It's so weird to say "unproven" when you're talking about a 1000 chemicals, because statistically the odds that they are all harmless seems negligible.

Also strange unfair exercise you're setting up -- that we can't be upset about chemicals if we aren't exercising?

How about instead -- the FDA finds a short list of proven safe food-grade wrappers, and we all pay the extra 1 cent per product to use those? I really cannot understand your mentality at all here.
