As you may know, Bisphenol A (BPA) has many bad qualities. Plastic manufacturers use BPA to harden plastics such as those used in plastic water bottles, canned goods such tomato products, and items used for babies. Additionally, plumbing suppliers line water lines with BPA! In fact, Bisphenol A was used in most food grade plastics for over 40 years.
BPA acts as a hormone (estrogen) mimic leading to abnormal levels of hormones within our bodies. Scientists suspect that it can affect the brain – especially of babies and children – as well as increasing heart disease and having possible links to obesity, cancer and diabetes.
After pressure from the FDA and consumers, the plastics industry has switched many products to Bisphenol S (BPS) instead. The difference between the S and the A version is what molecule holds the two halves of the molecule together. In Bisphenol S it’s a sulfone group (SO2) whereas Bisphenol A it’s a dimethylmethylene group (C(CH3)2). So if the problem is the dimethylmethylene group substituting a sulfone group would solve the problems… only it looks like that’s not fixing the issues.
New Research on BPS
In a new paper published in PLOS Genetics by UCLA researchers warns that not only does BPS still damage a woman’s eggs like BPA, it does so at a lower concentration! While researchers, led by Yichang Chen, worked with worms, the results should apply equally to humans.
“This study clearly illustrates the issue with the ‘whack-a-mole’ approach to chemical replacement in consumer products,” said Patrick Allard, assistant professor of environmental health sciences at the UCLA Fielding School of Public Health, and the study’s senior author. “There is a great need for the coordinated safety assessment of multiple substitutes and mixtures of chemicals before their use in product replacement. But the good news is that a number of governmental programs and academic labs are now moving in that direction”.
- Get a BPA and BPS free reusable water bottle and use it
- Use fresh vegetables when possible or frozen veggies most the time. If you have to use canned vegetables, look for jarred versions especially for acidic foods such as tomatoes and pickled foods which almost always have BPA lined cans.
- Make fresh soups!
- Use silicone, ceramic, stainless steel or glass storage containers
- If you have to buy bottled water – don’t reuse the bottle for potable purposes
- Never heat plastic containers – if your water bottles got hot in the car – toss them.
