All plastic releases chemicals into the near environment as well as adsorbing same from near as well. You can easily test this on your own using your sense of taste. What is coming out depends upon how old it is (as well as the type of plastic). I think it is better to match the plastic to the purpose that closely matches what it was made for like Reynolds cooking bags.

In my mind, there are two kinds of food; food for sustenance alone (most store bought energy bars fall into this category for many people), and food for enjoyment and sustenance. For myself, freeze dried eggs always need something added to them. In fact the more added the better. Plain fd eggs is sustenance, but make a Denver omelet out of them and I start liking 'em. Like Oldranger said...need more hot sauce!
