Aspartame is profoundly safe and there is no mechanism through which it could be unsafe in the human body.

I think there’s more and more research coming out disproving this. Aspartame’s flavor can cause insulin release from the pancreas which lowers your body’s insulin sensitivity.

Well, there's phenylketonuria. (That's not relevant to the vast majority of people, but it's an extremely important exception.)

Phenylketonuria is an inherited genetic disorder. Aspartame doesn't make a food unsafe to those who do not suffer from this genetic disorder any more than peanuts do for people who do not have nut allergies.

Where has that been demonstrated?

Aspartame is one of the most ridiculously well-studied food additives known to humankind.
