That's interesting to me because I know for a fact that commercial baby food is augmented with what are effectively liquid plastics, i.e., petroleum based food "fillers". I know a scientist that ended up resigning quite a bit of time ago now from the parent company because of his resistance to pushes to "research" the maximum amount of "food safe" plastic liquid filler that could be added to baby food without having immediate and/or apparent health effects on the baby.
Yes. I know that sounds fantastical, but it is so. And no, he did not feel like being crushed and ground down like a bug in processed food by "speaking out" or "whistleblowing". Those are terms that are nice, but reality is often quite different in practical terms, especially when industries have captured and/or have agents inside the regulators and the government itself.
