good New Year's resolution was to drink no more of PET bottles, as I am of the opinion that I already take enough estrogen to me. Unfortunately
me another little connection now also spoils the mood for juice tetra: bisphenol A. It sounds strange and complicated, but sits in front of the screen while you read this. And is also in house dust under your desk.
It is a chemical compound that is synthesized by including acetone (acetone Does that ring a bell Correct:? That is in such beautiful things like nail polish remover included) and as a basis for the production of various polymeric for plastics.
This is also the explanation why bisphenol A at all enters the body: in the food industry, canning, beverage cans, Tetra Paks, bottle tops and lots of other things that you need every day, covered with bisphenol A. It is taken up not only by the skin, (supermarket cashiers have a demonstrably higher concentration in the body) but also via the food because it is (sometimes faster, sometimes slower, depending on condition, for example, accelerate heat or carbon dioxide to the process) before all dissolved in liquid.
Only Once inside the body, it develops a similar endocrine effects such as estrogen, which has particularly devastating consequences for the production of sperm, not only are less educated them in the smaller amount is also more sperm from fertilising or carry damaged DNA. And if that were not enough, it also provides for an increased risk for diabetes, obesity or generally the metabolic syndrome. In experiments with monkeys also showed that bisphenol A is the cross-linking in the brain, thus limiting learning. Since
are all generally rather unpleasant effects, you should take care to avoid bisphenol A as far as possible. Unfortunately, the inscription "PC" as an abbreviation for polycarbonate (in its preparation Bisohenol A verwendet wird) nicht verpflichtend. Manchmal hat man aber das Glück, im Recyclingzeichen die Ziffer 7 zu entdecken, die für "andere" Kunststoffe (häufiger sind die Ziffern 1 - 6) steht.
In PET Flaschen ist Bisphenol A übrigens offiziell nicht drin, im darin enthaltenen Wasser aber sehr wohl, da die Verbindung fast überall nachgewiesen werden kann, weil sie nun mal Teil unseres Alltags ist. Dafür gibt´s in PET den ein wenig streng riechenden Stoff Acetaldehyd, aber das ist eine andere Geschichte.
