I'm all for evolving our knowledge of substances and their effects, but as other accounts are saying, we have more questions than answers

And here's my problem with it: ok we figure out substance X has problems and we go and replace it with Y (which has less research on it than X). Are we sure this is a better replacement?

We're talking about food packaging, what happens if we replace substances and end up with a lower product shelf life (which might be acceptable or not)? Or with other issues?
