.html
BPA-free alternatives may be no safer than BPA, say
researchers. Most common alternative, BPS, linked in study
to disruptions of estrogen and thyroid hormones
(CNN)Your "BPA-free" plastic product may be no safer
than the product it replaced, says a new UCLA study that analyzed the
impact of a common BPA alternative on zebra fish embryos. The study
joins a small but growing group of similar research sounding the alarm
about so called "BPA-free" alternatives.
"Our findings are frightening and important," said
senior author and reproductive endocrinologist Nancy Wayne.
"Consider it the aquatic version of the canary in the coal
mine."
After decades of animal research linked BPA (Bisphenol A), a
known endocrine disruptor, to problems with brain and reproductive
development, early puberty and a rise in breast and prostate cancer,
many manufacturers stopped using the chemical to harden plastics,
replacing it with "BPA-free" alternatives. The most common
replacement is BPS (Bisphenol S), said Wayne....
...The Breast Cancer Fund recommends that consumers wishing to limit
exposure to possible toxins in BPA, BPS and other alternatives use
glass, stainless steel and food safe ceramic containers for food and
water storage. They stress that it's not safe to microwave in plastic.
Other suggestions include using gloves to handle thermal paper
receipts, and researching canned goods to find those that no longer
use plastic liners.
