There is no such thing as proving something "safe". Go back and re-read the parent comment. The important point you are missing is that basically anything can be "linked" to cancer, and if you adopt the argument you are making, there would be nothing left.
Proving something safe is logically equivalent to proving that it is not unsafe, which is the same thing as proving a negative, which cannot be done. I cannot prove there is not a teapot circling Mars, and I cannot prove that even the most inert ingredient, at some dose, will not harm you.
Anyone who has lived in California knows this absurdity more intuitively than most people, because California's stupid laws adopt the logic you are proposing, and basically everything in daily life is labeled as cancer-causing.
A lot of folks in child comments are echoing your sentiment that something “cannot be proved safe”. Your argument that proving something is “not unsafe” is proving a negative is fallacious; the same can literally be said about anything (proving something is X is the same as proving it is not not-X). Proving drugs are safe and effective is literally one of the jobs of the FDA. If you do not believe that is possible, then we may as well tear down the entire drug regulatory apparatus. I imagine you and many other commenters will sing a different tune when posed with that suggestion.
So, let’s stop pretending it’s not possible. We require drug companies show their products are safe and efficacious, and there is both a scientific and a legal framework by which we do this. Let’s debate whether or not the same framework should be applied to food additives (I would argue it should) rather than claim it is not possible.
