When it comes to things that we put in our bodies and affects a large portion of foods in the store, I'd like to see stricter regulations and, if needed, more studies, so that 4-5 decades don't pass before we learn something is super dangerous for our bodies (like say processed vegetable oil, which was promoted by special interest groups without evidence [1] of being healthier).

I think the onus and liability should be on the companies "inventing" new food stuff to prove that they are safe to introduce on the market before actually doing that. I mention liability, because if the stuff is later found to actually be dangerous and it's found that the companies lied/were misleading with their own studies, then people should be going to jail (no, not just fines, regardless of how big they are - we know they aren't going to bankrupt the company anyway).
