|Read about our Airtight Sanctus Mundo Containers in the Toronto Star|
Barbara Turnbull, Living Reporter for the Toronto Star, gives her take on our Sanctus Mundo stainless steel airtight containers after receiving a set as a gift. She liked them so much she even ordered some more. You can read her article in the Living Section of the Toronto Star.
|To BPA or not to BPA...|
...in short: NOT. Within the past few years, Bisphenol A (BPA) has become one of the most well known household chemicals in the world. And with good reason.
What is Bisphenol A?
BPA is a synthetic chemical and the primary constituent of polycarbonate plastics and epoxy resins. If you're into the technical chemistry, it is created by condensing acetone and phenol, and is known as 4,4'-dihydroxy-2,2-diphenylpropane; it's chemical structure looks like this:
Well over two million tons of BPA are produced globally annually, and some expect demand to rise to over six million tons by 2015.
Where is it found?
BPA is literally everywhere, including the air. It is commonly found in baby bottles, food and beverage can liners, pacifiers and baby toys, water bottles and large water cooler bottles, cash register receipts, flatware, safety equipment, eyeglasses, dental fillings, computer and cell phone casings, compact discs, DVDs, and epoxy paint and coatings.
Why is it a concern?
BPA is a concern because it readily breaks down and leaches from products made out of it. Plastics and resins made of BPA weaken, and thus leach more BPA, when they are old and wearing out, heated or frozen, washed with detergents, and exposed to oily or acidic foods and liquids. Thus, BPA leaching is especially a concern with canned foods, which often are oil-based and/or acidic.
BPA is often described as a hormone or endocrine disuptor, because it
mimics hormones, in particular the human estrogen hormones, which are involved in normal cellular function, reproduction, development and behaviour.
Peer-reviewed scientific studies have linked BPA to numerous health problems including chromosomal and reproductive system abnormalities, impaired brain and neurological functions, cancer, cardiovascular system damage, adult-onset diabetes, early puberty, obesity and resistance to chemotherapy. Research into the impacts of BPA on human health is extensive and ongoing.
Since BPA has begun to be recognized as a problem chemical in consumer products and been banned in children's products in some countries, a profusion of "BPA-free" baby bottles have entered the market and are made of other plastics, for example polyether sulfone. The fact that a plastic product is made of a non-BPA plastic, does not necessarily mean it is safe. There tend to be few, if any, available research studies on such replacement plastics. And researchers have shown, that some 'BPA-free' products actually exhibit more estrogenic activity than plastics containing BPA.
The Unique Dose-Response Characteristics of Bisphenol A
"The higher the dose, the greater the effect" is a traditional assumption that emerged hundreds of years ago in the field of toxicology, the study of the adverse effects of chemicals on living organisms. Public health standards have been, and largely continue to be, developed based on the idea that high dose research will adequately predict potential low dose effects of a toxin on health. BPA does not follow this assumption. Solid scientific research using animal studies is increasingly showing that even very low doses of BPA can have a significant effect on health and can even irreversibly alter fetal development. Low doses of BPA are typically found in the environment or through exposure from BPA-containing materials in everyday life, such as plastics and can resins. One of the leader's in this field is Dr. Frederick Vom Saal, a biology professor at the University of Missouri and specialist in endocrine disruptors such as BPA.
