The preservatives are fine, if your body is a plastic bag, but of course it is not. It is much warmer and the food will be exposed to oxygen, iron, etc. Depending upon the product, free radical degradation can occur at an alarming pace once outside the packaged environment. Also, when you cook something at high temperature while exposed to air, you are going to blow out whatever antioxidant cover that once existed. And of course it is often the case the proteins are damaged during processing. Basic stuff, right? merlijn spinnewijn <[email protected]> posted: "I don´t understand it.
